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 exercise in the morning, get up early enough to finish breakfast at least one hour before your workout. Be well-fueled going into a workout. Studies suggest eating or drinking carbohydrates before exercise can improve workout performance and may allow you to work out for a longer duration or higher intensity. If you don't eat, you might feel sluggish or lightheaded when you exercise.
