The “End” of Fasting - Shocking New Study that Has the Internet Up in Arms… is it legit? 

If you still stand with fasting, give me a “heck yeah” in the comments!

big pharma doesnt like that fasting is free

The largest and most important effect fasting has done for me is the mental strength. It helped me understand that when I am hungry it's just another feeling. I don't need to immediately react to it, I can think about it and better understand it and myself.

Heck yeah lost 140lbs and reversed all my metabolic illness, de-aged about 20 years, in 11 months Fasting, up to 15 days but mostly 24-48 hours, and ketovore screw the science, I beat food addiction, all cravings and saved my life

They can publish another 50 studies if they need to. I was fat and hungry for over 20 years. My life changed for the MUCH better when I started focusing on nutrient dense food, healthy fats, and skipping breakfast if I wasn't hungry. SPOILER: When you get enough protein, fat, and nutrient density, the hunger goes away for LONG periods of time while you get happier.

I think the primary focus of fasting studies was never really about losing weight; that was a secondary discovery. The real interest was in how fasting affects our cells and promotes rejuvenation. For example, Dr. Valter Longo and Dr. David Sinclair have both highlighted the cellular benefits of fasting. Their research shows that fasting can trigger processes that repair and regenerate cells, enhancing overall health and longevity. Weight loss turned out to be a side effect due to better control of total calorie intake. Later studies focusing specifically on weight loss found that fasting alone isn't the key. The real magic lies in how fasting can improve cellular health and potentially extend our lifespan. I think this is also a more important part in life to focus on right now with all health issues we are facing!

Fasting was very effective for me personally.

My neighbor is 85 ripped ,looks like if he's on his 40s I told him what he do he said he's been fasting since when he was in his 30s and eating clean ,fruits veggies,and proteins especially eggs 💯

I've been following fasting protocols since 1978! I just finished a 42hr fast! I love it and I will never stop! I'm 64 and I look and feel fabulous; no tiredness, no illness, no depression! I hate, hate hate "dieting"!

Heck yeah. Went from an unhealthy 235+ to 200. No shortness of breath. Sleep better. Just all around feeling better. 46yo and in the best shape in years. 16-8 during the week and mindful eating on the weekend. While fasting may help you reach a goal, its the journey is what changes you.

HECK YEAH!!!!! Will NEVER NOT FAST the rest of my life! Thankful I found your videos years ago!!! Fasting is literally the simplest thing to do to better our health. Thank you!!! 💙💙

8:00 am to 6:00 pm? You mean the traditional window within which people eat? lol. Great video picking this apart.

I don't understand why people have a hard time with this. Every time you eat, your pancreas releases Insulin. While Insulin is elevated a person cannot burn fat. decreasing the amount of times that Insulin is released of course leads to fat loss. Simple, eat fewer meals!

Fasting and politics... The two major sins you should not discuss with friends...

Health in people has risen sharply in the past six years. It is appalling to hear so many doctors denounce fasting for longevity.

Eh fasting has worked for me on numerous occasions so I'll stick to it.

Fasting and ketone metabolism has changed my life in so many ways. People can make a study to say what they want but real outcomes mean more to me than some bullshit study. Also people don't understand that it takes more than 14 hours to switch to ketones to any meaningful degree if you were eating sugars and carbs. The benefit comes from your body fueling from the fat on your body including the visceral organ fat where diseases usually come from. So if someone is eating a carb based diet, anything under 22-24 hours is probably not useful enough to have meaningful change.

Heck Yeah !! I'm in the best shape I've been since I was in my early 20's (in my 40's now) and it's because I started IF after last Thanksgiving and followed a lot of your advice. Your channel and IG have been extremely helpful. Thank you for some of the best content out there!

Hmmm, this is incredible 😲 😂 The Food industry Guards are at war. When you avoid food after 6pm in any community, you're definitely a culprit killing the night scene. 😅 They n33d you nibbling ALL DAY LONG

I find that 13 or 14 hours is the sweet spot for me as far as fasting for the long consistent term.

I wonder if this push against fasting has anything to do with Ozemptic and other pharmaceutical weight loss drugs.

