homeostasis/metabolism
• high-fat diet fed mice exhibit reduced fasted and fed serum-free fatty acids
• mice fed a high-fat diet exhibit a minor increase in energy expenditure independent of any altered activity or respiratory quotient
• mice fed a high-fat diet exhibit increased glucose clearance after 16 weeks on the high-fat diet
• mice fed a high-fat diet exhibit increased insulin sensitivity after 16 weeks on the high-fat diet
• mice are resistance to high-fat diet induced metabolic disease
• however, mice fed a chow diet develop normally, exhibit normal white blood cell counts, and appear healthy, with no alterations in body weight, food intake, glucose tolerance, insulin sensitivity, or plasma-free fatty acid levels

growth/size/body
• mice fed a high-fat diet exhibit a slightly reduced body weight gain compared to controls, despite similar food intake levels, although mice do become obese

adipose tissue
• adipocyte size is reduced in epididymal fat from high-fat diet fed mice compared to controls on the same diet

cellular
• naive bone marrow derived macrophages from high-fat diet fed mice show elevated basal respiration and spare respiratory capacity
• naive bone marrow derived macrophages from high-fat diet fed mice show elevated basal and spare respiratory capacity and ATP-turnover
• increase in oxygen consumption rate of bone marrow derived macrophages from high-fat diet fed mice
• bone marrow derived macrophages from high-fat diet fed mice exhibit an increase in intracellular hydrogen peroxide and an increase of cytosolic reactive oxygen species

immune system
• IL-1 beta secretion by bone marrow derived macrophages from high-fat diet fed mice is reduced
• IL-6 secretion by bone marrow derived macrophages from high-fat diet fed mice is reduced
• TNF-alpha secretion by bone marrow derived macrophages from high-fat diet fed mice is reduced
• epididymal fat from high-fat diet fed mice shows improvements in metaflammation, with near absence of crown-like structures, reduced adipocyte size, and a reduction in macrophage infiltration
• adipose tissue from high-fat diet fed mice shows a 2-fold reduction in proinflammatory CD11c+ and CCR2+ macrophage infiltrates and an increase in numbers of protective M2-like MGL+ macrophages

liver/biliary system
• mice fed a high-fat diet exhibit attenuated liver steatosis compared to controls

cellular
• primary hepatocytes from high-fat diet fed mice exhibit increased basal, spare as well as maximal respiratory capacity
• primary hepatocytes from high-fat diet fed mice exhibit increased basal, spare as well as maximal respiratory capacity, however, no changes in coupling efficiency, mitochondrial DNA content, mitochondrial mass or respiratory chain stoichiometry were seen
• increase in oxygen consumption rate of primary hepatocytes from high-fat diet fed mice
• an approximate 50% increase in intracellular hydrogen peroxide and an increase of cytosolic reactive oxygen species

homeostasis/metabolism
• mice fed a high-fat diet show improved serum levels of alanine transaminase (ALAT), aspartate transaminase (ASAT), and ASAT/ALAT ratios compared to controls, indicating less hepatotoxicity
• mice fed a high-fat diet show improved serum levels of alanine transaminase (ALAT), aspartate transaminase (ASAT), and ASAT/ALAT ratios compared to controls, indicating less hepatotoxicity
• mice fed a high-fat diet exhibit increased insulin sensitivity
• however, mice fed a high-fat diet show similar weight gain and glucose tolerance as controls
• mice exhibit resistance to high-fat diet-induced metabolic disease
• however, mice fed a chow diet develop normally, exhibit normal liver morphology and serum parameters, normal glucose and insulin tolerance

liver/biliary system
• mice fed a high-fat diet exhibit attenuated liver steatosis compared to controls
