%X Background & Objective: Risk for heart disease, diabetes, and stroke increases with the number of the metabolic risk factors. In general, a person who has the metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as someone who does not have the metabolic syndrome. High-calorie-diet rodent models have contributed significantly to the analysis of the pathophysiology of the metabolic syndrome, but their phenotype varies distinctly between different studies and maybe is not very similar to a model of the metabolic syndrome in humans. We sought to create a model in this study close to the disease in humans.   Materials & Methods: Twenty male, Wistar rats were randomly assigned to the high-calorie diet group with 416 calories per 100 grams (researcher made) or the control diet group for 12 weeks. Weight changes, lipid profile, glucose, insulin levels, and QUICKI index (an indicator of insulin sensitivity) were measured. Weight changes were compared using the repeated measures and the independent t-test, and serum factors were compared using the independent t-test.   Results: There was a significant change in weight, glucose, insulin, and lipid profile except for HDL at the end of the study. The QUICKI index (0.34 ¡À 0.02 vs. 0.40 ¡À 0.01; p value <0.0001) suggested that insulin resistance had been created in the high-calorie diet group.   Conclusion: The present study demonstrates the ability to make diet-induced metabolic syndrome domestically.
