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 ... (more)is hampering her chances of a second child, while also leaving her too tired and unfit to play with the one she's got. Louise receives a shocking video postcard from America, in the form of Laurie who weighs in at a staggering 30 stone, and can't stand up for more than two minutes at a time. Carly, meanwhile, is a tiny seven stone, and consumes a fraction of the vitamins and minerals her body needs. She never finishes a meal and is constantly tired as her body struggles to run on empty. Dr Christian warns Carly that this sort of behaviour, if unchecked, can spiral into a serious eating disorder. The four anorexics are tested to the limit, as they attempt to make and then eat their food nemesis, pizza! And Anna Richardson uncovers a disturbing new procedure in which a patient's own blood is literally sucked out and re-injected into their skin to make it look younger. Anna also heads back to ballet classes, where she tries, and fails to move like a prima ballerina.
