Whole Egg Consumption Impairs Insulin Sensitivity in a Rat Model of Obesity and Type 2 Diabetes.

Background: The literature regarding the relation between egg consumption and type 2 diabetes (T2D) is inconsistent and there is limited evidence pertaining to the impact of egg consumption on measures of insulin sensitivity.

Objectives: The aim of this study was to investigate the effect of dietary whole egg on metabolic biomarkers of insulin resistance in T2D rats.

Methods: Male Zucker diabetic fatty (ZDF) rats ( = 12; 6 wk of age) and age-matched lean controls ( = 12) were randomly assigned to be fed a casein- or whole egg-based diet.
