Ketogenic versus Western and standard chow diets favorably alters fat deposition and serum biomarkers in rats

Methods Male Sprague-Dawley rats (~9-10 weeks of age) were provided isocaloric amounts of either a KD (5.2 kcal/g, 20.2% protein, 10.3% carbohydrate, 69.5% fat; n = 50), WD (4.5 kcal/g, 15.2% protein, 42.7% carbohydrate, 42.0% fat; n = 66), or StdChow (3.1 kcal/g, 24.0% protein, 58.0% carbohydrate, 18.0% fat n = 10) for 6 weeks with daily food intake and body weights recorded. After the animals were sacrificed, 4 different fat depots were weighed and serum was collected in subsets of each diet for further investigation.
