This story has been all over the Internet the past few days: “man eats only McDonald’s for 90 days and has surprising results”. ARE YOU KIDDING ME??? What exactly is surprising about an overweight man who starts to restrict calories and adds exercise to his daily routine losing weight? This is not a shocking result. Of course he lost weight. He even made an effort to meet his daily nutrient requirements by eating things like egg whites and oatmeal for breakfast and a salad for lunch. But even if he hadn’t met nutrient requirements he would have lost weight by consuming fewer calories than he expended.
Remember that professor who went on a Twinkie diet a few years back? He lost 27 pounds in two months by restricting calories and eating only snack cakes and other “junk” food most of the time. Apparently he did eat vegetables when eating with his family so that’s likely how he managed to stave off scurvy.
It seems that people are interpreting the results of the current experiment to indicate that Morgan Spurlock’s Supersize Me documentary was some sort of hoax. The truth of the matter is that you can gain weight eating McDonald’s and you can lose weight eating McDonald’s. And just by losing weight doesn’t necessarily mean that you’re healthy. A diet high in vegetables and fibre is important to protect against many diseases chronic such as cancer and dementia. A simple drop in weight and LDL doesn’t mean that you’re healthy or that you’re going to stay healthy in the long-term.
I also can’t resist pointing out that McDonald’s provided the man with free food for the duration of his experiment. Wasn’t that generous of them? Providing a man with free food for a month in exchange for a huge amount of positive publicity. Kind of makes you wonder how a grade school teacher managed to garner so much publicity for his “personal” experiment and little documentary.
