A Skeptical Look at the
NutriMost Fat Loss System

Stephen Barrett, M.D.

The NutriMost Ultimate Fat Loss System was developed by Ray Wisniewski, D.C., a chiropractor who practices in Murrysville, Pennsylvania and travels around the country to market the system to other chiropractors. In January 2016, it the program was available through about 185 clinics, most of which were operated by chiropractors. The NutriMost Web site claims that the Ultimate Fat Loss program "is designed to help keep your hormones in the very narrow Ultimate Fat Burning Zone" and that "The typical results are 25 to 45 pounds of fat loss in a mere 40 Days!" [1] The site also claims that the program (a) "virtually melts away" fat, (b) targets difficult-to-lose fat areas, and (c) does not require exercise, strenuous dieting, or radical changes in life style [2]. I am very skeptical of these claims.  

The NutriMost System is centered around use of a ZYTO device, which uses a hand cradle (pictured to the right) that relays low-voltage signals to and from a computer that runs proprietary software that recommends products. Its manufacturer, the ZYTO Corporation of Orem, Utah, states that the software "sends stimuli to the body using digital signatures that represent actual things" and interprets fluctuations in skin resistance that indicate "the body's degree of preference for the items being assessed." [3] I do not believe that skin resistance and the other data generated by the ZYTO have any practical health significance [4].


ZYTO's hand cradle has FDA 510(k) clearance for the purpose of measuring galvanic skin response (the skin's resistance to the passage of electrical current). [5] However, the computer component of the ZYTO system that "interprets" the measurements is not cleared or approved for diagnosing anything, identifying "toxins," preparing medications, or providing data relevant to weight-reduction. Nor, as far as I can tell, have the claims made for it ever been supported by a scientific study published in a recognized journal [6]. In May 2015, the FDA warned ZYTO Corporation that it was illegal to promote its ZYTO hand cradle for use in diagnosing a disease or condition or predicting biological responses to a wide range of virtual stimuli including drugs and nutritional supplements [7].

Wisniewski, who calls himself "the Weight Loss Answerman," claims that excess weight is caused by the accumulation of "toxins" in body fat and that the ZYTO prepares and imprints "energetic resonant frequencies" into customized formulas that "tell your body's cells "how to more effectively detoxify." The recommendations are embodied in a colorful report given to the patient, which states:

Utilizing the latest developments in cellular biocommunication technology we are able to "listen" to the body—to determine what supplements and the exact amount of each supplement that the body has a biological preference for which tremendously aids our decision making to attain the best results for long lasting and permanent targeted fat loss.

Here's how it works; Using the most advanced technology with the NRF (NutriMost Resonant Frequency) biocommunication technology, the computer sends a signal to the body in the form of a virtual stimulus, your body responds with very subtle changes in the electrical properties of your skin and the hand cradle measures these changes and sends that information back to the computer; it's like the computer's asking your body a question and your body's answering. . . .

Utilizing NRF Technology and the NutriMost Ultimate Fat Loss scan we now have the technology to assess the factors of fat burning, fat storage and fat metabolism. Including the organs involved, the hormones, neurotransmitters, vitamins, minerals, toxins, heavy metals, parasites, bacteria, viruses, mycoplasma, candida or biotoxins.

Our goal with this scan is to create a personalized and customized plan that will address your body's top organ stressors as well as finding the best products to balance those biological stressors. All weight gain involves imbalances within the body's organs and hormones. To have lasting and permanent weight loss we must correct these organ and hormonal imbalances. The NutriMost Ultimate Fat Loss Scan has been programmed to help give your body the nutritional tools that it needs to overcome these specific imbalances and to promote bringing the body into a very narrow hormonal range for optimum fat burning.

. . . . We expect to not only bring your body into the optimum fat burning zone but also balance and correct both the organ and hormonal stressors allowing us to go beyond weight loss and help you to actively create a lifetime of health [8].

These concepts are nonsensical. Obesity is not caused by toxins or infectious agents. Cells do not have "resonant frequencies." And ZYTO cannot "imprint" frequencies into products or "assess" anything related to obesity or body health.

