You may have read or heard about the high school science teacher, John Cisna, from Iowa who had three of his students do a semester project featuring him eating nothing but food from McDonalds for 90 days.  The purpose of this experiment was to see if he could lose weight and how it would affect his health. In September 2013, John Cisna, who was obese weighing 280 pounds, wanted to see if it was possible to eat only fast food, yet by controlling his calorie level and balancing nutrients, could he actually lose weight in the process.  What he found out was a resounding “yes.”
