I agree with Mandy, frankly blogging, staying committed, etc.............has showed we are all winners. I told Steph when we first started if I won I wasn't going to take the money anyways.
I think it should percentage, usually that is how it goes. So what your original weight was, what your end weight is and what percentage you lost overall. That would be the most fair and is how the biggest loser does it. Thoughts?
