Danica McKellar Reveals Secrets to Her Hot Body Photo Credit: PacificCoastNews.com She may say she's not ready to jump back into the dating scene quite yet, but Danica McKellar, 38, looks absolutely amazing, as seen in pictures from a recent Avril Lavigne music video shoot. The former "Wonder Years" star spills the beans or maybe the kale on how she stays in such a good shape, especially with a son who's turning 3 in September. "It is like 80 percent diet," she told ABC News today during a visit to promote her new book "Girls Get Curves: Geometry Takes Shape." I eat really, really clean. I eat kale. I eat quinoa. I eat organic chicken. I drink water. I don't drink coffee and I hardly drink alcohol. I don't drink soda ever, not even diet soda.
