I think the article's main point is it's not specifically weight we should be worried about. > obesity is associated with higher rates of mortality, disease, heart conditions A diet high in fat/cholesterol/calories can indeed increase your risk of heart conditions and diabetes (and thus mortality). But that's the fat, not the obesity itself. Cholesterol levels can be measured independently - but some doctors just take the shortcut of saying obesity = unhealthy. This article is asking whether or not that's a mistake.
