In this episode, we delve into the misconceptions surrounding cortisol, the so-called “stress hormone,” and its relationship with weight gain, high-intensity workouts, and fasting. We aim to challenge the widespread belief that stress is always detrimental to our health by exploring how it can actually lead to improved body composition and resilience.
Topics include:
• The background and functions of cortisol in the body.
• The actual relationship between cortisol and weight gain, dispelling the notion of spontaneous weight gain due to stress.
• How high-intensity exercise, contrary to popular belief, does not cause chronic cortisol elevation and can improve body composition.
• The effects of fasting on cortisol levels and its impact on fat mass, lean mass, and overall body composition.
• The role of cortisol in muscle mass and the nuances surrounding workout intensity and duration.
