This sounds too good to be true, so it probably is. But scientists think they may have found the secret to "weight loss in a pill."

Apparently all this excitement is due to a drug that has been developed that revs up the metabolism in mice, much the same as physical activity would. The mice are able to eat as much of a high-fat, high-calorie diet as they want and they don't gain weight.

Now what works in mice doesn't always work in people (so I wouldn't get your hopes up), and that doesn't even consider possible side-effects and health complications something like this might cause. And I'm wondering: if this revs up the body as if it were working out, does that mean I'll be sitting on my couch breathing heavy and sweating profusely while watching TV? Ugh, no thanks.
