If you're struggling to lose weight, it might be because you're going at it alone. It might also be because you've tried before and saw yourself go up and down, so it's hard to find concrete motivation to make this the time that the weight actually comes off. If you want to give a real, valiant effort and motivate yourself to lose weight and get healthy, you might want to put your money where your mouth is and give DietBet a try.

It's not a weight loss program, it's not a meal delivery solution, and it's not a magic pill. DietBet is a website that makes you put a little bit of money, usually around $20, into a pot and bet that amount on your ability to lose 4 percent of your body weight in four weeks. The money goes into a collective pool of other dieters looking to do the same. Those of you who actually lose the weight split the pool of money. You lose weight and make extra cash. If you don't meet your goal, you're out $20 but you can try again whenever you want.

You can join a "game" that's about to start, or start your own with a group of friends. You can post on the game's page with tips, recipes and questions that your weight loss community can chime in on. Celebrities like Sean Kingston and Jillian Michaels have joined in and have created their own games that draw hundreds of people to band together and try to lose weight.

The website was inspired by an office diet bet, says founder Jamie Rosen, according to Forbes.

"I saw how effective it was at motivating them. That was just the spark - it actually took several years to evolve into the social dieting platform that we've built today," he explained. A group trying to lose weight together are much more likely to succeed, as explained on Reader's Digest, and if you have money on the line - even just $20 - you'll push yourself more. If you do well, you can win your money back and much more. DietBet lets you bet on your own willpower and push you to a healthier life.
