In this episode my guest is Satchin Panda, PhD, professor and director of the Regulatory Biology Laboratories at the Salk Institute for Biological Studies. We discuss his lab’s discovery that time-restricted eating (TRE), also known as intermittent fasting, has beneficial effects on metabolic health and longevity. Dr. Panda explains how TRE, and longer fasts as well, can positively impact obesity, diabetes, cardiovascular health, age-related chronic diseases and improve mood and cognitive performance. He also describes how the timing of eating, light exposure and exercise that roughly 50% of people engage in negatively affects their health, and he explains how simple adjustments to these factors can improve their subjective sense of wellbeing and biomarkers of cardiovascular function, glucose regulation and metabolism. We discuss how our circadian behaviors, which include patterns of eating, sleeping and socializing, have an enormous impact on our biology, mood and health, and how confining calorie consumption to a semi-regular daily window can enhance physical health, mental health and longevity.
