Wacky and amusing diet story of the week:

In the 1970's, Robert Linn, M.D., prescribed a program called the Last Chance Diet, on which people ate nothing but a liquid protein drink consisting of collagen. Ingredients included pre-digested animal hides, tendons and slaughterhouse byproducts combined with sweeteners and artificial flavors. Each drink contains less than 400 calories per serving making this a starvation type diet. His book sold over 2 million copies. The FDA stepped in after several Last Chance dieters died- some of heart attacks.
