Metabolic syndrome -- don't blame the belly fat

pocytokines, suggesting that these abnormalities develop later in the development of the metabolic syndrome."

The new findings promise to help untangle the early molecular events of a syndrome at the root of one of the world's most significant health issues. Knowing how insulin resistance alters energy storage before it leads to more serious problems can help those susceptible prevent the onset of the metabolic syndrome, Shulman said.

Another key observation was that skeletal muscle insulin resistance precedes the development of insulin resistance in liver cells, and that fat production in the liver is increased. These findings also have important implications for understanding the pathogenesis of nonalcoholic fatty liver disease, one of the most prevalent liver diseases in both adults and children Shulman said.

The good news, according to Shulman, is that insulin resistance in skeletal muscle can be countered through a simple intervention: exercise.
