After Jessica lost a lot of weight after welcoming her third child, everyone wanted to know why. Her trainer, Harley Pasternak, told People that one of her tactics was actually not focusing on numbers. “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,” the trainer-to-the-stars dished. She recently revealed on Today that she doesn’t weigh herself. "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."

2. She Uses Activity Trackers

Jessica counts her steps. When she first started on her exercise journey, her goal was 6,000 steps per day. Eventually she built it up to 14,000, per E! News. “It’s a social thing that she can do with her kids," Pasternak said.

3. She Is All About Healthy Eating

Jessica follows Pasternak’s Body Reset Diet, eating three healthy meals a day of protein, fiber, and fat-rich foods and two snacks 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 explained. The healthy eating plan also allows for indulgences. However, she is allowed to splurge on occasion. “It’s about balancing in a way that doesn’t make it painful or too much of a departure from your life before that.”

4. Her Workouts Are Hardcore

Jessica makes sure to give her body time to recover. "So many people undervalue the importance of sleep in weight loss and weight management," Pasternak told People.
