Dr Christian Jessen's feeding clinic opens its doors for a new series that features new strands highlighting the nation's dysfunctional relationship with food, as well as investigative reports on eating disorders, morbid obesity and extreme eating habits. Experts predict that by 2020 a third of adults in the UK will be obese. But in America this milestone has already been reached. Dr Christian flies out to Evansville, Indiana, officially America's 'Fattest City', where 38% of the population is obese and coffins are the size of hot tubs. The programme also features 18-year-old Ellie Lambert, who discusses how she became anorexic after an operation on her jaw prevented her from eating.
