Protein, carbohydrate, and lipid intake and oxidation in healthy young men on a control day with isocaloric energy intake and on 9th day of a 1,000 kcal/day excess energy intake (hypercaloric condition). Data show that protein and carbohydrate balances are achieved in both conditions, whereas fat balance is only present in isocaloric condition. In hypercaloric condition, fat oxidation is inhibited and a large lipid storage is demonstrated.
