I'm using my quest for weight loss to do some good. For every pound that I lose I would ask that you donate a pound of your cash. Rather than me just choosing a charity that may mean nothing to you, I would like to also give you the opportunity to pick a charity and I will donate the money to the top 3 charities chosen over the period of my weight loss. If at any stage I put weight on then for every pound that I do, I will donate £10 into the total pot.
