2. No Scales

Harley Pasternak, Jessica’s trainer, told People that his star client avoids weighing herself. “I never work with scales. My work with her is more about the habits she’s created and kept up. And as a byproduct of doing these habits, she lost 100 pounds,” he said. She added to Today: "I have no idea how much I weigh," she said. "I just want to feel good and be able to zip my pants up. If I don't, I have another size. I have every size."

3. Exercise

Jessica works out with Harley Pasternak regularly. At one point she was doing 45-minute strength and weight training sessions three days a week. She also gets a lot of steps in, starting her fitness journey with a goal of 6,000 steps per day, eventually building up to 14,000, per E! News. “It’s a social thing that she can do with her kids," Pasternak said about walking.

4. Pushing Herself

Jessica is all about pushing herself. “First day back at it and I’m already hurtin’ and feelin’ real dramatic about being sore. I have been craving this, but procrastinating. One work out and I am determined to not let myself down. Although I will be eating a brownie to give myself some points!” she captioned an Instagram post of herself on the treadmill.

5. Yoga

Jessica regularly does yoga, a great workout according to Harvard Health. “Researchers found that people who practiced yoga for at least 30 minutes once a week for at least four years, gained less weight during middle adulthood,” they said. “People who were overweight actually lost weight. Overall, those who practiced yoga had lower body mass indexes (BMIs) compared with those who did not practice yoga. Researchers attributed this to mindfulness. Mindful eating can lead to a more positive relationship with food and eating.”

Singer, actress, and fashion maven Jessica Simpson has been open about her struggles with her weight. ​​In a 2010 interview with Oprah, Simpson talked about her struggles and how she came to love her body. ”Every day, we'll find something new out about ourselves that is authentic and is unique, but I really just finally relaxed. I don't care what people have to say about my weight. I really don't, because I think I look great," she said at the time.

2. She Works With A Personal Trainer

After having her third child in 2019, Simpson worked with celebrity trainer, Harley Pasternak, to shed the baby weight. Simpson revealed on Instagram that while working with Pasternak, she dropped 100 pounds, and weighed 240 pounds while she was pregnant. “6 months. 100 pounds down (Yes, I tipped the scales at 240),” Simpson captioned the photo showing off her weight loss. Pasternak toldE! News that he worked with Simpson to make sustainable changes to her lifestyle. “It had to be more than just getting back from her baby weight, but how do I keep whatever I am doing now forever,” he said. “That’s why we are not a big fan of doing any extreme diet or radical forms of exercise.” Pasternak praised Simpson’s drive and commitment in the same interview. “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.”

3. She Worked With A Dietician

Simpson also works with nutritionist Liz Josefsburg, on her diet and meal plans. Josefsburg told HollywoodLife.com about her and Simpson’s process on developing her diet. “She spent well over 6 months working off weight from her first and second pregnancies. She ate regular meals throughout the day. Usually three times and a snack. The key for Jessica was moderation and learning to indulge intelligently.”

4. She Gets At Least 10,000 Steps In A Day

Simpson makes sure to get her steps in everyday. Simpson’s trainer, Harley Pasternak, told E! News that one of the changes he and Simpson made involved increasing her daily steps to 14,000 a day. Simpson’s nutritionist, Liz Josefsburg, agreed. "Jessica loves to walk. She gets out almost every day to hit at least 10,000 steps. She loves it because she can do it anywhere, she can do it with her family and it helped her lose weight after every baby," she said to HollywoodLife.com.

5. She Stays Hydrated

Simpson tries to stay hydrated throughout the day, as recommended by her nutritionist, Liz Josefsburg. Josefsburg told HollywoodLife.com, “Hydration is a secret weapon for weight loss. In my book Target 100 I urge people to get in at least 100 ounces per day. Which might seem like a lot, but it is right for our bodies. Staying fully hydrated while losing weight is critical. Much of the overeating we do is mistaking thirst for hunger. If we can keep our bodies, which are made up of over 60% water, hydrated, they burn calories and metabolize food at an optimal rate!”

Jessica Simpson, the singer, actress, and fashion designer, has yo-yo dieted over the years.

1. She Worked With Two Trainers to Feel Like Herself Again

She worked with not one, but two trainers to shed 100lbs. Harley Pasternak and Sydney Liebes helped Simpson with her full body workouts multiple times a week for 45 minutes. After slimming down, Jessica decided not to focus on the scale. She dropped 100lbs in just 6 months, then stopped putting emphasis on the number. “I couldn’t handle being so big and my ankles were swollen. So I’m just happy to feel comfortable again. I was literally uncomfortable for so long that now it’s just nice to relax,” she said.

2. She Followed Her Doctors' Advice

She’s always worked with her doctor on what weight loss plan she should try. She enjoyed Weight Watchers, even acting as a spokesperson for them at one point. During her pregnancy, her and her doctor decided she would not be following the Weight Watchers plan while pregnant. They work closely on what’s best for Jessica’s health.

3. The Challenges Grew, But She Faced Them Head On

Jessica has fluctuated with her weight on and off for years. After each baby, it became that much more difficult. Pasternak helped her each time. “My mantra is you get lean in life, and strong in the gym. So the majority of the weight loss actually came from everything she did outside of the gym, and then everything in the gym is about toning and tightening,” Pasternak says.

4. She Cheats Here and There

Jessica is allowed to cheat here and there. “If she has a birthday party one night and a date night another night, she’s going to indulge both of those nights, but that’s it. It’s about balancing in a way that doesn’t make it painful or too much of a departure from your life before that,” said Pasternak. Jessica admits it’s been a lot of hard work.

5. She Enjoys Walking

One of the first things Simpson did to get to a healthy place after Birdie was born is start walking. It’s low impact and gets the body moving. She’d slowly increase her daily step count, aiming for 12,000-14,000. “If I haven’t moved enough, I’ll make sure and get in extra steps the next day,” she said.
