Pre op 1 week diet - guarantee 1 stone in 1 week??!!

[Frecklefire]

Anyone ever done this diet? Apparently it's given to people when they need to loose weight for an op. There is a lot of eggs and grapefruit on it and you can only do it for a week but apparently if you stick to it you def loose a stone. I know it sounds too good to be true, but my lovely hairdresser says it worked for her. Anyone else on here familiar with it?

Did your hairdresser keep the weight off though? That much weight loss in a week is generally water and some of it will go back on as soon as you start eating more
