In this episode of the Huberman Lab podcast, Dr. Casey Means and host Andrew Huberman explore metabolic health and its central role in preventing chronic diseases. They delve into the concerning prevalence of metabolic dysfunction among American adults, emphasizing the impact of lifestyle factors like diet, exercise, and stress management on mitochondrial function and overall metabolism.
Means shares practical strategies for optimizing metabolic health through dietary choices, movement patterns, sleep hygiene, and environmental exposures like heat and cold. The discussion highlights the importance of monitoring key biomarkers and leveraging tools like continuous glucose monitoring, while also underscoring the benefits of mindfulness practices and reconnecting with natural cycles for reducing chronic stress and fostering metabolic balance.

According to Casey Means, metabolic dysfunction underlies most chronic diseases afflicting Americans today. Means cites studies indicating around 93% of American adults have suboptimal metabolism due to lifestyle factors like diet, sleep patterns, and activity levels.
Mitochondria produce cellular energy and are central to metabolic health. Casey Means describes a destructive "trifecta" of mitochondrial dysfunction, chronic inflammation, and oxidative stress that drives metabolic diseases like arthritis and type 2 diabetes. Environmental factors like chronic stress, sedentary lifestyles, and poor diet compromise mitochondrial capacity.
Means recommends whole, minimally processed foods rich in fiber, omega-3s, healthy protein, probiotics, and antioxidants to support satiety, microbiome health, and metabolic signaling. She also suggests restricting eating windows and reducing ultra-processed foods that disrupt these processes.
Regular walking and low-intensity activities promote glucose disposal, while resistance training, HIIT, and endurance exercise stimulate mitochondrial biogenesis and function, according to Means and Andrew Huberman.
Huberman emphasizes adequate, high-quality sleep to support metabolic processes and hormone regulation. Means suggests using cold and heat exposure to enhance mitochondrial function and adaptive stress responses.
Experts advocate monitoring glucose, triglycerides, HbA1c, and other biomarkers. Continuous glucose monitoring reveals personal glycemic responses, empowering optimization, says Means.
Means discusses reducing chronic stress through mental-emotional practices and nature exposure to positively impact mitochondrial function and metabolic health. Reconnecting with natural cycles can cultivate trust in the body's self-regulation.
1-Page Summary
Understanding metabolic function and addressing metabolic dysfunction are critical for countering chronic diseases that are prevalent in modern society.
Andrew Huberman and Casey Means discuss the core role of metabolism in health. Metabolic function is fundamental for regulating hormones, blood sugar, and much more. Means asserts that the current state of metabolism in the American population is dire, as metabolic dysfunction underlies nine of the ten leading causes of death in the United States. When cellular energy is insufficient, it results in widespread dysfunction, fostering a range of metabolic diseases. The obesity and overweight epidemic, which affects nearly 80% of Americans, stems from mitochondrial dysfunction provoked by our environment.
Means speaks to the impact of the modern environment on metabolic health, pointing out how our dietary choices, sleep patterns, activity levels, and other lifestyle factors contribute to widespread metabolic dysfunction. She refers to studies showing that a significant majority of American adults, according to specific biomarkers, are metabolically dysfunctional. The American College of Cardiology suggests 93% of American adults have suboptimal metabolism. Through our lifestyle choices, we are constantly influencing our metabolic function, indicating there is room for change and improvement.
Mitochondria, the energy-producing organelles in our cells, are at the heart of metabolic health. Means explains how they are responsible for converting the energy from food into a form that the body can use. The modern environment's rapid changes negatively impact mitochondrial function across various mechanisms.

Metabolic Health
Discussions by Kaya Henderson, Andrew Huberman, and Casey Means reveal the underlying dietary, exercise, and environmental factors that significantly impact metabolic health.
The conversation delves into the importance of food as the building blocks of the body and its profound influence on cellular and metabolic health.
Casey Means emphasizes that one of the core aspects of diet most people get wrong is the quality of the food they consume. She suggests a focus on whole, minimally processed foods rich in fiber, omega-3s, healthy proteins, probiotics, and antioxidants. This type of diet supports satiety, modulates the microbiome, and changes reward circuitry. Andrew Huberman notes the importance of consuming a range of high-quality nutrient-rich foods for their amino acids and other nutrients.
Casey Means discusses the benefits of restricting the eating window to daytime hours to support metabolic health. Studies have revealed that a smaller eating window is associated with lower glucose and insulin levels. Huberman shares his personal experience with time-restricted feeding, opting for an eight to ten-hour eating window for its favorable effects on metabolic health.
Means and Huberman elaborate on the detrimental effects of ultra-processed, nutrient-poor foods on satiety and metabolic signaling. Such foods confuse the body's natural signaling mechanisms, leading to overeating and cellular dysfunction. They emphasize that reducing the intake of these foods is crucial for maintaining proper metabolic health.
The importance of various forms of exercise and their respective influences on mitochondrial health, including walking, resistance training, high-intensity interval training (HIIT), and endurance training, are discussed.
Casey Means urges incorporating walking and low-intensity physical activities throughout the day, emphasizing that regular movement can have dramatic benefits on glucose disposal. Walking post-meal is particularly highlighted as a high-impact activity that significantly lowers glucose response.
Huberman and Means also touch upon high-intensity exercises such as resistance training, HIIT, and endurance exercise for ...
Lifestyle Factors Impacting Metabolic Health
Achieving optimal metabolic health involves understanding and tracking critical markers, as well as addressing mental well-being and our connection to nature. Experts in the field are avidly discussing innovative ways to monitor these markers and how lifestyle choices can make substantial differences in our metabolic function.
Experts emphasize the importance of monitoring standard metabolic markers like glucose, triglycerides, HbA1c, and more, which provide insights into metabolic health. Continuous glucose monitoring (CGM) systems reveal personal glycemic responses and trends, empowering individual optimization.
Huberman notes the benefits of CGMs, including understanding the downstream metabolic effects of meals, and expresses interest in monitoring a wider range of biomarkers. Casey Means highlights the release of new continuous monitoring devices that measure not just glucose but also biomarkers like ketones and lactate. These devices, she points out, empower users to make better health decisions. CGMs have also been shown to provide early detection of metabolic issues and help regulate blood sugar which is critical for maintaining insulin sensitivity and longevity.
Reducing stress and reconnecting with nature can significantly affect our metabolic health, suggesting that individuals need to manage psychological stress to maintain optimal metabolic function.
Continuous glucose monitoring data has revealed that stress can lead to increased blood sugar levels, and experts like Casey Means discuss the crucial role of reducing chronic stress and emotional imbalances on metabolic health. Mitochondria, the cellular powerhouse ...
