Cardiovascular diseases account for the majority of deaths worldwide. Many of their risk factors have been identified but, for their continued study, research centering on new murine models is of interest. In this study, a high fat diet (HFD) and a normal diet (ND) (25 and 4.4% fat, respectively) were tested over a 40-day period to induce the same metabolic alterations in CF-1 mice in two separate experiments. The parameters measured for these effects corresponded to the weight of ingested food and water, to the weight of the mice and their selected organs (adipose tissue, gastrocnemius, liver and heart), to their biochemical profile (glycemia, blood uric nitrogen, uric acid, triglycerides, cholesterol, proteins and albumin) and to the percentage of fat in their livers. The biochemical profile of the CF-1 mice fed a diet high in fat but balanced in proteins (16.9%) showed statistically significant increases in glycemia, cholesterol and triglyceride levels. A statistically significant increase in the weight of adipose tissue was also observed. No statistically significant differences were observed in the muscular mass of either of the groups of mice, but a high percentage of fat was found in the liver. The results lead to the conclusion that CF-1 mice fed a HFD develop metabolic alterations that correspond to an equivalent metabolic syndrome. This is important in the evaluation of the effects of various interventions, such as food, exercise and molecules, on metabolic alterations in mice induced by the intake of a HFD.
