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.

@@TandZAptLife That is awesome! I'm 57 and I am trying to get back in shape using IF and exercise. So far, lost 5 lbs in about 2 weeks. Haven't noticed any change in muscle mass as of yet.

Started both almost 2 months ago..I've suffered for years from diabetic leg pain torn ACL arthritis inflammation ..long story short 15 years of pain pills cortisone shots diabetic shoe inserts etc. All gone still have very minor pain at times but I'm working out now and finally getting back to LIFE..oh yeah losing weight too.
Cured my pre diabetes metabolic syndrome and blood pressure now 119 over 79 from 140 plus eating 8 times a day weight training all my life and cycling from the age of 50 been fasting and keto for two yrs and all the crap cleared up and I got faster and stronger on the bike ! It works the End !
wake up and live life, go to work and not have to stop for lunch, while the other guys have a 9 oclock break, eat, 12 oclock break eat, then they go home and eat? watching them get slower and more tired right after. just plugging along working, then its sacred dinner time around 6 to replenish for the next day. liberation indeed man

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.
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
@@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.

@@zacharycardiff2774 Yes thanks for reminder. I need to go off the 2 meals more often than I do but I ate a small amount for lunch and felt so guilty about it like I blew my IF
I've been doing healthy keto and intermittent fasting lifestyle for over a year. Along with reversing my T2D with many many other health benefits, my atrophy is reversing as well. 💪
@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!
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.
its easy to make something look bad. 18/6 since July 2018. Saved my life brother. . . at first it seemed hard to build muscle which could be blamed on not eating enough protein/ calories. As soon as i ate way more /mostly meat, the muscle seemed to get bigger with out really trying.
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.
Would definitely trade visceral fat, bit of muscle and inflammation for a leaner, stronger and healthier body that has better insulin sensitivity and is better at absorbing nutrients to build the muscle in the first place!!! 👍
Nice I did IF before. Started working out again a week or so ago and wasn’t going to do IF because ppl have been bashing it lately. Gonna start morow now.
Been IF for a month and a half, combined with strength training and eating healthy, and all water only. Dropped 30 pounds! Pushing through my first 48 hours fast which should end later today 😅 thanks man
I am doing omad everyday and healthy keto. my jobs is intensive on the body. I work with horses. So, lots of cleaning stables, brushing floors, feeding them etc. whole day manual labour. While doing IF OMAD. when i get home at the end of the day i workout too, Lifting weigts etc. Going to work on the bicylcle. Workout in a fasted state. After i worked out i shower cold. 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. I am doing this now for 2 years and fasting atleast 22 hours. I gained muscle mass and lost fat. I am down 2 sizes of pants. I am 186CM tall and i weigh arround 92KG feeling awesome. Its working great.
A girl friend of mine was on a crazy diet with tons of food and protein because her boyfriend said it was the only way to get lean muscle mass. She saw my results and decided to fallow my advice for a couple of months. Last week, she thanked me for the "best lean mass of her life." My simple advice: 8/16 fasting and fasted cardio. She finally got her dream body.
its because most people are to weak to fast, so since they cant have the amazing benefits of fasting, they want to assure themselves and convince others that the benefits aren't worth it.
Thomas, at university, im back on campus with lots of work to do and so its hard trying to stay on keto when im in a convenience store wanting some lunch. could you do a video on your favourite packed lunches or meals that can last for a few hours out of the fridge or that can be kept cool in a lunchbox. thanks, Rob
Been doing OMAD for 2 months. Lost 26 kgs. went from 102 kgs to 76kgs. While doing 2hours of work out. ( 1 hour running + 1 hour weight training) Thank you Thomas, You and Dr.Berg have transformed my life. Also, started taking NMN and RESVERATROL. Man i feel great. Not going back to the old lifestyle. You are a blessing to your viewers Thomas!!
I do OMAD . I was already fit , so jiu Jitsu and lift weights but was bulky. Once I did intermittent fasting I lost 5 KG in a month and look SHREDDED now ! I haven’t lost strength either which is crazy
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.
I can tell you one thing. As soon as you are sick, you do not give a single f for your additional muscle mass. I don't need to look like schwarzenegger, I need to look healthy. And beeing extremly muscular doenst actually mean that you are fit and healthy. I know many people who can lift like crazy, but can not run for more than 1 mile. Get healthy, everything else is optional.
You are incredible Tom! Thank you very much for the overwhelming knowledge you share with the world. God bless you and please keep up this wonderful stuff. Best regards. Omar from Egypt.
