Now this is what I call a dream diet. John Cisna, a school teacher from Iowa, ate only at McDonald’s for three whole months and managed to lose 37 pounds (16 kilograms)! He even made a short documentary on his experiences.
John’s project was inspired by the 2004 documentary film, Supersize Me. It featured an American filmmaker, Morgan Spurlock, who also ate only McDonald’s food for 30 days. At the end of that period, Spurlock reported a drastic deterioration of his physical and psychological health. Which is why John’s findings are almost unbelievable. In spite of eating for a longer period of time at the fast food chain, he reported better health and weight loss. In fact, there has been a large improvement in his blood cholesterol after the three-month period.
How could it be that two experiments, so similar to each other, reported such different results? Simple. John followed a much smarter plan that Spurlock did. John and his team of students formulated a plan that would allow him to eat fast food and still stay healthy. “I can eat any food at McDonald’s I want as long as I’m smart for the rest of the day with what I balance it out with,” he said.
