I practice intermittent fasting. I don't eat during the hours I sleep. :)
😆😆😆
Lol, true and you BREAK your FAST ever morning, right?
😂😂😂 Yes!
😂👍
good joke, but some statistics say that we eat about 8 spiders per year during sleeping😂
It’s also worth noting that most studies that have shown fasting to be safe have actually only been conducted on groups of young, healthy males and NOT women.
I appreciate you addressing the fact that some of us don't care about fertility. Seems like it's always a given that we eventually want to get pregnant.
This! It kinda irks me out sometimes when diet/fitness approaches are presented with the goal to be like MAXIMALLY FERTILE at all times. Obviously we want normal periods and hormones, but for someone like me on continuous BC for the foreseeable future anyway, it just doesn't really apply at all
Good point. I don't want my hormones out of wack but I don't care about my fertility. I have 2 children and paid to have my husband made infertile.
And many of us are very much finished having children. I have 3, I no longer care about my fertility, it's done it's job. If you consider both women that don't want children and women that have finished having theirs, that's a huge proportion of the uterus having adult population
Right? Due to the latest anti-woman rulings, I got my tubes tied BEFORE HAVING CHILDREN. I don't want them, don't want to adopt. Too complicated with my mental health issues.
Thank you! X
I've been doing a non extreme form of IF. My eating hours are between 8am and 5pm. I do not restrict any food groups, I eat mostly healthy, still get some treats, and lost my 15 pounds of pandemic weight (at a rate of 1 to 2 pounds a week). This has helped me form better habits, made my digestive system happier, and I appreciate my meals more!
I'm glad that works for you!
I eat 10:00AM to 6:00PM. We definitely need to NOT eat three hours before bed. This is often referred to as “Time Restrictive Diet” an 8 hour window is completely safe.
Totally agree with you, Rena!
@@rena6895 This is my routine as well. Just not eating after dinner and delaying breakfast a bit gives me the discipline I need to maintain weight. Of course eating healthy as well!
It’s my routine since maybe 2010. 😉 It’s an old habit i will keep for many more years.
I was overweight my entire life. I am a woman. I did IF for the past year and a half and I lost 130 pounds and I am officially no longer overweight. I am in my early 40’s so I am at a point where my cycle may start changing because of age. That being said, I have not suffered any abnormal cycle side affects. I do a 16/8 fast and at a point where I am just maintaining. My BP and labs are perfect. This is just my experience. This fasting is the only thing that ever worked for me.
Awesome job💕💕
Did you do 16:8 throughout your whole weight loss journey?
What exercise or workouts did you do?
I have a very similar story to yours. I ate keto for years and then moved to IF where I had more freedom and less restrictive energy. I’ve never been healthier per my panels, doctor, and overall health.
Same for me. I don’t really call it IF but very often I try to keep my eating window between 9 or 10 am and 5:30 or 6 most days of the week and eat relatively simple meals most often. I’m 100 lbs down and do this whether I’m in a deficit or at maintenance and have been maintaining weight loss for 2 years. I’m not rigid about it or that starts leading me to binge eat. If I’m SUPER hungry outside that window, I’ll have something to eat and try to focus on overall consumption on those days. This just helps me stay in an appropriate calorie intake for myself and I’m approaching 40 years old and haven’t had any noticeable problems with hormones and my labs have steadily improved as I lost and maintained weight and improved my exercise consistency (weight train 2x’s per week and cardio 2x’s per week with daily steps around 8-10k)
Me too. IF is the only thing that ever worked and also comes very natural to me.
I have struggled with bulimia, and while I understand that IF works for some....I could never imagine doing it. It would be SO triggering. I sincerely wish there was more conversation about this, because I know so many people have disordered eating and disguise it as IF.
You’re right, I tried… and I failed, because eventually, you’re obviously unhealthy…
@@heatherknits124 I'm thinking about starting intermittent fasting but I had anorexia in the past so I'm kinda scared, it might be very triggering for anyone who suffered from an ED
@@julilovatica1998 Everyone's ED experience and recovery is different, but I actually found it helped me stop obsessing about food, because I didn't have to think about it most of the time.🤷♀️
I could never either, I completely understand!
@@julilovatica1998 You must be very cautious. Talk with your doctor. A huge number of professional workers don’t really understand that in anorexia nervosa, the brain senses reward from the negative reactions in the process… our brains aren’t seeking pleasure the way others do, and it makes treatment very, very hard! Fasting overnight is normal, you can’t eat while sleeping. But while the sun is up, and you’re living your life, that’s your eating window. Missing and skipping meals when you are battling the demons of anorexia nervosa means letting them win- and you end up with brittle hair, weakness, exhaustion, shaking, numbness, you know the list goes on, so DON’T let the demons win.
As a mother and a grandmother, I’m very picky about what my daughter and her daughters eat. During this infant formula recall recently, I forced my daughter to switch her brand new newborn to breastfeeding, to ensure a supply of proper nutrition (hospital staff had begun bottles because she was tiny, not malicious at all) and, I routinely transport food from where I live to them thirty miles away, this month it’s been cows milk and macaroni. While at their grocery stores, I bought chicken gizzards for myself. Times are a bit different, and I have a food demon screaming to just fast, it’s not worth it. But it is, because I failed. I can’t let my children suffer, or their children. Some of the best that has come from it for me is that, because I transporting food, I’m also teaching my daughter to cook. Dry beans require soaking. If pancake mix isn’t available, you have to blend flour, sugar, leavening, milk and eggs. Then I’m forced to be social and eat with them, instead of making the food and getting rid of it any other way.
Basically, talk to your care team before fasting longer than overnight. As a woman, your fertility is at risk. You don’t want that.
IF made my period cramps disappear. I have upper stomach endometriosis and PCOS and the pain used to be so bad I couldn't stay still at times. My periods are also not as heavy anymore and are very regular. It's been life changing for me. I suspect insulin resistance was the culprit.
It could be. What I've also noticed in the weight loss community and the body positive community is that a lot more women in the US have PCOS. I looked up stats in my country and the US and sure enough, more US women have PCOS. I wonder if it's because a lot of things go into American food that aren't even allowed to be used in the EU.
I'm glad that was helpful for you!
@@smorevids being overweight really messes up the hormones, which is why probably there is more PCOS in USA and UK
@@dariabryksabeing overweight is not a cause of PCOS, is viceversa.
PCOS is a double edge sword. It causes you to be overweight, which makes your PCOS symptoms much worse.
As someone who lost her period for a year before, and fallen victim to the purist keto and IF side of the internet, this video is a real breath of fresh air.
I would also like to know about the effects of IF for menopausal or postmenopausal women, as they seem to be targeted a lot by IF promoters. My mom is in that boat as well and swears by IF, and I hope there's not too much risk to it.
Same.
Menopausal women must have a greater risk because of their calcium requirements
There is no risk for postmenopausal women as long as they do not restrict their foods during their eating window. Cynthia Thurlow has wonderful information about fasting in a way that works with your hormones.