Honestly I’m 43 and due to fasting, most people say I look 33. Fasting is the fountain of youth.

Fasting makes you less hungry so you restric calories=eating less.I feel good for years eating in a time restricted window and have convinced many people to do so

Every Scientific discovery has an expiration date

I still do Intermittent Fasting because the prices of food today are out of control and I have two kids. I'm dead ass serious about this.

I once did a fasting experiment on myself. For four weeks, I ate normally, only restricting calories. For the next four weeks, I kept the weekly average calories the same, but fasted for two days a week. My exercise levels were the same in both periods. Normally, weight loss slows as a diet goes on. This time, I lost a few pounds more in the fasting month than I did in the non-fasting month. It was enough to convince me that fasting does work, but it was not sustainable for me. I find it easier to maintain a calorie target eating five small meals a day. For others, intermittent fasting is easier. Whatever works best for you is a win!

There is a guy who got a Nobel prize for his work on fasting. To say fasting has no benefit over calorie-restricted eating feels more like a hit-job than a true study.

Im doing 16 8 and 14 10 alternating every other day. I did one 24 hr fast 2 weeks in. Eatling under 50g ofcarbs a day and shooting for 110 g of protein a day, more if i workout. Ive lossed 15lbs. it will be a month next thursday, hoping to make it at least 17 lbs. I am walking on an incline on treadmill for at least 30 min+ small amount of weight training, 4 days a week. I am a 6'1 female who was at an obese bmi so i did start off burning a lot, like he discussed in the video. Fasting works for me, so ill stick to it.

Good analysis. Thanks.

Dude, IF is just the most satisfying way to eat in a deficit. The science means nothing to me.

I’ve lost 100lbs since last Sept. while intermittent fasting! It’s the only thing that has worked and has not left me starving! I respect studies, but everyone is different and like you said these subjects are rodents or not obese! Thank you for all of your info and “Heck Yeah” I stand by fasting! ❤

fasting works for me !!! the end.

I think investors should always put their cash to work, especially In 2024, we'll start to see more market diversification. I'm hoping to invest about $350k of my savings in stocks against next year. Hope to make millions in 2024

This is why I hate when trends become mainstream. And work. They become denounced.. that’s a sign that it’s good for you

what a bunch of BS!!! I only eat one to maybe two meals a day and then may go one to two days without eating anything. This has led me to lose 42 lbs, my A1C is at 5, my blood pressure is excellent, by heart rate is close to my early thirties and I'm almost 70. My health hasn't been this good in decades!!! My diabetic meds are being reduced and hopefully soon will be eliminated. My Dr. says 'keep up what your doing'. I''ve had to buy all new clothes and that is a good thing. The old stuff went to Good Will Industries. This is what works for me!!!!

Thank you for doing this work 🙏🏼

Heck yeah! I find it's a great tool for achieving mental clarity and cultivating discipline.

People have been fasting since the stone age lol

Corporations need a justification to make you consume more. Fasting becomes popular - they try to diminish this impact. Piece of conspiracy😊 Do we know who sponsored those trials?

Lost 50lbs after pregnancy after implementing a fasting lifestyle. Never have I ever had this much lean muscle and shocked that my skin isn’t sagging after a 50lb weight loss and my age (41). Fasting has been the “magic pill” I’ve always been looking for.

