BOTTOM LINE: Naturally Slim is a diet program based on the principles of mindful eating. It helps you build new mealtime habits and lose or maintain weight without counting calories or tracking your food intake.
Naturally Slim is a diet program that utilizes the principles of mindful eating. It helps you replace unhealthy eating habits with healthier ones, which may aid weight loss and weight maintenance.
Mindful eating is a strategy that focuses on recognizing your hunger cues, savoring your food, solely focusing on eating during mealtimes, eating slowly, and paying attention to when your body starts signaling that it’s full (
The program requires no special foods, supplements, or supplies, and no calorie or intake tracking. Additionally, it doesn’t restrict or limit any foods. Instead, it teaches you how to make healthier choices as you progress through the lessons.
How it works
The paid, year-long program is divided into three phases:
- Foundations: 10 weeks of basic lessons about nutrition, fitness, and mindful eating principles
- NS4You: 10 weeks of biweekly lessons that are customized to your needs
- NS4Life: 32 weeks of once-monthly lessons that help you better understand how to stick to a healthy lifestyle for life
While many of these lessons are about mindful eating practices, several also address other facets of a healthy lifestyle, such as nutrition, hydration, exercise, sleep, and stress management.
The program is fully online, so you’ll need internet access via either a computer, tablet, or smartphone.
In addition to access to the lessons, you’ll receive access to NSTown, an exclusive online community that’s only available to paying members of the Naturally Slim program.
Additionally, you can email Naturally Slim counselors at any time during your program.
Some of the basic mindful eating principles that you may learn to put into practice throughout the Naturally Slim program include:
- sitting down to your meal with no distractions
- putting your fork or spoon down between each bite
- chewing each bite of food thoroughly before swallowing
- eating for at least 10–15 minutes at each meal, rather than rushing through it
- stopping eating when you feel full
You can pay for the Naturally Slim program either monthly or annually. Pricing details are as follows:
- Monthly: $50 per month
- Annually: $450 per year ($37.50 per month)
This is the full price, but there may be special sales or promotions that can help you save money.
Additionally, Naturally Slim has partnered with several large employers to offer their program for free or at a reduced cost to their employees.
Naturally Slim is a year-long diet program based on mindful eating and healthy lifestyle changes. On the program, no foods are off-limits, and there’s no tracking required. It’s fully online and costs $37.50–$50 per month.
Some research supports the effectiveness of Naturally Slim for weight loss.
One large study including over 3,800 people who did the Naturally Slim program for 10 weeks found that women lost about 9 pounds (4 kg) and men about 13 pounds (6 kg) during the duration of the study (
Another study looking at Naturally Slim data from over 140,000 participants observed that women and men lost approximately 2% and 2.4% of their body weight over 10 weeks, respectively (
Note that this study was conducted by an employee of the company and one of its paid consultants, which may have biased the results.
However, there’s also some research to support the use of mindful eating principles for weight loss.
One review of nine studies on mindful eating and weight loss noted that mindful eating interventions resulted in more weight loss than no interventions, as well as that they could result in similar weight loss as a commercial diet program (
Two studies on Naturally Slim have shown impressive weight loss results among participants. Still, one of these studies may have been influenced by the company’s involvement. Mindful eating also appears to be an effective weight loss strategy.
Naturally Slim may also benefit people with metabolic syndrome and type 2 diabetes.
Metabolic syndrome is characterized by high blood pressure, insulin resistance, poor blood sugar control, excessive abdominal fat, and high blood fat levels (
People with metabolic syndrome are more likely to have overweight or obesity and be at a greater risk of developing type 2 diabetes or heart disease (
Still, one study in over 3,800 people on the Naturally Slim program noted that the percentage of women with metabolic syndrome dropped from 43% to 30% after 10 weeks, while the percentage of men with metabolic syndrome dropped from 52% to 26% (
Note that this study was conducted by researchers who have since accepted paid positions or consultancies with Naturally Slim, which may have biased the results.
Nevertheless, this data shows that Naturally Slim and mindful eating practices may help improve metabolic syndrome and decrease a person’s risk of type 2 diabetes.
Naturally Slim may help reverse metabolic syndrome and reduce your risk of type 2 diabetes, although the study that found this may have been influenced by the company’s involvement.
The biggest downside of Naturally Slim is its price, which may hinder some people from being able to use the program. Paid annually, it’s much less expensive but a higher out-of-pocket cost.
However, if you’re interested in trying the program, it may be a good idea to try to sign up during a sale. Alternatively, just try a month or two (paid monthly) to see whether it’s right for you before committing to an annual purchase.
Additionally, there’s little information about the long-term weight loss success of Naturally Slim participants. More research should be done on whether people are able to maintain their weight loss after the year-long program is complete.
Naturally Slim can be expensive, especially for the full year of programming. Additionally, little is known about the long-term weight loss success of program participants.
Overall, Naturally Slim is a good option if you’re interested in trying a commercial weight loss program. It teaches you mindful eating tools and principles that you can use well into the future to help you make better food decisions without having to track your intake.
While weight loss is not a guarantee, the program appears to help its participants lose weight. Naturally Slim may also help reverse metabolic syndrome and reduce your risk of type 2 diabetes.
However, little is known about the long-term weight loss success of Naturally Slim participants.
Naturally Slim is a balanced weight loss program that focuses on the principles of moderation and mindful eating, aiming to help you lose weight and change your eating habits for the long term. It appears to be successful for short-term weight loss as well.
Naturally Slim is a year-long diet program based on the principles of mindful eating and the foundations of a healthy and balanced lifestyle.
There’s some evidence to support the success of this diet and mindful eating as a weight loss strategy. However, more long-term follow-up is needed to see whether people can maintain their weight loss after completing the program.
Overall, Naturally Slim is a well-designed diet program that allows you to enjoy all foods in moderation and develop a healthier relationship with food.
