3.Before: PB&J
The bread and jelly in this lunchbox staple serve up the carbs. They give you the energy your muscles need during exercise. The peanut butter adds a dose of protein, which helps you feel full, and that can help fend off post-workout cravings and binges. In fact, research shows that eating small amounts of peanuts can help you maintain a healthy weight. Headed on an easy walk or to yoga class? Half a sandwich may be all you need.
4.Before: Oatmeal With Low-Fat Milk and Fruit
Do you work out in the morning? Start your day with a bowl of high-fiber, whole grain oatmeal and fruit. Your body digests the carbs in this combo more slowly, so your blood sugar stays steadier. You’ll feel energized for longer. For an extra dose of protein and bone-building calcium, stir in some low-fat milk.
