Simpson has maintained her 70-pound post-baby weight loss and toned legs for two years, courtesy of yoga, walking and a low-carb diet.

The busty 5-foot-3 Simpson lost 70 pounds after giving birth to son Ace Knute in June 2013. Simpson lost the same amount of weight six months after giving birth to daughter Maxwell in May 2012.

Simpson, a rep for Weight Watchers, has credited a low-carb diet and rigorous daily workouts for her dramatic weight loss, Examiner reported.

Jessica Simpson said gaining 70 pounds during her pregnancies was depressing and made her insecure.

Jessica’s low-carb diet typically features a mix of high-quality proteins like salmon and chicken and fresh vegetables and salads. Simpson also avoids processed foods and limits sugar.

Low-carb diets like the Atkins, Paleo and ketogenic plans promote rapid weight loss by forcing the body to burn body fat for fuel, said obesity expert Dr. Eric Westman, co-author of Keto Clarity.

Recently, a Canadian mother-daughter duo credited a low-carb, high-fat ketogenic Paleo diet for their combined 110-pound weight loss.

Laura Childs and her daughter Veronica lost 65 pounds and 55 pounds, respectively, several months after embarking on a low-carb, high-fat diet. They have maintained their weight loss for more than a year.

Laura and Veronica chronicled their stunning weight loss in their book, Low Carb High Fat No Hunger Diet: Lose Weight With A Ketogenic Hybrid. The Childs’ book details their prior weight struggles, the science behind ketosis and 75 delicious, easy low-carb recipes.

For exercise, Jessica Simpson walks a minimum of four to five miles every day (or 8,000 to 10,000 steps) and does yoga. Simpson also works out at the gym for 45 minutes, four days a week, with her longtime trainer Harley Pasternak, creator of the 5-Factor Workout DVD.

Simpson’s longtime trainer, Harley Pasternak, said the foundation of Jessica’s workout routine is daily walking. Pasternak, author of 5 Pounds, also trains Halle Berry, Lady Gaga, and Kim Kardashian.

Pasternak and Jessica Simpson typically work out at the gym four days a week, combining 10 to 20 minutes of cardio exercise, 20 to 30 minutes of resistance training, and lots of flexibility moves.