I am 57 years old and I have been doing intermittent fasting for about five years now. It has changed my life for the better. I went from an eight hour window of eating to a four hour window of eating by following Dy Ann Parham’s dprogram, which is called “for today’s aging woman” please look her up. Seriously changeso many women’s lives by helping them learn how to intermittent fast and a very slow and controlled way. I struggled with bulimia in my late teens and early 20s. Doing intermittent fasting has not triggered my bulimia.
I’m a peer mentor and work with ED recovery warriors and have experience recovering from an ED myself. Your videos came up this week in conversation with a patient and I’m so glad your content is available for those trying to unlearn diet culture and recover from EDs! Thank you!
Thank you for sharing, I’m so glad to hear that my videos have been helpful! ❤️
This video was really helpful! I’ve been doing my hunger crushing combos but have still been ravenous and binging. This was the missing piece that I needed. Thanks Abby!
I’m so glad it’s helpful for you! ❤️
Coming out of anorexia, I learn that no one can outsmart our body. It is amazing and would fight for survival no matter how controlling you think you are over it. I first started increasing my portion a bit, but soon experienced extreme hunger because I was deprived for so long and my entire hormonal system was messed up (I lost my period and loads of hair and my joints sore badly, HA can lead to osteoporosis). I recall a period of true struggle because I ate so much to the point where I was about to pop, I was scared and confused whether I was developing another ED aka binge disorder, or whether that was just a natural reaction of my body to refeed itself. I found this channel, read books and educate myself on HA, extreme hunger... and pushed myself reallyyyy hard to never restrict or compensate for the "overeating". I was determined never to fall back into the vicious cycle of binge - guilty - restrict - starve - binge -..., so I tried to convince myself that it was OK, allowed myself to eat to satiety unconditionally in a hope that tomorrow, or next week, or next month, my hormone would regulate and all this extreme hunger would wear off. As I ate more regularly, ate when my body wanted to even at excessive amount, it started to trust me that I wouldn't starve it, so the urge to devour everything like the "last supper" quiet down. I was hopeful and so lucky me I got my period back just last month. I felt soooo alive, and strangely, since I got my menstruation back, I notice I don't overeat anymore. During extreme hunger I could eat highly-processed food and snack nonstop but now I can eat regular meals with moderate amount of snack without obsessing over them all day. My energy is also replenished and I feel so much happier and productive in work, exercising and socializing. Is this what food freedom feels like? Is this the magic that hormonal balance brings to your body? I am grateful to finally get here and regret not appreciating my body enough back in the day. I thank it for giving me a chance and I will not fail it again.
Sounds amazing 😍 I have lost my period two years ago and I honestly don't know why, but I'm so scared of the consequences... When I lost it, I wasn't underweight, nor did I overexercise or have huge psychological stress.
That's why I am scared of eating even more and gaining more weight because it might not be effective, you know?
@@summerv6602 because of stress, restictive diet, diet mentality... you may be restricting and undereating (intentionally or unintentionally) and that can cause hormonal imbalance and daily calorie availability deficit like Abbey explained in the video. Just because you re not underweight does not mean your body does not deserve more nutrition and care
Absolutely. Thank you for sharing your experience with this!
I relate to you so much, I lost my period 2.5 months ago and i feel miserable, i restrict myself a lot, last week i had a binging episode, i don't know what to do, I'm really really lost
@@christinashomaly you binge because your hormone (ghrelin/leptin and others) are imbalanced. Due to chronical restrictive mindset your body is in distrust and it feels the need to "store" as much energy as it can to prepare for "the next diet". This happens because you're out of tune with your body and always low key promise or threaten to restrict, compensate or "diet starts tomorrow". Your body doesn't give a shit about social standard of beauty, it will always instinctively fight for survival, when there's not enough nutrition and energy, it will shut down other productive function such as menstruation, hair/bone grow and reduce your metabolism to hold on to the very little energy you allow it to have (as a result you burn less calorie than you used to if you didn't over restrict in the first place). The only way out is to fight fight fight that restrictive voice in your head, get rid of that diet mentality and prove your body it can trust you. Eat until it satisfies, today it might go overboard and eat past comfortableness, but believe that if you keep going, keep eating regularly and listen to it, it will trust you, the period will come back and only then can your hormone and appetite be regulated. You're not binging, you're experience extreme hunger and this is normal to refeed yourself, never say "I'm so guilty, I ate too much last night/last time so tomorrow I shouldn't eat as much" because that narrative will cause "the last supper" syndrome (your body will eat like this is the last time it is allowed to). Just keep eating and eventually the urge to binge will wear off, trust me, you'll not binge forever. The goal now is to get that period back and keep it stay there regularly.
Not everyone is doing intermittent fasting for weight loss. I am doing it for cellular healing, mental health, mental clarity, happiness. I am not overweight. I F has changed my life for the better and too many ways to list here. It is not for everybody, but for those of us that it works, for it is like a miracle. In addition, you save a lot of money on food. In a sense, I wish I could eat 3 to 6 small meals, a day, but I know myself, and that would not work for me because once I start eating, all I want to do is eat. I have tried this in the past, and then all I do all day is think about food. I don’t do that with a F, because I know that I’m in my fasting window. I am so glad that Abbey’s work works for a lot of people.
IF doesn’t have to mean skipping meals. I have breakfast at 8am, lunch at 12am and dinner at 5pm. It works for me as I hate the sensation of going to bed in a full stomach.
I’m glad that works for you!
Same for me, it allows me to forego the temptation of snacking at night and have a way better sleep. Now I don't even think about having any food at night and I save money on snack food!
same here. My sleep is really bad if my stomach is full
Yes but you have nice spaced meals and there are those who eat one meal at the end of the day after like 20 hours of fasting. That sound to me like pure torture.
@@ligitamikelyte1693that's not IF. That's starvation. To do IF properly you're still supposed to eat 2-3 meals a day and ensure that you're getting enough calories. Your eating window is just smaller.
Thank you Abbey, this was incredibly helpful and very well explained. So insightful and crucial for female health. So much confusion out there around fasting etc, and as a very lean & active female this is something I need to be more conscious of. It’s very useful to see the day energy expenditure as I hadn’t thought about it like that before! The body is so complex!
This video is so helpful! I once tried intermittent fasting to lose weight but I started getting irregular periods and feeling tired ALL THE TIME. I got really worried, so I stopped and got back to my regular eating habits. It was until recently that I learned that these types of "diets" can be seriously bad on some people. Thanks for sharing your knowledge 🙏🏼💕
I’m so sorry for your experience! Glad you found the video helpful 😊
Super helpful! Thanks for that deep dive into the science ☺️
This was very insightful. Thank you, Abbey!
Hi Abbey! I would love to see you discuss the other (purported) benefits of intermittent fasting beyond weight loss. I've heard that it supports longer lifespans and fights cognitive decline, which would be great if true.
I also LOVE the videos you do about "fear foods" and I'd definitely watch more of those!
!!! the calorie within day deficiency concept shed so much light on why I had to switch from IF to eating consistently for my mood and hunger (especially during weight-loss periods)! Thanks for sharing. Mind-blowing stuff.
cant wait to watch this!!
I hope it’s helpful!
