Kamyar Kalantar-Zadeh
Kamyar Kalantar-Zadeh (born October 1963) is a
US American physician doing research in
nephrology,
kidney dialysis,
nutrition, and
epidemiology. He is best known as a specialist in kidney disease nutrition and
chronic kidney disease and for his hypothesis about the longevity of individuals with
chronic disease states, also known as
reverse epidemiology including
obesity paradox. 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 is also known for his expertise in
kidney dialysis therapy, including incremental
dialysis, as well as
renal nutrition. He is the brother of
Kourosh Kalantar-zadeh, who is an Australian scientist involved in research in the fields of materials sciences,
nanotechnology, and transducers.
