This article will explore the core concepts presented in *Good Energy* by Casey Means, examining its impact on understanding and improving metabolic health for overall well-being. We’ll delve into the book’s foundational principles, assess its strengths and potential limitations, and highlight practical applications for readers seeking to enhance their energy levels, improve their health markers, and live a more fulfilling life. Whether you’re a health enthusiast, struggling with chronic fatigue, or simply curious about optimizing your well-being, this deep dive into *Good Energy* offers valuable insights.
Metabolic Health as the Foundation of Well-being
*Good Energy* challenges the conventional, often fragmented approach to healthcare, arguing that metabolic health should be the cornerstone of overall well-being. Casey Means makes a compelling case that our metabolism, the intricate network of chemical processes that convert food into energy, directly influences every aspect of our health. Poor metabolic health, often stemming from modern dietary habits and lifestyles, can manifest in a myriad of ways, from persistent fatigue and mood swings to increased risk of chronic diseases such as type two diabetes, heart disease, and even Alzheimer’s disease.
The book emphasizes that energy, in its purest form, is a direct reflection of our metabolic function. When our metabolism is functioning optimally, we experience sustained energy levels throughout the day, improved cognitive function, better sleep, and a greater resilience to stress. Conversely, metabolic dysfunction can lead to energy crashes, brain fog, increased inflammation, and a compromised immune system. *Good Energy* provides a framework for understanding how to shift from a state of metabolic dysfunction to one of vibrant metabolic health, unlocking a cascade of positive effects throughout the body.
The Glucose Connection: Understanding Your Body’s Fuel
A central tenet of *Good Energy* is the importance of understanding glucose levels and their profound impact on metabolic function. The book meticulously explains how glucose, a simple sugar derived from the food we eat, serves as the primary fuel source for our cells. However, consistently elevated glucose levels, a hallmark of insulin resistance, can wreak havoc on our metabolic health.
Casey Means argues that relying solely on traditional blood sugar tests, such as the A1c, which provides an average glucose level over several months, often misses critical fluctuations and spikes that contribute to metabolic damage. *Good Energy* advocates for the use of continuous glucose monitoring (CGM) as a powerful tool for gaining real-time insights into how different foods, activities, and stressors affect our glucose levels. By tracking these fluctuations, individuals can learn to make informed choices that promote stable blood sugar and improve metabolic control. The book provides guidance on interpreting CGM data and using it to personalize dietary and lifestyle strategies.
Metabolic Flexibility: The Key to Adaptability
Metabolic flexibility, the ability of the body to efficiently switch between using glucose and fat for fuel, is another crucial concept explored in *Good Energy*. Individuals with good metabolic flexibility can easily adapt to changing energy demands, whether it’s burning glucose during intense exercise or tapping into fat stores during periods of fasting. Conversely, individuals with poor metabolic flexibility are often glucose-dependent, experiencing energy crashes when blood sugar drops and struggling to burn fat for fuel.
*Good Energy* outlines several strategies to improve metabolic flexibility, including adopting a nutrient-dense diet, engaging in regular exercise (both aerobic and resistance training), practicing intermittent fasting, and prioritizing sleep. The book emphasizes the importance of creating a metabolic environment that encourages the body to become more efficient at utilizing both glucose and fat, ultimately leading to sustained energy, improved body composition, and enhanced overall health.
Nutrition Strategies: Fueling Your Metabolism for Success
The dietary recommendations in *Good Energy* prioritize whole, unprocessed foods, emphasizing nutrient density and minimizing refined carbohydrates, added sugars, and unhealthy fats. Casey Means advocates for a personalized approach to nutrition, encouraging readers to experiment with different dietary strategies and find what works best for their individual needs and preferences, while closely monitoring their CGM data.
The book encourages prioritizing foods rich in fiber, healthy fats, and lean protein, such as vegetables, fruits, nuts, seeds, avocados, olive oil, fatty fish, and grass-fed meats. While not explicitly advocating for a specific dietary label (e.g., low-carb, ketogenic), *Good Energy* leans towards a lower-carbohydrate approach, particularly for individuals with insulin resistance or prediabetes. However, the book emphasizes that carbohydrate tolerance varies significantly from person to person, and the key is to find a carbohydrate intake that supports stable blood sugar and sustained energy. Mindful eating practices are also highlighted as a way to improve digestion and enhance the body’s ability to utilize nutrients.
Lifestyle Factors: Beyond Diet for a Vibrant Metabolism
*Good Energy* recognizes that metabolic health is not solely determined by diet; lifestyle factors play an equally crucial role. The book dedicates significant attention to the importance of exercise, sleep, stress management, and sunlight exposure. Regular physical activity, both aerobic and resistance training, helps improve insulin sensitivity, enhance metabolic flexibility, and promote overall cardiovascular health.
Prioritizing quality sleep is essential for regulating hormones, reducing inflammation, and supporting optimal metabolic function. *Good Energy* provides practical tips for improving sleep hygiene, such as establishing a regular sleep schedule, creating a relaxing bedtime routine, and optimizing the sleep environment. Managing stress, whether through mindfulness practices, yoga, or spending time in nature, is crucial for preventing chronic inflammation and supporting healthy cortisol levels. Finally, adequate sunlight exposure is vital for vitamin D production, which plays a critical role in immune function, bone health, and metabolic regulation.
Mitochondrial Health: Powering Your Cellular Engines
*Good Energy* also addresses the importance of mitochondrial health, highlighting the role of these tiny organelles in energy production. Mitochondria, often referred to as the “powerhouses” of our cells, are responsible for converting nutrients into usable energy. When mitochondria are healthy and functioning optimally, we experience increased energy levels, improved cognitive function, and a reduced risk of chronic diseases.
The book discusses strategies to support mitochondrial function through nutrition and lifestyle, including consuming a diet rich in antioxidants, avoiding processed foods and toxins, engaging in regular exercise, and ensuring adequate sleep. Specific nutrients like CoQten, L-carnitine, and alpha-lipoic acid are mentioned for their potential benefits in supporting mitochondrial function. The book emphasizes protecting mitochondria from damage and providing them with the necessary building blocks to thrive.
Strengths of Good Energy: An Evidence-Based and Actionable Guide
One of the key strengths of *Good Energy* is its evidence-based approach.

Potential Criticisms and Limitations: A Balanced Perspective
While *Good Energy* offers a wealth of valuable information, it’s important to acknowledge potential criticisms and limitations. The book’s emphasis on continuous glucose monitoring (CGM) may be a barrier for some individuals due to the cost and accessibility of these devices. While CGMs provide valuable insights, they are not essential for everyone, and many of the book’s recommendations can be implemented without them.
Some of the dietary recommendations may also be challenging or restrictive for certain individuals, particularly those with specific dietary needs or preferences. The book’s lean towards a lower-carbohydrate approach might not be suitable for everyone, and it’s important to personalize dietary strategies based on individual needs and responses. Finally, it’s crucial to remember that individual responses to dietary and lifestyle changes can vary significantly. What works for one person may not work for another, and personalized approaches are often necessary.