I am 48 years old and after being suddenly handicapped due to a surgeon who cut off my hip flexors I have not been able to walk much at all for the last two years and have been left alone in isolation at home, I now for the first time in my life suffer from obesity with a BMI of 31.7, abdominal fat, and sudden muscle loss with cramps. I experience high inflammation and pain. My heart rate rises with little exertion, making me feel exhausted and breathless. I have chest pressure and notice my heart works hard even with small activities, causing me to sweat heavily. Additionally, I have painful fatty deposits associated with Dercum's disease in the lymph areas under my arms and groin and asymmetrical abdominal fat. I have pain on the right side where my liver is located and have noted lymphatic issues. I experience nerve pain in my ankle and hip following a medical injury, and extensive scar tissue that has fused with other tissue, making it impossible for me to walk or stand on my left side. A bad surgeon intentionally handicapped me and cut up my left hip. I cannot walk far and use crutches or a walker. I was once a dancer, weighing 76 kilos. Now, I have been isolated at home for more than two years, bedridden 80% of the time and weighing 93 kilos. My family and relatives, who are narcissists, have abandoned me because a handicap doesn't fit their family image. They have no empathy for me, as they only feel anxiety around people who need help. I am deeply grieving and a bit unhinged due to social media abuse and isolation. I eat alone, talk to myself, and cannot go outside despite living in the capital. I see no one but healthcare personnel who gaslight me beyond words. I cannot sleep due to the healthcare injury in my hip, which has also damaged my lower back and foot. The crutches have injured my neck and shoulders, resulting in a frozen shoulder and pain in my left chest and arm. I am utterly exhausted. Life is a literal hell, as I lie awake most of the night with ice on my body to calm the nerve and muscle pains. The cramps are due to muscle imbalances. However, I still need to eat like everyone else. What diet should I follow to improve my situation as best I can on my own? I need to try something different than continuing with Uber Eats daily. Only suggest things if you know what you are talking about. Hopefully, Thomas can read this and advise on what one can do in this health and life crisis, focusing on diet and mental improvement despite my inability to sleep. I fall asleep twice a day, snoring loudly, and wake up with pain like being beaten with a police baton over my hip, foot, ankle, and left side of the neck and shoulder. It's an insane nightmare. I have limited funds and usually order simple ready-made foods like Thai food, McDonald's, salads, or smoothie bowls from Uber Eats. Today, I ordered meat and some better small things from a grocery store because I’ve had enough of fast food. I hate it. But, as I cannot lift my left arm and cannot stand for long, cooking is very difficult and exhausting. I am trying to switch to simpler and cleaner eating, and I do feel better if I eat something like 300 grams of steak with sauerkraut rather than Thai food with white rice or a McDonald’s burger with carrots instead of fries and a Coke Zero. I am fully aware that fast food is not good at all. But, when you have no energy to sit up, stay awake, and feel hungry, and cannot get outside for sunlight, it is very difficult not to rely on Uber Eats. Please advise what I can do in my present situation without judgment. When I was fit and weighed 76 kilos, I danced and did martial arts daily and could do 80 push-ups in a minute. But that is not who I am now. Today, after gaslighting, narcissistic abuse, a family that abandoned me and turned against me, a healthcare system that failed me, and a psychopathic surgeon who intentionally handicapped me, I feel utterly lost. My father, who is a doctor and orthopedic surgeon, prefers to maintain his reputation with his colleagues rather than stand up for his own son. My sister and father, the most jealous narcissists, hated that I was always creative, a dancer, an actor, and later a journalist who lived in five countries. They have no soul, no ambition, and only care about a shallow, fake life filled with name-dropping rich friends. They have no honesty, no honor, and zero empathy for anyone who doesn't make them more famous or rich. So, here I lie, struggling to write this text due to so much inflammation in my hands and lower arms. This is my reality, and you have no idea what hell of abuse I have been through. Please, do not judge but offer advice and support if you can. Thank you for reading to the end. Have a good weekend!

Awesome video, and I always learn something. Thanks Thomas 😊

Thanks Thomas❤

Heck yeah Thanks for the video Thomas

it worked for me -I'll be continuing it

If it works for your goals, who cares for studies anyways?

Nothing will replace fasting, ever

Fasting, for many people, allows to more easily manage calories. Only someone who is completely deluded would think that fasting has some magical powers that allows it to oxidize more fat than what would be achieved by caloric restriction alone. The simple fact that fasting facilitates caloric restriction makes it effective. I personally find it far easier, when I eat fewer meals, to maintain the caloric intake I need to lose or maintain weight. Frequent eating always tempts me to overconsume calories.

Also, when you do the fasting for a certain amount of hours, your insulin response is better and you become insulin sensitive easier so when looking at overall health, the fasting group should be better off because the blood sugar is not going up all the time.

