<p>In this episode, Dr. Ronesh Sinha, a physician, author, and educator based in Silicon Valley, shares his many insights into metabolic illness that he has gleaned from his South Asian patient population. In this conversation we focus on hyperinsulinemia, insulin resistance, metabolic dysregulation, inflammation, blood pressure, obesity, etc. and ways to address them with nutrition, sleep, exercise, stress management, and more. We also take a deep dive into insulin resistant phenotypes, evolutionary theory and geographic determinants of insulin resistance which provides insight into the genetic architecture and pathophysiology of metabolic syndrome. Additionally, we discuss the surprisingly interrelated topic of stress, and how we might be inadvertently passing this on to our children, leading to mental and physical sickness down the road.</p> <p><span style="color: #201f1e;">We discuss:</span><span style="color: #333333;"><br /></span></p> <ul> <li><span style="color: #201f1e;">How a stubborn case of insulin resistance connected Peter with Ronesh [7:15];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Ronesh's clinical treatment focus of metabolic illnesses in South and East Asian patient populations [8:45];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">The distinction between visceral fat and subcutaneous fat stores [15:00];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Shortcomings of a body mass index (BMI) calculator for evaluating metabolic disease risk [17:15];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Cortisol and blood glucose variability [28:30];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Insulin's role in elevated blood glucose: A symptom of metabolic syndrome [33:25];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Mechanistic explanations of insulin resistance (there may be more than one) [35:15];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Theories on origins and evolutionary reasons for insulin resistance [40:00];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">The inverse relationship between the amount of brown adipose tissue and rates of insulin resistance, and the role of climate in patterns and prevalence of insulin resistance [49:50];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Vitamin D levels, hyperinsulinemia, and other effects [53:45];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">The evolutionary benefit of being able to turn fructose into fat (and the price we are now paying for it) [58:00];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">The VO2 max relationship to insulin resistance and familial metabolic health [59:30];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Using zone 2 fitness test to evaluate mitochondrial performance [1:01:15];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Exercise for long-term functional health [1:06:00];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Lifestyle changes to improve insulin resistance and other metabolic phenotypes [1:14:00];</span><span style="color: #333333;"><br /></span></li> <li><span style="color: #201f1e;">Is PCOS a manifestation of insulin resistance?

Actionable Insights
1. Focus on Insulin Resistance
Shift your health focus from low-fat, low-cholesterol, caloric models to addressing insulin resistance as the root cause of metabolic issues, especially if traditional approaches aren’t working.
2. Reduce Carbs, Increase Healthy Fats
To dramatically improve high triglycerides and HDL, significantly reduce carbohydrate intake and be liberal with healthy fat intake. This addresses the conversion of glucose into triglycerides.
3. Track Triglycerides Regularly
After making dietary changes, track your triglycerides every 2-3 weeks to monitor your body’s response and see the impact of your interventions.
4. Address Pre-Pre-Diabetes Early
If you have normal glucose but high triglycerides, fatty liver, or an elevated waist circumference, recognize this as ‘pre-pre-diabetes’ and intervene early to preserve beta cell function and prevent full-blown diabetes.
5. Measure Fasting Insulin
Check your fasting insulin levels to detect early hyperinsulinemia, even if your glucose levels appear normal, as this is an early sign of metabolic dysregulation.
6. Use Continuous Glucose Monitor
Wear a CGM for 3-6 months to gain insights into how different foods, exercise, sleep, and stress personally affect your glucose levels. Continue using it for behavioral modification and to gamify your health goals.
7. Implement Calming Nighttime Rituals
To improve fasting blood sugars, establish calming nighttime routines, get off electronic devices, and practice meditative techniques in the evenings, as cortisol significantly impacts liver glucose output.
8. Prioritize Sleep Duration
Aim for 8 hours of actual sleep per night, as consistent sleep duration can significantly improve metabolic health and overall well-being. Track your sleep to understand your true duration and efficiency.
Recognize that emotional distress and anger can rapidly elevate glucose levels and contribute to metabolic issues. Actively work on stress management to mitigate these physiological impacts.
10. Engage in Zone 2 Cardio
Dedicate 3-4 hours per week to Zone 2 cardio training (at an intensity where you can still hold a conversation) to improve mitochondrial efficiency and overall metabolic health.