The Better Business Bureau of Pittsburgh has given NutriMost LLC an "F" rating based on "advertising issues" and the company's failure to respond to seven complaints. In January 2013, the BBB asked Wisniewski to substantiate a long list of claims on his Weight Loss Answer Man Web site, including the "25-45 pounds in 45 days" claim mentioned above. The BBB report notes that he did not reply [9]. In May 2016, the main BBB site listed 54 other NutriMost businesses under separate names. Of these, 14 had "F" ratings and several reports noted that the advertising claims violated of the BBB Code of Advertising,

Wiesniewski has been teaching practice-building systems for many years. In 1992, in a chiropractic newspaper ad, he and a colleague stated that they each had been "serving" more than 1,200 patients per week and that chiropractors who attended their seminars would learn "how to get and process over 50 new patients in one day with just one doctor" and "how to make in the 7-digit range with 15% overhead." [10] From 2011 through 2014, he advertised an ""Automatic Robotic New Patient Income Generating Machine" that was promised to "bring in New Patients and sell products over the Internet all on autopilot." The system, which cost $3,800, contained videos, power point presentations. a patient communication system, a media distribution system, an "explosive" practice-building course, a service that answers patients' questions, the chiropractor's own store and Web site, and turnkey programs for diabetes, lupus, scleroderma, myasthenia gravis, multiple sclerosis, candida, biotoxins, lymes disease [sic], auto-immune conditions and weight loss 11].

People who have contacted me about their experience with a NutriMost practitioner have indicated that the program costs about $2,000 and includes:

  • The ZYTO scan. The scan reports I have seen identify (a) "top 5 out of range organs affecting fat loss," (b) "weight loss/fat loss product balancers," (c) "signatures for the detoxification formula," (d) "resonant frequencies in your energetic hormonal formula," (e) "top 7 vertebral stressors," (f) a "positive belief change affirmation," and (g) "preferred foods." These data have no science-based significance.
  • An 96-page manual that contains theoretical explanations, detailed instructions, and recipes.
  • A very-low-calorie "food plan" that supposedly causes the body to get into a "near perfect and exact fat burning state." The NutriMost manual claims that hunger will not occur because "appetite will naturally be suppressed by the 2000 up to 7000 calories of fat you will be burning dues to the weight loss program." The typical caloric intake is 500 to 800 calories per day with very little carbohydrate.
  • Weight-loss formulas prepared with the help of the ZYTO device. To ensure their potency, the directions say to "sucuss" them by tapping the bottle on the heel of the hand 8-10 times in rapid succession. The bottle marked "H 14" was said to have been customized for one of the patients who complained to me.

The sales process typically begins with a radio ad, a newspaper ad (see example to the right), or a lecture that invites people to undergo a free or low-priced evaluation. Although the ad may refer to the "technology" of the ZYTO scan, the device is not mentioned and the initial consultation is centered around being weighed on a scale said to determine the person's percentage of body fat and "metabolic age." In reports I have seen, the "metabolic age" number was much higher than the person's actual age. Several people have reported being very frightened when told that their metabolism was "like that of a 90-year-old." The ZYTO scan does not take place until after the full (nonrefundable) program is purchased. Most people who have contacted me have reported that during the sales process, they were not told that the calorie content of the diet was extremely low.

Practitioners typically offer a "discount" to patients who pay the full amount in advance and sign a contract which says that no refunds will be given. Recent contracts I have seen include provisions intended to protect the clinic owners from complaints. They say (paraphrased):

  • NutriMost does not provide any medical advice, medical treatment, or diagnosis.
  • The health information and materials given to the customer are provided with no warranty that they are fit to use. NutriMost does not assume responsibility for any errors.
  • The information provided is "not necessarily based on scientific or reliable tests or studies."
  • No product offered or recommended by NutriMost is intended to treat any medical condition.
  • NutriMost will not be liable for any type of damages the customer many incur by using the information, advice, services or products provided.
  • The customer agrees not to post any statements criticizing NutriMost through any online medium and agrees that any violation of this provision would make the customer liable for $35,990 in liquidated damages.
  • The customer agrees to waive any rights under any law that would limit the waiver of any such rights.

I don't know whether these provisions would be enforceable in court. I doubt that most people who sign this agreement understand what they are signing.

The NutriMost manual states that men typically lose between 35 to 45 or more pounds in 40 days, while women tend to lose 27 to 32, that the system "ALWAYS works," and that loss of 20 pounds is guaranteed. However, the "guarantee" is not a refund. The only thing available to those who fail is another 40-day cycle of the program—provided that they have kept all of their appointments, kept a diary, "followed the system and did not cheat and could show that." The NutriMost contract states that those who stop the program in less than 40 days because they feel ill or because it didn't work for them would not be eligible for a refund. However, several people have told me that their money was refunded after they threatened to complain to the chiropractor's licensing board, their state attorney general, and/or the Better Business Bureau and, if necessary, to file a lawsuit. To get a refund, some chiropractors require patients to sign a "release of claims and non-disparagement agreement" that prohibits them from discussing their experience unless compelled to do so by a subpoena, regulation, or court order. The agreements I have seen include a 2015 copyright notice from NutriMost Doctor's LLC. In 2016, many NutriMost sites reworded the guarantee this way:

*Although results may vary, those who follow the program typically have a very high success rate. NutriMost guarantees at least 20 pounds of weight loss by the end of your entire program. If you do not lose at least 20 pounds, you will have your program extended until the total weight loss reaches 20 pounds, with all associated costs paid by your NutriMost office. If within 90 days, you have not reached at least 20 pounds of weight loss while on the program, your NutriMost office will refund any amount from the cost of the program which you as the client deem to be fair up to the entire cost of the program.

