Wonder Years star Danica McKellar looks slim months after baby's birth, says it's down to her love of maths

 

It's been just seven months since Danica McKellar gave birth to her first child, gorgeous son Draco, but already she's back to her slender best.

And the former actress revealed her secret at the LA Book Festival, though it's a cure that some will find less appealing than childbirth itself.

Danica, 35 , says her physique is all down to her preoccupation with mathematics, yes that's right, doing sums keeps her slim.

'I don't really have time to eat as I'm too busy working on my math or with Draco,' she told fanzine Number Zen at the star-studded event yesterday.

'It's such a diversion to be constantly thinking of better ways I can teach people math that my hunger is for that really, for new ways of translating the beauty of it.'

We're not buying that most people would happily swap a Flake for a fraction, or embrace a binary subtraction as readily as a bacon sandwich.

But then Danica, who played Winnie Cooper in the hit American comedy drama, is an education advocate for mathematics.

She's also the author of three best-selling books for junior high schoolgirls, entitled Math Doesn't Suck, Kiss My Math and HOT X: Algebra Exposed, so it's far to say she has a passion for the subject.

The brunette beauty gave a speech at the event but was mortified when her papers blew away in the Santa Ana winds: 'It added a bit of drama,' she said.
