Short Term Elevation in Dietary Protein Intake Does Not Worsen Insulin Resistance or Lipids in Older Adults with Metabolic Syndrome: a Randomized-Controlled Trial

The purpose of the study was to determine the influence of a short-term elevation in dietary protein on hepatic and peripheral insulin sensitivity in twelve older subjects (51–70 yrs) with metabolic syndrome.
