Many of us have had our excuses at one point or another. It could have been the morning donuts. Or perhaps it was those summer trips -- honestly, who diets on a vacation anyway? But nix those eating and exercise reasons because a small army of scientists have come up with 10 other excuses that could help explain why people are fat.

"Creative" was what one doctor used to describe the report, adding, "At this point, there are no silly ideas." Obviously they're not suggesting you turn off your air conditioning (that one is #3 on the list). These are just potential factors for obesity.

Though some of these are just downright laughable (like the smoking one), you can hardly point a finger at them as being anything more than "excuses." Like any doctor will tell you, the most effective way to combat obesity is (surprise!) dieting and exercise.
