If you want to lose weight permanently, eating several small meals throughout the day to help you with this. Try to eat a small meal consisting of protein, fat, and complex carbohydrate. An example would be; for breakfast 1 hard boiled egg, and an orange, at 10am have a can of tuna on toast, for lunch a Chicken breast and any vegetable, at 2pm have a protein shake, for dinner a chicken breast and vegetable, in the evening have some celery and peanut butter. You get the idea. Avoid sugar, bread, pasta, salt, but not fat.
