A Holistic, Medical Approach That Works
Our Integrative Weight Loss model blends functional medicine with medical supervision — combining advanced diagnostics, personalized nutrition, and targeted therapy.
It’s designed for patients who want more than a quick fix: individuals seeking the root causes of weight gain and sustainable, evidence-based results. Every patient begins with a comprehensive medical evaluation, including:
- In-house laboratory testing and metabolic panel
- Hormone and thyroid assessment
- Body composition scan (BIA)
- Lifestyle, stress, and sleep analysis
Your program may include clinical treatments such as GLP-1 support, nutrition therapy, and behavioral coaching — each prescribed only when medically appropriate
