If you want a smaller waistline, then it's time to keep your food enemies close. In fact, the closer the better.

I used to think that living next to a fast food restaurant or a grocery store would be dangerous to my health. But, it's actually not true at all.

In fact, it is just the opposite. According to a recent study in the American Journal of Public Health, people who live less than a half mile from any source of food including grocery and convenience stores are less likely to become obese.

"People who lived near a wide variety of food stores and restaurants "were 10 percent less likely to become obese."

The study shows that cities are making a mistake when they ban fast food outlets from neighborhoods, say researchers. Instead, each neighborhood should have a wide range of food outlets, including full service restaurants and grocery stores that promote healthy fare.
