Exercise alone in most people that are overweight isn't sufficient for weight loss though, since your body compensates after exercise by making you feel hungrier. Unchecked, most people just eat back the extra calories they burn, which is why most diets attempted through increased exercise alone fail or burn out after a couple of weeks (you'll get sick of killing yourself with exercise only to feel like you're starving to death and you will start eating more).

I'm sure a lot of people can point to top players and note that most of them are skinny, but 1. most of them were already skinny, and 2. the ones that did lose weight play so much that it's physically difficult to eat back all the calories, and for most people it isn't possible to burn that many calories.
