Being an athlete is not all exercise. It is said that losing weight/gaining muscle is about 25% exercise and 75% diet. Diet is important for building muscle and fueling your body properly to avoid feeling sick or light-headed. Protein is strongly recommended to make you feel more full after a workout so you do not overeat, but still keep energy. Carbs are also the body’s main source of energy. Basically, our bodies cannot function without replenishing what we lost during our workouts! For all the healthy eating tips while exercising, click on the link below.
