Washington University is conducting a study on obesity and is asking participants to gain weight.
As a part of the study on obesity, the school is offering participants the opportunity to eat all the fast food they want every day for three months. They'll even get paid $3,500 for it.
The only catch? They have to gain five percent of their body weight during the duration of the study.
The point of the study is to determine why some overweight people develop diabetes and other cardiovascular risk factors, while others do not.
The restaurants participating? McDonald's, Taco Bell, KFC, Burger King, and Pizza Hut.
