Hubs was supportive! Though I told him it was $50, not $150. I signed up for a September kickstarter to lose 4% and the Transformer to lose 10% by February. 10% doesn't sound like very much, but 20 lbs sounds like a heck of a lot.
The great thing about the messing around with the scale, full-length mirror, and signage and such is that it has the feel of a commitment ritual.
It should be totally doable to lose 20 lbs by February. In fact, I'm pretty sure that's what I weighed at some point last February. Already I've been to a party this afternoon and didn't eat any of the desserts. win!
