Olympic gold medalist Michael Phelps also took gold on Google, where his eating plan was the No. 1 most-searched diet term. Phelps reportedly consumes a whopping 12,000 calories each day (apparently a typical breakfast for him includes an egg sandwich, pancakes, a five-egg omelet, grits, and French toast), and while his six-pack clearly can handle the load, it's best to avoid this diet plan unless, of course, you are Michael Phelps.
