Who This 30-Day Challenge Is For

Whether you're trying to lose weight and get in shape, or you're already fit but concerned about hidden health risks, our physician-led metabolic challenge gives you the clarity and plan you need.

Want to Lose Weight & Get in Shape

You're training at the gym but hitting weight loss plateaus. You want to see real results from your workouts but need a metabolic tune-up to break through.

Training hard but not losing weight

Confused about diet and nutrition

Need data-driven approach to fat loss

Want to optimize workouts for results

Our Solution: Blood work reveals metabolic blockers, CGM shows food responses, and our FIZO-based plan gives you a 30-day roadmap to break plateaus and see real progress.

Fit Outside, Concerned Inside (TOFI)

You look fit but worry about hidden health risks. Muscle can mask metabolic problems until blood work and time reveal them.

Normal weight but high body fat percentage

Visceral fat around organs despite workouts

Insulin resistance hiding under muscles

Elevated cholesterol or blood pressure

Our Solution: We detect hidden risks early, explain your true metabolic health, and give you a 30-day plan to reverse insulin resistance and protect your long-term health.

Both audiences get the same comprehensive 30-Day Metabolic Challenge — just with different starting points and goals.

Start Your 30-Day Challenge

Are You TOFI? (Thin Outside, Fat Inside)

TOFI describes people who look fit in a T-shirt but carry dangerous visceral fat and metabolic risk on the inside. Gym members are especially at risk because muscle can hide the problem — until blood work and time reveal it.

The Hidden Danger for Gym Members

During your 30-Day Challenge, we don't just draw labs — we interpret them for you in plain language and relate them to your actual risk for future disease as you get older.

Normal weight but high body fat percentage

Visceral fat wrapped around liver and organs

Insulin resistance despite daily workouts

Elevated cholesterol patterns and cardiovascular markers

The challenge is designed to pick this up early and spell out clearly whether you're on track for good aging — or quietly drifting toward chronic disease — and then give you 30 days of focused action to start reversing it.

Check My Health Lose Weight Instead

Initial Blood Work & Complete Health Assessment

Your 30-Day Metabolic Challenge starts with a focused baseline panel and a new patient physical designed around metabolic health. We analyze your results to show where you land on the spectrum from healthy metabolism to insulin resistance, prediabetes, and early cardiovascular risk — and how that affects you as you age.

Initial Blood Work

Comprehensive baseline testing included — metabolic and cardiovascular markers that show your risk for insulin resistance, Type 2 diabetes, fatty liver, and heart disease as you age.

New Patient Physical

A full metabolic-focused physical exam: blood pressure, body composition discussion, waist-to-height ratio, and red flags for future chronic disease.

Complete Health Assessment

We connect the dots between your numbers, your symptoms, and your lifestyle and explain clearly how this affects your future risk if nothing changes.

30-Day Metabolic Challenge Plan

You'll leave with a written 30-day challenge based on your labs, your training schedule, and your FIZO Health Score so you're not just working out — you're actively fixing the root metabolic problem.

Diet Plan & Education

We build a low-carb to carnivore-style nutrition plan customized to your risk profile and goals, and explain exactly why it works based on your FIZO Health Score and blood work.

Coaching Based on FIZO Score

Your Health Coach uses your FIZO Health Score as a dashboard — helping you understand which markers matter most and what to focus on over the 30 days.

Whether your goal is weight loss or health optimization, this comprehensive assessment gives you the data and direction you need.

CGM Included in Your 30-Day Strategy

As part of your challenge, CGM (Continuous Glucose Monitoring) is built into your plan. We show you how to use a Dexcom CGM to see exactly how your body responds to meals, training, sleep, and stress — all of which drive insulin resistance.

Real-Time Feedback for Your Challenge

Instead of guessing, CGM gives you real-time feedback while you're doing the challenge. You'll see on your phone what your blood sugar does when you eat, lift, do cardio, or sleep poorly — and we connect that to your long-term risk.

Real-time glucose curves

See spikes, crashes, and stable periods instead of guessing from one lab number.

Food response decoding

Find out which "healthy" foods are brutal on your blood sugar and insulin and which meals keep you flat and steady.

Training optimization

Use CGM to dial in your pre- and post-workout nutrition and recovery to support long-term health, not just PRs.

How It Fits Into the $249 Program

CGM training, interpretation, and integration into your 30-Day Challenge are included. Device placement and duration can be customized and discussed transparently so you know your options and cost before you commit to extended CGM use.

The goal is not for you to live attached to gadgets forever — it's to learn your metabolic fingerprint, then follow a plan you can sustain.

Why a 30-Day Challenge?

Most gym members only hear, "Your labs are okay" or "we'll just watch it." That's not good enough. The 30-Day Metabolic Challenge was built specifically for active adults who want to know where they really stand — and want a medical plan, diet, education, and coaching to change the trajectory.

"Whether you're trying to lose weight or protect your health, if you're putting in the work at the gym, you deserve to know whether your blood work matches your effort — and you deserve a clear plan to fix it."

Your FIZO Health Score-Driven 30-Day Plan

This is not a one-size-fits-all challenge. We use your FIZO Health Score — built from your blood work and metrics — to personalize your diet, education, and coaching over 30 days.

Initial Blood Work & Physical – The raw data that powers your FIZO Health Score and risk analysis.
FIZO Health Score Calculation – A simple way to see if you're trending toward chronic disease or away from it.
Diet Plan Based on Your Score – Low-carb to carnivore strategy tailored to your labs, body, and goals.
Education – Plain-English explanations of what each key marker means for your future health.
Coaching Based on FIZO Score – Your coach uses your score as a roadmap to guide your 30 days.
CGM-Integrated Feedback – CGM data is layered on top of your FIZO Score so you can see real-time proof of change.
