Their wedding day is the most exciting and stressful occasion of most women’s lives, and there’s one BIG worry that plays on every bride’s mind: her weight!

You Are What You Eat’s formidable diet dictator, Gillian McKeith, turns her attention to the run-up to the big day in three hour-long specials which will air on Channel 4 this June.

Gillian takes on three bulging brides-to-be per episode, who compete to lose weight by sticking rigidly to her regime, with the eventual winner being rewarded with a dream designer wedding dress.

Along the way, the brides receive Gillian’s unique brand of help to make their wedding day as special as possible. She hears from their fiance, friends, family and prospective in-laws as she gets to the bottom of their weight issues and worries about the big day.

Three Fat Brides, One Thin Dress (working title) follows the brides during the eight-week race into the lace as, along with the usual pre-wedding jitters, they contend with teetotal hen nights and a his n hers pre-wedding colonic.

Will the brides cope with the added pressure of Ms McKeith on the scene? Will they make it to their big day a few sizes smaller? Or will they want to call the whole thing off?
