  • Most additional calories should come from carbohydrate.
  • Some may come from protein foods, but excess high-protein foods can lead to a decrease in glycogen stores.
  • Heart-healthy foods can also be consumed.
  • Some protein is good, but it is often far less than most athletes think.
  • Athletes who consume low-protein diets can benefit from protein supplementation.
    • Whole foods, however, should remain the focus.
    • Overemphasizing protein intake can lead to inadequate carbohydrate intake and excess caloric intake.
