Dr. Ramsey has been exploring mechanisms that contribute to aging. In this presentation, he shares the results of his work regarding these issues. He explains that, overall, his research indicates that the first part of the question – can calories change the rate of aging – may, indeed be true.  As for dietary fat, the verdict is out. Regarding humans, Dr. Ramsey notes that increased lifespan over the centuries is not from lessening the basic effects of aging specifically, but rather is mostly due to improvements in hygiene and improvements in the treatment of infectious diseases.  It is his hope that a deeper understanding of aging processes will help with medical treatment of the elderly.
