Sarah Ferguson The Duchess Of York Reveals She's Lost Three Stone

Sarah Ferguson has revealed her dramatic three stone weight loss in a photoshoot with Hello! magazine.

The 54-year-old Duchess of York said she was spurred into fitness action when she reached the same weight she was when pregnant with Princess Beatrice.

She told the mag her weight gain "really frightened" her. "Beatrice was an 8lb baby and I was only 6lb off my full-blown pregnancy weight. I decided to make a change.

"I used to be so angry. I believed I was never going to lose the weight. I was just drowning in food," she went on.

"It took courage to go out in public in all the years I have been overweight.

"Every time there was a 'Duchess of Pork' or 'Fat Fergie' headline, they didn't have any idea they were reaching to the depths of my soul."

Fergie took action and flew out to Swiss ski resort Verbier for a gruelling boot camp training regime which saw her lose three stone in five months.
