After eating only McDonald’s for three months, Iowa science teacher John Cisna lost 37 pounds and saw his cholesterol level drop significantly.
No, this wasn’t another documentary experiment like 2004’s Super Size Me – it was a school science experiment.
The 207 pound science teacher ate a 2,000-calorie daily diet designed by his students. The diet aimed to stay within recommended allowances of nutrients like carbohydrates and fat calories.
He also walked 45 minutes daily during the course of his experiment.
Cisna said, "so this isn't something where you say, 'well he went to McDonalds and he only had the salads.' No, I had the Big Macs, the quarter pounders with cheese. I had sundaes, I had ice cream cones."
A typical day's sustenance varied, but it would typically include two egg white delight McMuffins, a bowl of maple oatmeal, and a 1% milk for breakfast; a salad for lunch; and a value meal for dinner.
“It’s our choices that make us fat,” Cisna told local TV station KCCI. “Not McDonald’s.”
