I've been practicing intermittent fasting for almost a year now. It works fine for me. I generally eat no breakfast or lunch. I drink only water throughout the day. I run a 5k every morning on an empty stomach with no ill effects. It really helps keep my body fat low and makes me conscious and deliberate about what I eat.
The only exceptions are meals I eat for social reasons (e.g., work lunch meetings) and mornings on which I run a road race and want to ensure I'm at peak performance. I find that when I do break the fast, I'm more hungry sooner.
