Kamyar Kalantar-Zadeh (born November 11, 1963) is an American physician doing research in nephrology, nutrition, and epidemiology. He is best known for his hypothesis about the longevity of individuals with chronic disease states, also known as reverse epidemiology. According to this hypothesis, obesity or hypercholesterolemia may counterintuitively be protective and associated with greater survival in certain groups of people, such as elderly individuals, dialysis patients, or those with chronic disease states and wasting syndrome (cachexia), whereas normal to low body mass index or normal values of serum cholesterol may be detrimental and associated with worse mortality.
Kalantar-Zadeh received his undergraduate degree in medicine from the University of Bonn (Germany) and his M.D. degree from the University of Erlangen-Nuremberg (Germany). In addition, he obtained a master's degree in public health (Master of Public Health, MPH) and a PhD in epidemiology from the University of California, Berkeley. He is a practicing triple board certified physician specialist in internal medicine, pediatrics, and nephrology. Kalantar-Zadeh completed his residency at the State University of New York and his nephrology fellowship at the University of California, San Francisco.
