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.
A lot of factors can contribute to why you may feel ill during exercise. The first things to check are nutrition, hydration and energy levels. Nutrition: do you have fuel in the tank? A lot of exercisers think youâre supposed to work out on an empty stomach and this isnât true. So if you go into a workout with no fuel on board, this can possibly cause you to feel bad and perform poorly. Did you eat TOO much before a workout? The opposite can be true sometimes as well.
