Check out this article to find out what aspects of nutrition are important for endurance athletes.

  1. In general I agree with the overall points, but I disagree on the ranges for how much of our diet carbs, proteins, and fat should be. Carbs seems quite high!

  2. @Kurt Thank you for your comment. Actually, 60-70% is the standard for carbohydrates for endurance athletes.

    See page 128 of:

  3. I didn't mean to say that the article was wrongly quoting the accepted value, just that I slightly disagree with the accepted value.

    The fact that carbs are slated for over 50% of our diet is in part because it is said to be the main source of energy during endurance exercise, but that is not a requirement. Your body is just as capable of burning fat, which may generate a less efficient amount of energy than carbs, but the body stores a TON more of it than it does carbs.

    I would never say carbs are not important. Our bodies certainly need them. However, as a fan of the whole Born to Run argument, I see carbs as something the post-modern world has created a false need for.

    I may very well be wrong, but that's just where my hunch stands at the moment.

  4. @Kurt Thanks for your reply. You brought up a few points that I’d like to address.

    You Said: “The fact that carbs are slated for over 50% of our diet is in part because it is said to be the main source of energy during endurance exercise, but that is not a requirement. “

    My Reply:

    “The reliance on carbohydrate for energy increase with the intensity of aerobic exercise whereas the use of fat tends to decline as the exercise intensity decreases.” (Baechle & Earle, 2004, 107).

    “Adaptations with regard to storage of substrate, primarily glycogen, increase due to aerobic training.” (Baechle & Earle, 2004, 107).

    My Reply:

    “Carbohydrates are metabolic primers, they are needed to completely burn fat. Incomplete combustion of fat will result in ketone bodies. Fat burns in the flame of carbohydrates” (Carbohydrate, 1999).

    “Lack of carbohydrates causes protein to go through gluconeogenesis (conversion of protein to glucose) and be metabolized” (Carbohydrate, 1999)
