Interesting that it could be slow, I'm in week four and not noticed any difference yet. Mind you I only weighed myself for the first time in years at the weekend, so am only now starting to track weight. I don't care what I weigh, its purely about body shape really.
I'm petite and currently weigh about 5lb above what I'd like to be. I basically have more fat around my tummy and bum/thighs than id like. Has anyone of a low starting weight had success on 5:2 or is it unlikely to do the job?
