An internal look at the FDN’s “Test, Do Not Mession” approach and why graduates build six-arbitrary practices
The functioning area is full of professionals who promise to “get to the basic cause”. However, customers are often bouncing from one protocol to the next, spending thousands with little to show about it.
Reed Davis has a different story. After 10 years “thousands of workshops in thousands of people” in clinical practice, he noticed something: some customers became dramatically better, while others did not. The pattern was not accidental – it was methodical.
This observation became the foundation for the Functional Diagnostic Diet (FDN), which has now been trained by over 5,000 professionals worldwide.
From clinical frustration to pure methodology
Davis’ initial mission was simple: “My job when I started was to find out because someone was sick about the treatment or management of their symptoms.
These 10 years of practical work have revealed critical standards. “I ran thousands of workshops to thousands of people, and with great guidance. I made my own observations of who got better and who didn’t do it and developed a methodology from it.”
The discovery came when Davis realized the broader impact: “Finally, after 10 years, I realized the greatest impact that would happen if I could teach other professionals the model, the methodology.”
His mission crystallized: “To train people and professionals how to get well and stay well so they can train others.”

What “test, don’t guess” really means
The signature phrase of the FDN goes deeper than they simply perform laboratory tests. Davis explains the problem in the way most professionals approach the tests:
“Many people say,” Well, I have already tried. Yes, I run tests as well. “But assume which tests will run on the basis of symptoms.”
This creates what he calls “sounds like a method”. If the symptoms sound like thyroid problems, they perform thyroid tests. If it sounds like digestive problems, they try the intestine.
“So they use a sound method to determine which test will run. And therefore they do not get such a complete assessment.”
The result? “They will believe that they have found the problem and face the paper and hope that the person will do better, but if the person appears with new complaints … they will perform another test, so now in a new test cycle, face the paper, try, tackle paper, try.
The FDN adopts the opposite approach: “We insist on trying to identify multiple healing opportunities in the test phase.” Instead of chasing the symptoms, professionals are looking for causal factors that can be “very upstairs, far from where the symptoms occur”.
But the execution of multiple tests is not enough. “You must also notice how causal factors influence each other, creating a state of multiple metabolic chaos and so is more or less our work – to settle the metabolic chaos in search of multiple causal factors and healing opportunities.”
How FDN is different from other programs
When prospects compare the FDN with popular programs, Davis has clear discrimination:
“What we teach is how to get the data that will really lead a personalized program against a general program.”
It draws up competition: “These programs generally teach protocols, have a hundred diets, and I’m not sure they determine which diet for which person and most of them are more coaching … active listening and incentive strategies and ways to get people to do what they say.
“No one is still close to the FDN in terms of the operation of the laboratories, the data reception and the truly identification of the healing opportunities that a person needs to know.”
Focus on what Davis calls “biotomy and metabolic individuality” leads everything: “FDN protocols affect each cell, tissue, organ and system at the same time, so that people are simply good”.

Built in practical experience, not theory
Davis emphasizes that the FDN “is taught on the basis of practices, based on methodology” and not academic theory. The methodology “developed for a 10 -year period in an office that observing who got better and who didn’t do it”.
“We teach you practice, step -by -step methodology that works and starts with yourself and you work for yourself,” he explains. Students complete the program with personal experience using the protocols they will recommend to customers.
The structure reflects this practical approach: “It is a self-regulating course where you work for yourself as part of the learning process with a lot of one-on-one mentality.”
The claim of six numbers: Confidence based on results
Davis makes a bold statement about the potential of postgraduate profits: “We believe that if you don’t win 6 figures in your first 6-12 months, you do something wrong.”
His confidence comes from repetitive success stories: “I am very sure of that, because I have seen people do it again and again and again and have done it personally.”
In fact, he suggests that the potential is higher: “The six numbers must actually be multiple six numbers. So I can teach you how to make one hundred thousand dollars, which are six numbers every three months.”
This acquisition potential reflects the value provided by FDN professionals through data -based results. Davis teaches what he calls “a part -time work model and makes multiple six numbers in business … work from your own hours, working on your own hours from anywhere you have an internet connection.”

