About Joslin | Patient Care | Supporting Joslin
Osama Hamdy, MD, PhD, FACE is a senior endocrinologist, clinical investigator and Medical Director of the Obesity Clinical Program and Director of the Inpatient Diabetes Program at Joslin Diabetes Center. He is an Assistant Professor of Medicine at Harvard Medical School.
Dr. Hamdy is a co-investigator of 2 landmark studies; the National Diabetes Prevention Program and the Look AHEAD Study. The early clinical research of Hamdy's lab demonstrated that 7% of weight reduction improves endothelial function, insulin sensitivity and several markers of inflammation and coagulation in patients with type 2 diabetes and prediabetes. He translated his successful clinical research into a clinical practice model: the "Why WAIT" Program (Weight Achievement and Intensive Treatment), the world's first multidisciplinary clinical practice model for diabetes weight management in real-world clinical practice. Dr. Hamdy won the 2015 Michaela Modan Award of the American Diabetes Association for his research work that showed that participants in Why WAIT program were able to maintain weight loss for 5-years with improvement in several cardiovascular risk factors. Similar amount of weight loss was found to reduce total health care cost by ~27% and diabetes related cost by ~44% per year. Joslin is currently piloting a simplified version of the Why WAIT program at the YMCA community centers and developing a program for primary care settings. Dr. Hamdy outlined his Why WAIT research and clinical experience in his Harvard Health Publication book "The Diabetes Breakthrough".
Dr. Hamdy chaired the task force that developed the Joslin New Nutrition Guidelines and is active the member of the Nutrition Guidelines Committee of the American Association of Clinical Endocrinologist that created several guidelines for nutrition and obesity. He co-chairs the International Diabetes Nutrition Group that developed the Transcultural Diabetes Nutrition Algorithm (tDNA). Dr. Hamdy is currently conducting several research projects about the role of nutrition and particular nutrients on diabetes control and weight reduction.
