The Truth About Fitness and Keeping Your Brain Healthy with Dr Tommy Wood #167

Mar 24, 2021 1h 44m 24 insights
This week's guest is someone who I really respect - Dr. Tommy Wood has a biochemistry degree from the University of Cambridge, a medical degree from the University of Oxford and a PhD in physiology and neuroscience from the University of Oslo. He's currently a research assistant professor at the University of Washington, and he conducts research focusing on ways to increase resilience and treat injury in the developing brain. What I love about Tommy is that not only is his knowledge and education second to none, he's also got an incredible range of experience across a variety of different disciplines, which gives him a really broad perspective and an ability to see the big picture. Alongside his career in medicine and research, Tommy has invested a lot of time in developing easily accessible methods with which to track human health, performance and longevity. He’s published multiple scientific papers and lectured all over the world about the root causes of multiple sclerosis and insulin resistance. Tommy's goal, much like my own is to cut through the mixed health messages that we’re given in the media, by healthcare professionals, and even from scientific studies. His objective is to shine a light on the best way for people to approach these conflicting issues, and to help find ways to practically implement them in our daily lives. In this conversation, we cover a variety of fascinating different topics. We start off talking about fitness and endurance sports and how being fit might not be as healthy as you think. Tommy shares his own health journey through low self-esteem and orthorexia and we discuss how the language we use when talking about health is so important. We also cover the value of failure and how vital it is to keep challenging our brains as adults. Tommy explains the latest thinking on the various factors that can influence our brain health, from sleep and stress to movement and food. Finally, we touch on the crucial role that emotional health and human connection plays in brain health and the powerful idea that your brain needs a reason to be alive. I think one of the most empowering things to come out of this conversation is that the changes you need to make to improve your health and well-being are much smaller than you'd think. I hope you find this conversation inspiring.

Actionable Insights

1. Cultivate Self-Worth & Acceptance

Address self-worth as a root cause for health issues, as letting go of self-loathing and insecurity can provide more freedom in personal life and health, reducing the need to compensate with other behaviors.

2. Cultivate Social Connection & Purpose

Actively seek social connection and a sense of purpose within a group, as this provides critical input for the brain to keep working, telling your body it’s worth being alive and contributing.

3. Prioritize Subjective Well-being

Regularly ask yourself ‘How do I feel?’ as subjective quality of life and health are strong predictors of long-term health, guiding you to make changes based on your body’s response.

4. Adopt a Holistic Health Perspective

Avoid hyper-focusing on one area of health, as many environmental factors contribute to overall well-being; instead, consider all inputs like nutrition, sleep, movement, stress, and social connection together.

5. Focus on ‘Big Rocks’ of Health

Prioritize the foundational aspects of health: sleep, circadian rhythm (light/dark exposure), movement, stress mitigation, and social connection, as these are the biggest levers to improve long-term health.

6. Recognize Small Changes Have Impact

Understand that improving health does not require immense effort; small changes, like a brisk walk three times a week, can lead to significant positive knock-on effects on your brain and body.

7. Embrace Learning New Difficult Skills

Continuously engage in difficult new learning experiences to keep your brain healthy, as it needs ongoing stimulus to be told it’s needed, even if it means being bad at something initially.

8. Seek New Challenges After Mastery

Once a skill becomes easy and habitual, move on to a new challenge to maintain cognitive stimulus, as the brain requires ongoing difficulty to stay complex and healthy.

9. Overcome Fear of Failure in Learning

Challenge the societal tendency to avoid failing or ‘sucking’ at new things, as actively trying new and difficult activities is crucial for brain health and growth.

10. Prioritize Recovery for Strength

Understand that strength is gained through recovery, not just training; continuously pushing yourself without adequate rest leads to long-term detriment.

11. Balance Stress and Recovery

Manage your total stress load from all life spheres (exercise, sleep, diet, psychological) and ensure sufficient time for recovery, as continuous stress without adaptation leads to long-term detriment.

12. Value Physical Strength for Longevity

Prioritize developing and maintaining physical strength, as it is crucial for preventing falls and enabling daily activities well into old age, contributing to overall long-term health.

13. Aim for Daily Moderate Activity

Engage in 30 to 45 minutes of moderate to vigorous activity daily, such as a brisk walk, to achieve the vast majority of long-term health benefits from exercise.

14. Incorporate Play and Nature Interaction

Reintroduce play and interaction with the environment, other people, animals, and nature into your routine, as modern society often pulls us away from these natural stimuli essential for health.

15. Aim for 7-8 Hours Quality Sleep

Strive to spend seven to eight hours in bed, getting most of that time asleep, as both sleep quantity and quality are important for long-term brain health and overall well-being.

16. Prioritize Sleep for Empathy & Interactions

Recognize that sleep deprivation negatively impacts your ability to recognize positive emotions and empathize with others, making social interactions more likely to be negative.

17. Stabilize Blood Sugar Levels

Minimize large swings in blood sugar by avoiding foods that cause significant spikes, as this can have a negative effect on cognition over time, and improving control can enhance cognitive function.

18. Reduce Vegetable Oils & Processed Foods

Minimize the intake of vegetable oils, fried foods, and processed foods, as the linoleic acid in these can out-compete DHA for brain uptake and oxidized fats can negatively affect brain health.

19. Ensure Adequate DHA Intake

Consume sufficient DHA, a long-chain omega-3 fatty acid found in seafood like small fish (sardines, shellfish) or algal/krill supplements, as it is incredibly important for brain health.

20. Cook Whole Foods at Home

Prioritize cooking whole foods at home as much as possible, as this naturally reduces intake of processed foods and vegetable oils, providing multiple health benefits.

21. Include Choline-Rich Foods

Incorporate choline-rich foods like eggs, liver, and organ meats into your diet, as choline is very important for brain health.

22. Enjoy Occasional Treats Without Guilt

If you choose to have occasional treats like chips, enjoy them without guilt, as the stress and negative physiological effects of worrying about the food can be more detrimental than the food itself.

23. Avoid Negative Self-Talk About Health

Be mindful of the language you use about your health and genetics, as negative self-talk or being told negative information about your physiology can have a detrimental effect on your performance and well-being.

24. Don’t Stress Over Occasional Bad Sleep

Do not worry about a single night of bad sleep, as it typically has no meaningful negative long-term effect on your health; stress about it is likely more harmful.
