Let experience be your guide

Remember that the length and intensity of your activity can help you decide how often and what you should eat and drink. For example, you'll need more energy from food to run a marathon than to run or walk a few miles. And try not to add any new products in your diet before a sports event that lasts a long time. It's best to have tried the products before the event to see how your system handles the food.

When it comes to eating and exercise, everyone is different. So notice how you feel during your workout and how your overall performance is affected by what you eat. Let your experience guide you on which pre- and post-exercise eating habits work best for you. Think about keeping a journal to see how your body reacts to meals and snacks so that you can change your diet for your best performance.
