How Your Breath Affects The Way You Burn Fat, The Importance Of A Daily 45 Minute Walk (With Your Mouth Shut!), The Pros And Cons Of Nasal Breathing & The Five Gear Breathing System That Will Transform The Way You Handle Stress with Brian Mackenzie #547

Apr 15, 2025 1h 49m 39 insights
Your breath is intimately linked with every aspect of your health – from how you respond to stress to how efficiently your body burns fat. While most of us breathe over 20,000 times a day, few of us pay attention to this automatic process. But it may hold the key to transforming our physical and mental wellbeing. Today’s returning guest is the wonderful Brian Mackenzie, Founder & Creative Director of SHIFT, President of The Health and Human Performance Foundation and a world renowned human performance specialist who combines breathing techniques, movement practices, and stress adaptation training to enhance physical and mental performance.    His methods have been used by Olympic athletes, professional sports teams and military special forces and Brian's work has undergone rigorous scientific testing at institutions including Stanford University School of Medicine and San Francisco State University. He is also the author of several books including, Unbreakable Runner, Power Speed Endurance and Unplugged. In this fascinating conversation, we explore: Why breathing is "the remote control to the nervous system" and how becoming aware of our breath patterns can help us instantly regulate our stress responses  The relationship between the way that we breathe and our ability to burn fat The "Five Gear Breathing System" that matches our breathing technique to different activity levels, from relaxed walking to high-intensity exercise Why nasal breathing (while beneficial at rest and low intensities) might limit our performance and oxygen use during higher-intensity activities How a simple daily 45-minute walk with nasal breathing can transform our metabolism, stress resilience and mental clarity The three-stage stress response cycle and how breathwork provides a practical tool to interrupt our automatic reactions to daily triggers Why Brian believes finding joy in mundane tasks like washing dishes is possible when we focus on the process rather than constantly chasing outcomes Practical techniques to establish healthier boundaries with work, technology and stress – including Brian's approach to shutting off work by 4-5 pm and using red light in the evenings to improve sleep Brian is a remarkable individual, with an enviable track record of transforming the wellbeing and performance of a wide range of individuals, and this conversation is full of practical insights that you can utilise immediately to improve your health, performance and the overall quality of your life.

Actionable Insights

1. Confront Underlying Emotional Pain

Confront underlying emotional pain or past trauma, as simply controlling breathing without addressing these root causes will not lead to lasting change.

2. Choose Your Stress Response

Recognize that while physiological stress responses are automatic, you have a choice in how you behave and recover from that stress, allowing for adaptive responses.

3. Practice Cognitive Reframing

Look inwards at your triggers and identify internal insecurities or inadequacies being activated by external stimuli, rather than blaming external factors.

4. Invest in the Process

Invest fully in the process of daily activities and personal development, rather than being solely focused on future goals, to find unlimited possibility and presence.

5. Find Joy in Daily Activities

Cultivate joy and presence in mundane daily activities like washing dishes or doing laundry by reframing your perspective and investing in the process.

6. Say “No” for Freedom

Practice saying “no” to things you genuinely don’t want to do, even exciting opportunities, as this creates freedom and allows you to focus on what truly aligns with your desires.

7. Cultivate Breath Awareness

Become aware of your breathing patterns to regulate your stress response and overall health, as breath is the remote control to the nervous system.

8. Use Breathwork for Trauma

Use breathwork to change your nervous system state, enabling you to confront deep-seated pain or trauma that keeps you in a wired state.

9. Establish Clear Boundaries

Establish clear boundaries between work and personal life (e.g., stopping work emails at a set time) to signal to your nervous system that it’s time to switch off and relax.

10. Daily Nasal Breathing Walk

Engage in a daily 45-minute (or longer) walk, breathing exclusively through your nose and without screens, to build a metabolic foundation, improve stress response, and foster self-awareness.

11. Simple Calming Breathwork

Practice simple calming breathwork by inhaling and exhaling slowly through your nose, making the exhale slightly longer than the inhale, to comfortably bring down your nervous system.

12. Mindful Breathing Practice

Engage in a mindful breathing practice by closing your eyes and sequentially focusing on your belly movement (30s), chest movement (30s), and the air moving through your nostrils, allowing breathing to happen naturally without control.

13. Morning Breathwork Routine

Incorporate a 5-minute calming, grounding breathwork practice into your morning routine to intentionally start your day, regulate your nervous system, and improve metabolic function.

