I wish fasting was more mainstream. I don’t mention fasting to people because when I do they freak out. Fasting and low carb eating is the only thing that has ever worked for me.
I know. I just tell them I just ate. My son ate once a day the food his wife prepared for him. He drank herbal teas all day and ate at 1900. His boss loved him as he worked right thru lunch with high energy. His friends would try to sabotage his way of eating. But he was steadfast. His will power was powered by keeping his temple clean.
Absolutley. Fasting should be the default, as Dr. Fung says, not eating all day long. So we make it our default and do the best we can to change our environment.
@@dakotalynn7740 I had gestational diabetes during my last pregnancy and I was eating 3 meals a day on a schedule. I was not limiting the amount of food just no sugar and keeping my carbs under 100 grams per day and the diabetes coach freaked out and told me that if I didn’t eat more carbs, eat 4 snacks a day and take met Forman I was going to kill my baby…..I ignored her. I tracked my blood sugar. No need for met Forman. My son was born very healthy. Medical “professionals” don’t seem to understand food or how insulin works.
I am 190 I always been 145 my whole life at one point lower than that I've gained over 50 lbs in the last 4 years and now that I am engaged I am wanting more to be healthy again. czcams.com/users/postUgkx5VQ5nUzHu6i0O5_u7ipyLnCz0lbsSvr0 I am not fat but I am thick and have muscle. I am very close to how you were but a lil smaller but I am so sick people making comments to me like I'm huge or like you said having shorts that used to be so cute on me and now I can't even find a pair to fit me. I used to love shopping now I don't even want to go to the store and if I do I pick the biggest size don't even try it on and deal with it. I went from size 5 to size idk because I don't even want to know the real number. I hate looking at pics of myself now or me before. thank you for your video it's time to make a change.
My brother didn’t believe me when I spoke to him about fasting. He had to lose weight because of his back problems as per his Neurosurgeon. He was still stuck on the “5 small meals a day” ideology, but then I told him just try it and if you can’t resist, just stop. I made him watch Dr Fung’s videos. He tried it for 2 months and lost 50 pounds.
@@jay_wright_thats_right Eating more often (expanding the feeding window) keeps your insulin higher longer (even for small meals or snacks), which negates the idea of metabolic benefits. In essence you would be eating to burn more calories faster, but it doesn't work that way.

I caught a pattern of myself ordering doordash whenever I thought I couldn't think of anything else to think through; it's like an anxious, boredom 😐 plus I like using my hands, too. So I had to ween myself off and now I eat salmon six times a week and burger mixed,, organ meat 🍖 I have a 16/8 eating time so if I catch myself craving, it's pretty brief.
But when we eat for emotions we don’t choose monotonous foods. We choose the unhealthy carbs. We don’t choose the broccoli or a sandwich. So if the food we had to choose from was just the everyday veg etc we likely wouldn’t eat for emotional reasons either🤔🤷♀️
just finished my first 48 hr. fast, feel great. lost 45 lbs and counting in 3 mos. resting b.p. is 116/66 and heart rate of 62, blood sugar running 84-98 during the fast. never thought i would be a groupie but Dr. Fung, you sir rock!!! started out at 246 lbs now ticking 199 and dropping. doing omad 3-4 times a week, then reg 2mad no particular times, no calories counted. all white stuff removed from diet. minimal sugar....i love watermelon peace everyone
Unfortunately I have gastritis and my stomach burns without food and I can taste my stomach acid. Any advice for me to work around this, I need to loose weight
@@flaman1967 oh good all those seeds scare me. Personally, I just fast whenever my body says it's not hungry. As I started overweight, there's quite a lot there to go through
I grew up in the 1960’s. Every day I ate 1 egg, toast and milk for breakfast; 1 ham sandwich, an apple, 2 cookies and 250 ml. of chocolate milk for lunch; rice, stir-fried vegetables, a meat or fish dish, and milk for dinner. Yes, you are right, Dr. Fung, meals were not very exciting. We ate until satiated and no more. I was petite and slim until my 40’s. I had by then, started the high carb low fat diet recommended by the Food Pyramid. By the time I was in my 50’s I had developed pre-diabetes which I tried to reverse with the low carb high fat diet. I am okay as long as I restrict carbs. My experience with official medical/dietary recommendations have left me very skeptical. Thank you, Dr. Fung, for educating us.
Only eating what you prepare. I eat basically vegetables and meat. I cook one day, freeze/refrigerate enough for 5-6 days. My meals are tasty and enjoyable so i don't have the urge to buy any food or eat processed foods.
I love I.F. I find it's soooo much easier to just not eat than to open the fridge door and say "Ok, what can i eat not too much of?" It's so easy to simply get busy and not think of food at all. Or I'll have a cup of tea or coffee. I often say "I'll just do such & such first before I eat" (rake the leaves, take a bike ride). And before I know it I've forgotten about food altogether. Love this doc and Dr Valter Longo too.
Great teaching lesson! I've gone to the IF, for several months and have lost almost 60 pounds, so far. Not too bad for starting at 75 year old, 5'7'' and weighting 255 pounds (out of shape senior)! Side effects - having to buy all new slimmer clothes!! But I LOVE it! Thanks for your wisdom!
@@msmarygardner Oh, I absolutely agree. I haven't bought much of anything. I have plenty of slim clothes in my old clothes wardrobe that I "shop" from. I've even borrowed some shorts from my husband that I gave back when even they became too small. Removing my large sizes from the house was a chore, and somewhat emotional but now if feels great to have only clothes that fit me in my main closet and some smaller ones stored to "shop from" another day. Congratulations on your weight loss. Continued good health to you!!!
Azalea진달래 …yes, when I bought a few new clothes, (Walmart jeans etc) I thought I was done. Then when I lost a little more, it surprised me. It took the girl in a clothing store to convince me that I was a size 6. I was in denial & still bought a size 8, only to return them for a 6. (lol) It is an adjustment to accept the size. It’s a positive, good thing. 🤗 Congrats to you as well…it’s a way of life to enjoy food like we should!!
Dr. Fung has changed...and saved...so many lives! Thank you, good doctor, for making this information so readily available. Much appreciation and respect to you!
Switched to low carb diet and doing 18:6 fasting with occasional (1-2 times a week) OMAD and dropped 50 pounds. Blood test results are best they ever have been. My doctor said I was his only patient that lost weight during pandemic.
Fasting has changed my life! Imagine if everyone (adults) just ate once a day. It would solve so many of the world's problems! Everyone would be healthier and smarter😆. Many thanks to Dr. Fung for teaching me how to lose over 105 lbs so far! I'm happy about the variety I can still enjoy with my low carb high fat way of eating 😊
Eating once a day is very dificult for people who work hard, physical jobs. It might actually lead to undernourishment. If you are sedentary though, or a working a 9-to-5 desk job, that is something to consider.
@@josephfogus6735 1 meal a day just isn't realistic for people who are doing a lot of physical labor unless you stuff you face full but then that could lead to digestive problems.. Two meals a day is more reasonable.
@@only_6486 OMAD doesn’t have to be at one sitting, it can be at more than one but the goal is to have the fasting period of zero calories as long as you can, say 18 fast 6 eat, 18/6. If you can go 20/ 4, all the better. It doesn’t matter how much physical work you do. That’s a myth. If you have excess weight, your body will convert fat to the equal of food. It doesn’t matter if it comes thru ones mouth or off ones fatty acid stores. This will occur after you become fat adapted and will not be hungry or have cravings or hunger pains, ever again. Most certainly can’t stay on a high carb diet, have to lower carbs to more protein and fat, otherwise the hunger pains will persist.
@@only_6486 I guess everybody's body is different and more or less physical work for their jobs. I do one meal a day for dinner. I'm in the asphalt paving business, I stand 8-10+ hours a day, I physically work with a shovel, pick axe, broom, loop, tamp, etc I didn't think I would be able to do it at first, I only wanted to eat dinner. I eased into it by eating something small to coat my stomach in the morning like a fruit cup or half a sandwich. I think it took about 4 days to really get out of that feeling that I needed food to do all this physical work. But now it's no problem. I only drink water or unsweet tea in the morning and through the day. I don't really get hungry until later in the day when it's close to dinner time. But yeah, I don't know what your job is but it's probably more physical than mine but we should all do what we feel comfortable with, either way we are dieting I guess so whatever works best for us. Good luck to everybody, I wish I would have done this years ago when I was younger.
This is true. In Economics it is called marginal utility:the more you eat something then the pleasure diminishes. When I was a kid growing up I never ate out. I didn’t start eating out until fast food restaurants became ubiquitous. Also it was quick to walk in to get a burger and fries as opposed to buying chopped meat, fries, cheese and buns and then go home to cook it all. Now you have apps on your phone that allow you to sit at home or work and order a meal with ease! It is incredible. Intermittent fasting ABSOLUTELY works! Once you start it you won’t go back. I feel amazing, am losing weight and my blood pressure has decreased. I highly recommend it.

