Don't eat too few calories. If you want to lose weight, start exercising.
Don't skip or skimp on meals. Your body won't burn the calories as efficiently. You'll also end up hungry before your next meal -- and end up overeating.
Don't focus only on what you've cut out of your diet. Add vegetables, grains and fruit to your meals, and you'll feel well fed.
Don't adopt an all or nothing mentality. Don't give up all your favorite foods; that virtually dooms your diet to failure.
Select a reasonable weight goal.
Be sure to drink enough water. Sometimes when you feel hungry, you are only thirsty.
