Your body needs fluid intake and food intake when you exercise if not it results in loss of fat free mass and it increases dehydration risk. The article states years or research says that a diet high in complex carbohydrate, moderate in protein, and relativity low in fat is best for both health and physical activity. Weight loss, weight gain, and weight stability are a matter of energy balance. It also states that you should consider that the weight of fat is not the same as the proportion of fat. Carbohydrates 7 to 8 g/kg body weight per day. Complex carbohydrates rather than sugars are preferred sources. Protein in adult’s 1-2g/kg body weight per day.