14. Mid-Day Breathwork Breaks

Take short (3-5 minute) breathwork breaks immediately after calls or meetings to regulate your nervous system and prevent accumulating stress throughout the day.

15. Downregulate After Arousal

After high-arousal activities (e.g., performing, intense work), find a quiet space to take 5-10 minutes for breathwork to downregulate your nervous system instead of resorting to unhealthy coping mechanisms.

16. Adopt Adult Bedtime Routine

Adopt a bedtime routine similar to children’s (dimming lights, relaxing activities) to signal to your nervous system that it’s time to wind down and prepare for sleep.

17. Prioritize Outdoor Movement

Prioritize outdoor movement and exposure to morning light, as these practices are critical for aligning with evolutionary biology and improving overall well-being.

18. Use Red Light at Night

Use red light in the evenings and at night (e.g., red filters on screens, red lights in home) to reduce stimulating blue light exposure, which positively impacts the metabolic system and sleep.

19. Engage in Hobbies

Engage in hobbies like creative cooking or outdoor activities to intentionally shift your nervous system state from work mode to a more playful and creative state.

20. Develop All Breathing Gears

Develop proficiency across all five breathing gears by incorporating moderate to high-intensity mouth breathing (Gear 4) during cardio intervals and power mouth breathing (Gear 5) during strength training. This ensures balanced respiratory system development and optimal oxygen utilization.

21. Match Breathing to Intensity

Match your breathing patterns to the appropriate level of movement and intensity, allowing your system to adapt and efficiently utilize oxygen, rather than artificially limiting it.

22. Include Strength Training

Include strength training at least twice a week to promote mitochondrial development, which is crucial for efficient oxygen utilization and overall metabolic health.

23. Vary Your Training

Incorporate variety into your training regimen, as diverse stimuli are more effective for adaptation and growth than repetitive routines.

24. Daily Walk for Self-Assessment

Use your daily walk as a self-assessment tool to gauge your body’s state and nervous system health, informing decisions about subsequent training intensity or rest.

25. Reframe ‘Have To’ to ‘Get To’

Reframe your language from “I have to” to “I get to” for daily tasks and situations, fostering a more positive and appreciative mindset.

26. Short-Lived Emotional Responses

Aim for emotions to be short-lived responses without carrying baggage from past experiences, allowing you to live in total joy.

27. Slow Down Excitement

Intentionally slow down and examine things that bring excitement to ensure they align with your true desires, preventing engagement in activities you didn’t actually want.

28. Core Values as Anchor

Establish and anchor yourself to core values like authenticity, as they provide a stable foundation for navigating interactions and decisions.

29. Avoid Chronic Stress

Actively let go of stress responses to avoid chronic stress, which prevents the parasympathetic nervous system from activating and leads to various health issues.

30. Performance for Growth

View performance as a path to personal growth, focusing on unlocking mental constructs to identify and overcome limitations.

31. Prioritize Playful Activities

Prioritize playful and nourishing activities by setting hard boundaries, recognizing their importance for well-being and presence, rather than relegating them to occasional leisure.

32. Physical Activity for Groundedness

Engage in regular physical activity to foster groundedness and presence, as movement is a fundamental component of well-being across various philosophies.

33. Breathing for Mitochondria

Actively work on your breath as a powerful “hack” to enhance mitochondrial function, which is central to energy production and overall health.

34. Understand Breathing Gears

Understand and apply the five-gear breathing system to match your breathing patterns to activity levels (Gear 1-5) for optimal performance.

35. Nasal Breathing for Fat Loss

Prioritize nasal breathing during low-to-moderate intensity activities to enhance fat burning, as nasal breathing promotes aerobic metabolism, which efficiently utilizes fatty acids.

36. Ability to Nap Indicator

Assess the health of your nervous system by your ability to take a nap after a stress response, as a healthy system can switch off and recover.

37. Life’s Narrative Determines Quality

Recognize that the quality of your life is determined by the narrative you choose to place on your experiences, not the experiences themselves.

38. Find Purpose in Everything

Shift your focus from finding a singular life purpose to actively finding purpose and mindfulness in every activity you undertake.

39. Behavioral Change is Key

Focus on changing behavioral patterns, as simply wanting to feel differently without altering behavior (like breathing patterns) is often ineffective.
