- I always thought that the body used carbohydrates as its primary source
- of "fuel". It was only when the body depleted its store of glycogen that
- it started burning fatty acids. The byproduct of this process is
- lactic acid, which starts to build up in the muscles...hence the
- pain and discomfort of "hitting the wall". So, drinking caffeine
- wouldn't necessarily conserve the body's carbohydrate supply. But
- if caffeine does increase the fatty acids in the body, then it
- would increase the body's endurance since there would be more
- available "alternative" fuel for the body to burn.
