NUTRIENTS FOR THE ATHLETE: FAT

Fats, like carbohydrates, are used by the body for fuel and are essential for the absorption of certain vitamins. The most important role of fat is to spare carbohydrates (which are in limited supply) in exercise of long duration and low intensity.

Fat is a valuable metabolic fuel for muscle activity. Endurance training significantly increases the ability of muscle to utilize fat. During aerobic exercise, fat serves as the preferred fuel source for muscle activity, however, this relationship is not necessarily enhanced by increasing the dietary intake of fat. The endogenous body fat stores are more than adequate to meet these needs. Even the leanest athletes have sufficient fat storage to meet the metabolic demands of strenuous exercise.

Consuming a high-fat diet will result in a larger proportion of fats used during exercise, but this limits the amount of carbohydrate storage, which ultimately limits endurance.

Therefore high dietary fat intakes should be avoided. Also too much fat can lead to heart disease, obesity, cancer and other health problems. Fat intake for athletes, as well as healthy adults, should comprise less than 30% of total calories. Fats in the diet may be of animal or vegetable origin. Selecting lean meats, nonfat or low fat dairy products and limiting added fats such as butter, margarine, salad dressing, cream sauces, gravies and fried foods will help you achieve this goal.
