How To Transform Your Metabolic Health & The Surprising Benefits of Walking with Alan Couzens #617

Jan 28, 2026 2h 1m 23 insights
When it comes to improving our health and fitness, most of us have absorbed the same message: work harder, push more, sweat more – basically, that no pain means no gain. But what if that story is not only wrong, what if it is actually holding you back? This week, I sit down with elite endurance coach Alan Couzens to completely reframe how we think about movement, fitness, and fat loss. Alan is both an exercise physiologist and a performance coach. He has spent the past three decades working with a wide range of endurance athletes at all ends of the performance spectrum, from ‘off the couch’ fitness athletes to the very best athletes in all of endurance sport. He shares his incredible wisdom & insights on X and his Substack, ‘The Science of Maximal Athletic Development’ which I would highly recommend if you want to go deeper into the topics we discuss in this week’s episode. Over the past few years, Alan has helped me to understand the critical importance of low intensity movement for health, performance and longevity, and in our conversation, we discuss: Why the ability to burn fat at low intensities is one of the most important markers of true metabolic health Why so many people feel they need to eat every two to three hours How very easy movement  can transform your health, your energy, your mood, and even your performance, often more than the hard workouts you think you “should” be doing The need to balance out the stresses of modern life with activities like walking and yoga The importance of building a big aerobic “engine” How best to think about intensity, strength training, VO₂ max, and muscle mass Why it is never too late to start increasing how much you move and experiencing the incredible benefits Alan is someone who I have a huge amount of respect for. Not only is he extremely knowledgeable and up to date with the latest science, he is also someone who has a huge amount of real-world experience helping people to improve their athletic performance and their health. My hope is that this episode serves as a powerful reminder that the human body simply does not work as well as it could, without adequate amounts of movement and that it inspires you to bring more easy movement into your life, in a way that supports your health for many decades to come   Support the podcast and enjoy Ad-Free episodes.

Actionable Insights

1. Nutritional Discipline is Muscle Strength

Understand that struggles with diet and weight are often due to muscles not being trained to burn fat, rather than a lack of willpower. This shift in perspective helps address the root metabolic issue.

2. Train for Fat-Burning Metabolism

Teach your body to efficiently generate energy from fat for low-intensity activities and daily living, reducing reliance on carbohydrates and stabilizing blood sugar. This is crucial for both health and athletic performance.

3. Embrace Easy, Low-Intensity Movement

Make very easy movement (Zone 0 and Zone 1, like walking and yoga) a priority in your daily life, as it profoundly impacts health, energy, mood, longevity, and even athletic performance more than high-intensity workouts.

4. Balance Stress with Easy Movement

Use low-intensity activities like walking and yoga to counteract the stresses of modern life, helping to switch your nervous system from “fight or flight” to “rest and digest” for better recovery and metabolic health.

5. Boost Daily Low-Intensity Volume

Consistently increase the overall volume of very low-intensity movement (Zone 0/1) throughout your day, as this sustained activity leads to significant improvements in health and performance.

6. All Movement Counts as Training

Shift your mindset to view all physical activity, including low-intensity movements like walking to the mailbox, as valuable “movement zones” that contribute to your overall health and fitness.

7. Build Heart Health with Low Effort

Engage in low-intensity movement to stimulate cardiac remodeling and increase heart size, which improves oxygen delivery and overall cardiovascular health over time.

8. Time-Crunched: Walk and Yoga

If you have limited time, prioritize daily easy walks in nature and short yoga sessions (even 15 minutes) to effectively de-stress and maintain foundational health.

9. Daily Stress Reset Practice

Integrate stress management techniques like yoga and taking five deep breaths every hour to create mental resets throughout the day, reducing fight-or-flight activation and positively impacting metabolism.

10. Easy Exercise for Fat Loss

If your goal is fat loss, focus exclusively on very easy, low-intensity exercise, such as gentle walks in nature, to train your muscles to burn stored fat more effectively.

11. Eat Real, Lower Carb Foods

Base your diet on real, whole foods and maintain a relatively low carbohydrate intake to support stable metabolism and enhance your body’s ability to burn fat.

12. Exercise “Crazy Easy” for Metabolism

Overcome the mental hurdle of “no pain, no gain” by consciously reducing your exercise intensity to “crazy easy” levels (e.g., an ambling walk) to effectively stimulate metabolic changes and fat burning.

13. Match Carbs to Movement

Adjust your carbohydrate intake to match your activity level, consuming fewer carbs on sedentary days and more (from whole foods) on active days, as your body preferentially burns available carbohydrates.

14. Fasted Morning Low-Intensity Movement

Engage in low-intensity movement, such as a morning walk, before eating breakfast to encourage your body to tap into and burn stored fat more efficiently.

15. Incorporate Aerobic Strength Training

After building an aerobic foundation, add basic, circuit-style strength training with relatively low loads and whole-body movements to maintain muscle mass and promote aerobic muscle development.

16. Prioritize Aerobic Muscle Quality

Focus on developing muscle mass that is rich in mitochondria and capillaries, supporting aerobic function and a higher VO2 max, rather than solely pursuing muscle bulk.

17. Increase Training to Maintain VO2 Max

To counteract the natural decline of VO2 max with age, commit to increasing your overall training volume, especially low-intensity movement, to maintain a high level of fitness into later decades.

18. Commit to Long-Term Consistency

Understand that lasting fitness adaptations come from consistent movement over years, not short bursts of intense training followed by inactivity, so prioritize sustainable habits.

19. Heed Body’s Signals, Prevent Injury

Develop the ability to listen to your body and address minor discomforts or “niggles” promptly to prevent them from escalating into injuries, ensuring uninterrupted training and long-term participation.

20. Choose Health-Conscious Lifestyle

Consciously select jobs and lifestyles that provide autonomy and time for health-promoting activities, avoiding cultures that demand excessive hours and compromise well-being.

21. Start Fitness Journey Anytime

Recognize that it is never too late to begin a fitness journey, as significant improvements in health and performance are achievable even when starting in your 40s, 50s, or beyond.

22. Utilize CGM for Metabolic Awareness

Consider using a continuous glucose monitor (CGM) to gain insights into how various factors like movement, stress, and sleep uniquely impact your blood sugar, helping you understand your metabolic state.

23. Limit High-Intensity Overload

Be cautious of overdoing high-intensity training, especially if it creates a significant imbalance between muscle capacity and heart function, as prolonged high heart rates can negatively impact heart health.
