Had a buddy from Colorado Springs that was a weightlifter/body builder guy. He would fast the day before a competition, said it made him a little more cut. Probably urban legend, but it sort of looked like it to me too. If I fast for a day, water and maybe some juice if you I get hypoglycemic and need some calories, it sort of clears things out, so to speak.

I have found that not eating late in the day works well for me, particularly if I feel like I am a little heavy and want to drop some weight. For example, don't eat after 1700. I am an early riser, but don't always eat breakfast. Drink some water when you get the urge to have a little gnosh. I think it is not such a bad thing for your stomach to be empty, particularly if you are going to do something physical, like go for a run or do some yard work. I sleep better if I don't eat late in the day.

Caffeine can suppress your appetite. Can keep you up at night, but it does not really do me like that much. I like coffee and tea, having an iced coffee as I type this.

The trick is to not eat if you are not hungry.
