Judith Foster: How Our Bodies Use Food as a Fuel to Extract Energy and Maintain Weight. What Can Go Wrong?
One of the major health concerns in modern, industrialized nations is the alarming increase in both average body weights and obesity, especially among children. In order to understand how an increase in body weight relates to dietary intake and life style, this lecture reviews the molecular basics of how energy is stored in food and how it is transformed in our bodies to sustain our basal metabolic rate, body temperature, and physical activity. Discussion includes the classes of molecules that comprise different food types and their unique effects on metabolic pathways despite having similar caloric amounts. Dr. Foster is an Emeritus Professor of Biochemistry at Boston University School of Medicine. She recently moved to The Commons in Lincoln from Brookline, MA.
