NativeMF — Native Metabolic Flexibility · A Physician-Guided Lifestyle Program
A proprietary 5-tier program rooted in hunter-gatherer physiology, designed to reverse chronic disease, optimize insulin sensitivity, and enhance longevity — for all ages and ethnicities.
Native Insulin Flex Score (NIFS)
Start Here — No Bloodwork Required
Answer a few quick questions about your body, activity, and habits — we'll estimate which of the five NativeMF tiers fits you best. Already have recent labs? Refine your result with bloodwork →
The NativeMF Protocol
Each tier is calibrated to your current metabolic health and progresses through dietary adaptation, time-restricted eating, and advanced exercise protocols over 9–40 weeks.
Three Pillars of NativeMF
An omnivore, ancestral diet eliminating seed oils and processed foods. Prioritizes grass-fed meats, wild fish, cruciferous vegetables, and seasonal fruits — exactly as the Dry Creek Pomo and other indigenous peoples ate before industrial contact.
Building skeletal muscle is the most powerful endocrine intervention available. Muscle tissue acts as a glucose sink without insulin, improving insulin sensitivity for up to 48 hours post-exercise. Our protocols progress from walking to full HRT + HIIT.
Living naturally and in harmony with the earth. Minimizing environmental toxicities — microplastics, BPAs, glyphosates. Optimizing sleep, sunlight, and mental wellness through BDNF-boosting protocols and cognitive behavioral principles.
Optional — For Those With Recent Labs

Our Mission
"Prevention through diet and lifestyle is the key to longevity and wellness."Thomas M. Elgin, MD — Board-Certified Emergency Physician, Dry Creek Pomo Nation
NativeMF was founded by Dr. Thomas M. Elgin, a board-certified Emergency Physician with over 25 years of clinical experience and a member of the Dry Creek Pomo Nation of Northern California. After decades of treating patients in acute life-threatening situations — many of which were the preventable downstream effects of metabolic dysfunction — Dr. Elgin turned his practice toward what the science increasingly supports: that chronic disease is largely a dietary and lifestyle problem rooted in the industrialization of food.
Indigenous peoples throughout the world maintained exceptional body composition and muscular endurance before European contact introduced processed foods, seed oils, and refined grains. Native Americans now lead nearly every chronic disease morbidity and mortality curve. NativeMF exists to reverse that trend — using physician-guided, evidence-based protocols that honor both ancestral wisdom and modern metabolic science.
The NativeMF program is available to people of all ages, genders, and ethnicities. Every protocol is designed as health coaching and lifestyle guidance. Individual medical conditions should be discussed with your personal physician.
Your Reason Why
Before starting the protocol, every patient identifies their own "reason why." These are the outcomes our patients most often name.
