Are you eating enough fat? Yes, fat. Despite what generations of health science has beaten into us over the last fifty years or so, humans thrive on high-fat, low-carb diets. Millions of people around the world have discovered that a ketogenic lifestyle is the key to weight loss, disease prevention and intervention, and a more vibrant life, along with a slimmer waistline, elimination of cravings, and endless energy. Gone are the days when counting calories--or points!--was seen as the path to better health. Craig and Maria Emmerich have teamed up to write a book that digs deep into the science of ketogenic dieting, explaining how it can cure or control dozens of diseases and how it is fueling a new breed of athlete. All this is done in an easy-to-understand way that makes the complicated science much more approachable. Keto is the definitive guide to the ketogenic lifestyle. Inside, you'll learn How you can beat cancer, obesity, metabolic syndrome, coronary artery disease, high cholesterol, Alzheimer's disease, dementia, ADHD, anxiety, and depression into submission by making some simple yet impactful changes to your diet. How cholesterol and diabetes medications could very well be making you sicker rather than healthier. How generations of bad advice--advice designed to sell sugar, not health--has killed millions of people who blindly trusted the medical establishment and, worse still, the government to tell them the truth. How the overconsumption of carbohydrates is bad for your health and could be at the root of what ails you. How changing your inputs--the foods you eat--can change your outputs, meaning your quality of life. How our bodies really work, including detailed explanations of oxidative priority, fat flux, and lipolysis. This science is explained in such a way that everyone can understand how our bodies really process what we put into them. How inflammation is at the root of many diseases and how modern diets that are full of sugar, carbs, and omega-6 oils are sending us to early graves. How hormones control our moods, sex drive, blood sugar levels, muscle tone, fat-burning ability, metabolism, immune system, and much more--and how adopting a ketogenic lifestyle will change your waistline and your life!
