During many Olympics, Usain Bolt sustained himself on nothing but 100 Chicken McNuggets a day, because they have a really optimal Carb to Protein ratio and are very consistent (whereas strange new food in foreign countries might be risky).
So, you're just eating like one of the world's best athletes.
Something tells me he was also getting fiber, vitamins, and minerals from somewhere during that time, so unless you have a dietician on call to help you balance that out, don't eat nothing but Chicken McNuggets.
