Study offers fat people $3.5K to eat fast food every day

Washington University in St. Louis has the gastronomic deal of the century for fast-food freaks: They can eat to their artery-hardened heart's content all the pizza, tacos and bacon-swathed burgers they can handle every day for three months -- and walk away (assuming they still can) with $3,500. There's a catch, though: They have to be at least 30 pounds overweight to begin with and must gain 5 percent of their body weight during the obesity study, which is being done in hopes of figuring out why some overweight people get diabetes and develop cardiovascular problems while others do not. Along with the monetary benefit, once participants gain the required weight, they'll be entered into a weight-loss program to lose it.
