What is MetFix: Part I

A Metabolic Problem Needs a Metabolic Fix

by Emily Kaplan


In this article, Emily Kaplan presents a clear, science-based explanation of what MetFix is and why it works—grounding the program in metabolism, mitochondrial function, and hormonal regulation. She describes how modern diets heavy in refined carbohydrates and seed oils distort fuel partitioning, driving fat storage, insulin resistance, and eventually organ dysfunction. MetFix counters this by pairing a low-carbohydrate, high-fat diet with Greg Glassman’s methodology of constantly varied, high-intensity functional movement—an approach that optimizes bioenergetics, restores metabolic balance, and builds functional capacity.

Much of this science underlies the MetFix Foundations Course already, but Emily lays it out here more directly: how energy systems dictate hormone responses, why mechanics must come before intensity, and how the right dietary inputs allow the body to burn fat, build muscle, and reverse chronic disease. These twin pillars—the nutrition and the training—create the metabolic environment in which the body can repair itself and thrive.