I would love to see you address ways to eat when you’re close to menopause and in the midst of late stage perimenopause. I feel that there has been a lot of talk about increasing one’s protein intake, but find it hard to get it all in without supplementing with a protein powder. I personally don’t like to have to rely on protein powder and would rather eat real foods to get my protein intake. I hear that dairy isn’t good for you, but cottage cheese and Greek yogurt can really help me get closer to 30 grams at each meal. Uff da!!!!! So many questions, so little time. Plus, your research on this will help you in the future!!! 😉❤️
Totally agree (with all you said)! It’s a very frustrating time in life- and there is such conflicting information out there. You just don’t know where to turn and feel like nothing works anyway- it’s easy to just give up and accept feeling bad :(
Dairy has casomorphin which is what makes you addicted to it. And it has casein which is what causes cancer. Abbey Sharp is for sale by the meat, dairy, and supplements industry. You trust her and you are going down a terrible road for your health. Stay away!
@@robertmuldoon9783 hmmmm, and I simply CANNOT imagine a fulfilling, satisfying life without REAL dairy, like milk and cheese, etc., which people have been consuming for centuries. That being said, satisfaction and nutrients being set aside, please share the source of the information as I truly want to be around as long as possible for my future grandchild expected in the near future 😀.
I can put this topic on my list to discuss in a video!
@@AbbeysKitchen thanks so much!!! I would really appreciate all the information you can give on this topic!! 😊
IF helped me actually regain my health, lose baby weight and trauma-stress weight, get over disordered mindless eating, feel comfortable to be on the go without needing to waste time digesting for very long AND lowered my insulin resistance that came from eating 5 small meals a day - I now eat twice a day breaking my fast and before the end of my window. I personally find IF the best most free solution to many many problems.
Most of the time when people mention IF it's the 16:8 window, which isn't even that 'insane' if you think about it. Assuming we sleep 7-8h a day, then add another 4h after and before bed, there's people who do that subconciously. I do eat 4-5 meals a day, but I also burn significantly more than average (high muscle mass, active job, active hobbies).
I resort to having a 10:00-18:00 window or even OMAD when my movement or food choice is heavily restricted for a while, the latter definitely causes issues but 16:8 I did for years without problems (and back then no coil, so I had my cycle and it was very good, much better than when I was an obese kid.) It's important to be aware of the risks but 8h is a huge window still.
Ren, which IF regimen did you follow to achieve all this?
So informative. Thanks so much for what you do!
I would love to see a video on food journaling. Pros and cons, etc. Thank you!
What an awesome video! I learned that I have a lot to learn about safe calorie deficits. Thanks for another great one Abbey!
So glad it was helpful!
Thank you for this video. I would love to see more content on energy availability. I’m in recovery from binge eating, and I’m a former streak runner [14 years]. I’m working on healing my metabolism, with which your content has been very helpful! Through this video, I’m starting to see just how much my metabolism and hormones have been affected by my old lifestyle. I def spent a lot of my life in a state of low energy availability. (I’m not one for intermittent fasting, per se, but pretty much everything you say in this video is right up my alley and super helpful in my recovery.) So I would be really interested to hear you speak more about the ideas you present here. And I vote for more graphics/diagrams! They help me see the structural foundations of related dietary concepts. Thanks for what you do!
I think it's the same as everything else to do with human nutrition: IF will work for some, be neutral for some, and be harmful to others.
yes!! love iherb!! i need to place an order soon too :)
This is soooooo interesting!! Thank you so much for this video 👌🏻
So glad it was helpful!
I did IF and keto for about a year, by the end i had developed hypothalamic amenorrhea and low thyroid symptoms 🙃 i was only doing 16 to 18 hour fasts daily.
3 months on a fully nourished protocol reversed all that and i got pregnant.
Don’t mix if and keto together lol. Two completely different things. Your issues stemmed from malnourishment which is most likely from the Keto. Keto is a hard diet to keep up with and it’s macros and micros are so imbalanced
I’m so sorry for your experience. Congratulations on your pregnancy though! 😊
@@JamesTaylor-cl4pq I hate when people say they have gone on keto. It's one of the worst trends ever. It's not even sustainable and there's people who have been on it for years and years! Totally crazy to me! 😩 *if* you even do it it's supposed to be done in a small period of time. Def not a permanent "diet" or imo, healthy in any way.
@@lovelesswing458 keto is a good diet if you're not using your brain and want to starve it.
@@lovelesswing458 I sooo agree!! I HAVE to be on a low-carb-keto diet because of insulin resistance and it is sooo tough. I wish I could eat like a normal person. I don't understand this trend of being on a keto diet if you don't need it.
Brilliantly explaned! Thank you! 🌷
Thanks! ❤️
I’ve been doing 16:8 IF for almost a year and it changed my life for good. I don’t do keto, I simply try to have a balance diet during my eating window, including treats now and then. I used to have lots of digestive issues and they have dramatically reduced since I started IF. The first month was hard, but then my body got used to it and I’m very glad I didn’t quit just because it was hard at first. It changed my relationship with hunger; I’m no longer my hunger’s bitch. I used to get so irritable if I didn’t eat at a certain hour of the day, now my body is used to using my own fat for fuel, so I can skip a meal without getting cranky or feeling weak. I rarely have cravings for snacks now, and when I do, I allow myself to have whatever I’m craving, with moderation. But, most days I don’t snack, simply because my body doesn’t want it. My periods are regular. I’m not saying IF is a magic tool, but it does help, a lot.
same lol im glad i stuck to it and yep, dude u can be proud of yourself..the begining was hard, but as u said, the body gets used to it
Thanks for another great video Abbey! I’d love to see you discuss the Weston A. Price foundation and their health recommendations!
I’ll have a look at that!
I wish you had said something about autophagy and inflammatory constant insuline spikes due to several meals. I’d love your perspective on it bc that’s what fasting ambassadors advertise with
Thank you for addressing this!! I feel like this risk is just glossed over by big advocates of IF
Thank you for educating me! 🙏
I hope you have a beverage of choice and celebrate the good you do sharing these videos. A coworker last Wednesday morning said she was breaking her fast she started on Sunday 😦. These fasts are a seriously scary trend
Agreed!
Interesting video, I do feel like this video operates based off of the assumption that the individual in question is not eating enough calories within the 8 hour window.
So if someone is just not eating enough food in general I can see the correlation between that diet and the hormonal problems, however if they are eating a sustainable amount of food I don’t believe it would yield these results.
Exactly this. I did IF for 15 years (not for weight loss) and I can attest to the fact that there is a right way and a wrong way to do it. Not eating enough will screw you up.
Also, if doing any form of fasting because of severe overweight, talking about "energy availability" without taking into account all the energy stored as fat is a bit weird. The type of hormonal issues one tries to fix when morbidly obese are very different from the ones to be fixed when underweight. But even for someone not overweight, this number of the punctual 300cal deficit just cannot be true - if it was one would have to warn women away from any kind of endurance sport.
Yes IF doesn’t directly mean that you are not getting enough calories…
I've been binge-watching Abbey content for a while and I really appreciate the approach and the way it evolved during time.
I am kind of bothered with IF being called a diet in a lot of videos. I understand people sometimes use it for weight-loss but it is not concepted as a diet and it has nothing to do with what you eat, it is only various types od timeframes for eating considered for health benefits - I first heard about it from tough work-out kind of guys not remotely interested in weight loss but in getting the best from their bodies and improving.
