I created a DietBet for Hellobee members! (But anyone can join).
It starts March 1 and you bet $25 that you will lose 4% of your body weight in 4 weeks. If you lose the weight, you split the pot with everyone else that met that goal.

The more people that join, the larger the bet! Let me know if you have questions!
