Jessica Simpson Weight Loss Method

After the birth of her third child, Jessica Simpson lost 100lbs in just six months! Her fantastic weight loss was aided by the help of her trainer Harley Pasternak, who has worked with Simpson after each of her pregnancies to help her lose weight.

This method is different from others we have seen, as Pasternak focused on creating healthy habits that would help Simpson not only lose weight but keep it off! Instead of creating a strict routine she had to follow, they incorporated five habits into her life that were easy to start and maintain.

Doing so helped her shed an impressive 100lbs in six months, and her self-confidence blossomed! In recent Instagram posts, Simpson has shared bikini selfies, saying not only how happy she is with her body but the progress she has made with, ‘self-love.’ 

The five habits Pasternak introduced include:

  1. Gradually increasing activity slowly to walking 14,000 steps a day.
  2. Eating three meals and two snacks from The Body Reset Diet.
  3. Spending an hour unplugged from technology a day.
  4. Getting at least seven hours of sleep every night.
  5. Completing three 45-minute sessions a week in the gym with her trainer.

These habits all helped Simpson to lose weight but changed her mindset and attitude too. By getting plenty of rest, gradually increasing her exercise, and eating a healthy and balanced diet, she has managed to lose 100lbs and looks fantastic for it!

This method might not sound as ‘conventional’ as hitting the gym every day, but it works! And it helped Jessica to create a positive mindset around healthy eating and exercise. Who doesn’t want that? This method sure seems to work and is one we are keen to hear more about!

Jessica Simpson Transformation

Jessica Simpson’s transformation is fantastic! She has managed to shed a whopping 100lbs from her body, and it shows! Her weight gained during pregnancy has disappeared, and she is boasting a flatter stomach and slimmer frame! 

We can also see her weight loss around her face, with her jaw becoming more defined. Not only does she look fantastic, but the smile on Simpson’s face says that she is much happier with her new slimmer frame!

She has still maintained some of her curves, but we can see she has a smaller chest and waist now. 

Let’s dig further into this to find out how Simpson achieved this fantastic transformation!

Jessica Simpson Workout Plan

A big part of Jessica Simpson’s workout plan includes the healthy habits we mentioned earlier. Two of these involved exercises: walking 14,000 steps a day and hitting the gym three times a week.

Walking 14,000 steps a day is more than the recommended 10,000 and was essential to keeping Simpson moving and active to help with weight loss! Her trainer eased her into this gradually, starting at 6,000 steps a day.

This exercise was not only gradual but was something Simpson could do with her children, motivating her to do it daily! Gradually, she increased to 14,000 steps a day, which is more than achievable with a long walk and pottering around the house.

The next part of her workout plan involved hitting the gym three times a week with her trainer! These sessions were for 45 minutes each that worked her entire body! Each of the three sessions has a different focus. There is a whole-body session, upper-body, and lower-body session to burn fat and tone Simpson’s body!

The workouts involve resistance training, some cardio, and conditioning at the end. While three workouts a week sound easy, these are designed to get you sweating and burning calories! Each workout burns around 300 calories, and you can check out some of these on Simpson’s social media!

Supplements Used

After taking diet pills for twenty years, Jessica Simpson no longer takes them or any supplements as part of her weight loss method. Instead, she has focused on incorporating healthy habits and a structured routine that has allowed her to lose weight and focus on living a healthier and happier life!

Jessica Simpson Meal Plan

Another one of Simpson’s healthy habits was to eat three meals and two snacks a day from ‘The Body Reset Diet’. This is her trainer’s book, and it is packed full of tasty meals and treats that can help you improve your health and lose weight!

Simpson’s meals included healthier versions of Tex-Mex or Tortilla soup that provided her body with the nutrients it needed to get through her tough workouts! The meal plan in Patersnak’s book is incredibly varied too, with each meal including fat, fiber, and protein.

Her two snacks were a combination of fiber and fat too, fuelling her through the day and satisfying any cravings she might have!

The meal plan also allowed for ‘indulgences,’ such as birthday dinners or date nights, where Simpson would want the free reign of what she ate! As she and her trainer were focusing on creating healthy habits, the goal was to build a good relationship with food rather than being overly restrictive!

How Much Weight Has Jessica Simpson Lost (And Current Weight)?

Jessica Simpson has lost a whopping 100 lbs in the space of six months following the birth of her third child! This weight loss took her down from her heaviest weight of 240lbs to 140lbs, or 63.5kg, a far healthier weight for her height.

Her current weight, however, is unknown. As part of her workout routine, Simpson focused on healthy habits and a holistic approach, which does not involve stepping on the scales. She revealed on TODAY that she has ‘no idea’ how much she weighs, moving away from the notion that numbers define her.

However, as she seems to have maintained her weight loss, we can assume she still weighs around the 140lb mark!

How Has Jessica Simpson Maintained Her Weight?

Jessica Simpson has continued to walk daily and incorporate workouts into her week. She now eats a balanced and varied diet that allows her to maintain her weight. However, she is very open about the fact she is not regularly weighing herself.