The main point is that circadian rhythm does make some sense for people who find themselves grazing for example late at night for no nutritional reasons but boredom, food being near by and etc and sometimes just trying something like that and seeing how body reacts makes people realize when they are hungry and when its just not necessary. and when you think about it its not some kind of long fast, it's basically "sleep time" :D. or a kind of popular 8-10 window if it suits them ,it is pretty flexible because you can see what suits your lifestyle, are you a breakfast person so you make it earlier or not, like me, who never was hungry in the morning but constant "breakfast is most important" propaganda made me think i had to eat it in the morning, when break-fast is just what you break your fast with, it can be later :D . for me 12-8pm window is best. but it doesnt have to be strict, if i feel hungry or have a social engagement, i can shift it, but letting body "rest" from constant digestion for a while does make me feel better, lighter in a way, and more mindful of my eating.
I normally eat sometime between 7:30 am and 6 pm, so about 9-10 hours. I've never called it IF or a diet. It's just how I was raised. My dad used to be general in Vietnam military. Sometimes I just eat when I'm hungry so that means maybe waking up late and having "breakfast" at 12 pm, skipping lunch, and finishing off dinner at 6 pm so within 6 hours. I've never lost my period. The only time I lost my period was when I went vegan for three months ☺️ 😅. I don't understand the obsession with eating 3 square meals a day plus snacks in between unless you have some type of health condition (physical or mental). I honestly believe society is so food focused. My grandparents lived through wars and famine, eat when they can, focus on other issues in their life. They are pretty healthy in their late 90s, approaching 100 soon. I compare them to my mom, the single person who eats throughout the day, grazing with meals, very food focus, eating typical American type of processed foods. She's also the only one in the family with diabetes, heart disease and history of cancer. I think that should be the main issue talked about.
Great info Abbey! Thanks.
😊👍
You're 100% right. It totally messed up my hormones. All these docs on CZcams say how beneficial and safe it is, yet here I am. I'm a total mess after 2 months of IF. How long is it gonna take for me to fix it?
I love these analytical, science heavy videos!
I wish this had been taught and discussed when I was in college. I know women specific health, nutrition, and fitness is a relatively new field of study, especially in the male dominant fitness industry, but a lot of women are being done a disservice by not knowing this type of information! If this information had been provided to me earlier, I likely wouldn’t have gone through 5+ years of orthorexia/anorexia, amenorrhea, bone density loss, and a stress fracture. I’m just glad that I know it now, before I’m 25, so I can reverse as much damage as possible.
Thank you Abby for educating young girls online not to fall for any trend that pops up. I wish I watched you when I was younger, unfortunately damage is already done but I'd appreciate more videos on diet and fertility. 🙏🏻🙏🏻
I hope the videos are still helpful now!
Thank you so much for this video!
Very informative. Thanks Abbey. I'd really like a video specifically on diet for diabetics of different ages.
I will put this on my list to discuss!
This is a really great video! As an aging researcher interested in fasting, it is so important that we discuss the effect of fasting on hormone levels! Of course, diabetes and other aging related diseases are of concern and are some of the main diseases that this can treat which is great. BUT Abbey is saying we need to consider this factor as well that most people don't think about. It also doesn't help that a lot of fasting studies have been done in male lab animals, and I hope now that we can really untangle sex differences within different types of fasting
I started a phd program a few months ago and none of us in the lab have ANY time for lunch (I have a hard time getting enough water in at this point) and I 100% lost my period. I believe that for those of us sensitive to available caloric energy will experience this and that we should just all be mindful
How is that even “legal”?
Who does the “planning” of the schedules?
In my country, in fact in all countries, there are laws and regulations in place and your university lab would be closed until they fixed it and_heavily_fined_ like $$$$$.
No one would “plan that bad”. Your university is breaking working hours and safety regulations. It’s a systemic attitude and problem that needs to be fixed before someone passes out or dies. It’s a human right and protected workers right to have meal breaks every 4-5 hours of 30 min - 1 hour.
This is not normal work practice in the world.
@@AnnaKaunitz it’s unfortunate I know, it’s also the nature of the type of experiments we run (which I won’t get too into). Technically no one is “making” us but we want to do well and produce results. I think it’s also the territory that comes with graduate school, I know a lot of my peers experience what I do too 😔
@@taraa4281 But…you’re not productive without breaks and food. You’d be more productive if you decided to eat and have a short break every now and then. If you don’t take responsibility now when your period is gone, I don’t know what to say.
I’m so sorry for your experience with this, I hope you are doing alright now!
Please do not sacrifice your physical and mental health for academia. 💜 You are doing permanent damage to your body that will have lifelong health consequences. Please, believe me when I tell you starving yourself has long term consequences. I’ll be dealing with them for the rest of my life.
Please do a video on alternate day fasting … I would love to get your opinions on that ❤️
Thank you for this information, it’s incredibly important for young athletes to know! I wish I knew this as a collegiate runner a few years ago. The athlete triad was always taught to me as not eating enough and being super skinny. I never fit this category but ended up with orthostatic hypotension, low thyroid, frequent injuries, and high anxiety from not paying close enough attention to how often I was eating. Simply eating the same amount but spaced out through the day fixed so many problems.
Absolutely! Im so sorry for your experience. I hope you are doing better now ❤️
I am just very mesmerized by your hair🤩
As usual, a thought-provoking video. Knowing how open-minded Abbey is I am sure she will welcome the following observations (especially from someone who would fall outside the target audience) :
1. IF is used as a lifestyle choice by some who don’t see it exclusively through the prism of weight loss (although I appreciate that the video is looking particularly at its potential effect on female hormones and reproductive health)
2. One of the studies cited was based on a 72hr fasting window, something that would not be representative of the vast majority of people who use intermittent fasting.
3. It might’ve useful to mention the role of weight bearing exercise /resistance training to offset the decrease in bone density from mid 30s onwards.
4. Assuming someone is lucky enough to get 8hrs sleep a night, a 12hr fasting window only involves being awake for 4 fasting hours so not really that extreme!
5. In the interest of balance, some passing references to the potential benefits of IF e.g. autophagy (as detailed by people like Dr David Sinclair, Dr Rhona Patrick and Dr Peter Attia) would help to round out the picture.
As Abbey rightly points out, this is a complicated topic. IF is not a “diet” that suits everyone (If we eat we have a “diet” in the sense of it referring to how we regulate (or not) our food intake).
Keep up the good work Abbey!
Thank you for sharing your thoughts and for the feedback! I’m glad you enjoyed the video 😊
#5 is very intriguing to me too and felt like it deserved a mention.
This video gave me impression everything has potential down sides. I'm now used to eating 2 meals a day within an 8 hour eating window, one meal at the start of that window, and one at the end. I can't sleep anyway if I eat less than 5 hours before bed. I started doing this 2MAD 8hour eating window a few years ago when I read about the insulin response, that it peaks every time you eat, etc. It has now become a habit without any conscious effort on my part. I also enjoy only putting in the time to prepare something twice a day. The idea of preparing breakfast, lunch and dinner and taking the time to eat all 3 sounds like a hassle to me now. Being home most of the time, and working from home, I have time to cook low carb meals. I usually eat soups, salads, stir frys, etc.
