McDonald’s-Only Diet Helps High School Teacher Lose Nearly 40 Lbs.

High school teacher John Cisna has lost 37 lbs. over the course of 3 months in the least-likely way imaginable: eating a diet consisting only of food from McDonald’s.

Just what the world needs, a fast-food enabler.

As TODAY reminds us, the last time we heard a story about someone subjecting themselves to a diet of all McDonald’s, all the time, it was filmmaker Morgan Spurlock as part of his Super Size Me documentary (the title of which was prophetic). Cisna made his own amateur documentary to put the idea out that choice does exist.

Here’s the catch: Cisna is following a 2,000-calorie McDonald’s diet and exercising daily, part of a plan he devised with his students at Colo-Nesco High School, in Colo, Iowa (how does this McDonald’s idea not completely destroy his authority in a biology/health setting?). Prior to undergoing the McDonald’s diet regimen, Cisna was 280 lbs. with a six-foot frame, putting his body mass index (BMI) in the “obese” category at 38.

“If I had gotten any bigger, I’d probably have to avoid harpoons,” Cisna told TODAY’s Savannah Guthrie and Matt Lauer on Monday.

Bear in mind, in the wake of Spurlock’s 2004 film, portraying his own McDonald’s diet, the fast food franchise’s menu has changed significantly. Cisna is able to enjoy Caesar salads and egg white breakfast items with the goal of losing weight instead of purposely poisoning filling himself with the most unhealthy McDonald’s items possible. But he didn’t just stick to the lighter fare.

“I had the Big Macs, the quarter pounders with cheese. I had sundaes, I had ice cream cones,” Cisna told Hearst Television affiliate KCCI.

“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,” Cisna said.

After approaching the local McDonald’s franchise owner about his diet and documentary idea, Cisna got the 90 days’ worth of food on the house.

“The point behind this documentary is, ‘Hey, it’s choice. We all have choices. It’s our choices that make us fat not McDonald’s,'” he said.

What do you think of Cisna’s all-McDonald’s diet? Do you think his message will be lost on McDonald’s patrons? Is illustrating such a diet responsible?
