Ever looked at Google Street view on the internet and seen yourself on the screen? That’s what happened to Bob Mewse, aged 56, although he didn’t recognise the morbidly obese man, with a shirt hanging over his huge stomach as himself – at least not until he made a closer inspection. He weighed 21 stone at the time and was so horrified with his appearance from afar that he decided to change his ways. So he joined a gym, hired a personal trainer, and dramatically altered his diet. Now, a year later he is down to 14 stone and feeling so much better.
