Foodaholic Rob Gillett goes head to head with foodphobic Hayley Payne in the Feeding Clinic. And Dr Christian goes for a ride on a supersize ambulance in America's fattest town. Rob Gillett's obsession with donuts and cream cakes has seen him eat his way to an enormous 35 stone 10 pounds . While on the other end of the scale, for busy-bee Hayley food isn't a priority - which has left her weighing in at just 6 stone 12 pounds. And the warning signs of bulimia are revealed through the eyes of 20-year-old Lucy Glover, who regularly binges and purges on a staggering 8000 calories at a time.