I'll tell you what the "problem" is with intermittent fasting! In a phrase, "snacking control"! I people are in control of their snacking, a huge industry will simply collapse! Consumerism is driven by advertising. The marketers are betting they can "persuade" people to desire their snack products--and they're everywhere! If they can't stimulate that desire, they fail...
Strength went up, so apparently fasting stimulated replacement of less energetic bulk with mitochondria dense muscle. Good news for improving pullups and other calisthenics.
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.
@@27jezusno you cant do Intermittent fasting every day. If you're on a 16/8 fasting diet its recommended to do it only 3x a week. Keep your calories below maintenance and do Resistance training .
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!
Tryna get back into IF.. simple 16:8, won't stress myself out too much.. maybe 20:4. Worked well in the past for me but I fell out of it. Cheers for the video, this and comments help to get rid of any doubts and
My testosterone actually went up, and I have been struggling with it even with trt treatments. Since doing keto for almost a year now, testosterone used to be under 200 with out trt, with trt 400/600 range, now with trt and keto 1,000!
12 hours between meals is still fasting! A normal person who eats breakfast at 6 am and snacks till bedtime at 10 pm is only going 8 hours between meals. Doctor doing longevity study reccomends 12 hour fasting. Which is typical apparently in traditional Mediterranean lifestyle.
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.
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?
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.
From my own personal experience I was in taking 130g protein a day and I weigh 130lb and when I implemented intermittent fasting I saw a huge decline in my muscle mass whereas when I was eating in a deficit without IF then I was able to upkeep my muscle mass
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.
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. 😔
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😁
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.
I tried IF for 10 days and gained weight so trashed it. I did the lunch and supper one in a 6 hour window. For years I have never eaten lunch so have reverted to that. Just now cutting portion sizes. Need to lose about 20kgs
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
I do 16:8 with 150g of protein and a slight caloric surplus, CAN I DO THIS EVERY DAY? and continue good gains? Because I see you say don't do IF every day?
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.
Let's see, IF is free, self administered, no health "experts" needed, reduces major metabolic diseases and symptoms, helps with Longevity and overall improves health...I wonder why the powers to be don't like it
I started a 16/8 daily fast a few months ago. My belt got loose and I felt like I probably lost 5 to 10 lbs. I decided to weight myself and was surprised I actually gained a pound! Probably ate less, which tells me my body must have been using my food more efficiently.
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.
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
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.
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.
I have trouble getting my calories in on clean keto, not because I can't, but because going overboard on carbs, any help on this? Anyone any Recommendations?
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
Butcher Box is junk, I listened to your video, placed an order, it took 4.5 days to arrive after they shipped it, I am in WA state, everything arrived thawed and the instruction is to re-freeze everything again. But meat loses quality and digestibility when it's refrozen. At least 2 items were warm to the touch with bubbles inside.
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?
"Eat all the time" was bad info from doctors, I betcha. My aunt had Type I diabetes from age 11 (related to puberty). Her doctors told her to eat 5 small meals a day. And said everybody would be healthier if we all did that. So I presume THAT bad info from doctors is what caused the confusion.
While it’s true TRF can be applied to all nutritional regimens, trying to fast while eating a high carb diet is problematic because satiety is so low. People on high carb diets have to eat all the time so they bonk when trying to fast. I think time-restricted eating is great and isn’t that hard.
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.
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.
The food industry they are concerned if people start eating like they should once to twice a day you will cut their profits in half plus .that’s why the fight .check into all of those who are fighting it and you’ll find a connection to some of the largest food manufacturers on the planet .and governments as well.
Hi Thomas, I’ve got a question which I’m struggling to find any good answers for, wondered if you could help please? You’ve spoken a lot about separating fat and carbs to avoid an insulin spike and storing fat (which I have been), is there a rule in terms of how long after my high protein high fat meal (usually eggs and avocado) I have to wait until I can have a meal which may spike my insulin? (Yogurt, protein shake, etc) Where this ties in to IF is that I’m keeping myself to a 2-4 hour eating window, so I’ve been having an insulin spiking meal around an hour after my high fat meal Any advice would be really appreciated!!
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.
I'm 76 years old. On a keto diet and intermittent fasting.

