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.

What Our Patients Are Saying

Talking about Louis J. Aronne, M.D.

"I have been overweight for years and were it not for having diabetes and coronary heart disease I wouldn’t be concerned. However, after 10 years of failing to lose weight, I sought the advice of a recognized leader in the field. I did not anticipate having a significantly different experience than what I had had in the past. I could not have been more wrong. Dr. Aronne started a regimen that included Plenity and Ozempic. In one year, I have lost 15% of my body weight and, as long as I remain true to my medical regimen and maintain a prudent diet (not excessively austere), I can hold steady at my target BMI. His comprehensive team approach works and both he and his staff have been reasonably available whenever the need has arisen. Whether it was a question concerning side effects or a change in the care provided by other physicians, the team had the answers I needed and never left me feeling rushed. I recommend his practice enthusiastically and without reservation."

Talking about Beverly Tchang, MD

"Dr. Tchang is one of the most compassionate, easy to talk to, leading experts in diabetes and weight management. As a woman of color that's had plenty of awful experiences feeling ignored or like my own experience was constantly minimized and reduced to excuses for poor behavior, she is a doctor who actually cares about hearing YOU. What your story is, what your experiences have been, what has worked and what hasn't and will curate a plan that works for you. It won't be the quick and dirty drop 15 in a week scheme that most weight loss fads offer - if that's what you're looking for this would be an expensive and ineffective alternative. No, on this plan, you will lose weight, very slowly, but consistently, and get your numbers under control once and for all. Most of all, it won't be a dread to try because you'll know your doctor is on your side and rooting for you."

Talking about Louis J. Aronne, M.D.

"Dr Aronne is a weight loss God! He helped me lose 100 pounds and with his continued guidance I have kept it off. Through-out the process I wasn’t hungry, at all. If you need to lose a lot of weight and don’t care to undergo bariatric surgery, this practice gets amazing results!"
