Exercising without eating first can lead to low blood glucose, which can interfere with your brain function. When you eat, glucose levels in your circulating blood rise and are available to travel to your muscle cells. Glucose is also available as glycogen stored in your muscles.
If you don't eat, you might feel sluggish or lightheaded when you exercise. If you plan to exercise within an hour after breakfast, eat a light breakfast or drink something such as a sports drink. Emphasize carbohydrates for maximum energy. Good breakfast options include: 1  Whole-grain cereals or bread. 2  Low-fat milk. 3  Juice. 4  A banana. 5  Yogurt. 6  A pancake.
