Jessica Simpson has been honest about everything from her career ups and downs to her sobriety journey and her relationship with something very close to home. In fact, it is her home: her body.
In April 2022, the singer, actor, entrepreneur and mom of three took to Instagram to share a radiant, smile-filled photo to celebrate a major milestone. “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!!!!!!”
How Much Weight Can You Safely Lose in a Month?
She’s not alone in terms of the weight-loss roller coaster, saysMary Stewart, RD, LD, a registered dietitian and the founder of Cultivate Nutrition in Dallas. That ride’s name: weight cycling. “Weight cycling is defined as repeated attempts at losing and gaining weight. Some studies show the role weight cycling may play in adverse health events,” says Stewart.
The adverse effects of weight cycling include a higher risk of depression, per a 2024 study inBMC Public Health. Frequent weight cycling may also lead to obsession with the scale, increase shame and weight stigma and further encourage extreme behavior to lose weight, per a 2024 study inQualitative Health Research. And a 2022 study in theJournal of Cardiovascular Nursingsuggests that weight cycling predicted poor sleep in women.
So, why might someone lose and then regain the weight (and more)? “One of the biggest reasons yo-yo dieting is a struggle for so many is because the dietary approach is not sustainable for that individual’s lifestyle,” says Stewart. “Unfortunately, many trendy diets create unnecessary drastic and strict dietary changes, which are not feasible to maintain, and therefore these diets are not designed in a way that leads to true habit change.”
How Did Jessica Simpson Lose Weight?
So what is this “reset,” exactly, and how did it help the fit mom change her life once and for all? We asked Stewart and Michelle Hyman, RD, a registered dietitian specializing in weight management in Long Beach, New York, for the scoop.

Not everyone will find this diet doable, particularly in how Phase 1 is extremely smoothie-heavy. “Consuming meals in liquid form is not necessary for weight loss. For many people, this may not be enjoyable or palatable,” explains Hyman. “Smoothies, even when they contain fruits and vegetables, may not be as filling as solid meals. During the first two phases, the focus on smoothies can be difficult for individuals who enjoy eating shared meals with their loved ones at home or at restaurants.”
As for Stewart, she’s a huge fan of smoothies. “They are a great way to pack in the nutrients in a convenient way. With that said, only drinking a smoothie for each meal, as referenced in the first phase of the diet, can be too challenging and encourage a caloric restriction that is too severe and unnecessary,” says Stewart.
In later phases, if you choose yourvegetarian mealsand snacks wisely, you can fuel up in a well-balanced way, Hyman and Stewart agree, but that’s a lot easier said than done. It can take a lot of planning to ensure each of your smoothies, meals and snacks offers enough protein, fat and carbs to provide enough energy.
The overall tenets are fairly sound, however, Stewart says, especially if you allow for more flexibility in the plan. “The combination of daily movement, consistent mealtimes, focusing on whole foods including a balance of fiber, healthy fats and lean protein, and prioritizing sleep will give the body the foundation it needs to maximize health,” says Stewart.
Just know that there’s nothing magic about Simpson’s specifics of meals and snacks, step counts and unplugged time. It’s what works for you that matters. “According to research, there is actually no one optimal eating frequency for weight loss. Three meals and two snacks a day may work great for some, but not others,” says Hyman.

One smart move you can take from Simpson is ditching the scale. “I appreciate how she tries hard to not let a number on the scale define her. The number on the scale is just one way to measure health and certainly does not tell the whole story,” notes Stewart.
The Bottom Line
Should you try Jessica Simpson’s diet? While there are benefits to the diet, including the focus on whole foods and consistent mealtimes, you do not need to follow the diet in order to lose weight or improve your health. In fact, you can lose weight and feel good with small changes, rather than entire lifestyle overhauls.
“When making any dietary or lifestyle change, it’s about progress, not perfection, and making small, sustainable improvements. Once that particular change becomes a habit, you can build on it,” says Stewart. For instance, you might replace a vending machine snack with a smoothie this week, focus on sleep the next week and tack on 30 minutes of unplugged time the following.
For the best chance at finding a diet plan that’s right for you and your lifestyle and gives you the optimal strategy for successful weight loss that you can maintain long-term, Hyman suggests consulting with a registered dietitian for individualized weight-loss advice.
