Affordable Doctor Visits That Focus on the Root Cause — Not Just a Prescription.

A simpler, lower-cost alternative to walk-in clinics for adults who want real answers: weight, blood sugar, blood pressure, energy, hormones, and metabolic health.

FitZone is lifestyle-first and root-cause focused. We aim to keep medications as low as medically appropriate by addressing what drives symptoms: nutrition, insulin resistance, inflammation, sleep, stress, and daily habits. Optional tools like CGMs and targeted labs help you see what’s really going on.

60 minutes • focused evaluation + plan
Labs optional • bring recent results if you have them
CGM coaching available +$50
Free FIZO Portal access after your visit

*Medications are used when medically necessary. Our goal is to reduce reliance by addressing root causes and improving metabolic health.

Why Weight Loss and Health Get Harder Over Time

Most people think weight gain, fatigue, rising blood sugar, or high blood pressure are separate problems. They’re not.

These issues are often connected by one root problem: your body becomes less efficient at handling food and energy. When that happens, everything gets harder — including weight loss.

Doctors often call this insulin resistance or metabolic syndrome. In simple terms: your system is out of sync — and the first step is knowing your baseline and following a medically sound plan.

When metabolism is off:

  • • Weight loss feels impossible
  • • Blood sugar and BP rise
  • • Medications tend to increase over time
  • • Energy and recovery decline

When metabolism improves:

  • • Weight loss becomes easier
  • • Labs can improve
  • • Meds are sometimes reduced (with your prescribing clinician)
  • • Energy and quality of life can return

What is the FIZO Health Score Portal?

The FIZO Health Score is a simple, structured way to understand metabolic health. After your visit, you get free portal access to help you learn what matters most and track progress.

  • Score + baseline: see where you are right now.
  • Labs & vitals tracking: follow changes over time with clear targets.
  • Education: learn insulin resistance, metabolic syndrome, and how food/sleep/stress affect results.
  • Action steps: practical next steps based on your baseline (not generic advice).

$50 Metabolic Health / Root-Cause Visit (60 minutes)

In one focused visit, Dr. Fitzmeyer evaluates what’s slowing your body down, sets a baseline, and gives you a clear plan. After your visit, you receive free access to the FIZO Health Score Portal for tools, education, and tracking.

Simple Pricing

$50 per visit. No memberships. No contracts. Add labs or CGM only if you want them.

Optional CGM Coaching

Add CGM setup / coaching +$50 to learn how food, stress, and sleep affect your blood sugar. (Device cost extra.)

Optional Labs

Bring recent labs if you have them. If not, we can discuss lab options. Testing is always optional and based on your goals.

What You Get After the Visit (Included)

FitZone is built for people who want root-cause answers—not a lifetime of “just take this pill.” Your visit creates a baseline and a plan. Then the portal helps you learn what to do and track results.

  • Baseline clarity: identify the biggest drivers of weight gain, high BP, and rising glucose.
  • Practical plan: simple steps and targets that match your history and goals.
  • Free portal access: tools + education to help you follow the plan correctly and measure progress.

The goal: make metabolic health understandable

The portal is designed to turn “confusing health advice” into a clear scorecard + targets. If you ever want additional medical support, you can schedule follow-ups as needed.

FIZO Health Score Portal (Example Dashboard)

Inside the portal, you’ll see your FIZO Health Score and the specific drivers that affect it (labs, vitals, and metabolic markers). You’ll also get education in plain English so you understand what insulin resistance is and what changes move your score in the right direction.

Our Medical Philosophy

Root-Cause First, Medications as Support

Food & Metabolic Strategy as Primary Medicine

Dr. Fitzmeyer focuses on metabolic nutrition and lifestyle strategies to improve insulin sensitivity, reduce inflammation, and restore metabolic flexibility.

Medications: Optional Support

When medically appropriate, medications (including GLP-1s) can be used as temporary support. The goal is long-term metabolic health—not medication dependence.

Goal: a clear, practical plan + portal tools to stay on track.

Optional Program

The FitZone 30-Day Metabolic Challenge

A physician-led, structured 30-day reset designed to help you kick-start weight loss, improve metabolic health, and understand your body — whether you work out regularly or not.

This Is Not Just for Gym Members

While many people join the challenge to support their workouts, the program is designed for any adult who wants clarity and momentum — even if you don’t exercise at all.

The goal is not to turn you into a gym rat. The goal is to identify metabolic roadblocks (like insulin resistance), give you real data, and follow a focused 30-day plan that actually moves the needle.

  • No gym membership required
  • Works alongside walking, home workouts, or no exercise
  • Focused on food, metabolism, labs, and habits — not workouts
  • Ideal for weight loss stalls or “nothing seems to work”

Think of it this way: your regular $50 visits are for ongoing care. The 30-Day Challenge is a guided reset for people who want a structured, short-term push with labs, education, and coaching included.

What’s Included

  • • Initial blood work focused on metabolic risk
  • • New patient physical & metabolic evaluation
  • • FIZO Health Score calculation & explanation
  • • Personalized nutrition & lifestyle plan
  • • CGM strategy and education (device options explained)
  • • 30 days of structured guidance & coaching

$249 one-time • 30-Day Program
