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.

I’m so thankful that you are out there catching these reports and presenting the facts to counter these negative messages! I don’t think “they” are attacking IF-it’s the keto diet (& IF is part of that life style) that is at the center of the attack!! More and more people are adopting this lifestyle and it’s impacting so many other diet programs plus the sugar industry…so a lot of $$ behind conducting studies to bring down the keto lifestyle!! Thank you Thomas!!

The food industry needs people to consistently eat to keep their profits high. They want people to eat their full 3 meals a day with snacks in between.

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 !

IF has helped my IBS so far, eating from 12-7pm. Not having to eat in the morning is so liberating.

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.

I love your nuanced and logical approach 🙂 So many people love to cherry pick data for a narrative or "lie by omission", it's super annoying. CONTEXT always matters!

[gibbens]

My take-away; muscle strength went up, muscle bulk went down. As a runner/cyclist perfect!

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. IF has changed my life for the better in so many ways. And I appreciate your videos getting me started back in 2017. Keep spreading the word and helping people.

The title panicked me becuz I lift weights and have been on IF for about 1 year and it's been working very well for me

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.

Study or no study. I will never go back to a life without intermittent fasting.

[SimplyHuman]

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.

[jerlynlecompte]

Can't do keto or If, but appreciate your sharing your knowledge of our bodies and how they respond. Thank you so much!

[paltek]

many thanks for clearing the air Thomas

[Servant_Of_The_Great]

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!!! 👍

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.

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 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

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.
