About this programme

2/4. Dr Christian Jessen meets a woman whose excessive eating has left her with a huge growth on her leg that weighs the same as a small child. She is now so dangerously obese she is running out of options to save her life. Dr Pixie McKenna helps a woman who wheels around her kitchen on an office chair because her joints and circulation cannot take her 33st, while the pumped-up portable pod is taken to Glasgow to tackle its growing obesity problem and launch a campaign to get the nation off their bottoms. Dawn and a volunteer check in at University Hospital in Coventry, where they are locked away for a 24-hour experiment in which all her bodily functions are monitored to find out how fat works and its effect on the human body.
