McDonald's 'Diet'? Teacher Claims He Lost 37 Pounds from Eating Fast Food (Video)

Of course, we've all heard of fad diets. There's that one where all you eat is cabbage soup. The three-day water cleanse. The tuna diet. In fact, if you Google whatever word in your search engine with the word "diet" behind it, there's probably some sort of diet out there.

But just when we thought diets couldn't get any crazier or unhealthier (and I'm not talking about the kind of unhealthy where you starve yourself-that's the cardinal code of fad diets) welcome to the McDonald's diet. Don't believe me? Well, just ask science teacher John Cisna, who allegedly lost 37 pounds over three months of only eating a 2,000-calorie-a-day diet of fast food.

Wait a minute. Isn't eating fast food bad for you? For instance, remember the 2004 documentary "Super Size Me," where that guy eats only highly processed McDonald's fast food for a month and his health, for lack of a better word, deteriorates.

Well not only did Cisna see his weight drop, but according to the local TV station KCCI, he also saw his cholesterol drop significantly, too. (What?)

Well, here's the catch. With a little help from his students, Cisna planned a a 2,000-calorie diet plan that did not exceed the recommended daily allowances of carbohydrates, fat calories, cholesterol and proteins while still only eating at Mickey D's, according to the New York Daily News.

For instance, at breakfast, Cisna might have two egg white delights along with a bowl of maple oatmeal and 1 percent milk, according to Time. Lunch might include a salad, while dinner would include a more traditional fast food item, such as a cheeseburger and sundae.

According to the news organization, when Cisna told the owner of a local franchise about his experiment, he agreed to provide all of his items for free over the three-month period.

But wait a minute. Eating a 2,000-calorie-diet-a-day alone of McDonald's might not be enough to make you lose weight. To be fair, Cisna also made sure to exercise daily, for approximately 45 minutes.

At the end of it all, he went from 249 pounds to 170 pounds.

 "It's our choices that make us fat," Cisna said, via KCCI. "Not McDonald's."

That certainly may be true. However, many studies have also shown that McDonald's and other fast food chains alike are not just unhealthy for their high caloric intake but for the food additives and preservatives that may be found in products. 

In conclusion, when it comes to eating fast food, a little's ok, of course. Even we have to admit, this stuff tastes good! Would we recommend eating it over a long period of time even if you could lose weight? Probably not.
