Danica McKellar is in the best shape of her life at 40, thanks to a low carb gluten-free Paleo-style diet, yoga workouts and lots of dancing, Celebrity Health reported.
"I don't eat gluten, I don't eat dairy, I don't eat sugar," said McKellar. "And the only thing I drink is water. I eat really, really clean. I'm very strict."
Danica, who starred on the hit TV series "The Wonder Years" from 1988 to 1993, said she doesn't deprive herself, but makes a point to fill up on nutrient-dense, whole foods.
The Paleo diet is an alcohol-free diet that emphasizes high-quality animal proteins, healthy fats, non-starchy vegetables, and excludes gluten, sugar, dairy, legumes, and processed foods.
Research suggests the Paleo diet accelerates weight loss, reduces blood pressure, and prevents cancer, diabetes, heart disease, depression, and even Alzheimer's. A recent study published in the European Journal of Clinical Nutrition indicates the Paleo diet is twice as effective as other diets for promoting weight loss and reducing belly fat.
“Clinical trials have shown the Paleo diet is the optimum diet that can lower the risk of cardiovascular disease, blood pressure, markers of inflammation, help with weight loss, reduce acne, promote optimum health and athletic performance,” said professor Loren Cordain, author of The Paleo Diet for Athletes and The Paleo Diet Cookbook.
The super-toned McKellar, who competed on season 18 of "Dancing With the Stars," said her usual workouts are low-impact and center around yoga. "I do yoga, I actually have a yoga DVD called 'Daily Dose of Dharma, " said Danica.
Danica worked out up to seven hours a day for "Dancing With the Stars" with partner Valentin Chmerkovskiy. She said the grueling dance training is fun but exhausting.
After McKellar hit it big as a child star, she pursued a mathematics degree at UCLA and graduated with honors. Danica then went on to write three New York Times-bestselling math books for children, including Girls Get Curves: Geometry Takes Shape.
