Summary

Dr. Michael Kaplan, DO, is one of only about 500 physicians in the United States board-certified in Obesity Medicine—a specialty dedicated to the medical management of excess weight and its metabolic consequences. Since founding the Long Island Weight Loss Institute in 2001 (with offices in Smithtown, Amityville, and East Meadow), Dr. Kaplan has focused on diagnosing and treating obesity as a chronic disease, helping patients with conditions such as metabolic syndrome, type 2 diabetes, hypertension, fatty liver, and dyslipidemia. He and his team work with most major insurance plans to ensure medically supervised weight-loss services—ranging from comprehensive metabolic panels and hormonal assessments to personalized risk stratification—are accessible and affordable.

Dr. Kaplan’s treatment programs center on an individualized, physician-led counseling system that he pioneered and which is now used in more than 450 practices nationwide. Each visit begins with a detailed body-composition analysis (fat, muscle, and water) to track progress and guide therapy. Patients receive tailored behavioral-therapy modules—focusing on meal planning, mindful eating, and cognitive strategies—and may choose full or partial meal-replacement regimens. When appropriate, prescription appetite suppressants are incorporated to enhance fat loss while preserving lean muscle mass. Exercise prescriptions, supported by print-friendly progress reports, encourage strength training and aerobic activity to sustain metabolic rate and prevent rebound weight gain.

Dr. Michael Kaplan’s credentials include a BS in Psychology (summa cum laude, University of Miami), a DO from New York College of Osteopathic Medicine, and board certification in Internal Medicine (ABIM). After residency and attending-physician roles at North Shore University Hospital and North Shore Medical Associates, he dedicated his career to obesity treatment. As founding partner—until 2014—of the Center for Medical Weight Loss (CMWL), he developed their core program and patient materials, and co-authored a 2012 American Journal of Medicine study showing an average 11.1% weight loss at 12 weeks among 500 patients. Today, through the Long Island Weight Loss Institute, Dr. Kaplan continues to refine medical protocols and deliver evidence-based care that emphasizes long-term weight maintenance and improved health outcomes.
