This week's show features Charlotte, whose dreams of being a pin-up model have fallen flat so far due to her desperate diet. She weighs just six stone and her childlike portions are doing nothing to help her gain the womanly curves she craves.
Joining her in the final five-day diet swap is 22-year-old Heather, who's passing on her terrible eating habits to her toddler daughter. The bride-to-be's reliance on ready meals is keeping her at over 20 stone - and no closer to getting into her perfect wedding dress.
Three weeks after two thirds of her stomach was cut away in life-threatening surgery, Lisa Wheeler reveals her dramatic weight loss.
Ditching diets in favour of a glamorous photo shoot, Anna Richardson discovers the Hollywood cheat's route to a slimmer body, including inch-reducing designer frocks and digital liposuction.

While, at the end of their course of therapy, four anorexia sufferers describe their feelings as they visit a spa for a massage and face their biggest challenge of the course.