As someone who actually did the grocery shopping in the 70s, in Canada, we didn't have 3 aisles of very cheap pop and chips and cookies of every sort. Those things were expensive. We did however eat lots of different ethnic foods. Maybe Montreal was different but I was cooking French, Dutch, Chinese, Greek and Italian foods. I was also baking and the recipes did not include a cup of sugar for 12 muffins.
The older recipes had way less sugar, we use that as a guide and just cut the sugar to a couple of tablespoons. So far it works in everything we bake. At least cut the amount in half. 🌈
Love your work, Dr. Fung! I just ordered one of your books, "The Obesity Code." I am on a LCHF diet and have lost 37 lbs. I have about 43 lbs. to go. Thanks for the videos!
I took the Obesity Code with me to my doctors appointment, thinking I would have to argue with her about fasting. She had read it and we had a great discussion. Lost 15 pounds this year. Not as much as I wanted, but moving in the right direction.
I think the third factor is the big one. When I was a kid, I rushed off the school without first eating breakfast, and I ate something like a sandwich and an orange. I left school and played until it was dark or until my parents told me to eat. Basically, I did 2MAD, and in the afternoon, I burned off any glycogen I may have had in my system.
@@anonymousanonymous7304 Exercise is certainly good for you, and aside from weight loss, it can help with strength, endurance and appearance. I get cardio every say and resistance training two or three times a week. I should really be doing HIIT, too.
Fortunately, my gut can’t handle most of the food out there for some reason so I’m stuck to eating meat, eggs, and butter. I’m not bummed though because I feel much better and I’m losing weight.
When you reach your weight loss goals, you might consider eating small amounts of probiotic foods, like yogurt, kombucha, or kimchi. That might help you tolerate a wider variety of foods, but it will take time.
@@Me-xoxoz People can live on an all meat diet just fine, up to a point, but there's no long-lived populations that eat such a diet. Even Inuit and Yupik now days have greenhouses to grow vegetables.

This is such a hugely important topic. We have become a culture of food entertainment with nearly infinite novelty. It’s truly one of the key reasons for the obesity epidemic. Plus the amount of processed foods and the snacking culture.

As a diabetic I got the eat all the time advise. Junked it, now eating as I used to eat back in the day, three meals…eat to live, not live to eat. Amazing, my body is doing better
When you have no choice, you are forced to adapt. However, these days junk foods and snacks are everywhere. So people are eating all the time, the wrong foods on all occasions and no longer work as physically.
Yre far more genius ! It’s not that no one knows all these things but how well u make us realise the reality … realisation and acceptance is foremost to start maintains a healthy life. Love ya.. thanks for all the support I get from watching yr vdos !
I am following these three rules for the past eight months and have good weight and health now. I eat two times a day and have avoided snacking and very high carb foods. Lost 45 pounds. Blood pressure, blood glucose, cholesterol and triglycerides all are in the normal range now. I eat almost every thing I like but after eating, I give my body at least three hours to process what I ate and this makes the glucose to come to base level again. I also walk 30 minutes a day which helps a lot in digestion.
The only one that's really too good to be true is fasting from 36-86 hours at a time, but it really works and won't slow metabolism! Some of the many benefits of fasting and low carb diet on the immune system, blood pressure, blood sugar and anti-aging, all backed up by clinical data: Thymus stem cells are regenerated, which suppresses aging and renews the immune system. Fasting stimulates phagocytosis, the ingestion of bacteria and viruses by the immune system. Blood pressure is quickly and dramatically lowered, which is very important for a good outcome with the current pandemic. Fasting increases nitric oxide, which has manifold postive effects like reducing arterial plaque. Weght loss from fasting only loses10% lean tissue and 90% fat compared to the typical 25% lean tissue and 75% fat lost when calorically restricting for long periods. Blood clotting is reduced and blood clots and arterial plaque are reabsorbed into the body. Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy! Blood sugar and insulin are lowered, allowing white blood cells to move more freely throughout the body and do their job. Ideal blood sugar is around 80. Some viruses activate glycolosis (the release of sugar in the body) and clinically it has been shown that decreasing glucose metabolism in the body weakens the influenza virus. The hormone Leptin is an immunomodulator that keeps the body from attacking itself and obesity causes leptin resistance. Fasting very quickly reduces leptin resistance and leptin levels and one day of fasting can cut your leptin levels in half and gets your immune system working properly again! When you move out of MTOR your body shuts down the building blocks of the cell which are used to produce organelles and proteins. This means the mechanisms needed by viruses to replicate are by and large unavailable when you are in a deeply fasted state. It stimulates the AMPK complex and activates autophagy. Autophagy (literally self eating) will cause cells to recycle foreign matter such as viruses and kill cancerous and senescent cells. AMPK does many helpful things in the body including activating the body's antioxidant defenses. Deep ketosis virtually eliminates chronic inflammation in the body. This can offset the life threatening symptoms of viral pneumonia which effectively kills you through inflammation. This also creates BHB ketones in your body, which also help your immune system and anti-oxidative system, especially in the brain. Ketones also provide an additional energy source during infection, which is critical when trying to fight off a bug. In fact you can have as much as three times the total energy available in your blood when you are in deep ketosis, or even more. It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency and thereby making cells better able to fight off infection. Increased mitochondrial function also has the added benefit of increasing your metabolism and cancer prevention! Your body releases interferon which is also triggered by the body during viral attacks to shut down the replication ability of the surrounding cells and stop infections. After 72 hours or more fasted, your body actually recycles large numbers of immune bodies and creates new ones, rejuvenating your entire system. When you fast, this stimulates apoptosis in senescent or genetically damaged cells. This kills these cells off completely. Senescent cells are responsible for the effects of aging and are the root cause of the development of cancer. If it were possible to destroy them all it would completely stop aging and cancer. That is not possible but fasting can help limit these effects by killing off many of the affected cells and limiting the future effects of aging. Fasting also releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth, helping a great deal with diseases like MS, peripheral neuropathy and Alzheimers. In fact, the biochemical precursor to BDNF is beta-hydroxybutyrate, which is the same ketone the body produces to nourish the brain while fasting. Dieters losing weight through intermittent fasting show greater reduction in waist size and increase in insulin sensitivity for the same weight lost and alternate day fasters were shown to lose fat while gaining muscle at the same time over a six month period. Fasting has been shown to increase bone marrow volume by 10% and levels of carnosine in the body in as little as a few weeks. Fasting also increases telomere length, negating some of the effects of aging at a cellular level. Eating one meal a day can bring most of these benefits to a lesser degree, and adding a few entire days off from eating per week will have even more effect especially when starting to feel poorly. Exogenous ketones can aid with fasting, making it easier in healthy people and allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia. Children, pregnant or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors or hypoglycemia generally cannot fast at all. Type 1 diabetics can also fast but it is more complicated and should be approached with caution. Those with Addison's disease may also be unable to fast without liberal use of exogenous ketones, depending on severity. If you experience extreme symptoms of some kind, especially dizziness then simply break the fast and seek advice.

