Just finished My first challenge. A kickstarter to lose 4%.. and I met the goal. Betting on yourself can be a great way to lose weight! I think the higher entry fee also helped. I'd sure hate to lose that 100 bucks! Plus I have personally dedicated my entry fee's and winnings to go to dog rescue charity's. So not only am I doing it for Me.. I am also doing it for all those amazing dogs out there.
