He says he has a psychological compulsion to overeat. As a result of Guys weight, he also suffers from sleep apnoea, a condition that stops his breathing when hes asleep. Guy has spent years trying to diet and has sometimes been successful. He achieved a weight watchers plaque when he was 37, for losing 8st and managing to get down to 13st.