@@jacksonposhee4687 I don't fast for weight loss as a main goal, but my weight loss has stopped for awhile even when doing 36 hour fasts three times a week. If I mix it up and do a longer fast the scale goes down again. Interestingly, another time, I spent two weeks not doing as much fasting as I normally do and suddenly the scale started to go down again. Maybe mixing it up is the key. But generally I'd say do a few longer fasts if body fat loss is your goal and things aren't moving like you want. And be sure to eat well when you do eat.
@@AzaleaBee You are probably juste ating more. Usually when people do ADF they eat a bit more but still wind up with weight loss. You will especially eat more if you are leaner, it is your body controlling your hunger properly. When you need to lose weight it will be much less, if any, so long as you keep carbs down.
@@LTPottenger Actually although that might be a possible explanation for other times/ other people, I was not eating more or anything different. I've been doing ADF regularly for several months now as keeping my blood sugar low ... generally belwo 73.. is my main goal.
Very Interesting Dr Fung ... As a teen in the 70s I ate a bologna and relish sandwich, including the weekends, everyday for 6 years so your point really hit home for me . Thank you for your videos they have been very helpful

People who are obese can find the ultimate solution in fasting, especially alternate day fasting (ADF). They can demonstrate to all the "you don't have the will power" bigots just how much will power they have. In my opinion, based on experience, ADF is very effective. You can eat almost what you want every other day and do not have to fret about calories. Of course, eating too much sugar and cake is not going to do you any good. The 36+ hours of fasting results in the shrinkage of the stomach so that you eat less on the eating day. Overall, the calorie intake drops by 60% or more depending on what the previous intake was. There is no desire to gorge on the eating day. There is some mild hunger, especially at the outset of this program, but it is manageable. Also, do aerobic exercise on the fasting days, it will help burn through the fat stores faster. The lie that the metabolism slows down without regular eating has destroyed the health of tens of millions. This lie needs to be exposed and this channel is doing a stellar service.
I’m experiencing fantastic results myself with ADF and agree. I’ve gotten results on carbs too but there’s nothing like whole foods keto + ADF for torching belly fat
I literally was told that my restrictive eating is causing me to not lose weight...From a dietician!!! I'm a total thyroidectomy survivor (2010)..I was diagnosed with breast cancer January 2020 and put on Tamoxifen after lumpectomy and radiation. These a$$holes want to look at my weight gain and not my total weight loss. My original weightloss from Keto and Intermittent fasting is 112 pounds. Then I gained 55 pounds since being on Tamoxifen... In one year... Tamoxifen also DESTROYED my uterus in that time frame. So.... I became stricter with my eating...Now I have 35 pounds to get back to that 112 pound loss. I'm losing the weight..Just slower...But I'm doing it.... and when I started eating two meals a day per my dietitian... I gained 8 pounds in two days..Which told me I was inflamed. It came off in three days with fasting. I'm going to continue following Dr.Fung and doing what has helped me BEFORE cancer... My doctors are not my friends.
@@novasimmons3828 Sorry to hear about your situation, but fully support you in ignoring the frauds (dieticians and even the non-specialist doctors who are unqualified to give any diet advice) and persevering in your objectives. Fasting is essential for reduction of cancer risk and for getting over cancer as Dr. Fung and others have effectively related in their videos. We have all of this cellular repair machinery (autophagy) but it is turned off because of sustained elevated insulin levels. After learning how industrial seed oils (aka vegetable oils) damage mitochondria and how mitochondrial function is related to cancer, I will never trust these medical "experts" again. We are simply not informed on the relevant science by the MSM and most people are not going to wade through the research literature to get the information. Fasting helps detox from omega-6 oils. Thanks to vegetable oils we now have people with nearly 20:1 omega-6 to omega-3 ratios when they should not be any more than 1:1.
@@johnsmith-fr3sx Thank you. I agree 100%. The biggest thing for me is the cancer. How is Tamoxifen suppose to prevent me from getting cancer recurrence by controlling my estrogen production if it's causing me weight gain? Estrogen is produced in fatty cells. And having these idiots tell me to eat more because they are "certified?" Nope. I'm with you. I'll never trust the "experts," in clinics.
Today was my first day of IF . I am so happy I came across these videos with Dr. Fung he has such helpful tips and all of it makes so much sense. I want to loose 20lbs I’m getting married in June so I hope I can loose this weight and just completely make this a whole life style change for me. I know there is different ways to do IF I was going to start off and try to do the 5:2 method. If anyone has any advice I would appreciate it. Thank you!
as I watch this video what I contemplate is how much physical weight I have to release: (75.2 Lbs to be precisely exact!) for the sake of my health and for my well-being. the thing is though... I realize that I desperately also hold on to all the excess weight: for safety and for comfort. dear God, please please please, help the weight dissolve off of me, and please help me to no longer have the need to hold on to any of it, for the illusion of safety and protection. I am ready to be permanently, forever released from these shackles...
This makes sense. The last restrictive diet I followed was keto. At first it was great. Then good. Then boring. Then gross. I was so sick of the foods after 6 months. I craved bread and starchy vegetables. When I got a horrible keto rash on my face, shoulders, back, and torso, I finally caved and ate potatoes and beans. The week long rash began to clear in just hours. I quit all dieting, resigned to just getting old and fat -- until IF. Now I feel amazing. No more bloating, no yo-yo-ing weight gains, no afternoon energy crashes, and best of all, no restricted foods. I crave wholesome, whole, nutrient dense foods most of the time, but I can also indulge in the occasional donut at the end of my window when I'm close to full (I never want a second one anymore). We just spent three weeks in Quebec eating all of the pastries (I just followed an easy 12:12 window most days), and it only took a week of going back to my normal IF pattern (20:4 is my favorite) to drop the vacation bloat. I was about 135 lbs when we left, about 140 when we got home, and I was down to 130 with no special effort. Maybe I'll even see 125 again someday (I'm 54, and that was my high school weight). And if not, who cares? I'm so grateful for this. Simple, sustainable, and free. No plans, no special foods. And I just move my window up or down to accommodate family gatherings or special occasions (and I'm just gonna continue to have long windows on vacations and eat ALL the yummy foods). This is living. Just wish I had known about this 30 years ago.
What I love about Dr. Fung is his simple and low key, no frills style. Its easy to understand and even easier to follow and IT WORKS!! His advice needs to reach more people And for that I feel he needs to work on his video thumbnail. Thank you.