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.
I am doing this now for 2 years and fasting atleast 22 hours. I gained muscle mass and lost fat. I am down 2 sizes of pants. I am 186CM tall and i weigh arround 92KG feeling awesome. Its working great.
A girl friend of mine was on a crazy diet with tons of food and protein because her boyfriend said it was the only way to get lean muscle mass.
She saw my results and decided to fallow my advice for a couple of months. Last week, she thanked me for the "best lean mass of her life."
My simple advice: 8/16 fasting and fasted cardio.
She finally got her dream body.
its because most people are to weak to fast, so since they cant have the amazing benefits of fasting, they want to assure themselves and convince others that the benefits aren't worth it.
Yes, attacking IF is a excuse for people who is not able to stop eating at all times themselves.
Thomas, at university, im back on campus with lots of work to do and so its hard trying to stay on keto when im in a convenience store wanting some lunch. could you do a video on your favourite packed lunches or meals that can last for a few hours out of the fridge or that can be kept cool in a lunchbox. thanks, Rob
many thanks for clearing the air Thomas
Been doing OMAD for 2 months. Lost 26 kgs. went from 102 kgs to 76kgs. While doing 2hours of work out. ( 1 hour running + 1 hour weight training)
Thank you Thomas, You and Dr.Berg have transformed my life. Also, started taking NMN and RESVERATROL.
Man i feel great. Not going back to the old lifestyle.
You are a blessing to your viewers Thomas!!
Hi how often you worked out. How much recovery days you gave?
@@mayank-kx9tc 5 days a week i workout. 3 days with one day break and 2 days and one day break.
I do OMAD . I was already fit , so jiu Jitsu and lift weights but was bulky.
Once I did intermittent fasting I lost 5 KG in a month and look SHREDDED now !
I haven’t lost strength either which is crazy
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.
I can tell you one thing. As soon as you are sick, you do not give a single f for your additional muscle mass. I don't need to look like schwarzenegger, I need to look healthy. And beeing extremly muscular doenst actually mean that you are fit and healthy. I know many people who can lift like crazy, but can not run for more than 1 mile. Get healthy, everything else is optional.
You are incredible Tom! Thank you very much for the overwhelming knowledge you share with the world. God bless you and please keep up this wonderful stuff. Best regards.

Omar and yo name is salwa tf man😂😂
I'll tell you what the "problem" is with intermittent fasting! In a phrase, "snacking control"! I people are in control of their snacking, a huge industry will simply collapse! Consumerism is driven by advertising. The marketers are betting they can "persuade" people to desire their snack products--and they're everywhere! If they can't stimulate that desire, they fail...
Love your topics Tomasso
Strength went up, so apparently fasting stimulated replacement of less energetic bulk with mitochondria dense muscle. Good news for improving pullups and other calisthenics.
Yes theres a study that says fasting with cr increases mitochondria density
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 am doing it for at least 4 moth straight.. I have realized its not good. I have to increase my eating window i guess
@@27jezusno you cant do Intermittent fasting every day. If you're on a 16/8 fasting diet its recommended to do it only 3x a week. Keep your calories below maintenance and do Resistance training .
@@ricksgiggle8852 i had to stop long ago but thanks..
Would you recommend a protein powder along with the fish and meat I eat. Best for Keto
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!
Tryna get back into IF.. simple 16:8, won't stress myself out too much.. maybe 20:4. Worked well in the past for me but I fell out of it. Cheers for the video, this and comments help to get rid of any doubts and
My testosterone actually went up, and I have been struggling with it even with trt treatments. Since doing keto for almost a year now, testosterone used to be under 200 with out trt, with trt 400/600 range, now with trt and keto 1,000!
It's a tool in the tool box. Health benefits aside, if you just want to improve the way you look, its a preference.
12 hours between meals is still fasting! A normal person who eats breakfast at 6 am and snacks till bedtime at 10 pm is only going 8 hours between meals. Doctor doing longevity study reccomends 12 hour fasting. Which is typical apparently in traditional Mediterranean lifestyle.
This video was extremely helpful. I ran into some of these issues and he puts things into perspective! Thanks for all the info
Add fats to protein so you can absorb the nutrients over a longer amount of time and lower insulin response😎
Thomas you acclaimed that so well thanks
Amazing review. Thank you for for further reinforcing what I am doing 😀
‘They’ don’t want us to have any way to keep ourselves healthy.
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.
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?
Get well.
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.
Intermittant fasting has helped me to Loose 11 kg in 2 years!!
I am Also training during the time 🙏🏻👍🏻
From my own personal experience I was in taking 130g protein a day and I weigh 130lb and when I implemented intermittent fasting I saw a huge decline in my muscle mass whereas when I was eating in a deficit without IF then I was able to upkeep my muscle mass
Thanks Thomas!
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.
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. 😔
The eat-all-the-time group had more water in their muscles due to higher insulin. Also, the candle that burns twice as brightly burns half as long.
So how much protein were they eating?
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😁
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.
I tried IF for 10 days and gained weight so trashed it. I did the lunch and supper one in a 6 hour window.
For years I have never eaten lunch so have reverted to that. Just now cutting portion sizes. Need to lose about 20kgs
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
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.
It might be good if you interviewed Dr Gabriel Lyons around muscle and the effect of protein on it
I do 16:8 with 150g of protein and a slight caloric surplus, CAN I DO THIS EVERY DAY? and continue good gains? Because I see you say don't do IF every day?
Seems muscle size is not necessarily directly related to muscle strength...which seems counter-intuitive...Explanation?
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.
Let's see, IF is free, self administered, no health "experts" needed, reduces major metabolic diseases and symptoms, helps with Longevity and overall improves health...I wonder why the powers to be don't like it
I started a 16/8 daily fast a few months ago. My belt got loose and I felt like I probably lost 5 to 10 lbs. I decided to weight myself and was surprised I actually gained a pound! Probably ate less, which tells me my body must have been using my food more efficiently.
Gained muscles obviously
How do you test insulin sensitivity or resistance?
I've always been told that fasting, calorie deficit and weight loss increase testosterone levels, now i don't know what to think anymore 🤷♂️
After breaking your fast when can u mix carbs n fats?
The thumbnail pic lmfao 😆😆
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.
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
Increase your fat intake, highly calorific, a couple of butter coffees with 50 grams in each 900 calories
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.
#ForwardThinking.
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.
I have trouble getting my calories in on clean keto, not because I can't, but because going overboard on carbs, any help on this? Anyone any Recommendations?
I transitioned from ketovore-carnivore. Higher proteins from the meat will add calories, but you'll be fuller for longer without the carbs!
Yes, just increase added fat. Like add mayonnaise, butter, avocado oil, olive oil, coconut oil etc. Add them to veggies/eggs/steak etc.
Thank y'all! Will definitely try that out
TEAM THOMAS ...Couldn't find protein in study 🤔How much protein did both groups eat❓
Update the podcast Thomas
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 💪🏻
sugar free keto friendly pudding ;)
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
@@kristicarouth5085 that’s awesome! Congratulations on your hard work 😊

