The control group of animals received a standard diet (Global Diet 2018S from Harlan Teklad). The HF group received a diet with 35% fat (Diet TD.03584 from Harlan Teklad) and the KO group was fed with the above reported HF diet supplemented with 2.5% (w/w) KO. Fatty acids were extracted from the three diets and analyzed by gas-liquid chromatography. Energy content was calculated using 4 kcal/g for protein and carbohydrate and 9 kcal/g for lipid.
