Stay away from the simple
carbs, such those found
in processed or sugary foods. Eliminate white sugar, flour,
rice, pasta from your diet - those are simple carbs that break down quickly and spike your blood sugar. They're stored as fat, if not used quickly for energy.
Eat plenty of the complex carbs (fiber) found in veggies, whole grains, brown rice, etc. Complex carbs are broken down slowly, so they don't spike your blood sugar and they keep you feeling fuller longer.