After watching the video I'm now concerned my eating habit has a negative effect on my metabolism, on hormone and bone health etc.
Is there a way to win? It sounds like whatever you pick you're putting yourself at risk of something significant.
@@itsalwayshalloweenexceptwh5118 maybe you should consult with your primary care physician and, if it is a possibility for you, a dietitian as Abby recommends.
If you don't have proper hunger cues, you may not know you should be eating earlier.
As Abby mentioned, this is a complicated issue where side effects may or may not show up right away, or years down the line.
Since she said this is a complicated issue that the average person would struggle with understanding and creating a healthy plan of attack, it would be helpful for you to get an expert on your team. :)
@@TestaRosssa_ TLDR: I'm not angry at you, I'm venting into the ether right now.
"maybe you should consult with your primary care physician" and ask them what? I don't expect my primary case physician or registered dietitian to even have heard of the subject Abby covered here.
I'm lucky enough that my hunger cues are functioning properly, so that thankfully isn't an issue.
I do understand what Abby explained in the video, it's just all of these dieting tactics seem to have significant potential side effects. It really sounds like a "damned if you do, damned if you don't" kind of thing.
Any particular food or way of eating is bad according to some people and they can back it up with studies too.
Omni= bad according to vegans because of animal products
vegetarian= bad according to vegans because it still contains animal products
dietary veganism= bad according to omnis and carnivores because it's low on certain nutrients
fish is bad because of pollution and issues with farmed fish
vegetables are bad because of anti nutrients, goitrogens, etc
fruit is bad because of the fructose effect on the liver or something
eggs are bad, and then good again, and then bad again, because every few months a study pops up either for or against eggs
red meat is bad because of that one study the WHO likes to quote so much.
grains and grain products are bad because of allergies, insensitivities, gluten, leaky gut, etc.
high carb is bad because of insulin
high fat is bad because fat is still considered bad by many
I know not all of the evidence is of the same quality, so it's easier to ignore some advice over others. But still, this stuff makes me pretty annoyed right now. All of these people genuinely believe they've found the solution.
Enjoyed watching this video👍
So glad!
I find eating less increases my energy. Food digestion takes up the most energy. So when I fast my energy is high, mind is clear and mood is up.
I’ve never experienced problems with intermittent fasting.
From my own experience it’s benefited my waist line, mental clarity and reduced bad cholesterol while maintaining a healthy blood sugar balance.
I’m not sure why you are referring to a low energy state with less calories. Most people go into a low energy state from an unbalanced, over caloric or sugary diet or are eating too often throughout the day.
The body can’t optimally perform while it’s digesting food. Food takes several hours or more to digest properly. So if your eating 3 squares a day your body is constantly digesting until your ready to go to bed - or even later.
I don’t stick to any rigid plan so if really want to eat an extra meal or enjoy cake I do.
I guess it’s a balance. But 3 meals a day leaves me feeling lethargic and drained.
Again, I listen to my body. For days when I really need chocolate I enjoy it without the guilt but the key is IF my baseline. Not my rigid rule.
I have had the same experience. IF has given me energy I never had before.
I'm the opposite. I need to eat breakfast and so on. From small to medium size meals and relatively often in order to feel I'm alive and I want to be alive and want to do things. But I am following a WFPB vegan diet and plants digest quickly. Everyone is different. ❤😊
This was really interesting and helpful. Can you do more about undereating and overtraining and physical effects, like muscle, hair, skin, nervous system, etc. How can I grow my hair?
Love iherb! My dietitian sister also highly recommends it and uses it herself. ❤️
😊👍
I don’t fast longer than 14 hours and I do “circle fasting”, where I only implement IF during certain phases in my cycle. I can’t imagine eating small snacks and meals, I would never feel satiated and counting calories is SO triggering for me ☹️ I eat a lateish breakfast, lunch and early dinner and on my non IF days I spread it out more. This is a process and I’m always changing things but so far I feel good. My hormonal migraines and acne and cramps have improved significantly!
This is so depressing...ive been doing this for 5 years....lost 30 pounds, lost my knee pain, sleep better with more energy, & recently had my bone density improve.
I do 16 hours but eat throughout the day whatever i want.
Now the bone density thing really scares me....wish I could afford a dietician
This was really a bummer.
You said your bone density improved so you don't have to worry. Diet reasearch always speaks in broad averages and most of the times the research has severe limitations, it doesn't have to apply to you.
I take what she said but it's something for the healthier ppl. I do cyclical keto 3w on 1w off and 20/4 or 18/6 IF. I have lost 25kg in 10 months, my period became regular at 40y/o (I have pcos), and my hunger, cravings are under a control I've never had in my life! I still eat chocolate, gluten but all low carb, berries.... I honestly feel like all these YTbers always talk about extremes and only talk about the "healthy" average. Not the morbidly obese like me, with PCOS, depression etc. IF was a life saviour for me. Keto cleared my head, improved my mood, took away my joint pain.... It's like, what about us? You know?
Also, bone density... What about vit D and healthy intake of calcium rich foods wich Keto is full of? Did she speak considering ppl don't take care of these things?
I wouldn't worry, you appear to be doing fine. I think the studies were on very long fasts - 92 hours not 16.
IF has been shown in some research to improve inflammation, which may be why you no longer have knee pain.
@@sharonthibault8153 no doubt. But cutting grains really made a difference. Rice inflames me for the next three days ajaand on if I keep eating it. Beans and lentils ignite the fires of hell in my stomach. These things are so nuanced. Sometimes I think of making vids about me so ppl can see a different side of the spectrum.
Thank you for this. I never considered IF because I know I am already prone to under eating (can't eat when I am stressed, and prolonged hunger kills my appetite completely), and I want to make it a priority to eat a proper meal every morning, noon and night. Your comment about how undereating can affect your bones in just a few days makes me think of stressful times in my life where my under eating definitely contributed to a lack of energy...
I'm glad you found the video helpful!
Abby, thanks for the info. I might consider changing my IF to 12 hours instead of 16.
Such an amazing video Abby I would love to see you review some of Remi Cruz videos ☺️
It never made sense to me how people try to go against the one thing our bodies definitely need on a daily- eating food and still think it's a good idea.
Totally!
Oh god it's so good to know since i walk a lot to uni and exercise in the morning only (strenght training and cardio too) and start eating at 3 pm. I usually wake up around 5 am, sometimes 7 am so really long period of being active without giving energy at all
The energy deficit argument makes no sense to me. I alternate day fast and I have more energy and not less. Because I have lots of energy available in the form of stored fat. Also, my periods were all over the place... amenorrhea and then occasionally a period that lasts for 2 months. No doubt my weight was impacting my periods. Since starting IF my periods have evened out massively. I would be interested in who was taking part in these studies, if the BMI's are around the average it makes sense that the outcomes are different than for people like me. The idea that calorie availability moves like described makes it sound like fat storage is massively ineffective which is silly. IF isn't recommended for women that are already lean, underweight, have any disordered eating habits or trying to conceive, but if this isn't you, the risks are minimal. You kind of say this in a really biased way. So disappointed.
