Interesting review (that first graph in particular is definitely non-obvious to me), but under the diet section I think it understates the current body of research regarding low-carb/keto diets - some studies have begun to show energy expenditure[1] and insulin[2] benefits that uniquely exist with low-carb. I think we'll find out soon enough that a lower-carb approach, given the current American diet, does definitively perform better than other dieting approaches on average.
