I'm 76 years old. On a keto diet and intermittent fasting. In one year I lost 65 lbs. My muscle mass increased significantly. Got off diabetes medicine. Number dropped from ~250 to ~110. Lost man boobs. Pants size 42 to 34. And on and on. Studies are generalized, not specific. May work for an industry, but not for an individual. Have a good day.

@Violet Fem don't feel guilty! Love and respect yourself, don't punish yourself! I used to be over 500 pounds and I didn't get as fit as I am by punishment. Yes I worked hard. Just don't starve yourself to meet anyone else's standard of beauty. You should practice fasting because it makes you feel good and gives you health benefits. I like eating 3 meals a day, starting with a big breakfast to a smaller lunch and then just lean protein low fat dinner. At least 4-5 hours between meals. About once a week or so I'll do a 24hr fast. You need plenty of nutrition to build strength and muscle. Keep training and take good care of yourself! Wishing you all the success towards your goals!

[@ElHolyBoy]

Serendipitous timing. Your content as always seems to coincide with my process. I've been intermittent fasting low carb for 4 months with the primary aim to reduce adipose tissue and reduce inflammatory markers. My inflammatory markers are still very high in particular CRP however I've lost 80 lb. Hemoglobin a1c of 4.9. sky high LDL. All other blood markers are fantastic. Very insulin sensitive at only eight. I've started running and cycling and my leg strength has increased to levels I haven't seen in 15 years. However eating keto high fat was really rough for me and frankly I found Mediterranean / other forms of low carb as effective if not more effective. However I think I need to continue to ramp up my protein consumption given all the additional training I'm doing. Fantastic stuff.

[@ebigarella]

Unfortunately endurance sports aren't really great for what you're trying you achieve. You should try resistance training. Coming from a cyclist here that can't build muscles

[@ElHolyBoy]

@@ebigarella my main goal is actually reducing inflammatory markers and preventing ethosclerosis and any cardiac issues. Not really looking to bulk up and get yoked.

I have been a low carber 12 years now. It has worked great on many levels. Weight, health, bloodwork, etc. Would never return to the low fat, high fibre starvation diet that got me fat. Low fat hell. I had my first child in 1982. Lost 30 pounds just having her. Right afterwards I had an apron of skin which hung to my knees. Cried when I saw it. I had a 23 inch waist when I got pregnant and no one warned me how big the change would be. Likely worse because I was following the low fat food pyramid. The death diet. The skin over years went up some, but never great. When I went low carb the skin improved a lot more, but if I leaned over in front of a mirror I still had a lot of lose hanging skin. About a 7 inch drop. Also lose skin over the body from losing weight. Knees, back of arms, face, neck, etc. I am also old, which also effects skin. Can't change that. I started intermittent time limited fasting last summer. Just a couple of days a week. Did not want to lose weight, but skin. Still have a hang leaning over, but it is at least 2 inches shorter. Maybe a bit more. My arms and above my knees are also looking better. And my neck is also a bit better. All round I am pleased with the results and plan to keep it up. It is really easy to do and does give results.

[@wilburmills4061]

Thomas - I am 66 and have been IF for5 years now. I have actually gained muscle during this time. I do body weight fitness for a few minutes a day in fasted state. I feel and look great.

Then i go to the kitchen and bake me some chicken breast and 45 minutes later i eat steak, eggs, brocoli or cauiliflower or saurkraut, with some nutricional yeast. 30 minutes after that i put a whole lemon, water, some fresh garlic, a piece of ginger, some green juice stuff with phytonutricions in the blender mix the stuff and take some extra Vitamin D3, codliver oil capsules, and ther traceminerals inclusive electrolites. before bed i take a glass of water with ACV.

Its working great.

She finally got her dream body.

I always been inconsequent with my weight training. I used to lose a lot of strength over the months I didn't train on my all day eating regime with carbs. Now I eat mostly carnivore, always IF and sometimes 72hour fasts, when I don't train for a whole year, I pick up training on the same level within a few weeks! It just keeps amaze me.

[@StoneShards]

Seems muscle size is not necessarily directly related to muscle strength...which seems counter-intuitive...Explanation?

