The nutrition needs of athletes are the same, but there are many different ways of satisfying those needs. For example, Muhammed Ali relies on steak for protein, while Bill Walton never touches meat, yet both possess the strength and stamina necessary to perform at the top of their professions. Nutrient needs are obtained from one of 6 groups or combinations thereof. Some misconceptions which have grown around the field of nutrition and exercise are that athletes need extra protein; that extra protein provides extra energy; that carbohydrates are beneficial before competition; that fats are harmful; that water is not extremely important; that extra vitamins impact extra endurance or resistance to disease; and that salt lost through sweat must be replaced immediately. The relationship between food intake and energy expenditure is the focus of the program. Energy balance is assessed for 3 levels of activity--since athletes expend the most energy, they consume the most calories. Each individual must look at his own eating and exercise habits, and learn how to select a diet that keeps the body healthy and fit.
