According to ACE's standards, it is normal for female athletes to have between 14 and 20 percent body fat, for fit women to fall between 21 and 24 percent and for average women to have between 25 and 31 percent body fat.
About 10 to 15 percent of an athlete's total calories should come from protein, with the remaining calories coming from carbohydrates and fat. Athletes who consume diets adequate in both these nutrients end up using less protein for energy than those who consume a higher protein diet. This means that protein can go toward building and maintaining lean body mass. Athletes need to ensure that they are also meeting needs for carbs and fat, not just protein.
