A number of overweight Americans are giving up in their battle of the bulge.

Nearly a third of the obese respondents in a new poll from the Centers for Disease Control and Prevention admit they've tossed in the towel, and are no longer following a diet, exercising or taking any active steps to shed pounds.

The defeatist attitude stems in part from a lack of success. More than 40% of those who tried to lose weight this year say their efforts yielded negligible results. And few are interested in taking the surgical route to meet their weight-loss goals. Nearly 60% consider gastric bypass surgery to be a risky procedure.

However, an overwhelming majority also know they shouldn't give up. More than 95% recognize their overall health will improve even if they only drop a small amount of weight.
