(Newser) – Want to lose some weight? Try eating nothing but McDonald's for 90 days. That's what science teacher John Cisna did, and he not only lost 37 pounds but also saw dramatic improvements in health markers like cholesterol. The Iowa man was inspired to try his experiment after watching Supersize Me, the documentary in which eating McDonald's for a month led Morgan Spurlock to weight gain and worse health. But in Cisna's case, he kept to strict limitations: 2,000 calories per day, while sticking close to the recommended dietary allowances for fat, cholesterol, and nutrients.

Cisna's students constructed their teacher's menu based on those guidelines, and the teacher didn't stick to just salads, oatmeal, and egg whites, although those were included: He typically ate traditional value meals for dinner, and tells KCCI, "I had the Big Macs, the quarter pounders with cheese. I had sundaes, I had ice cream cones." The lesson? "I can eat any food at McDonald's [that] I want" as long as it's balanced out with healthier options the rest of the day. (It probably also helps that Cisna started walking 45 minutes per day during his experiment.) Says Cisna, who made a mini-documentary about the experience, "It's [a] choice. We all have choices. It's our choices that make us fat, not McDonald's." (Amusingly, McDonald's itself recently warned workers that fast-food meals are often unhealthy.)

Great! We are overpopulated as it is, let ignorant/poorly disciplined people shrink their lifespans by 20-50% which allegedly is what the FDA wants since they turn a blind eye to poisons in our food such as aspartame. I'll admit I'm addicted to pizza & burgers but I finally saw the light that meat & dairy are the bad guys in a diet NOT pasta & potatoes like many of these fad diets claim. I have an active lifestyle and am only minimally fat (need to lose 10 pounds). I recently started vegetarian diets on Tuesdays & Thursdays and have lost 3 pounds in less than 2 weeks! It's AMAZING how ignorant young people are....I was in the soda aisle and watched 2 teenagers put a bunch of Pepsi 12-packs in their cart. They had 2 options, regular Pepsi or the Throwback Pepsi with real sugar vs. high fructose corn syrup. They went with the regular Pepsi even though the price and quantity was the same? I should have told them to switch it up, especially to encourage Pepsi to make this a permanent change but I didn't feel like butting in to a stranger's business.

I think he is doing it for an attention. He is a liar, I believe. Since Mcdonald's is not the healthy fast foods at all. Its gross and disgusting taste!