[@richardmiddleton7770]

A large part of strength is neurological. Many endurance athletes lift solely for strength because they don't want the weight and bulk of big muscles. In simple terms, strength is trained by lifting very heavy for no more than 5 reps but not to failure with 2 or more minutes of recovery and a lower amount of sets but performed nearly everyday. Hypertrophy training on the other hand is 8-20 reps very close to failure, less time between sets and more sets and performed 2-3 times a week.

It seems to me the biggest key to the study is that those with the restricted time window were fasting every single day, which tends to turn off muscle-building Mtor. Also, as Tom has pointed out in another video, it's a good idea to stop intermittent fasting for a week once every 4 to 6 weeks.

I took up IF approx. 1 year ago. It took about 4 months to start to see a difference but that was mainly due to diet. Once I started “sniffing” at KETO, the lbs began to melt off. I’m a cyclist and wanted to drop pounds for climbing. I’ve dropped 20lbs to date and weigh what I did in high school. It works if that is your goal, but it takes discipline, but not insane amounts of it. I’m living proof.

[@ghffthhhu]

If strength goes up while muscle width goes down, isn't that likely just a bit of lost water? Which also often happens in a deficit due to lower glycogen level

[@AdamScottfit]

It's a tool in the tool box. Health benefits aside, if you just want to improve the way you look, its a preference.

[@TheLucidDreamer12]

The biggest problem with dieting in general is that people misunderstand the Second Law of Thermodynamics' relation to it. Yes, burning more than you consume will result in weight loss, but the other half of the law is that all spontaneous processes have an activation energy. In the case of burning fat, the one thing that raises the activation energy of it is high insulin. Once you stop having high insulin, then the familiar half of the law takes hold. Otherwise, the only thermodynamically favorable process of getting energy would be burning muscle via conversion to glucose.

[@launchpadmcquack4971]

Thomas, I’d love to see you do a video on intermittent fasting while on TRT. If I’m controlling testosterone while practicing IF what are the benefits?

[@roderman93]

So key statement is: eat in a caloric surplus to build muscle and eat in a deficit to lose fat. Doesn’t seem to matter when you eat…. Almost as if I knew this information from somewhere 🤔 Great video, really breaks down the study well!

[@jamesrobertson5370]

[@conniegaylord5206]

Intermitting fasting is normal and natural. Carnivorous animals never eat regularly. It always depend on what and when they are able to catch their prey. Eat to live not live to eat.

[@jont39]

It might be good if you interviewed Dr Gabriel Lyons around muscle and the effect of protein on it

[@ianmackenzie686]

Hmmm...what I'm getting from this is that of I choose autophagy as my goal for IF and longer, I'll need to get over a bit of muscle loss. That's a decent tradeoff for me. Health over silly vanity😁

[@ZGGuesswho]

coming up on 9 years of IF, I have tried going off, but the clarity of mind during the day is worth more. I have hit most of my beginner and intermediate muscle gains so the diminishing returns of a surplus/constant eating isn't worth the risk of constant mtor and IGF1 signaling imo.

[@jhc500]

I went and read the pub. To me it reinforces that fasting can be great for overall health, especially for severely overweight people. Loss of fat and reduction is inflammation and related lipid improvements totally outweighs any muscle loss. Once you’re talking about fit people wanting to get extremely fit, the calculus gets more complicated and nuanced, but for the person who knows they’ve been ignoring their health, fasting is almost too good to be true.

How does/would fasting, and/or eating in a calorie deficit for specific periods of time to increase fat loss affect Leptin, IGF, and Testosterone levels of someone who is on TRT and taking exogenous Testosterone Cypionate (.125 ml per week subcutaneously) because their body stopped producing Testosterone naturally? Would their T levels, etc go down with calorie reduction just the same as someone with natural Testosterone production? Or would the fact that they're receiving a steady, consistent dose/amount of Testosterone (maintenance levels only, NOT "steroidal levels) offset the negative effects of too much/often of a calorie deficit?

