A high school science teacher took on the challenge of following a strict McDonald’s diet for 90 days. The catch? He could consume only 2,000 calories a day and had to stay within the FDA’s recommended daily intake of nutrients.
John Cisna, 56, lost 37 pounds within the first three months of trying out the McDonald’s diet.
According to NYDailyNews, Cisna came up with the idea when he challenged several of his students interested in entering the medical field to an intriguing science experiment.

He came up with this hypothesis: “Is it possible for a person to become better off eating nothing but McDonald's for breakfast, lunch and dinner for 90 days?"
From there, Cisna’s students created 56 different combinations of McDonald’s meals that stayed within 2,000 calories and met FDA guidelines for daily allowances of fat, sugar, protein, carbohydrates and other nutrients.
Cisna also added exercise to his weekly routine, walking 45 minutes a day, four to five times a week.
The results spoke for themselves: Not only did Cisna lose 37 pounds in the first 90 days, but his cholesterol also decreased from 249 to 170.
Given this positive experience, Cisna decided to keep going for another 90 days.
In total, Cisna lost more than 60 pounds. Dropping from 280 pounds to 219, he proved that finding healthy options at fast-food restaurants is possible.
Today, the science teacher is an official brand ambassador for McDonald's, ABC News reports. He travels the world sharing his experience and teaching people how to make conscious decisions about what to eat.
Cisna explains that his talks are not about encouraging everyone to try an all fast-food diet.
“I want people to know this was nothing more than an experiment," he told NYDailyNews. "I’m not pushing McDonald’s. I’m not pushing fast food. I’m pushing taking accountability and making the right choice for you individually.”
Cisna now has his own mini-documentary, “540 Meals: Choices Make the Difference,” and a book, “My McDonald’s Diet.”
