" The medical research community came to recognize that insulin resistance and a condition now known as “metabolic syndrome” is a major, if not the major, risk factor for heart disease and diabetes. Before we get either heart disease or diabetes, we first manifest metabolic syndrome. The CDC now estimates that some seventy-five million adult Americans have metabolic syndrome. The very first symptom or diagnostic criterion that doctors are told to look for in diagnosing metabolic syndrome is an expanding waistline. This means that if you’re overweight or obese—as two-thirds of American adults are—there’s a good chance that you have metabolic syndrome; it also means that your blood pressure is likely to be elevated, and you’re glucose-intolerant and thus on the way to becoming diabetic. This is why you’re more likely to have a heart attack than a lean individual—although lean individuals can also have metabolic syndrome, and those who do are more likely to have heart disease and diabetes than lean individuals without it. Metabolic syndrome ties together a host of disorders that the medical community typically thought of as unrelated, or at least having separate and distinct causes—getting fatter (obesity), high blood pressure (hypertension), high triglycerides, low HDL cholesterol (dyslipidemia), heart disease (atherosclerosis), high blood sugar (diabetes), and inflammation (pick your disease)—as products of insulin resistance and high circulating insulin levels (hyperinsulinemia). It’s a kind of homeostatic disruption in which regulatory systems throughout the body are misbehaving with slow, chronic, pathological consequences everywhere. "