Butcher Box is junk, I listened to your video, placed an order, it took 4.5 days to arrive after they shipped it, I am in WA state, everything arrived thawed and the instruction is to re-freeze everything again. But meat loses quality and digestibility when it's refrozen. At least 2 items were warm to the touch with bubbles inside.
Great info
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?
I imagine that if you're overweight, as I am, even in a deficit - if you're on keto - burning fat - the body uses fat before muscle? No?
"Eat all the time" was bad info from doctors, I betcha. My aunt had Type I diabetes from age 11 (related to puberty). Her doctors told her to eat 5 small meals a day. And said everybody would be healthier if we all did that. So I presume THAT bad info from doctors is what caused the confusion.
Great. Thx ☺️ I
While it’s true TRF can be applied to all nutritional regimens, trying to fast while eating a high carb diet is problematic because satiety is so low. People on high carb diets have to eat all the time so they bonk when trying to fast. I think time-restricted eating is great and isn’t that hard.
Do you eat Chick N’ Skin Fried Chicken Skins? I'm looking for snack ideas to take to work 💜
Nice one Tommy lad
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?
Finally.. an image of you that isnt highly photoshopped 😅
Looolol
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.
I lost muscle afta 7 days, reps wit da same barbell weight remained
They say everytime you eat you spike insulin....even if they don't eat carbs..
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.
IF 100%, 50+ years old and rose my testosterone from 15 to 27 nmol/L
What's the best way to know what a deficit is for you?
The food industry they are concerned if people start eating like they should once to twice a day you will cut their profits in half plus .that’s why the fight .check into all of those who are fighting it and you’ll find a connection to some of the largest food manufacturers on the planet .and governments as well.
Hi Thomas, I’ve got a question which I’m struggling to find any good answers for, wondered if you could help please?
You’ve spoken a lot about separating fat and carbs to avoid an insulin spike and storing fat (which I have been), is there a rule in terms of how long after my high protein high fat meal (usually eggs and avocado) I have to wait until I can have a meal which may spike my insulin? (Yogurt, protein shake, etc)
Where this ties in to IF is that I’m keeping myself to a 2-4 hour eating window, so I’ve been having an insulin spiking meal around an hour after my high fat meal
Any advice would be really appreciated!!
Go watch dr. Jason Fung. He is the one dat talks bout insulin spike vrrsus calorie
@@mjt9590 cheers mate, not heard of him, will give it a watch!
The thumbnail looks just like me but with more asymmetrical abs 😅😅😅
I have heard you say on another video that fasting for over 48 hours will result in muscle loss.Is that true?
Intermittent fasting makes my life way easier
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.
