I completely agree that a low carb diet is NOT the way to go, ESPECIALLY for cyclists. But what about carb depletion for 48-72 hour periods, short periods. Bodybuilders and many professional cyclists have done this during the off season to get rid of all the junk carbs they've taken in and to kick start their metabolism again. This also give you the chance to get "healthy" carbs back into your system. I've been following up on this and it seems to work pretty well as long as it is not a long term situation, but only TEMPORARY.
