I am hosting a DietBet. If you bet $15 on February 16th and lose 4% of your starting body weight by March 16th, you will get to split the pot with the other lucky winners - and you can donate a portion of your winnings to charity. I'll be giving at least 25% of my winnings to the Humane Society.
You can join in the fun here!
I'm not getting comped for my promotion of DietBet. I did participate in one (I forget whose! Sorry!) towards the end of contest prep and wound up doubling my investment. It was great motivation! So I'm using it again =) I stick to what's simple -- and what works.
I'll be posting my best tips, tricks, and motivators for participants every day - and I'm sure others will chime in! Join us! =)
