Athletes' diets are predictably healthy and pristine, except for the whole part where they are not.
Some do go whole ham on the uber diet trail. They eat how we expect professional sports figures eat. Their meals are laid out by the ounce, their caloric intake measured down to the last responsibly sourced halibut fillet.
