About this programme

3/11. Julie Menzies, 42, is an award-winning baker, but her love of all things fatty and sugary has seen her balloon to almost 24 stone, while at the other end of the scale is 24-year-old fashion manager and fussy eater Zoe Hughes-Blinston. In an emotional diet swap, Julie is horrified by the medical implications of her dining habits and Zoe talks about being bullied at school because of her slight frame. Plus, Emma Woolf investigates eating disorders among men, while in McAllen, Texas - one of America's fattest towns - Dr Christian Jessen finds out how the funeral parlour and crematorium deal with bigger and bigger bodies.
