Duchess Of Pork Discoursing On Light Courses

Once upon a time, she was called the Duchess of Pork.

Now, she’s shed those extra pounds - not to mention the dead weight of a royal husband - and lived to dish about her life in, of all things, a Weight Watchers cookbook.

Or so we had hoped. But “Dining With the Duchess: Making Everyday Meals a Special Occasion” (Simon & Schuster) doesn’t serve up much in the way of juicy details.

On the subject of the royal family, the former Sarah Ferguson (now a Weight Watchers spokesmodel) remains respectfully mum.

The fare featured in the book is l-i-t-e, as in baked chicken with wine, which boasts 147 calories and 3 fat grams per serving. Other dishes, like crunchy fennel salad and a beet-and-apple “Napoleon,” are no doubt designed to help you lose weight by driving away your appetite.

But the slim volume takes on weight whenever the duchess divulges information about her own battle of the bulge.

You’ve gotta sympathize with a gal who freely admits to having binged on baked beans and savored scores of sausage rolls and mayonnaise.

“I did the mad crash diets,” she writes, “like the one when I lived on meat and oranges so that I could lose 26 pounds to fit into my wedding gown!”
