Our happy hour fact to amaze your drinking buddies with.

Working out doesn't necessarily lead to losing weight.

Researchers are now suggesting that intense bursts of cardiovascular exercise can be counterproductive to weight loss because they also encourage more eating. Not only does working out make people overestimate how much food they can consume, but spending 45 minutes on a treadmill may actually exhaust self-control, which makes it more likely fries will be super-sized even when it's clearly a bad idea.

This new theory is backed by a study on overweight women, and may help explain why obesity and gym membership seem to be rising in lockstep.

So, if the gym is out, how would these naysayers suggest you get rid of the extra pounds? (Drum roll, please.) Eat less.
