UPDATE: Danica tells the Huffington Post that the Daily Mail's report about her post-baby weight loss method is completely fabricated. She has slimmed down simply by eating lots of healthy food, she said in an email statement:
While I’m flattered at the praise for losing my baby weight, I’m horrified at the irresponsible, unhealthy method by which they claimed I did it! This false story would have people believe that I simply don’t have time to eat, due to being too distracted by writing my next math book and taking care of my baby. Nothing could be farther from the truth. I eat constantly because I’m still breastfeeding around the clock. My “secret” is what I eat – it’s all healthy food: Whole grains, lots of fresh vegetables, organically raised chicken and meat, and almost no refined sugar, dairy, or gluten. I exercise at home – light cardio and yoga.. But make no mistake about it. The volume of healthy food I eat is, well, huge!
Last month Danica blogged about how she lost almost all the 40 pounds she gained during pregnancy through discipline and yoga.
"After that first month, when I was finally walking like a person again and not a Neanderthal, I began with yoga – gentle, restorative yoga that helped my body finish healing," she wrote.
PREVIOUSLY: 'The Wonder Years' alum Danica McKellar gave birth to son Draco in September, and over the weekend at the Los Angeles Times Festival of Books she talked about how she lost the baby weight so quickly: math.
"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 (via the Daily Mail.)
Danica, 36, studied math during college at UCLA and is an education advocate who has written three New York Times bestsellers encouraging girls to succeed at math.
"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," she told Number Zen.
Danica looks as great as she did when she stripped for Maxim pre-pregnancy last year.