What separates successful graduates from competitors
Not every graduate achieves the same results. Davis attributes the difference to mentality and approach:
“I think their personal opinion and self -confidence and self -awareness and maturity and ability to handle … the ability to face challenges and their ability to face problems. And it’s all, for me, it’s all about self -knowledge and self -confidence.”
Racing practitioners often “trapped in what they cannot do” instead of taking action. His tips are immediate: “Just go out and apply the principles, go out and take a customer, help this customer and learn from it and take another customer and another customer and another customer.”
He notes that practitioners who are struggling to close the structure and logistics instead of helping people: “People who close throughout the structure, legal bodies and these things … do not take it.
Creating a practical waiting list
Successful FDN professionals understand that a practical waiting list requires professional limits. Davis explains:
“A waiting list means that you are adjusting yourself and tell people that they have to wait and make an appointment. You create some exclusivity around your availability.”
In practice, this means you never say “call me at all times” because “if you say, call me anytime, it means you have nothing to do. You are not busy and you do not create any responsibility anywhere”.
Instead: “You say, my hours are Monday, Wednesday and Thursday from one to five. How the next Wednesday in a sound to you? This creates some availability … that you are a professional and that you have hours.”
The key restricts appointments: “You will only have nine appointments a week.

Open the registration philosophy
Despite the price point of $ 12,997 of the program, Davis maintains a non -exclusion enrollment approach. When asked why the FDN accepts almost anyone, replies:
“Why will I turn anyone away? Is it the best question. Why will I turn a mother of three who just want to learn to take care of herself and her children? Why will I take her away?
Some students are writing “to learn the methodology for their own health and their families. And if they are all they do with education, they work for themselves and their families, it is worth the price of admission.”
But the ideal candidate is someone who “already has the clientele that they could exploit and raise their services, have better results, increase their reputation and increase revenue by adding these additional FDN services”.
The most successful? “The person who lifts his / her skills can graduate and usually has more success than someone who comes from a different background.”
Justifying the investment
When the prospects hesitate at $ 12,997 costs, Davis puts it in perspective:
“It’s an investment that will have an investment performance, roi, in a very short time. One can get their tuition tuition back … with very few customers who pay.”
It contrasts it with traditional education: “The only thing one could compare with fairly would be a two to three years training after training.
“I can teach you in 10 months what it took me 10 years to develop and this is remarkable. This is the deal if I have ever heard of one.”

What do graduates find out
During the postgraduate interviews, Davis listens firmly to something that surprises him:
“Everyone seems to be grateful that they could even learn it, as there is nothing available to them anywhere and they are just amazed that they should not go to college for six years or eight years.”
The revelation for many? “That there is a methodology, that there is a way that they can help others.
Many tell Davis that “the FDN was the answer they were looking for” and that “it ended this test cycle of test and error”.
Future vision and basic values
Looking forward, Davis has ambitious but clear goals: “We would like to see the next three, five years, 25,000 FDN professionals, certified and out of the world who do the good work.”
It is just as clear about what the FDN should never be done. His greatest concern? Excessive arrangement: “I would not want to be overly adjustable, such as professional institutional requirements.
This reflects his broader philosophy: “We want to keep handcuffs away from people.”

The bottom line
Davis summarizes the FDN: “FDN is a methodology and way of thinking that uses functional laboratory work – data from functional laboratory work – to identify healing opportunities so that people can deal with real underlying causes and conditions, what is really wrong, instead of dealing with it.”
After more than a decade of training professionals, Davis has created something specific: a methodology based on clinical experience that produces consistent results for both professionals and customers.
For health professionals who are tired of speculation and ready for a data-based system, this is not just education-it is a career transformation.
