The concepts and recipes in this book will allow you to: 1. Double your body's peak fat burning rate so you can go farther, faster while getting leaner5.2. Cut the weight of the food in your backpack by half without cutting calories.Your ability to burn fat will improve because of the unique metabolic changes caused by a diet high in fat, moderate in protein and very low in carbohydrates. Such a diet is called ketogenic, because it results in the conversion of fats to a form usable by the brain called ketones6. The ketogenic diet is not new. Ketogenic foods such as pemmican have been used by American Indians for long distance travel, and use of nutritional ketosis for ultra-endurance performance is gaining popularity in steady-state events such as Ironman Triathlon and Ultrarunning7. Many excellent ketogenic recipe books already exist, but their ingredients or techniques are unsuitable for backpacking. You are reading the first book to adapt the ketogenic diet to the specific constraints of backpacking. The first section of this book describes the physiology of how the ketogenic diet works. When you understand the underlying mechanisms of human nutrition related to fat metabolism, especially the role of insulin, you can see how other diets that appear radically different from the ketogenic diet such as a the slow-carb diet, accomplish similar goals in different ways. This understanding will allow you to weigh the pros and cons of various dietary approaches and choose the most appropriate approach for your situation.
