I actually went on my chocolate diet when I was 14. Here it is:
Breakfast: 3 tasty-cake cupcakes with chocolate icing
Lunch: Lettuce and tomato sandwich with chocolate milk and a large hershey bar.
Dinner: Hamburger, cottage cheese and desert of chocolate pudding
Snack: Chocolate ice cream with whip cream
This worked when I was 14, but I wouldn't do it now
