"Jon has blown my theories out of the water and pointed me in the right direction, in terms of correct diet and methods of exercise. But the best thing is that it is all sustainable. I'm eating different, healthier foods, as well as some that I've always eaten and enjoyed and not going hungry. But it's not all good news. On the down side I've had to go buy new trousers (32" waist for the first time since I can remember) and new t-shirts. Oh well!" Carl Hainsworth, Leeds
