  • The Science of Fat

    The Science of Fat

    Lecture

    In the 2004 Holiday Lectures on Science, HHMI investigators Ronald M. Evans and Jeffrey M. Friedman discuss how the body regulates weight by carefully controlling the storage and burning of fat—and how a better understanding of these complex metabolic systems could lead researchers to treatments that curb obesity and improve public health.
