A new groundbreaking health book for everyone. Fix your metabolism to feel better today and prevent disease tomorrow. Humans are getting sicker, fatter, and more depressed, despite huge advances in medical ‘cures' and treatments. A system that relies on surgery and drugs rather than prevention and lifestyle changes, is entirely unsustainable. When Dr Casey Means was in medical school and residency, it became clear to her that doctors were trained to think of patients as 42 unrelated parts and commonly performed procedures and prescribed medications that potentially inhibited their ability to recover from their ailments long-term. This book is at the forefront of preventative and holistic medicine and lifestyle. Nearly every health issue we face – from the fatigue we feel today to the chronic diseases that will shorten our lives tomorrow – is tied to how our bodies create and process cellular energy. Almost all illnesses and diseases are caused by a dysregulation in how our cells process energy. The body is made of 37 billion interconnected cells, each fuelled by glucose, delivered predominantly (but not exclusively) by the foods we eat. We are all aware of the impact of this in the body of someone with diabetes, however dysregulation of cells affects us all (even if we don't know it yet) and is caused by our unhealthy modern lifestyles – mainly too much processed food and a sedentary lifestyle – causing our cells to release too much insulin and preventing them from working effectively. Other pressures such as chronic stress and a lack of sleep– and even microplastics and toxins in other products we're exposed to – damage our mitochondria (responsible for hormonal responses to stress), and can lead to cell death. And excess glucose in the bloodstream damages blood vessels, causes inflammation, and leads to further cell damage. Casey presents the data to prove this, and delivers on the solutions to overhaul our lifestyles and allow us to be our healthiest and happiest selves. Including a 28-day reset plan to reboot your metabolism and implement life-changing habits for good.