@@anitas5817 I agree. I mean seeing the not so pleased comments, I thought about it again. But... I love the playfulness!🙃 It makes me think of the kind and caring things Dr. Fung has said in some interviews.
I don't touch food from around 11 pm- 3am,to about 8-9 pm the next day, just MCT oil in my morning coffee, and heavy cream in my late afternoon coffee, I've been doing this over a year now, but been on keto 2 1/2 years, I don't even get hungry outside of my eating window once your body gets used to eating a ceratin way, and certain times, it becomes very easy to do.
I am definitely sharing it ! It's so genuine and honest. And it cleared my greatest doubt..to the point of saying 'aa huh so that was the reason'. Regards from another doctor from India 🙏
I've had severe health anxiety ever since I went into hospital for High Blood Pressure.I am obese and I started doing 24 to 48 hours fasting weekly depending on my mode. I go to the gym 5 days a week and I have lost 39 lbs(18kg) in about 2 and the half months. People are asking me if I am sick and it is depressing me and making my health anxiety worst with the feeling something is wrong and that's why i am losing much weight at a fast pace even thou i know I am putting in the work. I am still obese and want to lost more weight but the comments I am getting about being sick is discouraging me to continue and making my anxiety worst,when it was getting better.
I finally got to understand the whatness and howness of "food intakes" when I started watching the informative videos of Dr. Fung...thanks Dr🤗 I hope you can come up with a more detailed video about why the "plateauing" of weight somewhere along the fasting process happens..
I am from sri lanka following your diet fasting lost 4 kgwithing 4 month.No any illness .But i have to lost 6 kg to maintain my healthy lifestyle . Thankyou for your great advice doctor. ❤️🙏🙏
Variety in eating back 50 or 60 years ago was having a different entrée on the dining table for dinner. Today, variety is heading to a different fast food joint for dinner.
A balance of the same staple foods with some variety for pleasure is important. In our particularly convenient food rich toxic environment we have to be even more diligent to plan and prep for successful meals/ fasting.
Jason, thanks again for your wisdom on these matters; I cannot thank you enough for setting the record straight for me. This system has worked out great for me thus far, however, as you stated we are all different and some things I may have overdone, but overall it is the answer. I have some tweaking to work on.
Also in the late 70's the microwave oven came along to most people's homes, making it super easy and convenient to heat up foods that were mostly processed foods created for the microwave meals market; making people even more obese.
I thing that I can share based on my personal experience is that fasting TREMENDOUSLY improves the symptoms of PCOS and can cure infertility…after suffering through infertility for 15 years , multiple failed IVF cycles, years of fertility drugs…I almost gave up, then I watched a video by a fertility doctor who recommended Dr Fung’s fasting regime for improving fertility…at age 38 I became pregnant naturally after fasting for 3 months ..I had my daughter and then again at age 40 I had conceived my son after again fasting for about 3 months….it changed my hormones which then regulated my reproductive system….I CANNOT recommend enough how powerful fasting is for fertility
Everybody's told to eat slowly and chew properly their food, partly because it does help to kick in the satiety signal sooner, so you don't over eat. I can testify to that because I've always been a slow eater and as a result I have a very small stomach that simply can not handle the amounts of food I see everyone else eat in one sitting, I would be literally sick if I tried to do that. Now, however, I am told that to get my insulin down I should be having just one meal a day, or two at the most. I understand the reasons very well, but I simply can't do this - I know, I've tried. I became malnourished because I have to continue to eat child-size portions and if I can only eat once or twice a day I simply don't get enough calories or nutrients to be able to function normally. I get very weak and listless and even my voice starts to fade. So I need to eat three, sometimes four times a day just to get enough food to sustain me. I eat clean, but I can't shed the weight unless I fast to lose the excess I have gained during feeding days, in an endless cycle. It's ironic that those who disregarded the so-called good advice and gorge themselves on food at every meal and have stretched out, over enlarged stomachs can do the OMAD life style, whereas someone with insulin resistance like me can't benefit from it because I did the right thing all my life. Just saying.
It also helps breaking down nutrients. If you don't chew your food properly until liquified it will be much harder for your digestive system to process. This is especially true for vegetable matters. But we are all in a hurry these days, and most of us have become fast, unconcious eaters.
@@RedErin I'm a carnivore, as most vegetables make me sick. This is true of people like me who have leaky gut. Also, I've noticed that people are always told to listen to their body... until their body tells them something that contradicts dogma. Then their body is wrong, and the fact that you're fat and sick is entered as proof that you can't trust yourself or your body...
Eat whole foods and avoid processed foods as much as possible. Organic veggies if you can afford it. Grass fed, steroid free beef if you can afford it. Healthy food is expensive, but cheap processed food will kill you.
One of the main root causes of allergies and autoimmune diseases such as Hashimoto's is a leaky gut. Even aging is affected by a leaky gut as your immune system squanders precious NAD fighting infiltration of bacteria into the blood stream. This can be corrected with a combination of 72+ hour fasts, avoiding lectins, sugar, bread and pasta and supplementation with gut healthy foods.

I have never heard anyone say it so simply and clearly. Diets succeed and fail for the same reason: monotony. From a lifetime of observation, I would say that is correct.

I wish fasting was more mainstream. I don’t mention fasting to people because when I do they freak out. Fasting and low carb eating is the only thing that has ever worked for me.
I know. I just tell them I just ate.
My son ate once a day the food his wife prepared for him.
He drank herbal teas all day and ate at 1900. His boss loved him as he worked right thru lunch with high energy.
His friends would try to sabotage his way of eating. But he was steadfast. His will power was powered by keeping his temple clean.
Bejing Biden will bring in prolonged fasting for the entire country.
@@chaz6399 it’s already happening.
Absolutley. Fasting should be the default, as Dr. Fung says, not eating all day long. So we make it our default and do the best we can to change our environment.
@@dakotalynn7740 I had gestational diabetes during my last pregnancy and I was eating 3 meals a day on a schedule.

My brother didn’t believe me when I spoke to him about fasting. He had to lose weight because of his back problems as per his Neurosurgeon. He was still stuck on the “5 small meals a day” ideology, but then I told him just try it and if you can’t resist, just stop. I made him watch Dr Fung’s videos. He tried it for 2 months and lost 50 pounds.
@@jay_wright_thats_right Eating more often (expanding the feeding window) keeps your insulin higher longer (even for small meals or snacks), which negates the idea of metabolic benefits. In essence you would be eating to burn more calories faster, but it doesn't work that way.

