The conventional glucocentric perspective of type 2 diabetes views hyperglycemia as a primary disease caused by an etiologically uncertain combination of obesity-associated insulin resistance and beta cell loss (a disease of glucose metabolism to be treated with antihyperglycemic agents, including high-dose insulin, if necessary). By contrast, the novel lipocentric view depicts the hyperglycemia of type 2 diabetes, and the underlying insulin resistance and beta cell loss, as being secondary to the metabolic trauma caused by ectopic lipid deposition or lipotoxicity.¹ If this is in fact the case, hyperglycemia should be corrected by eliminating the lipid overload. The study by Dixon et al² provides support for this lipocentric hypothesis, by demonstrating that weight loss that follows gastric banding is accompanied by remission of diabetes in 73% of obese patients with type 2 diabetes. This finding supports 45 years of biochemical, physiological, and clinical research pointing to lipid . . . [Full Text of this Article]
