“In other words, the science itself makes clear that hormones, enzymes, and growth factors regulate our fat tissue, just as they do everything else in the human body, and that we do not get fat because we overeat; we get fat because the carbohydrates in our diet make us fat. The science tells us that obesity is ultimately the result of a hormonal imbalance, not a caloric one—specifically, the stimulation of insulin secretion caused by eating easily digestible, carbohydrate-rich foods: refined carbohydrates, including flour and cereal grains, starchy vegetables such as potatoes, and sugars, like sucrose (table sugar) and high-fructose corn syrup. These carbohydrates literally make us fat, and by driving us to accumulate fat, they make us hungrier and they make us sedentary.This is the fundamental reality of why we fatten, and if we’re to get lean and stay lean we’ll have to understand and accept it, and, perhaps more important, our doctors are going to have to understand and acknowledge it, too.”

“The simple answer as to why we get fat is that carbohydrates make us so; protein and fat do not”

“The simplest way to look at all these associations, between obesity, heart disease, type 2 diabetes, metabolic syndrome, cancer, and Alzheimer's (not to mention the other the conditions that also associate with obesity and diabetes, such as gout, asthma, and fatty liver disease), is that what makes us fat - the quality and quantity of carbohydrates we consume - also makes us sick.”

“We don't get fat because we overeat; we overeat because we're getting fat”

“And just as agriculture has displaced species-dense communities with its monocrops, its diet has displaced the nutrient-dense foods that humans need, replacing them with mononutrients of sugar and starch. This displacement led immediately to a drop in human stature as agriculture spread - the evidence couldn’t be clearer. The reasons are just as clear. Meat contains protein, minerals, and fats, fats that we need to metabolize those proteins and minerals. In contrast, grains are basically carbohydrates: what protein they do contain is low quality - lacking essential amino acids - and comes wrapped in indigestible fiber. Grains are essentially sugar with enough opioids to make them addictive.”

“I have heard one doctor call high-protein, high-fat, low-carbohydrate diets “make-yourself-sick” diets, and I think that’s an appropriate moniker. You can also lose weight by undergoing chemotherapy or starting a heroin addiction, but I wouldn’t recommend those, either.”
