Jessica Simpson Reveals Secret To Her Post-Baby 100-Pound Weight Loss

Jessica Simpson, who welcomed her third child, daughter Birdie, six months ago, has revealed that she’s already dropped an amazing 100 pounds since giving birth. The 39-year-old fashion designer appeared on HSN with her mom to discuss her new clothing line and the hosts commented on her great figure.

"It's been a lot of hard work. I have to say that I have worked very hard," Simpson admitted. "Everything that I've been eating is mostly made with cauliflower. I don't like the word 'diet.' I just ate a bag of Cheetos in the back. I do think that writing down what we eat is important to keep ourselves in check."

On Instagram, Simpson shared a pic of her slimmed-down post-baby body, writing, “6 months. 100 pounds down (Yes, I tipped the scales at 240 😜) My first trip away from #BIRDIEMAE and emotional for many reasons, but so proud to feel like myself again. Even when it felt impossible, I chose to work harder. 💚”

The mother of three has been candid her pregnancy weight gain with her third child, saying that during pregnancy she tends to gain a lot of weight, but she also doesn’t have unrealistic expectations of getting back into clothes she wore before having children. She emphasizes, however, that it’s “all worth it.”

Before the launch of her new collection, Simpson says she had spent a few months in "workout clothes and sweats." She says she works out four days a week and counts how many steps she walks a day.

Simpson’s personal trainer Harley Pasternak told "E! News" that he worked with Simpson's doctor to develop a weight loss plan for her after she gave birth to Birdie Mae in March. Pasternak says they made small, sustainable changes to help her lose her pregnancy weight.

The trainer, who admits that he is not a fan of extreme diets or exercise, says the changes to Simpson’s routine included healthy alternatives to her favorite foods and walking 14,000 steps a day. Pasternak knows the designer well, having worked with her for the past twelve years. He says she started out slow after giving birth and slowing increased her daily steps by adding activities such as taking family walks and hitting the treadmill.

The biggest factor in Simpson’s successful weight loss, however, was her commitment to feel and look better. "We were kind of just getting in shape between kids and now it was sort of OK, I want to look fierce again and look great, confident and energized and I want to do it in a sustainable way," he said. "That was her main goal."

According to WebMD, a woman with average weight before pregnancy should gain 25 to 35 pounds while pregnant. Underweight women should gain 28 to 40 pounds, and overweight women may need to gain only 15 to 25 pounds during pregnancy. Also, women expecting twins should gain 35 to 45 pounds during pregnancy. However, if women gain more weight than they should during pregnancy, they should wait until after they give birth to lose weight.
