Furious Pete is a competitive eater, and frankly is impressive in his sport. He posts a new video every Wednesday consuming an amazing amount of whatever is on the menu for the day.  He also has a body that looks like he spends the rest of his day at the gym.  In this particular video, he demonstrates how some ads do a "before" and "after" set of photos to sell a supplement or a fitness product.  Part of his secret is to shoot the "after" shot first, and then get  bloated for the "before" shot.  In this video, he says there's a five hour difference between photos.  And now you know how to do your own.
