In this episode, Dr. Kashey talks about the concept of stress, particularly chronic stress, and its relationship with frustration. He explains that stress is a biological response to perceived threats or demands, rather than the cause itself. Dr. Kashey discusses how people often misuse the term "stress" to refer to stressors or frustrating stimuli, which can lead to emotional disturbances and subsequent biological stress responses. He introduces the STFU (Stimulus, Thinking, Feeling, Urging) model to illustrate how frustrating stimuli can trigger a cyclical interaction between thoughts, feelings, and urges, potentially leading to a stress response. Dr. Kashey emphasizes that chronic stress often arises when individuals engage in "double trouble," where they interpret practical frustrations as emotional disturbances and threats to their safety, perpetuating the stress response.

In this episode, Dr. Kashey talks about the concept of frustration and annoyance, and how they can lead to anger if not managed properly. He explains that frustrations arising from the operational domain (being able to do what one wants) and the fairness domain (getting what one deserves) are particularly prone to causing annoyance. Dr. Kashey discusses how annoyance generates a sense of urgency, leading people to act impulsively and irrationally, often escalating the situation instead of resolving it. He uses the STFU (Stimulus, Thinking, Feeling, Urging) model to break down how frustrating stimuli trigger thoughts, feelings, and urges that can spiral into anger and violent fantasies. Dr. Kashey emphasizes the psychobiological connection between these violent thoughts and the body's stress response, preparing for a fight. He suggests approaching frustrating situations as puzzles or games, creating a motivating challenge rather than a perceived attack, and learning from mistakes to update strategies for the future.

In this episode, Dr. Kashey talks about the rationale behind gradually increasing calorie intake during a fat loss phase, rather than continually decreasing calories. He explains that initially starting with a very low calorie intake allows individuals to improve their skills in measuring, tracking, and reporting their food intake accurately. As the fat loss phase progresses, calorie intake is increased, which creates a more psychologically and physiologically satisfying approach to fat loss. Dr. Kashey highlights that when an individual carries more body fat, it is easier to tolerate lower calorie intake, whereas as body fat decreases, hunger and the desire for more food increases. By structuring the fat loss phase to provide the highest calorie intake at the leanest point, it becomes more sustainable and reduces the risk of binge eating or regaining lost weight. He also suggests that this approach may be more hormonally healthy, promoting thermogenesis and improving the calorie-to-body-fat ratio for future fat loss phases.
