The clinical program for the management of obesity at the UNCH medical weight Center is based on the principles embodied in the research and education endeavors. Strategies for treatment are based on leveraging heterogeneity of response to treatments and the use of multimodality options as appropriate for the degree of health impairment caused by the individual’s obesity. The strategies build on the resources already present in the UNC medical community to make a truly integrated program for the local patient population.

Dr. Machineni’s research examines mechanisms of energy balance and body fat regulation, determination of predictors for heterogeneity of response to obesity treatments, and clinical trials of new anti-obesity medications

Prior to coming to the University of North Carolina Chapel Hill, Dr. Machineni studied energy balance and body fat regulation in animal models with genetic, nutritional and bariatric surgical manipulations allowing the interpretation of clinical research findings and phenotypes in the context of physiology.  Drawing on this experience, he will focus on building a multi-disciplinary clinical research program to explore heterogenous patient response to obesity treatments and help develop personalized obesity medicine strategies incorporating genotypic, metabolomic and microbiota signatures. To date, Dr. Machineni is the only physician with a Castle Connolly distinction for obesity medicine in the Triangle area.
