I can't speak for anyone else, but I really feel like I'm on death's door if I don't eat anything every six hours. My entire body breaks down, my muscles get sore, and a migraine develops. As long as you are constantly active, give your body the nutrients it requires. Science has already proven that there are many more negative connotations to this entire deprivation of nutrients. Don't deprive yourself of what its like to be alive and well.
