"I'd like to create a fasting habit just to experiment, but can't understand how that's even possible when working out on gym daily." I fast twice weekly while maintaining a schedule of high intensity weightlifting (power movements, etc.) and BJJ twice weekly along with two unrelated cardio workouts each week. On Mondays I skip breakfast. On Fridays I skip breakfast and lunch. So these are not very long or extreme fasts by any measure, but they are easy to work into a routine and I definitely feel pronounced health benefits. Inflammatory symptoms drop noticeably after the 24 hour fast and I feel very, very fast and light on my feet for running and martial arts. The 24 hour fast (on fridays) happens on my rest day, which presumably you have. I also make it easy by sleeping in that day. The shorter fast (Mondays) is a day that I only do a cardio workout. I agree with you that multi day fasts would be incompatible with a high level of high intensity exercise. I think my single 24 hour fast each week is about the limit of what I could do and still maintain high intensity outputs like powerlifting and martial arts. I strongly encourage you to try it. It's free. It gives you an extra hour or three each week to do things other than eating (and you avoid the context switch of activity-lunch-activity) and it's possible that, like me, you'll feel great.
