Know how much you weigh? The answer may surprise you

scaleMany of us like to think we’re at a healthy weight—or that we’ve always been overweight. According to a new survey of 775,000 adults, Americans tend to underestimate the amount of extra weight they gain. On average, adults gained weight between 2008 and 2009, yet reported weight losses.

When participants were asked what their weight was at the time of the survey and what they weighed a year prior, many people surveyed said they lost weight within that year despite actually gaining weight. Researchers also found that women and younger people were more aware of their weight fluctuations than men and older adults.

With obesity a growing problem for Americans, it’s important to properly track your weight and be aware of gains to help limit the effects that extra weight can have on your body.