It isn't clear whether people who unable to follow the program (for health reasons, for example) would be eligible for a refund.

If no immediate refund is offered, it may be practical to file suit under your state's unfair and deceptive acts and practices law [12], many of which enable plaintiffs to collect triple damages (or a substantial penalty) plus attorney fees.

The "Top 7 Vertebral Stressors" portion of the ZYTO scan reports that I have seen contains this paragraph:

Vertebral bio-markers that are showing stress in your body and quite likely sedating nerves. Our goal is to obtain optimal health, optimal fat loss and to reduce the stress of your body so that your innate healing ability can function at its best while reaching peak performance and fat loss. These vertebral stressors are most often associated with sedated nerves. Although the nutrients and formulas recommended will greatly support healing and correcting these vertebral biostressors, the problem is that no amount of nutrition can overcome a sedated nerve. These sedated nerves (subluxation) would need to be verified with a Parathermal Scan and advanced bio-structural corrective xrays and then a specific corrective Chiropractic regimen be undergone to correct any sedated nerves to restore optimal health and innate healing.

This type of message could be used to induce patients to have their spine examined and undergo a lengthy course of unnecessary spinal manipulation. However, none of the people who described their experience to me were invited to do this.

More than 60 NutriMost Web sites have content that is identical except for the details about the individual clinic. Most also contain "before and after" pictures the same six individuals who are said to have lost from 27 to 47 pounds on the program. I assume from this that the licensing arrangements include a pre-designed site that can be individually customized and that the six people were not clients of the clinics that display their testimonials. Searching with Google I found that at least 40 of these clinics contain this statement:

Although Dr. Ray has been traditionally trained a s a Doctor of Chiropractic, he presents and offers NutriMost services as member only services under his Pastoral Medicine License # L29076049. Dr. Ray is a Christian who believes that God created this body with an amazing healing power and that there is nothing outside the body, that is as powerful as the power that God put inside the body. Pastoral Medicine is the Professional Blend of Scriptural Health Wisdom and Understanding along with Leading Edge Science. The NutriMost services are pastoral health services and should not be confused with state regulated services.

I do not believe that the "licenses" issued by the Pastoral Medical Association (PMA) confer any legal right to practice a health profession [13]. I also believe that any service offered by licensed health professionals should be subject to regulation by their licensing boards, but only a few boards have addressed this issue. Some have ruled that PMA "licensing" does not convey the right to practice a licensed profession, but others have decided that if PMA-related activities are carried out as a separate business, they will not intervene. Several boards are considering complaints but have not yet ruled. Regardless of what the boards decide, I believe that state attorneys general have jurisdiction under state consumer protection laws.

Curiously, at least 14 of the chiropractors who offer NutriMost have been subjected to regulatory action at some point in their career and least three are no longer licensed as chiropractors [14].

Similar Clinics

Three companies in New York and New Jersey have been using NutriMost's name and/or sales materials:

NutriMost itself is being sued by Patrick St. Germain, D.C., who purchased what he believed to be the exclusive right to market in portions of Florida. The suit charges that Wisniewski and NutriMost Doctors LLC improperly enabled another chiropractor to open clinics in the same region [18]. The purchase agreement included licensing fees of $50,000 up front for the first four clinics, $15,997 for each of four more offices when opened, and $5,000 per month plus 3% of the monthly sales related to weight loss at all but one of St. Germain's facilities [19]. For at least two years, he has been doing business as Burn Fat Orlando with no mention of either NutriMost or Zyto on his clinic Web site.

Why You Should Be Skeptical

Diets that are very low in calories are not much different from total starvation and are dangerous. The U.S. Federal Trade Commission has determined that the claim that a product "safely enables consumers to lose more than 3 pounds a week for more than 4 weeks" cannot be true because that rate of loss can result in gallstones and other health complications [20]. NutriMost's recommended calorie intake could cause people to lose about 3 pounds of fat per week if they can actually maintain it, but NutriMost claims that more than twice this rate is possible. I don't believe it.

In sum, I do not believe that the ZYTO device, the weight-loss formulas, the dietary strategies, and the NutriMost Ultimate Fat Loss System as a whole can work as advertised. If you have used the NutriMost and would like to share your experience with me and/or discuss whether to seek a refund, please e-mail me a copy of your scan, a copy of your contract, a brief summary of what happened, and your phone number. I am also interested learning how former NutriMost clinic employees were trained.
