Ep. 76: Why Caloric Restriction Is NOT Responsible For Lifespan Extension (Hormesis Part 2)

In this episode we discuss:

• How the largest body of evidence cited in favor of hormesis actually doesn’t support it at all

• Why caloric restriction is NOT responsible for slowing aging and extending lifespan (and what is actually responsible)

• The many factors that confound the calorie restriction research (including differences between organisms, poor research design, amino acid restriction, PUFA, endotoxin, and more)
