Dr Michael Spira (MB BS MRCS LRCP, Medicine) qualified as a doctor at St Bartholomew's Hospital. After initially specialising in eye surgery, he decided he was far more interested in treating the whole person, not just their eyes. So he became a GP and eventually became senior partner in a large family practice. One day he realised that his weight had crept up and he was a stone (6.5 kg) overweight. He tried to lose weight by following various diets, but nothing seemed to work. Eventually he worked out an approach that did work. It was published as How to Lose Weight Without Really Dieting. Since then Dr Spira has written other diet books and been on several national TV programmes as a diet expert. He has also been adviser to the UK government on an obesity programme, and a member of the Association of the Study of Obesity and the National Obesity Forum. Additionally, he is a medical consultant at a leading group of wellness clinics where advice on diet and lifestyle are key issues.
