On Thursday, Jessica Simpson was brought to tears while celebrating her body in a new bikini photo on Instagram.

The 41-year-old debuted her 100-pound weight loss in September 2019. Since then, her trainer Harley Pasternak has revealed the details, along with the five key habits Simpson added to her daily routine.

In her latest post, Simpson said, "I have gained and lost 100lbs 3x, so I never thought this moment could or would happen, but I’m finally spring breakin’ wearin’ a BIKINI! Hard work, Determination, Self Love. I enjoyed a good proud cry today. 💪🏼☀️💛"

In a 2019 interview with People, Pasternak revealed that he never works with scales and prefers to focus on keeping Simpson on track with her healthy habits. The two planned a more holistic approach after the birth of her third child Birdie Mae. Simpson confirmed on TODAY that she has "no idea" how much she weighs.

"The difference between this and the other times was that she worked out, yes, but her transformation was more about what she did on her own time,” Pasternak told People. “I’ve kind of helped her come back after each baby, and this is a bit different, in that she said she was tipping the scales at 240 [post-delivery]. This is sort of the aggregate of being pregnant nonstop for a decade, and so we had a little more of a challenge between this and the other ones."

Here are the five healthy habits Simpson practiced.

1. She walked 14,000 steps daily.

Pasternak eased Simpson into activity slowly, starting with walking 6,000 steps daily. “It’s a social thing that she can do with her kids," he says. Slowly, she built up to 14,000 steps, according to E News.

2. She ate three meals and two snacks from The Body Reset Diet.

Eating healthfully played a big role in her weight loss. Simpson followed Pasternak's Body Reset Diet, which allows for three meals and two snacks each day. Each meal includes protein, fiber, and fat while snacks are a combo of protein and fiber or protein and fat.

“She’ll have foods that are very flavorable that are healthier versions of things like a tortilla soup or Tex-Mex," he says. The healthy eating plan also allows for indulgences. "And 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," Pasternak told the publication. "It’s about balancing in a way that doesn’t make it painful or too much of a departure from your life before that.”

3. She hit the gym with Pasternak and trainer Sydney Liebes.

She completed 45-minute sessions three days a week, and impressed her trainers along the way. "You have worked your ass off and the reward is priceless!" Liebes shared in a congratulatory Instagram post. "I’ve been training for 10 years now and I have never been more excited for a client transformation."

4. She spent 1 hour unplugged from technology every day.

Simpson's weight loss was about much more than working out and eating right. "Unplugging from technology" for at least an hour every day helped her get restful sleep, Pasternak told E News.

5. She logged at least 7 hours of sleep every night.

Good, quality sleep was key to Simpson's success. "So many people undervalue the importance of sleep in weightless and weight management," Pasternak told E News.

Once she completed her other tasks, she could really rest. "Every night before she goes to bed she sends an email showing that she hit all five tasks, so she’ll go to bed feeling successful," Pasternak told People. "She’s hit her step goal, she’s eaten well, she’s balanced her responsibilities — so she can go to bed with a sense of fulfillment, and that’s everything."

Her attitude made a difference, too. “She was so motivated and positive. She was saying that her body has not belonged to her for the past decade. Not in a bad way, in a positive way—her body has been designated to create life and now it’s hers again and she’s going to make it fantastic in a really enjoyable way.”
