Teacher Eats Mc Donald’s For 90 Days[VIDEO]

Mayor McCheese must be so proud!

John Cisna is a high school science teacher from Iowa, who came up with a rather interesting experiment. For three months, Cisna ate nothing but Mc Donald's for breakfast, lunch and dinner and wound up losing 37 pounds in the process.

Surpisingly, he also brought his cholesterol by eating just 2,000 calories a day and even took up walking for 45 minutes each day, but is htis a good example to set for his students?

Mc Donalds was happy to pony up all the food, no doubt excited by all the publicity this stunt would get.
