Time-restricted feeding can be a great way to reduce calorie intake and thereby lose weight and reduce blood sugar levels. However, I encourage my patients to consume a low-calorie protein shake during the part of the day that they are fasting. I advise them against multi-day fasts.

I fast and excercise. I've gotten stronger and lost weight And my skin looks amazing. And my energy levels and focus are off the chart. I will never stop..

I found fasting as the only way to break the inflammation of my autoimmune disease so I can get my life back. Consuming food does something that flares me up over time. Fasting is a reset. Just my N=1 case.

Fasting is my only option in this economy.

I'm 60 , I fast for 44 hours straight a week, I'm at the gym 4 times a week, I have gained tons of muscle and never felt better both physically and mentally

It's not about calories, it's about minimising insulin levels throughout the day.

@nawfel5813 2 years ago

I used to do intermittent fasting and i had clarity and self confidence, i was more productive in general and it made me feel that i can control the urge to eat, i was less hungry and less angry… combined with running 4 times a week it made loose 13 kg in 5 weeks. I did the 16/8 fasting. I’ll keep doing it!

@terttutemplar 2 years ago

NO! I will never return to " normal". I will only take calories during (maximum) 9 hours per day. I feel much better this way. I do not count calories. I feel much better this way.
Who else is with me?

@kakam458 2 years ago

I have done 18:6 IF for many years and I immediately notice the effects when i don't:

Brain fog, fatigue, unfocus, weird joint and muscle pains (otherwise non-existent)

I also dont eat atleast 5 hours before sleep. My sleep quality and dream recollection is noticably worse when I have late dinner. Sleep quality is probably n. 1 for longevity.

Finally it is probably a good idea to let your stomach, intestines and gut microbiomes rest and recover.

@jemkeystv5717 2 years ago

Yeah, intermittent fasting is the best thing I've done at 59, now 61, I'm not going to stop, it's so nice having a flat stomach again and feeling better than I've felt in decades, it's hard to know what your test subjects are truly eating and how often

@Aquame68 2 years ago

Na I’ll keep fasting. not losing muscle here

@zaneh4842 2 years ago

Would you not think it beneficial to give the digestive system a break? More blood flow to the rest of the body. Additionally less oxidative stress and inflammation in the gut

@mrd799 2 years ago

I've done both, with calorie restriction i was miserable constantly, tired, hungry, with intermittent fasting i had energy, was not hungry and had no cravings, so i think it depends on the person, or let me put it like this, nobody can do a calorie restriction diet as a lifestyle, it wont work i've never seen anyone do it for years, but intermittent fasting you can do as a lifestyle and you even will forget that it's a diet it will just feel normal to you after a while.

If you are going to stop? Stop listening to "experts" and let your own experience prove what works for you.

@nossy232323 2 years ago (edited)

For me intermittent fasting is just easy to restrict my calories. Nothing else has worked long time. But I do eat a lot of protein.

I did one day per week fasting regularly for 2.5 years. In the meantime I gradually increased my exercise volume. After 2.5 years when I was able to regularly run 10km and lifted weight 2x per week, I noticed that fasting is getting harder. I was more irritable, nervous and tired. I gave up on fasting to focus on movement. I still do (24h) fast once in a while but not regularly and not when I'm training hard. BTW I started fasting while recovering from my 3rd chemotherapy in as many years. It was party a way of preventing reoccurrence. It worked. I didn't need a 4th chemo. So, do not discard fasting. It has benefits but do it wisely.

because it's free and healing, and cant be sold!

I do practice fasting. Last year did a 63 day water fast, followed by 40 day water fast. Results were amazing! Lost 155 pounds, diabetes gone, inflammation gone, no loose skin and l don't know what's being sick. No doctors supervision. Everything is possible.

@peterbart3256 2 years ago

You should do a deep dive on the fasting mimicking diet. There is quite a bit of research on it, and the benefits seem to be more consistent compared to intermittent fasting.

@jacklan4103 2 years ago

Dr. Nir Barzilai, who specializes in centenarians and longevity, said that what's good for the muscles may not be good for the rest of the body. Yes, protein may be good to MAINTAIN muscle mass, but excessive protein leads to higher mTOR activity which speeds up the aging process. You don't see centenarians jugging protein shakes and lifting heavy weights. They are usually lean and eat a high diet of complex carbs.
