Sassy Samantha had potential to be a star, but her ambitions for glitz and glamour have been gobbled up by her love of wine and chunks of cheese. In recent years she's ballooned from a petite size 12 to a generous 18.

Competing with Sam for the dress of her dreams is 28-year-old Ngozi from North London, a binge eater who packs away loaves of bread and packets of cookies. Rather then looking forward to her big day, Ngozi is dreading it.

Finally, Deborah is approaching her big four O as well as her big day and is five stone overweight. She is a comfort eater whose sugar cravings really take the biscuit.

Deborah has opted for a sunshine wedding in Florida, but with her wedding dress fit to burst at the seams, she knows she'll look more Miami vice than virtue if she doesn't lose weight.
