I know several of you have new bikes as an incentive for losing a given amount of weight. One of the NHS (National Health Service) trusts over here has started offering actual money for sustained weight loss for a trial period: http://www.nhsweightlosstrial.com
Conveniently, it's the one that covers the area in which I live...
The amounts offered are dependent on the actual amount lost and how long you can keep it off, but seem pretty generous - if I can lose the 50lbs I've been aiming to lose this year anyway and keep it off for 6 months, I get paid £425 (about $600).
There's been a fair bit of negative press over this trial, but I figure if the cash is being given away anyway for something I'm planning on doing anyway, it'd be silly not to take them up on the offer..
If I succeed, I'm planning on spending the cash on a new bike, naturally.
Would cold hard cash encourage any of you lot to lose weight and keep it off?
