The show revisits three of last year's feeding clinic inmates - meal dodger Nathan Smith, takeaway king Chris Longley, and convenience queen Jo Palmer. One year on, have they managed to ditch their dreadful diets for good? Plus, it revisits Dr Christian's time in Evansville, Indiana - the US city that topped the polls in 2011 as America's Fattest. At the local Deaconess Hospital, he meets patients suffering the severe effects of obesity, and staff on the front line dealing with the crisis.He also visits Keith Davis from Goliath Caskets, who knows all about the ever expanding population - because he makes the biggest coffins in the United States. Twenty-four stone 6 Chris gorged on up to a dozen takeaways a week. His body was paying a very high price when he checked in to the Feeding clinic. Sharing the diet swap dinner table with Chris was 21 year old meal dodging hairdresser Nathan Smith - who had a head full of excuses for his puny 8 stone 5 frame.
