Frustrated by her husband's lack of motivation, Angela Wornick of NY challenged him to see who could lose weight the fastest as part of a New Year's resolution. As a result of the bet, husband James shed an amazing 191 pounds over the span of 10 months. It was a losing bet of the very best kind.

At his heaviest, James tipped the scales at 366 pounds. But now, thanks to a strict diet and exercise regimen, he weighs in at a svelte 175. Now that's a bet with a *serious* payoff.

Watch James' incredible weight loss story below.
