The Comprehensive Weight Control Center (CWCC) is part of the Division of Endocrinology, Diabetes, & Metabolism at Weill Cornell Medicine. It is a center of excellence in the area of obesity evaluation and treatment directed by Louis J. Aronne, MD, Professor of Clinical Medicine and the Sanford I. Weill Professor of Metabolic Research. The goal of the Center is to take a multidisciplinary approach to managing patients with obesity, and to provide evidence-based, compassionate clinical care. The Comprehensive Weight Control Center (CWCC) is also dedicated to research in the field of obesity and type 2 diabetes and training physicians and students in the field of obesity medicine.


The medical team is composed of board-certified physicians with various backgrounds (Internal Medicine; Nutrition, and/or Endocrinology), registered dietitians, a family nurse practitioner/ diabetes educator who all work together to help patients lose and maintain weight loss through lifestyle intervention, medicine and surgical intervention if needed. 


Our Approach: 

Science has taught us that obesity is the result of numerous factors. It can also cause many health-related conditions; such as high blood pressure, high cholesterol, type 2 diabetes, cancer and arthritis. Our team provides an in-depth personal assessment to evaluate the source of our patients' weight-related issues. For example, where possible, we find solutions for medication-induced weight gain, and we evaluate for sleep disorders that can contribute to weight gain. We also address and manage weight issues associated with other chronic medical conditions, including disordered eating patterns related to craving and binging behaviors. In addition to behavioral strategies, we utilize medications and minimally invasive devices to assist in the weight loss process. Using the shared decision-making approach, which includes the patient, a personalized plan will be designed. 


Once the plan is established, we work closely with our patients to evaluate their response over time, and make changes as needed. Follow up is provided in person and also through technology such as remote patient monitoring, assessment, education, motivation, and support.
