Man Loses More Than 30 Pounds on McDonald's Diet

Cholesterol level also drops

Remember the 2004 documentary Super Size Me and its blatant lack of a twist ending? Guy eats only highly processed, high-fat McDonald's food for one month. Guy's health deteriorates. The end.

Science teacher John Cisna tried out a similar experiment, but saw drastically different results. After eating nothing but McDonald's for three months, the Iowa man lost 37 pounds and saw his cholesterol level drop significantly, local TV station KCCI reports.

Cisna enlisted his students to help him plan out a 2,000-calorie daily diet plan consisting only of food sold by the fast food giant. They also tried not to exceed recommended allowances of nutrients like carbohydrates, proteins, fat calories and cholesterol.
