#65 - Interactions between exercise and insulin with Professor Erik Richter

Sep 23, 2023
Professor Erik Richter, renowned authority in glucose metabolism during exercise, discusses how exercise increases glucose uptake and insulin sensitivity in muscle. They explore topics such as glycogen breakdown, effects of exercise on insulin levels in diabetes, and the role of AMPK in glucose uptake. The complexity of exercise and insulin interactions, benefits of continuous glucose monitoring, and the importance of physical activity in our sedentary lifestyle are also discussed.

Quick takeaways

  • Exercise increases insulin sensitivity in the muscle, improving glucose uptake and utilization.
  • High-intensity exercise can reduce appetite temporarily through various mechanisms such as lactate and hormone regulation.

Deep dives

Exercise enhances insulin sensitivity and decreases appetite

Exercise, whether it is high intensity or endurance training, increases insulin sensitivity in the muscle. High-intensity exercise can reduce appetite for a period of time after the workout. The mechanisms behind this are not fully understood, but it is believed that factors like lactate, lack fee, and the hormone GDF 15 may influence appetite regulation. Fasting and energy deficiency can lead to insulin resistance, while regular exercise promotes insulin sensitivity in the muscle.
