I tried an interesting experiment for myself.
I had a little #fasting break of 36hrs. It was really surprising how soon hunger turned off once well past the next meal time. When I started eating again it felt more like I was doing it because I should than because I was very motivated to.
Hunger did come back only after eating first large meal, but I ate barely any more than on an average day perhaps.
Workout performance was typical during the fast (chest day + elliptical, cardio day etc) and I managed my normal amount of general activity just fine. I did feel light and quite good overall.
I haven't tried anything like that before, but I might again. I certainly didn't notice any ill effects, I felt good actually. At the minimum it shaves some calories per week and possibly resets your tastebuds.
Recently I've been having an eating quite 'clean' homecooked period which possibly made it easier than more processed etc foods which incline me to snacking or grazing more.
