    How many of you guys have been fasting? I didn't include too much of my personal experience this time around, but during my 5 day fast I either had lower libido or I was too exhausted from walking constantly to think about sex, but after refeeding my libido was definitely higher than normal

      I've been doing daily 20 hr fasting and 4 hr feeding windows, but been eating whatever I want during the 4 hours. Losing about 3lbs a week. I'm going to incorporate more protien though instead of carbs. How does this apply to intermittent fasting I wonder 🤨

      Note: One thing that I have always liked about your presentations is the absence of religiosity. Science is not an absolute... like dah.
      Every time that I have water fasted was while I have been celibate. I noticed no libido change for having no reference I am assuming... and only yucky relationships (that I allowed) before hand. You will have to ask this question later on, for when I did get into a relationship anew... I will have to test that.

    I remember a Canadian doctor assisting an aboriginal community in BC suffering from obesity having them prescribed a low-carb diet over a period of time to control their insulin levels.

      The benefits are from the reduced energy in take. When total calories and protein are equated, the randomised controlled human trails shows the ratio of carbs and fat are irrelevant on biomarkers.
      When I've done low carb vs high carb, and kept protein and calories the same, I notice ZERO difference in fat loss biomarkers taken by blood.

    I started doing intermittent fasting (IF) two years ago, weighted 212 lbs. In six months acheived my goal of 160 lbs. My testosterone (T) levels before IF were always bothering me, usually between 230-280 ng/dl. That is borderline low T for men my age (38). After two years of doing IF daily, plus 3 day fasts every 3 months, I'm now at 637 ng/dl, well into the normal range of T levels, also boasting many of the health benefits it also provides to my hormones and body in general. This works!❤

      Ramadan is definitely NOT fasting, it's just moving all your food to outside of daylight hours. The endocrine changes occur when you have NO food for 3 or more days, think of it as a period of starvation, mimicking not being able to have access to any food as if you were on a prolonged hunt in the wild.

    I've practiced prolonged fasting for over 3 years now and I've kept making tremendous gains during this time. My testosterone was 894 ng/dl when I tested it almost 2 years ago and my muscle mass and habits have only gotten better since then so I suspect it's higher now. It's also made cutting very easy and reversed any sort of food addiction I ever had. I literally never crave junk food as whole foods taste amazing to me now and I can go very long without every feeling starved even when quite lean.
    What I've suspected and seems to be true anecdotally is that it boosts hormones and ability to put on muscle mass in the long term.

    This reminds me of the “hard times -> strong men -> easy times -> weak men repeat.” Fasting creates strong men, eating constantly makes weak men quite literally. It makes absolute sense, because animals aren’t mean to live easy lives, they are meant to take on hell and come back stronger. Same with damaging your muscles to build them back.

      from what ive read it seems the current science on the topic is not that you have to "damage your muscles to build them back" but rather stressing the muscles, by pushing them near their limit for a prolonged period, that signals the body to strengthen them.
      you dont have to feel sore to gain muscle, (an indicator of muscle damage) but if you feel sore you probably pushed yourself harder, for longer, and so the gains will likely be bigger.

    In India , we celebrate a festival called navaratri, during which we fast for 9 days straight, and not allowed to eat anything non veg and even onions and garlic , and after the long fast we can eat whatever we want, I always wonder if these age old traditions like the navaratri or Ramadan have some scientific basis, pretty cool to think our ancestors might have figured out the secrets of fasting thousands of years before us , and we still cannot say anything for sure

    The one thing I want to know that didn't seem to be mentioned in the video, unless I'm mistaken, was, how long do the heightened test levels last? Does it drop back down after a few days rapidly? Or gradually return to the pre-fast levels? Could there hypothetically be a way to do a fast cycle go increase your over all testosterone levels, or would the benefits be negligible, specifically from a training standpoint.

    Hi Joseph, great video as always. I’m a bit confused by your description of refeeding syndrome. I agree that there is a massive electrolyte flux into the cells, “diluting” the blood, but this would not increase blood volume (10:18) but rather decrease it. Furthermore, my understanding is that the electrolyte imbalance (specifically hypophosphatemia), coupled with insulin’s downstream effects, rapidly depletes energy stores, causing myocardial ischemia, rhabdomyolysis, and respiratory failure, leading to death. I think the myocardial ischemia can cause “heart failure,” if the person survives the acute phase, and the ischemia can decrease cardiac function and lead to heart failure in the more chronic setting. However, I think usually in the acute setting, the electrolyte imbalance causes a fatal arrhythmia, which is the more common cause of death from refeeding syndrome.
    Very minor correction, but otherwise great video!

And I intend to follow that a day or two later with protein rich yet light foods such as a hard or soft boiled egg, etc. Had labs done last Friday on day 19 and my T levels were just under 800.

If you call yourself a bodybuilder, that means you are willing to devote a lot of your time for maximal effects, for the day of the competition. Most people just want to be lean, somewhat stronger with the minimal amount of time, effort and attention. Im not convinced that high testosterone for like 3 days is massively better than 5 days, biology is more complicated than that. A hormonal spike serves as a signal anyways. Also growth hormone is increased WHILE fasting and drops when refeeding as far as i know.

I started having horrible cramps within a week of increasing the workout time. I was working out in a warm garage and sweating profusely. My wife suggested some type of salts and I ended up getting LMNT. It put an immediate stop to the cramps!
    I quit using it and the cramps returned within 5-6 days so now my standard pre workout is an LMNT and 5g creatine. I’ve read things about creatine absorbing better with salt, so why not?
    I’m now on a 138 day cruise and typically hit the gym 10-12 times a week. I brought enough LMNT to take one a day for the trip. No cramps so far! Legit stuff.

    The only issue is, you'd have to keep repeating it to maintain that testosterone level.. The rapid spike after the refeeding would stabilize back to normal level in 5-6 days.. Based on my experience, the only sustainable fasting method to maintain testosterone is the weekly 36-hour one.. Eat dinner on Saturday, again eat breakfast on Monday..

    Hi!! Long time viewer of your channel and love your videos. I'm curious about height growth in adults but couldn't find anything substantial online. Could you do a video on that maybe? Would be awesome...😁😁

    I've always found eggs to be a very safe way to break a fast. After long fasts I usually use a bone broth, but always include boiled eggs when I break a fast. I work out pretty hard while fasting and on a ten or eleven day fast I know I lose some muscle, but it comes back so fast on a high protein diet I really don't worry about it. Mostly I keep my fasts between three and five days to avoid the lose of muscle and add more muscle when I break the fast.

      yup agree - calculate you last day of fasting with two boiled eggs and that is your meal of the day and the next day add some veggies.

      You don’t lose muscle on a fast. That doesn’t happen, your body does not burn anything but fat, glucose, or old protein (through autophagy). You only lose muscle if you don’t use it

    Subjective experience 100% agrees. I’ve always felt like the benefits of fasting hit around 48-72 hours after ending the fast. Say you fast for a day on a sunday. Make a note of how you’re feeling the following wednesday. Want to feel at your best for a party in the weekend? Fast for a day or 48h if you can handle it, on monday-tuesday. Peace!

    I’m already fasting . No eating no drinking from dawn to dust . But I have decided to quit workout for one month to allow my muscles to rest properly.
