Katie has always had some problem with her weight, though it wasn't until she started Slimming Zone did she connect with people just like her. Katie hasn't had much luck in the romance department, though she has her eye on someone at work, Alex. Alex is a gorgeous man, who is tall and Katie can't help but fancy him. So, when he keeps asking her on dates but it doesn't really mean a date, she doesn't know what to think. When things start to move forward in a positive direction, it doesn't take long for things to start falling apart, her love-life, her job and her weight.
Jane is a mother of two who couldn't shift the baby weight after having her children, though with her youngest being over five years old, and she still can't get back to her pre-baby figure. Jane works in the television business and she has quite a stressful job, looking after two children and her husband, Andy but is determined to lose the pounds she turns to diet pills which make her nothing if not ill. Though, even after knowing diet pills are bad for her, she make a choice that puts her future in jeopardy.
Ellie works with Katie, they both came to Slimming Zone together, to help and encourage each other to lose weight. Just like Katie, Ellie hasn't had much luck in love either, but it seems that her luck is turning around. Thomas, someone who seems to like her just as much as she like him, but they are in that beginning stage of their relationship, especially having kissed once and promptly avoided each other for weeks afterwards. Ellie seems to be the one that Katie talks to the most, and they both were quite close before they meet Jane and Pixie in Slimming Zone.
Pixie was the second one of the four to join Slimming Zone, Jane had join a year before hand, she just like Jane had children and a husband at home. Well if you can call him that anyway, he doesn't help with their children and would more likely to be seen in the pub than helping anyway shape or form. Pixie hasn't been happy in a long time, they both slept in separate bedroom and Pixie had several escape plans over the years but having not worked in a lot time, she has no other choice but to keep trying at their marriage whether it worked or not.
