Naturally Slim Diet Review

Naturally Slim Review

The Naturally Slim Diet is not new to the weight-loss scene; it was founded in 1977 by CEO Marcia Upson. Their claim:

By improving people’s health, we’re able to improve the health of businesses, the economy, and an overtaxed healthcare system.

The program’s overall mission is to help a person “retrain” their brain about dieting and losing weight, and change their dietary habits without losing the pleasure of food and eating. There are no clinics; Naturally Slim is completely online.

Your employer may cover the cost of Naturally Slim—they partner with companies including Southwest Airlines, Michaels, Texas A&M University, Bigelow Teas, Oklahoma State University, as well as health systems like Genesis, Mercy Health, and BaylorScott & White. Naturally Slim also syncs up to Fitbit and Jawbone fitness trackers.

The cost for the individual program is $450, though Naturally Slim often offers discounts that drop the price to $385. Which sounds steep as a one-time payment, but this is for a year-long program (10 weeks plus 14 weeks plus 6 months). With no other food or supplements pushed on you by a “coach” or “personal consultant.” They also offer payment plans, though with those the total cost does go up: a 4-payment plan of $125 installments totals $500, and a 12-payment plan of $50 installments totals $600.

NOTE: There are no refunds. From the FAQ page:

Naturally Slim does not refund charges. Our team is available to help you work through any technical issues and our counselors are available to discuss any program concerns you may have. 

How Does The Naturally Slim Diet Work?

The curriculum involves videos to watch and dietary tips to follow. There are no off-limits foods—though there is encouragement to curtail sugar and processed foods, as the founders think it will do nothing but make your body more hungry. The online program instead tries to educate on how weight loss works and how to shift your mindset regarding food as a part of overall health and wellness. Curb snacking. Portion control. Staying hydrated. Get moving. Basic stuff: there’s little in the way of hoops to jump: no special foods to buy, no points to count.

In each phase of the program there will be a weekly video lesson. You will begin in our 10 week Foundations program, then move to 7 bi-weekly videos in our NS4You reinforcement program, and your year will finish with 6 monthly videos in our NS4Life maintenance.

While you’re not assigned a personal coach, the Naturally Slim program isn’t a solo operation, either.

You will not be alone through your Naturally Slim journey! As part of your dashboard you will have access to our exclusive online community NS Town. NS Town is a thriving community of diverse individuals learning the Naturally Slim lifestyle. Here you can interact with program counselors, alumni, and those new to the program to discuss and share your struggles and successes.

People who have gone through the diet said the overall premise of the program explains to eat only when you are hungry and always stay hydrated. Enjoying your meals and eating more slowly is also preached by the founders of the program, and they want the dieter to eat their favorite food on the plate first. They want you to understand that crash dieting is not the key to success; rather a change in your mindset and eventually your lifestyle.

Is The Naturally Slim Diet Safe?

This program is considered safe, yes, with no major red flags to the health and safety of the dieter. In fact, it’s not only safe but smart: portion control, eating more slowly, staying hydrated, and only eating whole and nutritious foods when you are hungry, are all the guidelines any nutritionist (not trying to sell a book, fitness gadget, or shake mix) is going to tell you. This is more of a lifestyle program, than an actual diet: it’s the slow lane, the smart lane, the lane most of us don’t have the patience to deal with despite the fact it works and it’s proven to work time and again. Naturally Slim does a great job marketing their model to large corporations in hopes that they will purchase a package for hundreds of employees—which is also smart, because a collaborative effort also works.

Pros And Cons Of The Naturally Slim Diet

There is nothing better than gradual weight loss that stays off, instead of quick weight loss that creeps back quickly. The Naturally Slim program teaches healthy habits so the dieter can see results over a long period of time, and hopefully keep that weight off.

According to a review at

Naturally Slim teaches you how to listen to your body and change your behavior about eating in ways that are not difficult, and don’t leave you feeling deprived.

The program also helps the dieter really tap into the details of all foods, both good and bad. The online format is convenient for working individuals who don’t have time to go into a clinic for weight loss.

The cons of this program basically come down to cost and commitment. If you’re doing it through your company, you have a support group built right in; a full year doing it on your own may be another matter. What you see is what you get—there are no additional packages, supplements, or other videos offered once you finish the program.

The Bottom Line

The Naturally Slim program is not a terrible idea, especially if your employer covers the cost. There is nothing wrong with educational videos, and advice on how to become a healthier version of yourself. You are not required to buy special food, supplements, nor are you promised an astronomical amount of weight loss in a short amount of time. The cost for an individual may not be appealing, though.

It is always a good idea to reach out to your health care professional first before you decide to try any weight-loss program. But Naturally Slim does seem to have the right idea.

My name is Lauren Jones and I come from a longstanding background of fitness and nutrition. I was born and raised in Boise, Idaho. Growing up, I played at the highest level of competitive tennis in the United States. I would travel both domestically and internationally to compete high level tournaments. With that, came a very disciplined regime of fitness and nutrition. I was given a full ride tennis scholarship to a Division 1 school, where I studied Journalism. After school, I went on to play professionally for two years. I love to incorporate health, and wellness in everything I do!
