Most people agree that the U.S. is facing an obesity epidemic, but the majority of Americans don't think they're part of the problem.

That's according to the "Weight of the Union," a 2014 survey of 1,000 adults conducted by market research company Research Now for Anytime Fitness. The report found that 84 percent of respondents believed that Americans generally weigh more than they did five years ago -- which is true, according to a 2011 Gallup poll.

What Americans didn't want to admit, however, is how much they personally contribute to the national waistline. The majority of overweight respondents (56 percent) and 30 percent of obese respondents said they felt their weight was "normal" compared to the general public. The delusion disappeared, however, when respondents were asked to compare themselves to their friends and family. Compared to family, 54 percent of people with an obese BMI felt overweight, while 31 percent of people with an overweight BMI felt like they weighed too much.
