Protein doesn’t provide plenty of fuel for energy. But you’ll need it to keep your muscles. The typical average person needs 1.2 to 1.4 grams of protein per kilogram of body weight a day. An energy athlete may require as much as 1.7 grams per kilogram of body weight.
Getting a lot of protein can put a strain on your kidneys. Instead of protein supplements, eat high-quality protein, such as lean meats, fish, poultry, nuts, beans, eggs, or milk.
Milk is one of the greatest foods for recovery after an event, because it gives a good balance of protein and carbohydrates. Research shows that whey protein is absorbed quickly, which can help speed recovery just after an event. Milk also has calcium, that is very important to maintaining strong bones.
