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.
