Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The 'ominous octad' of insulin resistance involves eight distinct problems within the muscle, suggesting a single drug is unlikely to correct all issues.

◐Partially SupportedIn obese individuals, there is a marked increase in fluorodeoxyglucose uptake in the brain's hedonic areas, which correlates inversely with muscle insulin resistance.

◐Partially SupportedDiabetes is a heterogeneous disease with defects in muscle, liver, fat cells, beta cells, or the brain capable of causing diabetic phenotypes.

◐Partially SupportedTreating type 2 diabetes requires drugs targeting the beta cell, insulin sensitizers, and drugs to reverse lipotoxicity.

◐Partially SupportedThe primary defect in glucose metabolism in type 2 diabetes involves impaired tyrosine phosphorylation of IRS1, leading to an inability to activate PI3K.

◐Partially SupportedIn type 2 diabetes, a primary defect in hexokinase phosphorylating glucose can back up the entire system even if IRS1 and GLUT4 transporters function.

◐Partially SupportedChildren of parents with type 2 diabetes, even if lean, exhibit insulin resistance and defects in the insulin signaling pathway, specifically at IRS1.

◐Partially SupportedFat accumulation in the liver, muscle, and kidneys are consequences of lipotoxicity from overeating.

◐Partially SupportedAlström syndrome involves a defect in the glucose transporter in white adipose tissue, leading to diabetes, weight gain, and NASH.

◐Partially SupportedProcessed foods, calorie-dense foods, and lack of exercise have altered brain neurocircuitry, contributing to the epidemic of obesity and related health issues.

◐Partially SupportedThe increase in childhood type 2 diabetes was evident in the late 1980s, predating the widespread use of video games and social media.

◐Partially SupportedKnocking out the gene responsible for Alström syndrome in animal models reproduces diabetes.

◐Partially SupportedThe primary defect in type 2 diabetes is debated to be glucose transport or hexokinase/phosphoglucose activity.
