About our founder
Why serious coaches trust Sam with their careers
Sam Miller is an Amazon best‑selling author, Board Certified Health Coach, and Licensed Drugless Practitioner who’s spent the last 18+ years in the trenches of hormones, metabolism, and lab work. He’s built a reputation for turning complex physiological and biochemical concepts into simple, repeatable systems coaches can actually use with clients.
His workshops, seminars, and classes have served over 5,000+ coaches worldwide. He’s been invited to teach for Fortune 500 companies like LinkedIn and featured by industry leaders such as T‑Nation, Elite FTS, Muscle for Life, Mark Bell’s Power Project, Muscle Intelligence, and Barbell Shrugged.
FNMS is the culmination of that work – the mentorship he wishes he had when he was a “good coach” trying to become the go‑to functional expert.
How to join FNMS (and what happens after you apply)
If you’re accepted into FNMS, we want to be sure it’s the right move for your clients, your business, and your season of life. Here’s how we do that:
Speak with a Graduate
A no‑pitch call with a real FNMS graduate, no credit card required.
We’ll match you with someone whose coaching path looks like yours, so you can ask exactly how FNMS impacted their clients, confidence, and business before you make any decisions.
Career Mapping
If it looks like a fit, you’ll meet with our team to map your goals, current client load, and schedule.
We’ll walk you through how FNMS would fit into your life and be honest if we don’t think now is the right time. If it’s not a fit, we’ll make a referral.
Personal Onboarding
If you’re invited in and choose to enroll, we’ll walk you through a 1:1 onboarding to get started.
We cap intake at five coaches per week so onboarding stays personal. Last year we received over 890 inquiries and nearly 500 applications, so seats are limited.
Still Wondering If It’s Right For You?
DO I NEED A SCIENCE DEGREE?
We’ve had health coaches, PT's, nutritionists, gym owners, nurses/PA’s, and RDs all go through FNMS successfully. The curriculum is designed to be accessible but comprehensive—with support to help you master complex topics regardless of where you're starting by granting you access to our FNMS “First Steps” which serves as primer education to get everyone on the same page going into the live experience.
WILL THIS HELP IF I AM ALREADY CERTIFIED?
Yes. In fact, most FNMS students already hold multiple certifications. They don’t join because they need more letters – they join because they still feel gaps in their confidence, clinical reasoning, and client outcomes.
FNMS is built to take you from “I know the information” to “I know exactly what to do with this complex case in front of me.” We focus on labs, hormones, gut health, and metabolism, plus how to turn that expertise into better retention and premium pricing.
If you already have a foundational certification and you’re tired of stacking more theory without changing how you coach, FNMS was built for you.
WHAT IF I MISS A LIVE TRAINING?
Most of our coaches are juggling clients, families, and full schedules, and many join us from different time zones. You do not have to attend every call live to be successful.
FNMS is a multi‑instructor program with on‑demand replays and a streamlined community hub.
You can watch key trainings on your schedule, ask follow‑up questions in the community, and bring real client cases to future calls.
Most coaches complete FNMS while working full‑time. We’ll help you build a realistic plan during your kickoff so the program integrates with your life instead of taking it over.
IS FNMS ACCREDITED?
Yes. FNMS is the only live functional nutrition and metabolic health mentorship accredited by two leading health organizations. We also serve as a CEU provider for over five major industry organizations, including NSCA, NASM, AFAA, canfitpro, and more.
Most functional health certifications in the market have no external accreditation at all, or at most one, and are built around pre‑recorded modules. FNMS was intentionally designed as a live, case‑based mentorship that meets the standards of multiple independent organizations and third-party review.
When you earn your FNMS credential, you’re not just adding random letters – you’re signaling to clients and colleagues that you’ve completed a rigorous, externally recognized specialization in hormones, gut health, and metabolism.
HOW SOON CAN I EARN MY CREDENTIAL?
On average students earn their credential in 24 weeks. While some students have earned their credential in as little as 12 weeks, this will depend on your student path and trajectory outlined during your individual program kickoff with our team.
WHAT ARE THE PRE-REQUISITES?
While FNMS doesn’t require a formal degree, we do strongly recommend that applicants have at least one past course, certification, or credential in a related field. Whether that’s personal training, nutrition, health coaching, or another health or wellness discipline. If you’ve worked with clients, have a foundational certification, and are ready to take your skills to the next level, we built FNMS for you. If you have that initial baseline experience you do not need to do 3 more programs to “get ready” for FNMS. This would be a poor use of time and money.
IS THERE A PAYMENT PLAN?
Yes—FNMS offers multiple payment plans to make the program more accessible. Whether you prefer split payments or want to save with a pay-in-full option, we’ve got options to meet you where you are financially. If your application & interview aligns with our program expectations you’ll receive a variety of options to suit your needs. With that said won’t sell you something you don’t need. Taking the wrong coach’s money isn’t worth jeopardizing our industry leading reputation.
WILL THIS WORK FOR MY SPECIFIC NICHE / CLIENTS?
FNMS is physiology‑driven, not niche‑locked. We’ve had coaches specializing in women’s health, weight loss, physique, athletes, gut health, metabolic issues, and general population all use the same frameworks successfully.
Because we focus on hormones, gut health, metabolism, and lab interpretation, you’ll be able to apply the same principles whether your clients are busy moms, competitors, high‑stress professionals, or gym members who feel “stuck” despite doing everything right.
On your application and calls, we’ll ask about your niche and current clients so we can be honest about how FNMS would apply in your specific situation.
What is the FNMS Program? The Functional Nutrition and Metabolism Specialist (FNMS) program by Metabolism School is a 24-week, dual-accredited certification and live mentorship. It is designed for existing health coaches, personal trainers, and medical practitioners who want to master complex client cases involving hormones, gut health, and metabolic adaptation. Unlike standard textbook courses, FNMS focuses on experiential learning through real-world case studies and teaches coaches how to integrate lab testing with nutrition and lifestyle interventions. The program is delivered through a hybrid model of on-demand curriculum and weekly live small-group mentorship calls. By completing FNMS, coaches gain the clinical confidence to deliver superior client results and the business frameworks to establish premium pricing and industry authority. To join, applicants must complete a brief survey and schedule a no-pitch enrollment mapping call to ensure the program is a fit.
READY TO BRIDGE THE GAP?
Inside FNMS, you’ll learn how to confidently connect the dots and go deeper. From the average gen pop client to the more complex stuff — hormones, gut, metabolism — even the cases most coaches avoid.
And if you’re wondering, “What if I still don’t feel confident after?” — here’s the deal:
If you are in the program and can't solve a client's case, we’ll work with you and coach the case with you until you do. No extra fees. No fine print. Just real support. Guaranteed, as our promise to you.
