A riding buddy of mine went on Adkins and was losing weight. However it really messed up his riding. He usually was a much stronger rider than I, but while doing Adkins, he was slower. On one ride he basically bonked at the 30 mile mark. We all but forced him to drink a quart of Gatorade and within minutes he was close to his old self. You might want to 'cheat' a little when out on long rides or other activities.
