jessica simpson weight loss

Last Updated:

Jessica Simpson gained a substantial amount of weight when she was pregnant with her third child, Birdie Mae. According to Simpson, she tipped the scales at 240 pounds during her pregnancy.

However, in the six months since her child’s birth, she has managed to shed all of the weight that she lost. In just half a year, Simpson managed to lose an incredible 100 pounds [1].

What’s truly impressive about Simpson’s weight loss is that she managed to slim down in a healthy way. Her personal trainer, Harley Pasternak, worked with Simpson’s doctor to develop a plan that would help her to lose the weight and keep it off.

Instead of starving herself or following a crash diet, Simpson made small changes that had a big impact.

While the average person may not be able to afford a personal trainer, anyone can implement the weight loss strategies that Simpson used. Even though these tricks seem simple, it’s hard to argue with Simpson’s amazing results.

1. Finding Substitutions

It can be hard to give up your favorite foods, especially when you’re following a restrictive diet. When you’re hungry, it’s hard not to be tempted by pizza or a big bowl of pasta.

That’s why Simpson’s trainer worked to find healthier alternatives to some of the high-calorie foods that Jessica loves [2].

These kinds of substitutions are easy to make, and they won’t necessarily have a big impact on the flavor of your food. For example, if you’re craving pasta, you can choose a whole wheat pasta rather than a pasta that’s made from white flour. Instead of topping a dish with sour cream, you can use fat-free yogurt.

Lean turkey is a great alternative to ground beef, and using applesauce instead of oil allows you to cut calories when you’re cooking.

Because Jessica has a sweet tooth, one of her go-to meals was a sweet and healthy apple pie smoothie. Denying yourself the foods you want is bound to end in failure. Jessica was able to successfully lose weight because she made sure her meals included the kinds of flavors that she loves.

The foods you love may not be diet-friendly, but that doesn’t mean you have to give them up for good. Instead, you should look for substitutions for the foods you want to eat. That way, you’ll be able to indulge your cravings without breaking your diet.

2. Walking Your Way To Weight Loss

Not everyone that wants to lose weight has the time or the energy to put in a grueling workout at the gym. Instead of opting for intense workouts, Simpson chose walking as her primary form of exercise. Under the guidance of her trainer, Simpson worked her way up to walking 14,000 steps each day.

Focusing on walking also allowed Simpson to include her family in her workout. While Jessica has said that she did spend a lot of time on the treadmill, she also started a tradition of family walks. She started out slow while she was recovering from childbirth, but every day, she focused on walking more than more.

If you want to lose weight by walking, you’ll want to use some sort of fitness tracker that will help you to monitor your steps. You shouldn’t try to walk 14,000 steps a day immediately.

Instead, you may want to try to walk more and more each day. If you walk on a daily basis, your endurance levels will start to increase. Before you know it, walking thousands of steps every day will feel more than manageable.

3. The Body Reset Diet

The diet that Simpson’s doctor and nutritionist developed was based on the Body Reset Diet. This diet encourages participants to eat protein, fiber, and healthy fats in all of their meals. The diet is designed to power your metabolism so that you are able to lose weight quickly.

Eating protein and fiber is important because it will leave you feeling full for longer, which means it will be easier for you to eat appropriately sized portions. When you eat healthy fats, your body will burn the fat stores that it has.

These principles are easy to apply, and they may be able to give you some results.

It’s important to remember that you don’t have to follow any diet plan to the letter. While the initial phase of the Body Reset Diet requires you to eat three smoothies and two crunchy snacks a day, Simpson followed an adapted version of the diet. You can look at this diet and other diets for inspiration, but your ultimate goal should be to find a healthy diet that you can stick to.

4. Eat Regularly

A lot of people make the mistake of starving themselves when they’re trying to lose weight. If you’re not taking in any nutrients, your body will want to hold onto fat stores. You’ll have much better results if you make a point of eating throughout the day.

Although Jessica Simpson did monitor her calorie intake, she also made sure she was getting all of the food that she needed. While on the diet, she ate three meals and two snacks every single day. Eating throughout the day can keep you from feeling hungry, and it can also speed up your metabolism.

Snacks aren’t usually associated with weight loss, but the right kinds of snacks can actually help you to slim down. Nuts are high in healthy fats, and research has shown that they can help people to lose weight [3]. Hardboiled eggs also make a fantastic snack. Some studies show that eating eggs can reduce the total number of calories that you consume [4].


You might be able to lose weight on a crash diet, but you’ll struggle to keep that weight off. If you want to slim down, you should follow Jessica’s example and make sure you’re eating the meals you need every day.

Jessica Simpson’s weight loss is inspiring. Whether you’re hoping to get back to your pre-pregnancy weight or you are simply looking for ways to slim down, you should try out some of her weight loss tips. This is a healthy and highly effective way to get down to your goal weight.