8 1/2 years of time restricted eating changed my life. i am no longer yo-yo dieting, compulsive overeating & my life finally feels “sane”. @ 70 i will never give it up no matter what the studies show. side benefits for me: lost weight, weight now stable my labs all improved Homa IR at 1.1 A1C. 5.3

thank you for taking that apart and putting it back together

I was binge eating several times a week. With Keto and some mild fasting my binges and cravings have completly stopped. I dont obsess over food but still eat good and enough when I eat. So yeah I'll defo stick to it. ❤

I've lost loads of weight on fasting. They will try and make fasting look bad because they can't make money from it.

What works for me 1. I’m better at abstinence than I am at moderation. Once I start eating, I thinking more often about eating . 2. I lost 80 lbs with time restriction eating and keto . My blood pressure went from 150/80 to 106/66 3. I now have more discipline even if I decide to have high carb meal or celebration

Fasting is magic. I'm just combining it and in a month l😂 massive results. You cannot stela my experience with experiments

Heck yeah!

I don't intentionally fast but I like to get up in the morning and have my coffee and not eat until 11 or 12 then I don't eat after dinner. But I do follow low carb and it works for me

8am to 6pm eating window was called fasting ? 😂😂😂

Heck yeah!!! My protocol has been 18:6, a caloric deficit, and an eating window from 1pm - 7pm with training 5 days a week. However, as you stated reducing IR is key to lasting fat loss. So yes I fast but fat loss is only part of it. Reduced IR and autophagy or my main reasons. Also the fact that less effort needs to be expended to burn fat is pretty good bonus!!

This Lumen sounds interesting. Having to pay a monthly fee but billed for a year. Not so much. Is this subscription required to use this device?

You cut through and found the holes!! AND the proof of the benefits of IF. You're the best, Thomas.

Congratulations. Good analysis.

"Heck yeah".... Thanks for the great breakdown

Great info! Yeah, that eating window was way too short.

Always great nuanced content - more of this please! great stuff! For me personally IF gives me the mental clarity I need for, so I will never give up :)

Can't always depend on science. You have to experiment on yourself. Real science.

I think that the biggest issue is the definition of what an actual MEAL is? What is a meal? You can eat a bag of chips and salsa and make it a meal. You can have a frozen dinner and have a meal. You can have large amounts of the right meal and have no damage to any of your stats OR eat a small amount of the wrong material and absolutely destroy every data point you are measuring. Calories are not all the same. Some calories stick to you like super glue, while others heal diseases, repair tissue, shrink size, dump fat, build muscle, improve overall health. The discussion to me isn't to eat or not to eat, but what to eat, when I eat, because we all must eat. So, once again, "what's a meal or what makes the perfect meal?" - that is the question.

I had a very restrictive vegan diet for about 25 years. I ate only twice per day and most days my last meal of the day was before 4pm. No snacking at all. Most days, I would get at least 16-18 hours between my last meal and first. Most of my calories came from beans, rice, nuts, fruits and veggies. All organic. No dairy, no meat for about 25 years with no deviation. My weight just stayed off naturally without hardly any exercise at all. For my height 6ft my natural weight is 172-175 lbs and that is where my weight stayed for all those years. As soon as I started a three meal a day plan, some meals after 4pm and got off a vegan diet, incorporating chicken and dairy, I increased in weight from 172 lb to 235 lb in three years and no matter how long I exercise and try to fast, it does not reduce my weight. I definitely know from experience that going without food daily for about 16-18 hours per day, definitely works in keeping normal natural body weight composition.

Why does it feel like as time goes on the ideal diet was the diet I had before subscribing lol😂😂😂

Not eating for 24 or 36 hours three times or so a month just makes sense. Your digestive system gets a break, you blood sugar goes down, some autopgagy kicks in, your cells get stressed a bit so they get a work out and mentally you have self control, mentally you have dominated your body. You're physically and mentally stronger. Got to be good for your emotions too.

The most important thing about fasting in my opinion is it heals the gut. This can’t be overstated.

Thats why i mostly do 1 day fastiing a week no exercise plan or diet can beat not eating 2500-4000cal a day

I have done IF twice in 4 years. The first time, I got from 280 to 255 but hurt myself and had a vasectomy. So I stopped caring . As of Feb 24, I have gone from 280 to 248 at my lowest, currently 252 . So it works for me

Nope. Fasting works for me.

