Tl; dr: Author contrasts two explanations of the obesity and diabetes crises: A) that the root of the issue is caloric intake stemming from low-self-control or B) that the root of the issue is high blood-sugar and its subsequent effects. Author explores the long history of this debate and presents points for both sides. Author admits the thermodynamic validity of caloric math but cites that at a cellular glucose levels cause insulin levels to rise that cause the cell to take on fat. Author cites other research, such as increased appetite among obese animals, suggesting a systemic effect. Author cites ketogenic diets as evidence (which restrict sugars but not total calories). Author contrasts the moral interpretation of each theory. Proposes the caloric consumption model places blame on the individual, whereas the glucose explanation places blame on the FDA.
