Fix your metabolism to feel better today and prevent disease tomorrow. A bold new vision for optimizing our health now and for the future.

What if depression, anxiety, infertility, insomnia, heart disease, type 2 diabetes, Alzheimer’s, dementia, cancer and many other health conditions actually have the same root cause?

Our ability to prevent and reverse these conditions – and feel incredible today – is under our control and simpler than we think. The key is our metabolic function – the most important and least understood factor in our overall health. As Dr Casey Means explains in this groundbreaking book, nearly every health problem we face can be explained by how well the cells in our body create and use energy. To live free from frustrating symptoms and life-threatening disease, we need our cells to be optimally powered so that they can create 'good energy', the essential fuel that impacts every aspect of our physical and mental wellbeing.

If you are battling signals of 'bad energy' inside your body, it is often a warning sign that more life-threatening illness may emerge later in life. Weaving together cutting-edge research and personal stories, Good Energy offers an essential four-week plan and explains:

• The five biomarkers that determine your risk for a deadly disease

• The crucial links between sleep, circadian rhythm, and metabolism
• A framework for exercise focused on building simple movement into every day
• How cold and heat exposure helps build our body’s resilience
• Steps to navigate the medical system to get what you need for optimal health