Have used a Lumen for a couple of years. Great tool.

Looking good Man 😅🤝

If you fast 23 hrs and eat 3000 calories in 1 hr you will gain weight. Same if vice versa. It has to do with calorie amounts. Problem with most is they have no self control so they need to imprison themselves into a time window to eat. Also eating at least 3 times a day helps without craving too much or getting hungry then snacking on crap.

As always good stuff Thomas. This study reminds me of the studies that beef is bad for you without doing studies with organic grass fed beef.

lol. This study was sponsored by all the grocery stores and restaurants. They want everyone eating several meals a day.

Fasting (over the last five years) has given me the flexibility of choosing when to eat. I am NOT beholden to hunger and thus not prone to making bad decisions regarding my eating. As anyone who travels weekly for work will attest, the wrong foods are mostly all one can access when on the road. Thanks to fasting, I can wait for the right food. It's cool when you say, "I'll be home tomorrow. I'll wait to eat then.".

Great work Thomas! I first learned the importance of understanding bioindividualty decades ago from my doctor. It's great to see someone like you finally talking about the importance of understanding the biochemistry of our own bodies by whatever means.

If I was fasting to lose weight, this study might matter to me. But I'm not. All the other health benefits are what interest me. If anything, the study in question further encourages me to think those benefits are indeed there, especially since the participants were barely doing a real fast in the first place.

Heck yeah ❤

It has worked for me for many years. I fast for 15 hours a day, sometimes more. I do a 36-48 hour fast twice a year. Today, I am trying to add muscle mass. I eat a lot more protein than I ever have before.

I only use 12/12 but it has immediately made me sleep better and be regular. I don't have a weight issue. I am at my optimum weight.

Thomas, everything you said is exactly what I thought was going to be said before this video and the weight difference is just ridiculous. If the people that so-called fasting were the same weight they would’ve lost even more and they didn’t even move as much and lost the same at a lower weight to begin with, so all they did was show us that fasting works and so many ways. Great response video!

I don’t understand the lumen device, if you’re At work what difference does it make if you’re burning fat or carbs if you don’t have time to go exercise or eat at that time?

Hey man, you got a little of informational content in your ad there.

Heck ya!

As a diabetic, fasting is critical to maintaining my insulin sensitivity and healthy weight.

Let's do a study where participants are randomly assigned to either the "thumbnail" group or the "watch the video" group

Nutrition studies is so weird... Something can work for you extremely well. But then a study says it's pointless or ineffective etc, and youre just completely disillusioned with the whole idea of studies

Heck Yeah! I like your undercut Thomas

We have this idea given to us by big food corporations that we need to be eating all day long. They have a specific food for every minute of the day ( breakfast, morning snack, lunch, afternoon snack, dinner, and then dessert). Most people think they are going to die if they skip a meal; even if they’re not hungry.

Wait till next week

I quit IF about 18 months ago. I’m 64, fit, heavy lifter, no intense cardio but many moderate level walks per week. Fasting doesn’t work for me anymore, but my decision was based on my own needs and body and hormonal state at this age, not studies. I eat when I’m hungry. Sometimes that is after 18 hours, sometimes it’s at 4am. I just listen to my body. I’m also eating more carbs after 14 years of very (very very) low carb. I love your content and appreciate every bit of info you share.

Wow! Didn’t think eating from 8AM to 6PM was even considered fasting

I think I have the starvation gene so fasting keeps my metabolism steady.

I am just amazed how these studies say "fasting" but when you read into it, its simply 14 hours. Like common, thats not fasting, sorry. I have seen studies comparing CR with ADF(Alternate day fasting) which was 48 hours fasting with 1 meal. Results? Both lost weight, BUT! The ADF group had 3x more BDNF levels than the CR group, and more importantly, they had a 52% improvement in insulin levels compared to the CR which only had ~20%

Great video, you took the time in the end to outline why time restricted eating/fasting works so well. I have been doing 16/8 for years but have recently started OMAD a few days per week, I have found a significant difference in the weight loss benefits of fasting. Keep up the great work, this is your best video yet!
