Our happy hour fact to amaze your drinking buddies with.

Most obese Americans underestimate how fat they are.

A Harris Interactive / HealthDay survey asked 2,418 adults their height and weight, as well as if they thought they were of normal weight, overweight, obese or morbidly obese.

It turned out 30 percent of overweight people believe they are of normal size, 70 percent of obese people think they are just overweight and 39 percent of morbidly obese people classify themselves as being only overweight.

"While there are some people who have body images in line with their actual BMI [body mass index], for many people they are not, and this may be where part of the problem lies," said Regina Corso, vice president of Harris Poll Solutions.

We blame the glossy magazines. If they were doing a better job of airbrushing our celebrities to even more unrealistically skinny dimensions, maybe this wouldn't be such a problem.
