Please note: This is a companion version & not the original book. Sample Book Insights: #1 The problems many people face these days come on slowly. They develop over years, and you don't even notice they're happening until they're out of control. #2 The very foods we've been told to eat for years-carbohydrate-rich foods-don't give us the nutrients we need to feel full, nor do they keep us from feeling hungry. They just don't work. #3 The laws of thermodynamics, which state that a system is only ever open or closed, are not valid in the human body. An open system is the human body, and the number of calories in a given food is meaningless. What is important is what those calories are used for. #4 The notion of calories is flawed, so instead of relying on them, we should rely on the general rule that fat provides 9 calories per gram, and carbohydrates and protein each provide 4 calories per gram. Thus, 1 gram of fat provides more than double the calories of 1 gram of either carbohydrate or protein.
