Effects of Insulin Resistance and Obesity on Lipoproteins and Sensitivity to Egg Feeding

Abstract

Insulin resistance without and with obesity is associated with elevated LDL-C as well as elevated triglyceride and low HDL-C. The elevated LDL-C cannot be explained by dietary sensitivity, because the LDL-C rise with egg feeding is less in IR persons regardless of obesity status, probably attributable to diminished cholesterol absorption. The results suggest that dietary management of insulin resistance and obesity can focus more on restricting calories and less on restricting dietary fat.
