Tautology or not, it's actually pretty easy not to eat too much, considering that our bodies are pretty good at telling us when we've had enough.

All you have to do is eat a moderate amount, wait twenty or thirty minutes (for your stomach to start digestion, send signals to your brain, etc), see if you are still hungry, and eat a bit more if you are. If you reach the point where you feel 'full' you've probably overeaten. Not complicated, although many people, myself included, don't always take the time to listen to their bodies or have the self control to stop eating when they are chowing down on something delicious, even though know they've probably had enough.
