Introduction

Physiol Rep. Likewise, serum concentration of cholesterol is also an important parameter for the assessment of obesity, since the greater the availability of serum cholesterol, the greater the deposition of fatty acids into the adipose tissue and the liver [ 33 ]. These differences are also apparent in many other murine models of human disease.

A couple of the responses concerned the issue that the DIO series of diets differ not only in their fat content but also in other components that may be important in terms of driving effects on metabolic health.

Overall, the message from the board of IJO was that we encourage researchers to try and mimic in rodent studies aspects of the diet that are similar to those found in cat, in the hope this will provide better insights into the causes and consequences of obesity. High fat HF diet can lead to increased body weight and diabetes in various strains of mice and rats, while different strains exhibit different responses to a varying degree.

Skeletal muscle of HFD mice succumbs to many of the above-mentioned pathologies: insulin resistance, lipotoxicity from excessive lipid storage, and inflammation.
