I never thought to actually explain in detail what a DietBet is. DietBet is a website/app dedicated to encouraging people to lose weight by betting money on their personal success at doing so. There are two main types: Kickstarter and Transformers.
The Kickstarter is a 4-week ‘game’. You take your initial weight-in pictures and once they are approved you’re ready to go. You have 4 weeks to lose 4% of your starting body weight. Bets start at $35, however some games might have higher bets. If you are a member, you can submit your unofficial weigh-in every week to be put into a drawing for various prizes that DietBet gives away. Once that game ends, you have about 48 hours to submit your final weigh-in and have it approved. If you win, the pot is split amongst you and the other winners, with DietBet taking out a small percentage of the total pot before distribution. If you win, you always get at least the money you bet back, and a little more (depending on how many people won).
The Transformer is a 6-month game. Yup. But rather than 4% every month for 6 months, the goal is to lose 10% of your body weight by the end of your 6th month. 3% for month 1, 6% by month 2, 8% by month 3, 9% by month 4, 10% in month 5, and 10% in month 6. It works much like the Kickstarter, however the pot is split between the monthly goals and the final round, with the final round having most of the pot. To qualify for the final round, you need to have lost at least 6% of your initial weight by the time Round 6 starts. So you do not have to win every round, every month during the 6 months. And the rounds you do win will be paid out at the end of the 6-month game.
What about cheating?
The DietBet system has it’s own authentication system. For your weigh-ins, you are prompted to submit 2 pictures (only for DietBet use). The first is of the scale (with you standing on it-feet only). The second is a full body picture of you standing on the same scale. Once those pictures are submitted, a person will review the pictures and approve them (or reject them if something seems fishy). That doesn’t mean it is impossible to cheat the system, but you can’t control everyone right? And in the end the only person they’d be cheating is themselves. In cases of big bets or fishiness, DietBet may require a video submission of your weigh-in.
Is this healthy?
No one wants to lose their money, which is precisely why DietBet has come to its current popularity and effectiveness. It’s one thing to tell yourself you’re going to lose 7 pounds this month. It’s another thing to bet $35 that you will lose 7 pounds this month. It’s also rewarding to know the effort paid off (and paid back) when you win the DietBet and get your $35 back plus a little extra. However, what if you’re trying to lose the weight and it’s not coming off? Then you start panicking because you don’t want to lose the money you bet. What if you joined a $100 bet because you thought you could do it, and now you’re not so sure? You might be tempted to turn to some rather unhealthy measures to lose the weight. DietBet does try to stem this behavior. If they deem your level of weight loss unhealthy, they will not reward that with a win. They have a system set in place of how much weigh loss is too unhealthy in a month. For the kickstarter, that is more than 12% of your initial weight. For the Transformer it’s 12% (R1), 18% (R2), 24% (R3), 27% (R4), 30% (R5 & R6) of your initial weight.
Is it good?
DietBet boasts that 96% of their players lose weight and the science behind behavioral change and motivation is what drives the purpose of DietBet and leads to their players’ successes. Also, many people who have tried DietBet love it because of the community. As you play in the game, you can not only typically win prizes in game, but both give and receive encouragement from fellow players of the same game! You’re not competing against each other but rather trying to help each other reach your goals. I think DietBet can be a really great thing, depending on your personality and drive. I personally like the 6 month Transformer more because I personally find it hard to not lose steam after a few months, and this is just the kick in the rear I need. The Kickstarters are a little intense for me though, I hate stepping on the scale searching for that one number in such a crunched time period; it makes me feel anxious and unhappy. DietBet is starting to venture out into other options though. They’ve started making more varieties such as Flexible Kickstarters that give you up to 6 weeks to lose 4%, StepBets, RunningBets, Workout Challenges, MealPrep challenges and more.
