Anecdote: I tried intermittent fasting for 11 months with very, very little to show for it. I did the 18 hours off and 6 hours of eating plan. I have also tried a strict vegetarian diet for 6 months with no real changes in blood work. My Cholesterol didn't move to the dismay of my PCP and myself quite frankly. Biology: I am a professional Firefighter that ran 1000 miles and bicycled 250 miles during this time frame.…

Have you also tried going a whole day without eating, say 8pm as your last meal and then no eating until 2 days later at 8am, basically 36 hours. Doing that once a week or so is pretty effective. There's a whole host of benefits to longer fasts as well. Helps so much with appetite control, resets your hormones, plus autophagy, etc.

Do you find that you're able to do cognitively demanding tasks while fasting? Even small fasts seem to sap my concentration and critical thinking. Once I eat again I feel like I think better.

I do multi day fasts (water Ott broth fasts, so no carbs) and once I am in ketosis I actually feel like I can concentrate as well as when I eat. It's key to not refeed carbs at all during fasting (no juices, honey, etc). I also occasionally do keto between the fasts which might have helped my metabolism switching to ketosis more quickly. Ketosis is - in brief - a metabolic state where the body primarily used fats to…

I have done a couple 36 hour fasts. What broke me was hunger, not low energy. Didn't feel any less energized than usual, really. But resisting the urge to eat after you've been hungry all day and someone puts a meal in front of you is hard.

in many people’s experience (mine included) there’s phase change sometime in the 48-72 hour mark in which hunger/appetite essentially disappears (some describe it is gone, some as easily ignored background noise) Personally, I’ve gone more than 14 days several times, I usually start when not feeling very well (and lacking appetite) which makes even the first couple of days trivial. If you do want to go farther than 3…

Intermittent fasting has a nice advantage - nobody can make any money off of it. This gives it an inherent legitimacy. Contrast all other fad diets, and essentially every supplement ever sold.

Surely people can make money around it. You cannot sell a void [0] but you can very effectively sell void consulting and magazines. [0] even this is debatable
