Kristin Cavallari's Bikini Weight Loss Secret Is Paleo-Style Diet, No Cardio Exercise

Kristin Cavallari is a mom-of-three who has an enviable bikini body, thanks to a weight-loss regimen that includes a Paleo-inspired diet and weightlifting workouts. Surprisingly, the reed-thin Cavallari does no cardio exercise.

The Hills alum is a budding fashion designer who now stars on her own TV show, Very Cavallari, which premieres July 8.

Unlike many reality TV stars whose show-business "careers" fizzle as soon as their shows end, Kristin has successfully branched out as a fashion designer and lifestyle guru who recently wrote a healthy cookbook.

Cavallari is a longtime workout fanatic who made headlines when she lost all her baby weight after each of her three pregnancies in record time. After two of her pregnancies, Kristin lost 20 pounds in two months.

Kristin said the secret to her rapid weight loss was a gluten-free, Paleo-inspired diet that limits processed foods, and emphasizes high-quality proteins and healthy fats such as coconut oil, butter, and grass-fed beef.

"I don't do any cardio," she told Delish. "Cardio used to be all I did before I had kids, but once I had them my lifestyle changed. I'm a much healthier eater, and I hardly drink alcohol, so I've found that it's about building and maintaining muscle rather than losing weight now."

Another celebrity mom who's fitter after having children is Kourtney Kardashian, who has a sizzling bikini body at age 39, thanks to a low-carb ketogenic diet and daily workouts, as the Inquisitr has reported.