11. Implement Comprehensive Exercise Plan
For long-term health and functionality, incorporate four components of exercise into your routine: stability, strength (hip hinge, pull, push), aerobic (Zone 2), and anaerobic (HIIT).
12. Prioritize Leg Strength
Focus on building leg strength through weightlifting, especially if you have thin limbs or insulin resistance, to create more glycogen parking space and improve metabolic function.
13. Balance Cardio and Strength
Ensure a delicate balance between aerobic training and strength training, as too much endurance work can lead to muscle mass loss, which can compromise metabolic health in certain populations.
14. Lower Uric Acid for Hypertension
Consider lowering uric acid levels (below 5 mg/dL) as a primary intervention for hypertension, potentially even before using antihypertensive medication, due to its profound effect on blood pressure.
15. Supplement Vitamin D for Deficiency
If your vitamin D levels are very low (e.g., single digits), supplement to bring them up to 30-40 ng/mL, which can improve C-reactive protein and hypertension.
16. Avoid Excessive Vitamin D
Do not aim for excessively high vitamin D levels (e.g., 80-90 ng/mL) through supplementation, especially if you are in a population with higher rates of coronary calcification.
17. Correct Sleep Apnea
Screen for and correct sleep apnea, as intermittent hypoxia during the night is a major inflammatory stimulus that can significantly worsen glucose numbers and insulin resistance.
18. Engage Family in Health Changes
Involve your entire family in health discussions and lifestyle changes, as family dynamics and habits (e.g., cooking, stress from relatives) can profoundly impact an individual’s ability to maintain health.
19. Recognize PCOS as Insulin Resistance
Understand that Polycystic Ovarian Syndrome (PCOS) is often an ‘insulin-resistant ovarian syndrome.’ Implementing lifestyle changes to lower insulin levels can frequently reverse its manifestations.
20. Address Stubborn Weight Loss
If you’re struggling with weight loss despite diet and exercise (often seen in females with high inflammation, sleep/stress dysregulation, or thyroid issues), prioritize 8 hours of sleep, daily exercise, and stress management, understanding that results may take longer.
21. Integrate Activity into Workday
For busy individuals, integrate physical activity and stress management into your workday, such as doing squats by 12 PM or using breathing techniques to lower your heart rate during meetings.
22. Use Heart Rate as Biofeedback
Monitor your heart rate during stressful situations or meetings as a form of biofeedback. Actively practice breathing techniques to lower your heart rate and observe the physiological impact.
23. View Mindfulness as Training
Approach mindfulness meditation as a training tool, similar to going to the gym, to develop the ability to observe thoughts without reacting, which can lead to greater emotional resilience and less misery.
24. Encourage Hobbies for Joy
Foster hobbies in yourself and your children for pure enjoyment and stress reduction, rather than for external validation or resume building, to cultivate lifelong sources of pleasure and coping mechanisms.
25. Model Emotional Expression
Model emotional expression for your children by openly sharing your own frustrations and challenges (e.g., using a ‘roses and thorns’ exercise). This encourages them to express their emotions and prevents rumination.
26. Empower Kids in Decisions
Involve your children in family decisions and seek their advice, fostering a sense of ownership and partnership rather than a top-down, authoritarian dynamic.
27. Delay Smartphone Introduction
Delay giving children smartphones for as long as possible, viewing them as a ‘drug or toxin’ due to their addictive nature, impact on sleep, social issues, and potential for family conflict.
28. Model Responsible Phone Use
As parents, model responsible phone use and actively introduce alternative activities (e.g., family walks, camping trips with no devices) to naturally reduce screen time and foster enjoyable, device-free experiences.
29. Avoid Overly Pushing Children
Be mindful of ‘pyramid parenting’ and avoid placing excessive academic or athletic pressure on children. This can lead to accelerated life, stress, insulin resistance, and inflammation later in life.
30. Prioritize Children’s Sleep
Make children’s bedtimes non-negotiable, even in high school, as adequate sleep is crucial for their health, organization, and ability to focus, countering societal trends of late-night activities.
31. Support Value-Aligned Content
If you find value in content that aligns with your goals (like health and longevity), consider supporting it directly through subscriptions or memberships to ensure its continued production and integrity, free from advertising influence.