Thank you for sharing your experience and what works for you!
I have to agree. I was diagnoses with pcos and was overweight. IF worked wonders in reducing my intense cramps and I lost weight. I can see how it would not be beneficial however if someone is "normal" or underweight
Having looked at the studies referenced, my fears were confirmed. Most of the studies were for people with a low BMI or described as athletes whose energy needs won't be indicative of the needs of most of those that take on IF. They were also in the main on people who already menstruate regularly, no study was long enough to see if the effects were long term or permanent (what doesn't affect menstruation in the short term) and some studies were specifically on those with anorexia! Instead, good quality, comprehensive and peer-reviewed studies have found much of the above. IF is safe for those that tolerate it long term, it has no lasting effect on bone health and is beneficial for those considered medically obese or "healthy" in the first place. In short, the same old same old applies. If you are an endurance athlete, underweight or have an eating disorder then avoid IF. Especially IF with eating windows of less than 8 hours, but everyone can do it.
@@gemyem26 I am so glad you put this comment out there. I feel like this video was done with a preconceived opinion that found a study to support itself while ignoring the studies that contradict what she believes. Disappointing indeed. 🤔
Thank You for this video! I automatically ATE a breaky while watching this not only coffe &go
Glad you enjoyed the video!
I ate 500 calories two days a week and the rest of the time I ate what I wanted. I lost 60 pounds with zero thyroid function and kept it off for 5 years now. I found it shrunk my stomach and I had less problem controlling what I ate the rest of the days. It worked for me when nothing else had and I did it with a nutritional therapist and I’ve never looked back.
i really love IF it helped me a lot
I know I’m late to commenting, but this is all fascinating stuff. Would be curious to know your thoughts on Jason Fungs work and autophagy, etc.
Also how does one work with an RD who specializes in weight loss / hormonal health without spending an arm and a leg?
Thank you so much for this video. I’m constantly battling with myself regarding intermittent fasting. I’ve done 18:6, 20:4 and OMAD. The latter two have enable weight loss but also caused me to get awful GI issues (literally dumping syndrome) and I’m sure they caused my hair to thin and my periods to get worse. I have endo and PCOS and I’m in my mid-30s so it’s no joke. I feel like I’ve damaged my metabolism through months of IF and OMAD. Weight loss results weren’t even that impressive compared with normal calorie counting! I am still trying to find balance without guilt or overeating. I also work out every day, so I don’t like the idea of not nourishing my body. It’s refreshing to not have somebody taut the benefits of fasting for women like it’s the secret we’ve all been too lazy and greedy to try!
Hi Abbie! I have a question: you talk about female hormones in this video, but what about Insuline? I've listened other dietitians say that one of the major benefits of IF is an increase in insulin sensitivity so for people with metabolic syndrome or POS or insuline resistants (like me) this may be a really good tool to control glucose levels, etc. Is this true? Or worth it to try compared to the other effects you mentioned? Thank you for your time, loved this video! Here a forming nutritionist!
Hello Abbey, could you please make a video about intermittent fasting and chronic diseases like rheumatoid arthritis?
I've just tried IF. but i found that extreme IF hours (more than 20 hours) may not good for a person who work that require a lot of energy ( a lot of standing and walking here and there). So i think about 12 hours during night is good already but maintaining eat good food and exercise. Well this is just my opinion as a women at late 30's.
Awesome video! Thank you
Loved this video Abbey! Super informative as always! 😊 You mentioned the risk of low bone density and how past a certain age, there isn’t any more bone growth/building. I’m wondering, what are some ways we can preserve / protect our bones from getting osteoporosis or fractures in the future?
Weight bearing excercise, vitamin D/K2
I can put this topic on my list to discuss in a video!
I’ve been intermittent fasting for a year now. 16/8 (eating between 11am and 7pm.) I’ve lost twenty pounds without trying and I feel great. I think I have had insulin resistance though. I don’t think it’s for everyone, but studies show it has a lot of health benefits. Especially for those with insulin resistance.
Edit: seeing a general consensus in the comments that IF has been helpful for those with insulin resistance or PCOS. Perhaps people who don’t have underlying issues don’t tolerate it as well?
I’m post menopausal and dealing with insulin resistance for the first time as well plus inflammatory skin issues. Intermittent fasting has been advised for me too…and a paleo based diet It gets confusing after menopause let me tell ya
I had insulin resistance before and after IF. I lost 30 lbs and initially felt great with IF but after about 10 months I started feeling like I had to restrict more to keep the weight off.
After I stopped, I gained 60 and I wasn’t binge eating or anything. I also have hypothyroidism but it’s been well managed for 10 years.
Maybe just don’t ever stop? It only “got rid” of my insulin resistance when I was doing it.
(And truth be told, I’m not sure it did that because I felt like my blood sugar would go haywire when I did eat and I would be tired.. I think it was more the caloric restriction for me)
Edited to say that I *did* stop IF permanently because it made me cranky and obsessed with food and I was concerned at the example I was setting for my 9 year old).
@@lisajohnson8911 Lisa, many times intermittent fasting can highlight food sensitivities due to the fact that you are eating less often. I wonder if something you were eating during your eating window was causing the issues? Or if maybe you needed to lengthen your eating window? That may noy have been it.... just wondering if changing what you were ating might have relieved some of your problems. Through fasting, I have discovered that I am sensitive to cheese and to processed baked goods.....
I do not have PCOS and I tolerate intermittent fasting very well
@@lisajohnson8911 and you probably started eating, processed sugar, flour, etc. and lots of carbohydrates again? That’s why you gain weight probably, now because you stopped IF.
I don’t know if you’ve done this. But I’d love to see a video on if not eating gluten when you’re not celiac is really a benefit or not. I feel like a lot of people (especially health CZcamsrs) make gluten a bad guy even though they’re not intolerant or celiac
A lot of prominent IF advocates have revised their stance to include a consession that women need to fast differently than men. It's starting to become rather common knowledge in the IF community that women should not fast in the luteal phase of their cycle. That is, in the second half of their cycle, where the body ramps up progesterone production. In fact, in the 7 days before a woman's period starts, she should not even fast longer 12 hrs. In addition, women who eating keto or low carb are encouraged to up their carbs in the luteal phase. Specifically foods high in zinc and vit C (think orange veggies like squash and sweet potato).
However, for the first half of a woman's cycle, the new research suggests that daily fasts of 16-18 hrs do not negatively impact hormones.
Research now suggests that if women follow this modified IF approach, not only do they not end up with negative effects on estrogen, progesterone, cortisol, etc but it actually balances hormones in cases of estrogen or progesterone dominance. It can also have a very beneficial effect in reducing perimenopause and menopause symptoms. Mainly because a major component of significant menopause symptoms is insulin resistance. Insulin resistance is also a culprit in PCOS.
Fix your insulin resistance ➡️ fix your sex hormones ➡️ fix your period woes.
I wish that this video had spent more time looking at what is now the accepted safe fasting protocol for women.
I can put this on my list to discuss in another video about this topic!
