3 Months of McDonald’s: A Weight Loss Story


Are you trying to lose weight in the new year? Maybe your best bet is the McDiet. There are now two consumers claiming that they lost weight the McDonald’s (NYSE:MCD) way, and only one of them is the restaurant’s CEO.

When McDonald’s Chief Executive Don Thompson announced in May that he lost 20 pounds in one year without changing his habit of eating McDonald’s “every single day,” it’s safe to say that consumers were skeptical. For one, Thompson is obviously biased, but even beyond that, it’s hard to believe the CEO’s weight loss story is a true one, considering his company is not exactly known for its healthy fare. Big Macs and greasy french fries? Yes. Diet food? No.

That’s why it came as a surprise this weekend when another man credited the McDonald’s diet for his impressive weight loss story. Time reported on science teacher John Cisna on Sunday, saying that he ate nothing but McDonald’s for three months and still lost 37 pounds while watching his cholesterol level drop significantly.

Time reports that Cisna’s students helped him map a plan to implement a 2,000 calorie daily diet regime that consisted only of food sold by McDonald’s. The students paid close attention to daily allowances of nutrients like carbohydrates, proteins, fat calories, and cholesterol — and they made sure their teacher didn’t go over his recommended totals for the day. Talk about a science experiment.
