Maybe stick with just one 36 hr fast for now until it’s easy. If it’s this hard, counting down the seconds until it’s over, doing that multiple times a week may be too much.
Depends on your goals. Is it religious, spiritual, for a health condition, for weight, for mental fortitude?
I’ve been doing a 16-20 hr “fasted” and 4-8 feeding window for years. There’s benefits for sure, but I’ve become not so strict with it in the last year or so. It depends on the goal. Some weekends I eat a good early breakfast, or I just let calories fluctuate from day to day and week to week. If I think about eating on a longer schedule, not just about one day, I can eat less one day if I feel like it and more another day if it’s a time to feast. I think the key with long-term fasting and other diets is the flexibility. I can run fairly well on low calories, but I can run phenomenally well on more, depending on the task and situation. I wouldn’t even call it fasting anymore. Anything less than 24 hrs, for me, not fasting at all.
The science seems to be trending more towards calorie fluctuation, for health and weight management, not so much not eating for a period and then eating a ton. Depends on diet and lifestyle, too. Outside of religious and spiritual fasting, totally strict “fasting” may not be all it’s been made to be in recent times. Same goes for all diets, eating styles, etc. There is no one perfect way, it’s a negotiation of forces.
I think there’s probably nothing wrong with one totally fasted 24 hrs per week and one totally feasting 24 hrs, with food as needed the rest of the time. Too many 24hr+ fasting in too short a time frame really does put you at greater risk of gallstones, from what I’ve gathered.
Just to finish, I’ll say fasting and feasting are equally important. Man cannot live by bread alone, but he does need a sandwich once in a while.
Balance.