Great video Abbey. Lots of information to take away from this one. I often get asked a lot about ideal meal frequency for weight loss. Would it be fair to summarise from what you have said that as we get closer to or further beyond a total energy deficit, meal frequency becomes of greater importance for this demographic? In particular for those following Low of Very Low Energy Diets (which I would not recommend unless supervised for many of the reasons you have mentioned in your video).
I'm absolute in agreement about the risks, but you can actually turn bone density around after the age of 30! While the best is to build up the bones before 25, it isn't impossible to get better bones later.
Sinake et al in Bone 2002, Kelly et al in BMC Musculokelet Disorders 2012, and Kohrt et al in J Bone Miner Res 1997 all found improvements in bone mineral density and decreased risk of fractures with exercises(strength training over long periods of time), even in post-menopausal women! There is hope!
Thank you for that information, I will definitely have a look at that!
Thank you! This really made sense to me. Once I tried IF and got bloated and puffy in a way that I otherwise only experience on the first day of my period. Felt all around miserable. Because of all the ravings about IF I thought someting else was wrong, though. But after ten days (never made it until my period) I crashed completely and had an abysmal day of eating: multiple helpings of cake, ice cream, wine and cocktails - things that usually make me puffy. (It was fun, though.) Next day, the bloating and puffiness were gone. I'm not a nutritionist and haven't got a clue what was happening, but hormonal imbalances do fit the bill. I'm not trying IF ever again. One size does not fit all.
Did you not eat cake/ice cream etc during IF?
@@melima_ I did, but not in that quantity. :) I personally think that the eating window stressed me somehow. Breakfast, lunch and dinner at regular intervals works fine for me. No huge portions, not too much sugar or alcohol. No overthinking, since it only makes my hunger worse.
I'm so sorry for your negative experience. Absolutely!
@@AbbeysKitchen Oh thank you! :) After my binge-day I got back on track, so no real harm done. But it did make me wonder if I was the only one since everybody raved about IF. Your video is the first one to address any issues.
I did IF and low carb for 2 years - lost 25kg, my menstrual cycle, thinning hair, cold all the time. I’m still suffering the effects 2 years on as I am struggling with trying to conceive. I’m up 10kg which obviously is my set point but I do miss how great IF felt for my digestion. Obviously would reverse it all to not have these issues with infertility.
I’m so sorry for your experience!
Hi Madison, you may want to get your thyroid checked just to be on the safe side. I had the same problem and found out I have an under active thyroid. I’m glad I caught it early, just need to take a very low dose of levothyroxine in the morning and feel a lot better now.
Don’t want to scare you, but it’s a fairly common condition that’s often picked up late and is very easy to treat! Whatever the case may be, you feel better soon :)
I started ADF December 2021 and it has improved my life so much. Before i was constantly, hungry no matter what and how much I ate, and when I say "hungry" I mean I would puke from hunger, and that's while eating over 2500 kcal of good, healthy foods (I have a physical job ). I would walk around like a zombie from the moment I woke up to about 6pm. I felt constantly bloated, gassy and generally miserable. I have tried a lot of things but almost nothing has helped, when it did help it came with other problems and crazy restrictions.
On ADF I have managed to get my hunger hormones under control and now very rarely feels hungry, a LOT more and even energy throughout the day, no more stomach problems and NO food bans. Something I didn't expect to get out of it is that I now appreciate food much more than I did before, I now love trying new recipes and flavors. And my thoughts are no longer obsessively food oriented, when i think about food it's no longer backed by desperation, guild and shame. I have a much more healthy relationship with food and I love it.
ADF is not for everyone, it can trigger and give ED's, and like you said, if already lean you might lose to much.
In my case the pro's far, far outweigh the potential cons, for me it's an effortless lifestyle I'm planning on following for a very long time.
Lots of love from Sweden
Thanks for this information Abbey! I have lost 13kgs over the last year and a half. I didn't go about it in the best way to begin with, as it ended up in me losing my period for 200+ days. Blood tests showed that I was still producing enough hormones and not at risk for issues with bone density, but when I asked for a printed copy of my results, my hormones and vitals in general had taken a massive dip (I was told everything was ok). I introduced extra calories (putting me at maintenance) and incorporated more fat into my diet, but also, I started eating breakfast at 8am instead of 1pm, after a few months my period returned. I was very happy that I was able to do this without having to regain the weight I worked so hard to lose. I'm in a much healthier place now with food and exercise, I wish I had found a video like this before starting my journey, the world of weightloss is a very confusing one to navigate for many.
Thank you for sharing your experience with this! Glad you’re feeling better now 😊
Can you do a video on how to decide healthy portion sizes?
im a 39yr old mother of 2 and ive been IF for about 7yrs now. IF saved my life in so many ways ... not only did i lose all my baby weight after each kid but mentally it gives me a lot of clarity. I never had problems with my period and i was able to get pregnant without a problem both times. With that being said i make sure i take my vitamins i also make sure ii take enough sodium and i dont just eat pizza and fries. When it comes to IF or any other type of "lifestyle " it depends on the person ... everyone is different ... what works for me may not work for you. Im that person that cant be eating 5-6 meals a day that means i have to think about food all day and that to me is mentally draining. I rather have my 2 big healthy meals daily and not have my mind thinking of small meals all day. I do fasted cardio in the morning and lift after a meal. I would also like to add that when i started IF and lost weight is when i was finally able to get pregnant.
Yes same for me! I used to be so obsesed over every meal stressing what I am going to eat, how not to eat too much because even after eating breakfast I always ate big portion for lunch and then I was over eating…. I am such a wifie and preparing more that 2 meals per day for me and my bf would kill me. Can not even imagine to take care of two kids meal plan. 😄 Kudos to you!
Funny how our culture makes women think their lives have been "saved" by losing baby weight.
And of course, people who think they're so special that basic human physiology doesn't affect them.
Thank you for sharing what works for you!
@@itsgonnabeanaurfromme 👏🏽
@@itsgonnabeanaurfromme I mean, isn't losing baby weight good? People shouldn't be carrying excess weight anyways, so good for her that she lost it. Why is it a negative thing that she's proud of her weight loss? It's obviously good for her health lol
i did a 16 hour intermittent fast from sept to december and lost my period. got tested a month ago and turns out i got pcos from the restrictive diet :/ i've been working on eating more calories and protein now to regularize my hormones and period again.
edit - i forgot to say that i still do IF sometimes but i’m more conscious of my protein and calorie intake within my eating window
I’m so sorry for your experience. I hope you are starting to feel better!
same....
Feel like this is what’s happening to me. IF and also extreme stress lately… I’m forgetting my body isn’t as resilient as it was 10 years ago when I was 18
Women have to have a gene for PCOS... I am going to guess you were fasting to lose weight, right? Women with PCOS do tend to have a harder time losing weight. Acne, hair growth (chin, chest, etc), loss of hair (on your head), insulin resistance, etc. are all symptoms of PCOS. Women with PCOS can be deficient in certain vitamins and minerals. I have fasted for long periods of time. You can literally eat the same amount of calories, but just at a different time of day. Perhaps you should get tested to see if you are diabetic, insulin resistant, etc.
What test did you take to find that out?
