It's ultimately a heuristic for CICO. Its benefits (or issues) largely depend on what your lifestyle is. If you exercise at any level of intensity, you will lose fitness, but you'll also lose weight.

did a lot of 16/8 last year while dieting, basically just skipping breakfast. pro: easy to cut calories con: harder to get enough protein, but not a huge issue also did a 24 hour fast after christmas. pro: make up the caloric difference of all the chocolate con: nothing really lol

I did 48 hours and regularly do intermittent fasting. 48 hours I felt no more benefits than my usual 16 hour and it was Fkn harder but apparently it’s good for the long term. But definitely recommend intermittent fasting. I’ve never been in great shape without doing that.

I am doing a lot of fasting. Everyday by eating only once a day usually. A few days long fast also from time to time. I feel better when fasting often, for energy and for emotional stability.

Have done a few 72hrs, hard if have a physical job once your past halfway it's all the same. Really zoned in and focused. Good long term health benefits, good for a body reset

Try to do a 36 hr fast one a quarter. I’ve done 4 72 hr fasts (fasting = water and black coffee for me). Started after listening to Dom D’Agastino and Peter Attila talk about it. Everyone is different. For me, I learned how much eating is tied to pleasure and enjoy the cognitive boosts (clearer thinking)
Fitness
I did 10 days, First 3 were bone broth and juices, Next 4 were water only, Final 3 were bone broth and juices again. Water only was insane and I needed to supplement with basic minerals to fight off sickness. Overall the health benefits were great but going forward I will stick to a 2-3 day of bone broth and juice.
Fitness
i’ve done water (and coffee) only fasts for 2-3 days. approx 3-4x per year for the last 3 years. 3 days is the sweet spot. could not recommend more highly.
Fitness
I fast every work day. I don't pack lunch to work & skip bfast. I have 2 meals when I get home, mostly protein and veg. I am at a good weight w good muscle. Pros, according to dr. Peter Attia, is that it merely helps w calorie restriction. Cons - ppl can overeat binging the wrong foods or not enough protein
