A Brief History of Extreme Diets
Tapeworms, cotton balls, and cigarettes—not exactly the breakfast of champions, but at one point these (and a dozen other items) were featured ingredients in the craziest diet menus of all time.

2003 The 7-Day Color Diet:
Devotees eat fruits and vegetables of a specific color for a full week. By the last day, your body learns to crave regular servings of fruits and veggies, which helps with longterm weight-loss goals. Basically, you're going vegan.
2004 The Spoonlight Program:
Made famous by Karl Lagerfeld and his physician, this low-carb, low-fat, low-calorie diet promoted plenty of sugar-free soda and little exercise.
2007 Reverse Diet:
By reversing the order in which you consume the bulk of your calories (dinner for breakfast, lunch is lunch, breakfast for dinner), supporters believe it will change the way your body converts food into energy.