I would suggest that there is a third reason people eat: comfort/stress. Pretty powerful motivators.
Cortisol spikes sugar and insulin and this is why avoiding high carb is very important under stress conditions. It makes things much worse.
Absolutely, spot on!
I caught a pattern of myself ordering doordash whenever I thought I couldn't think of anything else to think through; it's like an anxious, boredom 😐 plus I like using my hands, too. So I had to ween myself off and now I eat salmon six times a week and burger mixed,, organ meat 🍖 I have a 16/8 eating time so if I catch myself craving, it's pretty brief.
But when we eat for emotions we don’t choose monotonous foods. We choose the unhealthy carbs. We don’t choose the broccoli or a sandwich. So if the food we had to choose from was just the everyday veg etc we likely wouldn’t eat for emotional reasons either🤔🤷♀️

230 pounds is roughly 2.5 super models - that's incredible!
Congrats Chris Owen!
@@flaman1967 oh good all those seeds scare me.
Personally, I just fast whenever my body says it's not hungry. As I started overweight, there's quite a lot there to go through
I grew up in the 1960’s. Every day I ate 1 egg, toast and milk for breakfast; 1 ham sandwich, an apple, 2 cookies and 250 ml. of chocolate milk for lunch; rice, stir-fried vegetables, a meat or fish dish, and milk for dinner. Yes, you are right, Dr. Fung, meals were not very exciting. We ate until satiated and no more. I was petite and slim until my 40’s. I had by then, started the high carb low fat diet recommended by the Food Pyramid. By the time I was in my 50’s I had developed pre-diabetes which I tried to reverse with the low carb high fat diet. I am okay as long as I restrict carbs. My experience with official medical/dietary recommendations have left me very skeptical. Thank you, Dr. Fung, for educating us.
Ham sandwiches cookies and toast are in Dr Fung meals?
Only eating what you prepare. I eat basically vegetables and meat. I cook one day, freeze/refrigerate enough for 5-6 days. My meals are tasty and enjoyable so i don't have the urge to buy any food or eat processed foods.
I agree! Only homemade foods for me also. You have to plan ahead and take a little time but healthy meals don't have to be fancy....👍
I was on a diet last week it was the worst 5 minutes of my life .
I love I.F. I find it's soooo much easier to just not eat than to open the fridge door and say "Ok, what can i eat not too much of?" It's so easy to simply get busy and not think of food at all. Or I'll have a cup of tea or coffee. I often say "I'll just do such & such first before I eat" (rake the leaves, take a bike ride). And before I know it I've forgotten about food altogether. Love this doc and Dr Valter Longo too.
Great teaching lesson! I've gone to the IF, for several months and have lost almost 60 pounds, so far. Not too bad for starting at 75 year old, 5'7'' and weighting 255 pounds (out of shape senior)! Side effects - having to buy all new slimmer clothes!! But I LOVE it! Thanks for your wisdom!
Nice to hear, Tai Chi Man. On to better health and slimmer clothes!!!
Azalea진달래 …don’t buy too many new clothes lol. You may continue (to lose MORE weight) like I did & need even a smaller size 🤗
@@msmarygardner Oh, I absolutely agree. I haven't bought much of anything. I have plenty of slim clothes in my old clothes wardrobe that I "shop" from. I've even borrowed some shorts from my husband that I gave back when even they became too small.
Removing my large sizes from the house was a chore, and somewhat emotional but now if feels great to have only clothes that fit me in my main closet and some smaller ones stored to "shop from" another day.
Congratulations on your weight loss. Continued good health to you!!!
Azalea진달래 …yes, when I bought a few new clothes, (Walmart jeans etc) I thought I was done. Then when I lost a little more, it surprised me. It took the girl in a clothing store to convince me that I was a size 6. I was in denial & still bought a size 8, only to return them for a 6. (lol) It is an adjustment to accept the size. It’s a positive, good thing. 🤗 Congrats to you as well…it’s a way of life to enjoy food like we should!!
Mee too, thank God fir "Vintage" Clothing Stores!!!

Switched to low carb diet and doing 18:6 fasting with occasional (1-2 times a week) OMAD and dropped 50 pounds. Blood test results are best they ever have been. My doctor said I was his only patient that lost weight during pandemic.
Fasting has changed my life! Imagine if everyone (adults) just ate once a day. It would solve so many of the world's problems! Everyone would be healthier and smarter😆.
Many thanks to Dr. Fung for teaching me how to lose over 105 lbs so far! I'm happy about the variety I can still enjoy with my low carb high fat way of eating 😊
Eating once a day is very dificult for people who work hard, physical jobs. It might actually lead to undernourishment. If you are sedentary though, or a working a 9-to-5 desk job, that is something to consider.
I got a physical job so I eat 2 meals a day it's not bad. One meal might be tough every day.
@@josephfogus6735 1 meal a day just isn't realistic for people who are doing a lot of physical labor unless you stuff you face full but then that could lead to digestive problems.. Two meals a day is more reasonable.
@@only_6486 OMAD doesn’t have to be at one sitting, it can be at more than one but the goal is to have the fasting period of zero calories as long as you can, say 18 fast 6 eat, 18/6. If you can go 20/ 4, all the better. It doesn’t matter how much physical work you do. That’s a myth. If you have excess weight, your body will convert fat to the equal of food. It doesn’t matter if it comes thru ones mouth or off ones fatty acid stores. This will occur after you become fat adapted and will not be hungry or have cravings or hunger pains, ever again. Most certainly can’t stay on a high carb diet, have to lower carbs to more protein and fat, otherwise the hunger pains will persist.
@@only_6486 I guess everybody's body is different and more or less physical work for their jobs. I do one meal a day for dinner.
I'm in the asphalt paving business, I stand 8-10+ hours a day, I physically work with a shovel, pick axe, broom, loop, tamp, etc I didn't think I would be able to do it at first, I only wanted to eat dinner.
I eased into it by eating something small to coat my stomach in the morning like a fruit cup or half a sandwich.
I think it took about 4 days to really get out of that feeling that I needed food to do all this physical work. But now it's no problem. I only drink water or unsweet tea in the morning and through the day. I don't really get hungry until later in the day when it's close to dinner time.
But yeah, I don't know what your job is but it's probably more physical than mine but we should all do what we feel comfortable with, either way we are dieting I guess so whatever works best for us. Good luck to everybody, I wish I would have done this years ago when I was younger.
This is true. In Economics it is called marginal utility:the more you eat something then the pleasure diminishes. When I was a kid growing up I never ate out. I didn’t start eating out until fast food restaurants became ubiquitous. Also it was quick to walk in to get a burger and fries as opposed to buying chopped meat, fries, cheese and buns and then go home to cook it all. Now you have apps on your phone that allow you to sit at home or work and order a meal with ease! It is incredible.
Intermittent fasting ABSOLUTELY works! Once you start it you won’t go back. I feel amazing, am losing weight and my blood pressure has decreased. I highly recommend it.
My pre-diebetes has gone from fasting - it worked 🙂🙂🙂

