Try eating multiple small meals a day. One easy route is to do three meals a day plus two snacks. Eating smaller but more frequent meals will keep your body feeling satiated and will avoid letting your body go into starvation mode. When in starvation mode, your body will store everything as fat so keep your body happy by eating frequently through out the day.
To lose weight you obviously want to stay away from food that is high in calories, but that doesn't necessarily mean you have to starve. Don't worry so much about how much you're eating, but rather what you're eating. So stay away from the bad stuff and dig in and eat plenty of low-calorie treats like salads, fruits and veggies to satisfy your appetite.
