In a way us low carb types have an advantage since we eat mostly fat. I only short tour and don't cook....last one was 500 miles in 7 days. I ate 2 pounds of nuts, 3 of cheese, and a ton of pork when I finally hooked up for part of RAGBRAI.

It took me a couple of years of convincing self to eat to live, not live to eat.

YMMV