As someone who actually did the grocery shopping in the 70s, in Canada, we didn't have 3 aisles of very cheap pop and chips and cookies of every sort. Those things were expensive.
We did however eat lots of different ethnic foods. Maybe Montreal was different but I was cooking French, Dutch, Chinese, Greek and Italian foods. I was also baking and the recipes did not include a cup of sugar for 12 muffins.
Now it’s a cup of sugar per muffin 😂
@@Yararar yes. My cook book by Madame Benoit said 2 tablespoons if you want a really sweet muffin lol.
A cup of flour is pretty much the same as a cup of sugar. Educate yourself on what carbohydrates are.
@@TheCuratorIsHere yes. But today's muffins then contain twice as much sugar. I was pointing out that my cookbooks had much less sugar in everything.
The older recipes had way less sugar, we use that as a guide and just cut the sugar to a couple of tablespoons. So far it works in everything we bake. At least cut the amount in half. 🌈
Love your work, Dr. Fung! I just ordered one of your books, "The Obesity Code." I am on a LCHF diet and have lost 37 lbs. I have about 43 lbs. to go. Thanks for the videos!

I think the third factor is the big one. When I was a kid, I rushed off the school without first eating breakfast, and I ate something like a sandwich and an orange.

This is such a hugely important topic. We have become a culture of food entertainment with nearly infinite novelty. It’s truly one of the key reasons for the obesity epidemic. Plus the amount of processed foods and the snacking culture.

Yes, it was not willpower. In the 1970s we had no choice to eat or not eat. Mother told us when mealtime was, and we were restricted to those times.

I am following these three rules for the past eight months and have good weight and health now. I eat two times a day and have avoided snacking and very high carb foods. Lost 45 pounds. Blood pressure, blood glucose, cholesterol and triglycerides all are in the normal range now. I eat almost every thing I like but after eating, I give my body at least three hours to process what I ate and this makes the glucose to come to base level again. I also walk 30 minutes a day which helps a lot in digestion.
So much insight. I have noticed having less different types of foods does indeed help.
This man is SO SO smart!
The only one that's really too good to be true is fasting from 36-86 hours at a time, but it really works and won't slow metabolism!
Some of the many benefits of fasting and low carb diet on the immune system, blood pressure, blood sugar and anti-aging, all backed up by clinical data:
Thymus stem cells are regenerated, which suppresses aging and renews the immune system.
Fasting stimulates phagocytosis, the ingestion of bacteria and viruses by the immune system.
Blood pressure is quickly and dramatically lowered, which is very important for a good outcome with the current pandemic.
Fasting increases nitric oxide, which has manifold postive effects like reducing arterial plaque.
Weght loss from fasting only loses10% lean tissue and 90% fat compared to the typical 25% lean tissue and 75% fat lost when calorically restricting for long periods.
Blood clotting is reduced and blood clots and arterial plaque are reabsorbed into the body.
Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy!
Blood sugar and insulin are lowered, allowing white blood cells to move more freely throughout the body and do their job. Ideal blood sugar is around 80. Some viruses activate glycolosis (the release of sugar in the body) and clinically it has been shown that decreasing glucose metabolism in the body weakens the influenza virus.
The hormone Leptin is an immunomodulator that keeps the body from attacking itself and obesity causes leptin resistance. Fasting very quickly reduces leptin resistance and leptin levels and one day of fasting can cut your leptin levels in half and gets your immune system working properly again!
When you move out of MTOR your body shuts down the building blocks of the cell which are used to produce organelles and proteins. This means the mechanisms needed by viruses to replicate are by and large unavailable when you are in a deeply fasted state.
It stimulates the AMPK complex and activates autophagy. Autophagy (literally self eating) will cause cells to recycle foreign matter such as viruses and kill cancerous and senescent cells. AMPK does many helpful things in the body including activating the body's antioxidant defenses.
Deep ketosis virtually eliminates chronic inflammation in the body. This can offset the life threatening symptoms of viral pneumonia which effectively kills you through inflammation. This also creates BHB ketones in your body, which also help your immune system and anti-oxidative system, especially in the brain. Ketones also provide an additional energy source during infection, which is critical when trying to fight off a bug. In fact you can have as much as three times the total energy available in your blood when you are in deep ketosis, or even more.
It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency and thereby making cells better able to fight off infection. Increased mitochondrial function also has the added benefit of increasing your metabolism and cancer prevention!
Your body releases interferon which is also triggered by the body during viral attacks to shut down the replication ability of the surrounding cells and stop infections.
After 72 hours or more fasted, your body actually recycles large numbers of immune bodies and creates new ones, rejuvenating your entire system.
When you fast, this stimulates apoptosis in senescent or genetically damaged cells. This kills these cells off completely. Senescent cells are responsible for the effects of aging and are the root cause of the development of cancer. If it were possible to destroy them all it would completely stop aging and cancer. That is not possible but fasting can help limit these effects by killing off many of the affected cells and limiting the future effects of aging.
Fasting also releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth, helping a great deal with diseases like MS, peripheral neuropathy and Alzheimers.
In fact, the biochemical precursor to BDNF is beta-hydroxybutyrate, which is the same ketone the body produces to nourish the brain while fasting.
Dieters losing weight through intermittent fasting show greater reduction in waist size and increase in insulin sensitivity for the same weight lost and alternate day fasters were shown to lose fat while gaining muscle at the same time over a six month period.
Fasting has been shown to increase bone marrow volume by 10% and levels of carnosine in the body in as little as a few weeks.
Fasting also increases telomere length, negating some of the effects of aging at a cellular level.
Eating one meal a day can bring most of these benefits to a lesser degree, and adding a few entire days off from eating per week will have even more effect especially when starting to feel poorly.
Exogenous ketones can aid with fasting, making it easier in healthy people and allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia.
Children, pregnant or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors or hypoglycemia generally cannot fast at all. Type 1 diabetics can also fast but it is more complicated and should be approached with caution. Those with Addison's disease may also be unable to fast without liberal use of exogenous ketones, depending on severity. If you experience extreme symptoms of some kind, especially dizziness then simply break the fast and seek advice.

