Diet Ideas for Workout - as part of the expert series by GeoBeats. My name is Kim Fortunado with Rebecca Bitzer and Associates. When working out, it is important to properly fuel your body. Some great ideas to eat before a workout include toast with peanut butter, oatmeal with almonds, or a smoothie made with fruit and yogurt. Following a workout, you want to refuel your body by consuming things such as half of a turkey sandwich, lowfat chocolate milk, or a low calorie sports drink. The most important thing you can do is adequately hydrate your body throughout the day.
