#405 ‒ AMA #88: Metabolic liver health: how to assess risk, catch dysfunction early, and prevent or reverse liver disease

The liver serves as the metabolic headquarters of the body, acting as a critical regulator of glucose, fat, and cholesterol. Metabolic dysfunction often manifests in the liver through a four-stage progression: initial metabolic stress, steatosis, steatohepatitis, and eventually irreversible fibrosis. Visceral fat significantly exacerbates this process by draining directly into the portal vein, increasing the liver's metabolic burden. While fructose uniquely drives *de novo* lipogenesis, total caloric excess remains the primary driver of liver fat accumulation. Skeletal muscle acts as the body's largest glucose sink, making resistance training a non-negotiable intervention for preventing or reversing metabolic liver disease. Ultimately, liver health is inseparable from systemic metabolic health, as the liver's failure to regulate energy substrates drives insulin resistance and cardiovascular disease throughout the entire body.
