2. Your body can only do so much with the tools that it has, so eat well. Aim for a wide variety of foods (instead of the same old thing day in and day out) from every basic food group. Try new fruits and vegetables, ethnic cuisines, and a wide range of lean proteins, including non-meat sources like tofu and legumes. All (or most) of your grains should come from whole, unrefined foods like whole-wheat breads and pasta, and brown rice.
These healthy foods, especially when eaten every three to four hours, will help raise and stabilize your metabolism (and energy) to optimal levels. With fewer ups and downs, your hunger will stay in check, and you’ll have plenty of energy to finish a tough workout.
3. After a workout, refuel with a balanced snack or meal within 30 minutes to 2 hours. Remember, “balanced” does not mean just protein. In fact, most individuals—and even athletes—need less than 10 grams of protein post-workout. Carbohydrates are actually more important, so try to eat an additional 30 to 60 grams at this time, when your body is primed to uptake glycogen into the cells to replace the energy you just used up during your workout.
4. Don’t overlook your huge need for water. Hydration is very important for stable energy levels. (You store 3 molecules of water for every glycogen molecule). Plus, hydration promotes muscle building (powering your metabolism), while dehydration promotes muscle breakdown. So drink up—before, during, and after your workout sessions. The standard “8 cups a day” might not be enough for you, especially if you are exercising regularly.
