The Limitations of Traditional “Sick Care”
Good Energy critically examines the shortcomings of the prevailing “sick care” model, arguing it often delivers marginal improvements in long-term health. The authors contend that the current system is largely reactive, focusing on managing symptoms with pharmaceuticals and interventions after disease has already developed. This approach neglects the crucial role of preventative measures and addressing underlying metabolic imbalances.
Dr. Casey Means highlights that this system frequently fails to address the root causes of illness, leading to a cycle of ongoing treatment rather than genuine healing. The book proposes that prioritizing metabolic health—through diet, lifestyle, and continuous glucose monitoring—offers a more effective path towards sustained well-being, moving beyond simply treating illness to fostering true health.
Focus on Preventative Metabolic Care
Good Energy champions a paradigm shift towards preventative metabolic care, advocating for proactive strategies to optimize health before disease manifests. The authors emphasize that metabolic health—how efficiently the body converts food into energy—is foundational to overall well-being and longevity. This involves understanding and addressing factors like blood sugar control, insulin sensitivity, and inflammation.
The book details how continuous glucose monitoring (CGM), popularized by Levels (co-founded by Dr; Means), can provide valuable insights into individual metabolic responses to food and lifestyle choices. By focusing on optimizing metabolic function, individuals can unlock increased energy levels, improved cognitive function, and a reduced risk of chronic diseases, ultimately leading to a more vibrant and fulfilling life.

Understanding Metabolic Dysfunction
Good Energy meticulously explains how metabolic dysfunction arises from a complex interplay of factors, including dietary choices, lifestyle habits, and chronic stress. The authors highlight that a significant portion of the population experiences some degree of metabolic impairment, often without realizing it. This dysfunction manifests as imbalances in blood sugar, insulin resistance, and chronic inflammation—hallmarks of conditions like type 2 diabetes, heart disease, and obesity.

The book details how the modern food environment, characterized by processed foods and excessive sugar intake, contributes significantly to metabolic decline. Furthermore, it explores the impact of sedentary lifestyles and inadequate sleep on metabolic health, emphasizing the importance of holistic interventions to restore optimal function and prevent chronic disease.
The Role of Glucose Monitoring (Levels)

Good Energy strongly advocates for continuous glucose monitoring (CGM), particularly through the use of devices like Levels, as a powerful tool for understanding individual metabolic responses. Dr. Casey Means, as a co-founder of Levels, brings firsthand experience to this discussion, explaining how real-time glucose data empowers individuals to make informed dietary and lifestyle choices.

Good Energy emphasizes that CGM isn’t just for those with diabetes; it’s a valuable resource for anyone seeking to optimize their well-being;
Dietary Recommendations in Good Energy
Good Energy doesn’t prescribe a rigid diet, but instead champions a focus on food quality and metabolic impact. The authors advocate for prioritizing whole, unprocessed foods, emphasizing nutrient density over calorie counting. A cornerstone of their recommendations is minimizing refined carbohydrates and sugars, which contribute to significant glucose spikes and metabolic dysfunction.

The book encourages incorporating healthy fats and proteins into each meal to promote satiety and stabilize blood sugar. Good Energy also highlights the benefits of strategic carbohydrate timing, suggesting that consuming carbohydrates around periods of activity can improve metabolic flexibility. Ultimately, the dietary approach is personalized, guided by individual glucose responses revealed through continuous glucose monitoring.
Lifestyle Factors for Improved Metabolism
Good Energy emphasizes that metabolic health isn’t solely dictated by diet; lifestyle plays a crucial role. The authors strongly advocate for regular physical activity, not necessarily intense workouts, but consistent movement integrated into daily life. This includes incorporating activities like walking, strength training, and prioritizing non-exercise activity thermogenesis (NEAT).

Beyond exercise, Good Energy underscores the profound impact of sleep optimization on metabolic function. Sufficient, high-quality sleep is presented as essential for hormonal balance, glucose regulation, and overall metabolic resilience. Stress management techniques are also highlighted, as chronic stress can negatively impact metabolic processes. These lifestyle adjustments, combined with dietary changes, form the foundation of the book’s holistic approach.
Exercise and Physical Activity
Good Energy doesn’t prescribe grueling workout regimens, but champions consistent physical activity as a cornerstone of metabolic health. The book stresses that movement doesn’t need to be intense to be beneficial; incorporating walking, taking the stairs, and engaging in activities you enjoy are highly encouraged.
Furthermore, the authors advocate for strength training to build muscle mass, which significantly improves glucose disposal and metabolic rate. Prioritizing Non-Exercise Activity Thermogenesis (NEAT) – the energy expended for everything we do that isn’t sleeping, eating, or sports-like exercise – is also crucial. Good Energy emphasizes that finding sustainable, enjoyable forms of movement is key to long-term metabolic improvement.
Sleep Optimization
Good Energy underscores sleep as a non-negotiable pillar of metabolic health, often underestimated in conventional wellness approaches. The book details how insufficient or poor-quality sleep profoundly disrupts hormonal balance, particularly impacting cortisol and insulin levels, leading to metabolic dysfunction.
