Staying motivated and focused, means staying on your structured diet without cheating. The best way to stay on a structured diet without cheating, is automatic portion control. This means live on diet bars or diet formula or diet cookies only as long as you can. Or you live on diet bars or diet formula or diet cookies for one meal, and structured food for your other meal. In general, a diet bar or a diet cookie should have no more than 150 calories and at least 15 grams of protein. A diet formula should have no more than 100 calories and at least 15 grams of protein. Structured portion control works for weight loss. And the lower your total carbohydrate intake, the lower your fat storage, and the lower your hunger.
