S 889: Knowing Better vs. Doing Better: Understanding Your Brain’s Resistance to Change

About this episode

This episode explores the gap between knowledge and action, discussing the cognitive processes that influence behavior and the emotional challenges that accompany change.

Most of us live with a frustrating gap between what we know and how we actually live. It is not a lack of information or a character flaw. We discuss the two systems governing our behavior. We move past the myth of willpower as a depleting muscle and look at it as a matter of cognitive bandwidth. This conversation names the human experience of shame and self-judgment that often follows a lack of action, offering a more honest way to understand why bridging the gap is so difficult. Topics discussed: - Frustration of knowing better but not doing better - Why more information is rarely the solution - Intentions vs. action - Two systems in the brain - Moving past the willpower depletion myth - How stress and interruptions crowd out new, effortful processes - The emotional discomfort - Mental contrasting ---------- ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠My Live Program for Coaches: The Functional Nutrition and Metabolism Specialization ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠www.metabolismschool.com⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ---------- [Free] Metabolism School 101: The Video Series ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠http://www.metabolismschool.com/metabolism-101⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠…
