The 2004 documentary Supersize Me featured a man who only ate McDonald’s for a month. The results he reported in film were less than appetizing, and he claimed his health deteriorated significantly. After viewing that documentary, John Cisna of Ankeny — who is also a science teacher in the Colo-Nesco School District — put together his own amateur documentary looking at the fast-food giant. He and his team of students came to a much different conclusion. “I can eat any food at McDonald’s (that) I want as long as I’m smart for the rest of the day with what I balance it out with,” Cisna said. That was the theory science teacher Cisna laid out for three of his students at Colo-Nesco High School this past fall. Ninety days of Mickey D’s for breakfast, lunch and dinner, but with strict daily nutritional limitations of 2,000 calories and trying to stay close to the recommended dietary allowances for nutrients like carbohydrates, proteins, fat calories, cholesterol.
