Simpson works with celebrity trainer, Harley Pasternaak, to help her stay in shape, and help her eat right. Pasternaak tells People that after Simpson gave birth to her third child, he put her on his “Body Reset Diet”, to help her lose weight. “It’s three meals and two snacks a day, and each meal has protein, fiber and fat, and snacks are protein and fiber or protein and fat,” he says. “She’ll have foods that are very flavorful that are healthier versions of things like a tortilla soup or Tex-Mex. 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. 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 Sets Goals

Pasternaak tells People that he doesn’t have Simpson use a scale in his work with her. He says that he has her set different goals for herself, which include a list of daily tasks. “My work with her is more about the habits she’s created and kept up. 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. 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. And as a byproduct of doing these habits, she lost 100 lbs.”

4. She Doesn’t Weigh Herself

Simpson said on the Today Show that she doesn’t like to weigh herself. Instead, she focuses on how she feels, and how her clothes fit. "I have no idea how much I weigh," she said. "Like, 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."

5. She Got Sober

Simpson is open about being sober, and celebrated four years of sobriety this past year. In a revealing Instagram post, Simpson reflected on her sobriety. She wrote, “This person in the early morning of Nov 1, 2017 is an unrecognizable version of myself. I had so much self discovery to unlock and explore. I knew in this very moment I would allow myself to take back my light, show victory over my internal battle of self respect, and brave this world with piercing clarity. Personally, to do this I needed to stop drinking alcohol because it kept my mind and heart circling in the same direction and quite honestly I was exhausted. I wanted to feel the pain so I could carry it like a badge of honor. I wanted to live as a leader does and break cycles to advance forward- never looking back with regret and remorse over any choice I have made and would make for the rest of my time here within this beautiful world.”

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!”
