    Abdominal fat, the spare tire that many of us carry, has long been implicated as a primary suspect in causing the metabolic syndrome, a cluster of conditions that includes the most dangerous heart attack risk factors: prediabetes, diabetes, high blood pressure, and changes in cholesterol. But researchers have found that insulin resistance in skeletal muscle leads to alterations in energy storage that set the stage for the metabolic syndrome.
