I don't think he's 17st either, only because the 'proof' has come from an app where he's input the measurements himself, notice he had the picture of the scales on there yesterday but deleted them today - why? - probably because if he had left it up, people would be expecting him to jump on and show his weight that way (if that makes sense???) - even if he is telling the truth here, I think he's gonna lie about how much he's losing etc.
If he was doing this for the goodness of his health he wouldn't have set a page up where there's a monthly prize at the end, the grabby bastard. I could so see him lying about his size, losses etc to make sure he's the one getting the biggest lot of cash lol