there is no plataeu in 36 fasting?
@@jacksonposhee4687 No, you can do it for your whole life, which is called alternate day fasting.
@@jacksonposhee4687 I don't fast for weight loss as a main goal, but my weight loss has stopped for awhile even when doing 36 hour fasts three times a week. If I mix it up and do a longer fast the scale goes down again.
Interestingly, another time, I spent two weeks not doing as much fasting as I normally do and suddenly the scale started to go down again. Maybe mixing it up is the key. But generally I'd say do a few longer fasts if body fat loss is your goal and things aren't moving like you want. And be sure to eat well when you do eat.
@@AzaleaBee You are probably juste ating more. Usually when people do ADF they eat a bit more but still wind up with weight loss. You will especially eat more if you are leaner, it is your body controlling your hunger properly. When you need to lose weight it will be much less, if any, so long as you keep carbs down.
@@LTPottenger Actually although that might be a possible explanation for other times/ other people, I was not eating more or anything different. I've been doing ADF regularly for several months now as keeping my blood sugar low ... generally belwo 73.. is my main goal.
Very Interesting Dr Fung ... As a teen in the 70s I ate a bologna and relish sandwich, including the weekends, everyday for 6 years so your point really hit home for me . Thank you for your videos they have been very helpful
Deviled ham sandwiches on Wonderbread with a bag of Fritos corn chips ... a staple brown bag lunch of the 70's eaten because we were hungry and just looking forward to recess. :)
I remember bologna, mayo & tomato, lettuce sandwiches on white bread. Memories
@@AzaleaBee, oh yes, the deviled ham sandwiches with Kraft greasy sandwich spread. Lol
@@jgrysiak6566 You can still buy that sandwich spread at Walmart LOL
People who are obese can find the ultimate solution in fasting, especially alternate day fasting (ADF). They can demonstrate to all the "you don't have the will power" bigots just how much will power they have. In my opinion, based on experience, ADF is very effective. You can eat almost what you want every other day and do not have to fret about calories. Of course, eating too much sugar and cake is not going to do you any good. The 36+ hours of fasting results in the shrinkage of the stomach so that you eat less on the eating day. Overall, the calorie intake drops by 60% or more depending on what the previous intake was. There is no desire to gorge on the eating day. There is some mild hunger, especially at the outset of this program, but it is manageable. Also, do aerobic exercise on the fasting days, it will help burn through the fat stores faster. The lie that the metabolism slows down without regular eating has destroyed the health of tens of millions. This lie needs to be exposed and this channel is doing a stellar service.
I’m experiencing fantastic results myself with ADF and agree. I’ve gotten results on carbs too but there’s nothing like whole foods keto + ADF for torching belly fat
It works great! I did that for several months to good effect.
I literally was told that my restrictive eating is causing me to not lose weight...From a dietician!!!
I'm a total thyroidectomy survivor (2010)..I was diagnosed with breast cancer January 2020 and put on Tamoxifen after lumpectomy and radiation.
These a$$holes want to look at my weight gain and not my total weight loss.
My original weightloss from Keto and Intermittent fasting is 112 pounds. Then I gained 55 pounds since being on Tamoxifen... In one year... Tamoxifen also DESTROYED my uterus in that time frame.
So.... I became stricter with my eating...Now I have 35 pounds to get back to that 112 pound loss.
I'm losing the weight..Just slower...But I'm doing it.... and when I started eating two meals a day per my dietitian... I gained 8 pounds in two days..Which told me I was inflamed.
It came off in three days with fasting.
I'm going to continue following Dr.Fung and doing what has helped me BEFORE cancer...
My doctors are not my friends.
@@novasimmons3828 Sorry to hear about your situation, but fully support you in ignoring the frauds (dieticians and even the non-specialist doctors who are unqualified to give any diet advice) and persevering in your objectives. Fasting is essential for reduction of cancer risk and for getting over cancer as Dr. Fung and others have effectively related in their videos. We have all of this cellular repair machinery (autophagy) but it is turned off because of sustained elevated insulin levels. After learning how industrial seed oils (aka vegetable oils) damage mitochondria and how mitochondrial function is related to cancer, I will never trust these medical "experts" again. We are simply not informed on the relevant science by the MSM and most people are not going to wade through the research literature to get the information. Fasting helps detox from omega-6 oils. Thanks to vegetable oils we now have people with nearly 20:1 omega-6 to omega-3 ratios when they should not be any more than 1:1.
@@johnsmith-fr3sx Thank you. I agree 100%.
The biggest thing for me is the cancer. How is Tamoxifen suppose to prevent me from getting cancer recurrence by controlling my estrogen production if it's causing me weight gain? Estrogen is produced in fatty cells. And having these idiots tell me to eat more because they are "certified?"
Nope. I'm with you. I'll never trust the "experts," in clinics.
We're so lucky to have Dr Fung
Today was my first day of IF .
I am so happy I came across these videos with Dr. Fung he has such helpful tips and all of it makes so much sense. I want to loose 20lbs I’m getting married in June so I hope I can loose this weight and just completely make this a whole life style change for me. I know there is different ways to do IF
I was going to start off and try to do the 5:2 method. If anyone has any advice I would appreciate it. Thank you!
as I watch this video what I contemplate
is how much physical weight I have to release:
(75.2 Lbs to be precisely exact!)
for the sake of my health
and for my well-being.
the thing is though...
I realize that I desperately also
hold on to all the excess weight:
for safety and for comfort.
dear God, please please please,
help the weight dissolve off of me,
and please help me to no longer have the need
to hold on to any of it, for the illusion
of safety and protection. I am ready
to be permanently, forever released
from these shackles...
How is it going? I've lost almost 70 lbs in 6 months. Are you still at it? You need help? Dont beg, you can do it. I'll help.
I’m a new subscriber. Thank you for the helpful information ❣️
This makes sense. The last restrictive diet I followed was keto. At first it was great. Then good. Then boring. Then gross. I was so sick of the foods after 6 months. I craved bread and starchy vegetables. When I got a horrible keto rash on my face, shoulders, back, and torso, I finally caved and ate potatoes and beans. The week long rash began to clear in just hours. I quit all dieting, resigned to just getting old and fat -- until IF. Now I feel amazing. No more bloating, no yo-yo-ing weight gains, no afternoon energy crashes, and best of all, no restricted foods. I crave wholesome, whole, nutrient dense foods most of the time, but I can also indulge in the occasional donut at the end of my window when I'm close to full (I never want a second one anymore). We just spent three weeks in Quebec eating all of the pastries (I just followed an easy 12:12 window most days), and it only took a week of going back to my normal IF pattern (20:4 is my favorite) to drop the vacation bloat. I was about 135 lbs when we left, about 140 when we got home, and I was down to 130 with no special effort. Maybe I'll even see 125 again someday (I'm 54, and that was my high school weight). And if not, who cares? I'm so grateful for this. Simple, sustainable, and free. No plans, no special foods. And I just move my window up or down to accommodate family gatherings or special occasions (and I'm just gonna continue to have long windows on vacations and eat ALL the yummy foods). This is living. Just wish I had known about this 30 years ago.
I know, so easy and so sustainable.
Very analytical
What I love about Dr. Fung is his simple and low key, no frills style. Its easy to understand and even easier to follow and IT WORKS!! His advice needs to reach more people And for that I feel he needs to work on his video thumbnail. Thank you.
Actually the thumbnails have been cracking me up text - I love them 😂
@@anitas5817 I agree. I mean seeing the not so pleased comments, I thought about it again. But...
