Create a continuing weight loss bet
The bet concept is working well for me, and I would like to repeat the process after this six-month period is finished. I could just start a new DietBet 10 round, but that doesn't seem like a good idea. The DietBet 10 is clearly geared to people who are just starting to lose weight and therefore will drop a lot of water weight quickly at the beginning.
It would be nice to have a continuing weight loss bet that you could "graduate" to at the end of the six month period. I would structure it such that your starting weight was the end weight from the previous bet, and your goal was to lose perhaps 1.5% per month for six months.
