Summary
On episode 367 of 40+ Fitness, Coach Allan sits down with Dr. Gus Vickery, a board-certified family doctor with extensive clinical experience helping people manage their health, to talk about his book Authentic Health: The Definitive Guide to Losing Weight, Feeling Better, and Mastering Stress.
Gus argues that information alone rarely changes behavior. When people are overwhelmed by chronic stress, the part of the brain that plans, weighs choices, and thinks long term shuts down, while the craving for a quick fix, food, nicotine, or alcohol, gets louder. Until stress is addressed, nutrition and exercise advice has nowhere to land.
The conversation covers his biopsychosocial model of health, why chronic weight gain is a hormonal cycle rather than a personal failing, and his practical protocols for both intermittent fasting and managing cravings.

Key Takeaways
- The biopsychosocial model says health is never just biology. Mind, body, and social and cultural environment all directly shape our physiology, our habits, and our experience of health, not just our nutrient intake or exercise routine.
- Chronic stress shuts off the “higher mind.” When someone is running on constant fight-or-flight adrenaline, the part of the brain responsible for planning and aligned choices gets inhibited, which is exactly when the desire for a quick fix is strongest. That is why stress has to be addressed before other health advice can actually be used.
- Weight gain is a cycle, not a character flaw. Most chronic weight problems trace back to exposures early in life that were outside a person’s control. Blame and shame add more stress, which undermines the very effort needed to change, so understanding the cycle comes before trying to break it.
- Eating too frequently keeps the body in fat-storage mode, regardless of what you eat. Whole, natural foods combined with balanced periods of feeding and fasting allow the brain’s weight-regulating center, what Gus calls the lipostat, to reset downward over time.
- Start fasting small: a 12-hour overnight window. Just skipping the after-dinner snack and breakfast until 12 hours have passed is enough for most people to begin. Build patience toward 14 to 18 hours, stay well hydrated, do not force a fast around a birthday or holiday meal, and eat normally, even robustly, on non-fasting days.
- Cravings are feelings, not thoughts, so willpower alone will not beat them. Gus teaches a four-step approach adapted from an OCD treatment method: detect the craving, relabel it as a “rogue brain circuit” rather than a personal failing, then refocus into a substitute activity, like a 15-minute walk, that delivers the same sense of well-being.
- Call it stress mastery, not stress management. Detect physical or emotional stress signals early, interpret the situation realistically instead of spiraling into catastrophic thinking, then use breathing or meditation to activate the parasympathetic nervous system and calm the body down.
- Gus’s three strategies to get and stay well: start with a mindful, deep desire for health, happiness, and fitness, built into a vivid mental picture, so the right choices follow naturally; play the long game instead of chasing a six-week fix, aiming to be about one percent better each day for the rest of your life; and honor your circadian rhythm through consistent sleep, natural daylight, and less screen time.
“Craving isn’t a thought. It’s a feeling. And feelings are more powerful than thoughts.”