I love the playfulness!🙃 It makes me think of the kind and caring things Dr. Fung has said in some interviews.
Thank you Dr. Fung. I wish you well and happy always!
Another Awesome video Thanks Much Love ❤❤❤
I don't touch food from around 11 pm- 3am,to about 8-9 pm the next day, just MCT oil in my morning coffee, and heavy cream in my late afternoon coffee, I've been doing this over a year now, but been on keto 2 1/2 years, I don't even get hungry outside of my eating window once your body gets used to eating a ceratin way, and certain times, it becomes very easy to do.
AMEN! Don’t eat all the time! With IF and OMAD, I already lost 12 lbs.! 💪🏽
Thanks, Dr Fung!!!
I am definitely sharing it ! It's so genuine and honest. And it cleared my greatest doubt..to the point of saying 'aa huh so that was the reason'. Regards from another doctor from India 🙏
Thank you Dr. Fung
I've had severe health anxiety ever since I went into hospital for High Blood Pressure.I am obese and I started doing 24 to 48 hours fasting weekly depending on my mode. I go to the gym 5 days a week and I have lost 39 lbs(18kg) in about 2 and the half months. People are asking me if I am sick and it is depressing me and making my health anxiety worst with the feeling something is wrong and that's why i am losing much weight at a fast pace even thou i know I am putting in the work. I am still obese and want to lost more weight but the comments I am getting about being sick is discouraging me to continue and making my anxiety worst,when it was getting better.
THANK YOU …you are amazing !!!!
Thank you so much, Dr. Fung for sharing your knowledge with us. You’re amazing!
L
I finally got to understand the whatness and howness of "food intakes" when I started watching the informative videos of Dr. Fung...thanks Dr🤗 I hope you can come up with a more detailed video about why the "plateauing" of weight somewhere along the fasting process happens..
Good morning Dr. Jason!
I love the bling Dr! Thank you for the informative videos!
I am from sri lanka following your diet fasting lost 4 kgwithing 4 month.No any illness .But i have to lost 6 kg to maintain my healthy lifestyle .
Thankyou for your great advice doctor. ❤️🙏🙏
Very good points. Variety and convenience of food are the main culprits of obesity.
Of course we learn, you are so specific, I love you videos
Excellent explanation!
Thank you for the video Dr Fung 👍👏👏
Variety in eating back 50 or 60 years ago was having a different entrée on the dining table for dinner. Today, variety is heading to a different fast food joint for dinner.
I respect dr jason fung a lot but the
Only thing is that one can get tired of fasting too...
Needed this today. Thanks, Doc!
Well said, an excellent explanation as always. Thank you.
A balance of the same staple foods with some variety for pleasure is important. In our particularly convenient food rich toxic environment we have to be even more diligent to plan and prep for successful meals/ fasting.
I just stopped viewing food as a main source of pleasure in my life. Had given me much more time for actually pleasing things
@@OatmealTheCrazy That's a good way to put it.
Jason, thanks again for your wisdom on these matters; I cannot thank you enough for setting the record straight for me. This system has worked out great for me thus far, however, as you stated we are all different and some things I may have overdone, but overall it is the answer. I have some tweaking to work on.
Thank you for another wonderful video.
Thank you!
That gold chain tho' 👍
😂😂😂
Don't diss the doc 🤣
Bling bling 🤑
I must say I do like your practical thoughts
Also in the late 70's the microwave oven came along to most people's homes, making it super easy and convenient to heat up foods that were mostly processed foods created for the microwave meals market; making people even more obese.
Thanks!
Dr Fung, This is sooooo true!! Thank you this explanation !
I thing that I can share based on my personal experience is that fasting TREMENDOUSLY improves the symptoms of PCOS and can cure infertility…after suffering through infertility for 15 years , multiple failed IVF cycles, years of fertility drugs…I almost gave up, then I watched a video by a fertility doctor who recommended Dr Fung’s fasting regime for improving fertility…at age 38 I became pregnant naturally after fasting for 3 months ..I had my daughter and then again at age 40 I had conceived my son after again fasting for about 3 months….it changed my hormones which then regulated my reproductive system….I CANNOT recommend enough how powerful fasting is for fertility
Didn't watch the video but am starting my 'Dr Fung Recommended Cookie Diet' right now..
Everybody's told to eat slowly and chew properly their food, partly because it does help to kick in the satiety signal sooner, so you don't over eat. I can testify to that because I've always been a slow eater and as a result I have a very small stomach that simply can not handle the amounts of food I see everyone else eat in one sitting, I would be literally sick if I tried to do that.
Now, however, I am told that to get my insulin down I should be having just one meal a day, or two at the most. I understand the reasons very well, but I simply can't do this - I know, I've tried. I became malnourished because I have to continue to eat child-size portions and if I can only eat once or twice a day I simply don't get enough calories or nutrients to be able to function normally. I get very weak and listless and even my voice starts to fade. So I need to eat three, sometimes four times a day just to get enough food to sustain me. I eat clean, but I can't shed the weight unless I fast to lose the excess I have gained during feeding days, in an endless cycle.
It's ironic that those who disregarded the so-called good advice and gorge themselves on food at every meal and have stretched out, over enlarged stomachs can do the OMAD life style, whereas someone with insulin resistance like me can't benefit from it because I did the right thing all my life. Just saying.
It also helps breaking down nutrients. If you don't chew your food properly until liquified it will be much harder for your digestive system to process. This is especially true for vegetable matters. But we are all in a hurry these days, and most of us have become fast, unconcious eaters.
@@RedErin I'm a carnivore, as most vegetables make me sick. This is true of people like me who have leaky gut. Also, I've noticed that people are always told to listen to their body... until their body tells them something that contradicts dogma. Then their body is wrong, and the fact that you're fat and sick is entered as proof that you can't trust yourself or your body...
Eat whole foods and avoid processed foods as much as possible. Organic veggies if you can afford it. Grass fed, steroid free beef if you can afford it. Healthy food is expensive, but cheap processed food will kill you.
I was used to fast. But now I just want to eat more and more. +10kg after I stop fasting! 😢
Same i did omad and adf for some months and it worked. I gained the weight back and now I'm so lazy to fast.
intermittent fasting is something that you commit to. Don't stop
@@EE-hi4re fasting made me restrict myself from eating. Now all I want to do is eating. Never experienced this before I started my fasting journey.
@@halosunnah5446 it takes a bit of getting used to in the beginning. You'll get used to it
@@EE-hi4re it's not a beginning I would say. I fast for 1 year. And stop fasting for 1 year.
it takes time and patience... people forget that our bodies didn't store the fat on it in one day... it has stored for years.
100%
Thankyou Dr Fung. Its simple, effective
Your advise is very helpfull thankyou, God bless you.
Can you do an in-depth video on fasting and thyroid?
One of the main root causes of allergies and autoimmune diseases such as Hashimoto's is a leaky gut. Even aging is affected by a leaky gut as your immune system squanders precious NAD fighting infiltration of bacteria into the blood stream. This can be corrected with a combination of 72+ hour fasts, avoiding lectins, sugar, bread and pasta and supplementation with gut healthy foods.
Gut Health and Leaky Gut supplements
Glutamine/L-glutamine
Berberine
Butyrate
Taurine
Glycine
AAKG
Marshmallow Root
Collagen
Hyalarunic acid
Inulin/prebiotics such as cabbage and sauerkraut
I have Hashimotos. My thyroid felt swollen and it was uncomfortable when swallowing. I did a 3 day fast and it went back to normal.
smart.. a good take.. lots to consider
Well said !
Thank you Dr. Fung!
Great information...
I have never heard anyone say it so simply and clearly. Diets succeed and fail for the same reason: monotony.
From a lifetime of observation, I would say that is correct.
Love the bling Dr. Fung! Keep it coming! …….
