Supersize Vs Superskinny

It's fireworks in the feeding clinic as 24 stone call center agent Julie meets superskinny caffeine addict Jade. Jade weighs just five and a half stone and is desperate to regain her pre-pregnancy size for the sake of her young son. While Jade barely eats a thing, Julie, whose lack of confidence is stopping her from following her dream, binges on platefuls of home-cooked food.

Emotions run high in the feeding clinic as Dr. Christian Jessen pushes calorie-counter Lucy Lee and buffet-binger Leighton Davies to the limit. Lucy weighs in at just under eight stone. She became addicted to dieting after shaking off her post-pregnancy weight and is terrified she'll end up too ill to care for her child.

Emma Frost weighs in at just over 85 pounds and is so obsessed with her healthy diet that she's actually starving herself of the food her body needs; Scott Hastie is a non-stop midnight muncher accustomed to high-calorie meals.

Binge eater Wayne swaps diets with fussy eater Lucia. And Anna Richardson tries tower running, ultrasound and infrared, as she bids to get herself a perfect pair of legs.

Junk food addict Andy moves into the feeding clinic with too-busy-to-eat Hannah, who battles with Andy's junk food medley as she forces down pizzas, burgers, and kebabs. And Anna Richardson tries to get perfectly honed and toned arms.

In the feeding clinic Louise Knox, queen of convenience food, meets Carly Pitman, who's so busy she never finds the time to eat. Louise weighs 18 stone, nine pounds. She gorges on pizza, burgers, fried chicken and chips, and is worried her weight is hampering her chances of a second child, while also leaving her too tired and unfit to play with the one she's got.

Food hater Louise swaps diets with 39-year-old biker Eddie, who needs to change his diet before it's too late. And Anna Richardson gives up on perfection and accepts what she was born with. Food hater Louise Tighe from Hartlepool weighs in at a minuscule six stone 13 pounds. She works long hours as a waitress and barely finds the time to eat.

Dr. Christian invites diet swappers back to the feeding clinic to discover how they are getting on with their healthy new lifestyles. Previously superskinny Gillian entered the feeding clinic with Phillipa to see if she could unlock her dysfunctional relationship with food. Has she been able to do this? It's been a year since full-time working-mum Heather attempted to curb her enormous appetite.
