In this Medical Society member showcase, Dr. Luke Palmisano, an emergency physician and MetFix affiliate owner, explains his approach to improving metabolic health and preventing chronic disease through lifestyle intervention and biomarker analysis. Drawing on his experience treating metabolically unhealthy patients in the emergency department, he developed a “metabolic health consult” that combines detailed nutrition and lifestyle logging with blood biomarkers to generate individualized health reports. His framework centers on six pillars of health—nutrition, exercise, sleep, stress management, relationships, and microbiome health—with nutrition and metabolic regulation playing the largest roles in chronic disease prevention.

A central concept in his work is metabolic flexibility—the ability to efficiently switch between burning glucose and fat—which he argues is impaired by chronically elevated insulin levels. Through targeted markers such as fasting insulin, DHEA, triglycerides, HDL, and thyroid indicators, Palmisano evaluates metabolic function and recommends lifestyle changes along with targeted supplementation. His overall philosophy is that metabolic health can be improved not through drastic interventions, but by carefully measuring key inputs—nutrition, sleep, exercise, and stress—and making small, strategic adjustments that move the body back toward efficient metabolic function.