My issue has always been that I don’t really get hungry until lunch time,I tried forcing myself to have breakfast for a while,even waiting a couple hours after I was awake to try and eat around 10/11 but it wasn’t terribly enjoyable and made me sorta nauseous and I ended up being just as hungry at my later meals and overeating,though it seems like Im around only 16 of so hours fasted so 🤞 that isn’t detrimental to me-I wouldn’t even know what is going on with my menstruation since I have an iud 😅
I understand, whatever works best for you!
I hope you find a balance that works for you! I’m 23 and still don’t get hungry until like 4pm. Exact same experience of trying to eat mechanically and getting nauseous
*disclaimer: I don’t consider my way of eating IF, just how I’m wired it seems
Same pinch, but I'm menopausal. If I eat breakfast I can't handle lunch. Three meals are just too much food for me. I have my tea, lunch by 12.30/1, fruit/nut snack in the late afternoon, and a light dinner.
Totally the same, it's so boring hearing people you barely know nag you about how breakfast is the most important meal of the day. Food should be enjoyed not make you feel dread, or sick. So long as you get everything you need in the hours you are eating, I see nbd. Eating 'perfectly' isn't as important as having a healthy relationship with food, and there is no perfect since everyone's body is different!
Love that you made this video, I wish I could've watched this 5 years ago when I was deep deep into my eating disorder. You do mention that adequate leptin production is very important for hormonal health and that adequate body fat levels are important for leptin production but you very much make it sound like not being underweight ("very lean") is the threshold for that (maybe I'm just reading that into it). I think there needs to be more awareness of the fact that for some people those body fat levels need to be much higher (for me about 30-32 percent before I could even bleed again, still don't ovulate every month after years of HA) and that dieting without affecting your hormone levels is not possible for some people even if they are only in a "small" deficit because they need a higher body fat percentage.
Still great that you tackled this topic, I hope it helps lots of people before they are as far down the rabbit hole as I was. Not having your hormones in check is exhausting and doctors are often so clueless as to what they're dealing with when it comes to hormonal and reproductive health.
Thank you for sharing! I’m glad you found the video helpful 😊
Following this advice could make it harder not to overeat. Having food in my face all day and only having a small meal is IMPOSSIBLE for me as a food addict. Snacks --- always lead to a binge.
If you intermittent fast and eat one large meal in the morning (if thats your thing) then you wont be in a energy deficit because you should be eating a large meal (1500 calories or more) to fuel yourself. Some people do that at night. Some people split it up into many meals.
You won't destroy your hormones if you eat enough to fuel yourself.
All of the studies she cites are based on underweight people and are NOT the average person trying to lose weight.
You can burn body fat as fuel if you fast so your body will only be in a deficit if you are underweight and starving or have high insulin. Fun fact: fasting reduces insulin.
The average obese person will have more than enough energy from fat stores to get through a few days or longer without any devastating effects besides fat loss.
This advice can be dangerous for severely obese people just looking for an excuse to keep eating all of the time to feel good.
Thanks for this comment! I was so confused when she used 400 calories as an example meal for IF. I naturally eat like this because I also like larger meals and I only seem to want them two times a day. No restriction whatsoever. It’s just what my body gravitates towards. 🤷🏼♀️
this is soo interesting! Could you talk more about low energy availability (LEA), relative energy deficiency (syndrome)? 1😍😍
Literally today in biology class our teacher made us watch a documentary that glorified intermittent fasting. It was rather triggering for me personally. This vid couldn't have come at a better time!
Share this with you biology teacher!
I don't see intermittent fasting too bad as long as it fits your lifestyle and you do it for the right reasons. I notice I got full quickly and for longer so it was easy for me to fast from 7 or 8pm to 11 in the morning. Usually not even hungry in the morning. But if one is uncomfortable and it's that much of a chore to do, don't do it! All I know is I feel much "lighter" going to bed as someone with acid reflux and waking up I feel good and progressively get hungry and have a great first meal of the day!
it's so weird that ur biology teacher is trying to teach you about diet 💀 like how is that relevant lmao unless maybe it's a nutrition class
Oh no 😫 I’m so sorry that was triggering for you!
@@luiysia the only thing you should be learning about in a nutrition class is diabetes/other chronic diseases, macronutrients and what foods are unhealthy
This is a very interesting topic, I actually read all the researches you cited in the destriction box, but those studies did not back the claims you made on this video. Most of the studies are not about fasting, but about caloric restriction or patients with anorexia nervosa. The few studies that are specific to fasting refer to very big periods of fasting, such as 72 days, which is definitely not common practice amongst those who do fasting.
I would really want to see more relevant and specific studies on the topic, because I have been thinking of trying 16:8 fasting myself. Not so much for weight loss, but mostly for the potential longevity benefits on several mammals and other animals. I found out about that after reading dr. Valter Longo's research and then I read dr. David Sinclair's book, which made some very interesting claims I would love to learn more about.
Thanks for reminding that amenorrea can cause low bone density.
I used to do intermitent fasting, working a lot (physical) and walking a lot and Il had amenorrea for 1 year and I had a stress neck femoral fracture, just walking by the street. I'm 28 and I may have an hip protesis. I Hope more women can be educated about the risks of IF and amenorrea !
Hey Abbey,
Why are you not filming in the kitchen anymore? I loved the setting 🥰
Sorry about that, I’m in between sets right now!
i love this video
Thanks!
I have been on 16/8 for years, the weight loss was not slow and then tried omad for weeks, the weight loss was even less. After learning about intuitive eating in your channel, I have adopted it for about 3 weeks now, my energy and mood are more stable and I noticed my clothes are looser. Thank you so much.
I’m so glad it’s been helpful for you, thank you for sharing! ❤️
I really appreciate all if your quality content Abbey! I was wondering what your thoughts are on the supplement Creatine? I hear it's helpful for muscle building but wanted to check if it's safe (as a 16 yr old girl) and if so, how much is safe?
IF was for me a trigger to binge eating. Now i eat mindfully and when i feel hungry and the binge has disapeared... it works for some people, but for one that had eating disorders (i was anorexic in my teens) it can be a trigger... for me was the case
It's a two thumbs down for me. I have done IF for over 3 years. It works. You just have to switch it up. I gained weight once I stopped working out, wfh, eating poor foods,, and not sticking to a good eating window. I am now back on track with ADF. Plus my slight ibs/constipation is cured. I appreciate that the visceral fat around my belly is becoming a thing of the past. My clothes fit better. My thoughts are clearer. And overall I am happier.
I can't begin to comprehend why your success story is threatened by this video and warrants a "two thumbs down" response. Abbey's thoughts are based on science and extensive research. Of course, Intermittent Fasting is effective, and people such as yourself see great weight loss results from it. However, there are definitely less apparent consequences from IF. As Abbey mentioned, IF is typically effective in aiding weight loss due to the simple fact that eating within a smaller time frame leads to a caloric deficit... and any diet that puts you in a caloric deficit will decrease your weight, potentially without the disruption to your metabolism, bone density loss, etc. All of this just to say that there are ways to safely lose weight and cure your IBS/constipation without subsequently causing other health issues.
A very informative video !!!!!!!love ur videos Abby 😊😊😊… Please do a video with the effect of IF on men ..Thank u ☺️☺️
I will put this on my list to discuss!
