Gary Taube: “Good Calories, Bad Calories”

I highly recommend that you read Gary Taube’s book  Good Calories Bad Calories.

I find it amazing what he has accomplished regarding the scientific information about the diseases of civilization.
His conclusions:
  1. Dietary fat, whether saturated or not, is not a cause of obesity, heart disease, or any other chronic disease of civilization.
  2. The problem is the carbohydrates in the diet, their effect on insulin secretion, and thus the hormonal regulation of homeostasis, the entire harmonic ensemble of the human body.  The more easily digestible and refined the carbohydrates, the greater the effect on our health, weight, and well-being.
  3. Sugars-sucrose and high-fructose corn syrup specifically are particularly harmful, probably because the combination of fructose and glucose simultaneously elevates insulin levels while overloading the liver with carbohydrates.
  4. Through their direct effect on insulin and blood sugar, refined carbohydrates, starches, and sugars are the dietary cause of coronary heart disease and diabetes.  They are the most likely dietary causes of cancer, Alzheimer’s disease, and the other chronic diseases of civilization.
  5. Obesity is a disorder of excess fat accumulation, not overeating, and sedentary behavior.
  6. Consuming excess calories does not cause us to grow fatter, any more then it causes a child to grow taller.  Expending more energy than we consume does not lead to long-term weight loss; it leads to hunger.
  7. Fattening and obesity is caused by an imbalance, disequilibrium in the hormonal regulation of adipose tissue and fat metabolism.  Fat synthesis and storage exceed the mobilization of fat from the adipose tissue and its subsequent oxidation.  We become leaner when the hormonal regulation of the fat tissue reverses this balance.
  8. Insulin is the primary regulator of fat storage.  When insulin levels are elevated-either chronically or after a meal-we accumulate fat in our fat tissue.  When insulin levels fall, we release fat from our fat tissue and use it for fuel.
  9. By stimulating insulin secretion, carbohydrates make us fat, and ultimately cause obesity.  The fewer carbohydrates we consume, the leaner we will be.
  10. By driving fat accumulation, carbohydrates also increase hunger and decrease the amount of energy we expend in metabolism and physical activity.