[@davothegreat9990]

Biggest problem with IF awareness to the broader population is it's free. In other words there's no money in it and sadly that's how the modern world works. 😔

[@qe9933]

It's very difficult eating a lot on keto whilst fasting - it's a task in keeping calories at maintenance on non fasting days, as one gets very satiated on this diet! Eye opener though with big calorie deficits. Wonder if it's worth having a few carbs at night to get calories up on occasion as cannot do it on keto alone

I think it's a good test of healthy your diet is; if you have to eat frequently, your diet is not healthy. Like an overweight person feeling a faint when they haven't snacked for 2 hours. Our bodies seem to be designed to eat infrequently, and to have fat as the major energy source.

[@maryherbivorre3393]

I'm vegan and I practice regular fasting. It's incredible. Don't listen to the haters. They're just jealous because they don't have the mental power to succeed.

[@uqox]

People attack intermittent fasting because it's personal. The very idea that you can improve your health by taking scheduled breaks to allow insulin to drop out of your system and switch to burning fat is too simple. If you are counting calories, have paid thousands of dollars over the course of the last 20+ years, you're selling products, etc that have a foundation in eating more than 3 times a day it makes a person *angry* to hear fasting achieves consistent and sustained weight loss and health improvements. No one wants to hear they may have wasted both money and time by following the *gossip* of nutrition. . I only pay attention to studies *that are peer reviewed*. If other scientists and doctors haven't reviewed the findings they are of no use to me. IF is just the name for not eating all throughout the day and feasting on quality foods. Fasting is ancient. Nothing new and very effective at improving longevity.

[@jaymehayes6843]

I think IF has it's place most definitely. I do think those that have a propensity towards eating disorders may want to stay clear from this.

I fast 2-3 times per week. Need more guidance on how to stay out of deficit while IF, especially with longer ones in the 20-36 hour range it’s almost impossible to eat a day’s caloric budget. More manageable to get all the calories in and still eat whole, healthy foods in the 16:8 or 18:6 IF schemes. Otherwise I find myself getting into an automatic deficit that is hard to make up.

Hey man! I’m 20, I eat good, drink only water and lots of it, exercise a ton and I’m just trying a fasting cycle 8on-16off. My cousins won’t try it because they think snacking throughout the day is the best way to gain muscle I think the foods we’re eating and the ways we’re training have a huge impact, but what about our bodies only absorbing certain amounts of protein an hour? Can you gain muscle only eating 8 hours of the day? I feel like it’s obvious you can.. the problem is all of the misinformation on google!

I always seem to lose significant muscle on IF, it worked for me in the past when I was training more, but the physio I'm doing at the moment prohibits that kind of exercise. It is kind of distressing how my body chooses to cannibalize muscle over fat.... Something must be awry with my hormones.

You say that we should not fast every day. But I want to do 16:8 as a standard for my life. Is this bad?

[@Magnulus76]

It sounds to me like intermittent fasting was roughly equivalent to a slight cut, in terms of what it does to body composition.

Surely the calorie deficit in the tre group played a massive role in the reduction of insulin resistance?

[@mjabdus86]

How do you test insulin sensitivity or resistance?

Do you eat Chick N’ Skin Fried Chicken Skins? I'm looking for snack ideas to take to work 💜

Great video as usual. Are there any natural ways to keep testosterone levels up while having a small caloric deficiency? Not sure my caloric rate has decreased much since I started intermittent fasting but guessing it has gone down some even if it's just from choosing better foods to eat. I really don't want to lose testosterone levels or sex drive being that happy wife happy life lol.

After breaking your fast when can u mix carbs n fats?

Nutrition library did a video on this exact study also.

I've always been told that fasting, calorie deficit and weight loss increase testosterone levels, now i don't know what to think anymore 🤷‍♂️

[@bismarkbizmark5639]

If TRE is supposed to increase both androgen receptor density and HGH, it seems peculiar that there was any muscle mass loss. But if muscles increased in strength or endurance, maybe it was water loss.

Easily debunked, the proof is in the pudding. Intermittent fasting has been of upmost importance to my 100 lbs weight loss journey and muscle building journey 💪🏻

You're absolutely right. I've lost 110 lbs in 3 years with intermittent fasting. And have been resistance training and Cardio for about 18 months. Never been more fit and feel amazing

A lot of angry Italian mothers are going after the intermittent fasting camp because people arent eating their food 😂

[@lauragardner129]

I have heard you say on another video that fasting for over 48 hours will result in muscle loss.Is that true?
