I just found out about this site dietbet.com. Basically you bet a certain amount and you need to lose 4% of your weight in 4 weeks. There are a bunch of different groups to join in and different bet amounts. I just signed up for a contest as I hope it will motivate me. Just wondering if anyone on here has tried it and how much you got paid if you won. The pot I'm in is over $4K but everyone who hits their goal splits the money and the site takes a cut too, so won't be a huge amount(if my math is correct on a $25 bet if half the people hit their goal I'd get about $43), but it's kind of fun to have something to work towards.
