OBJECTIVE: Validate a model of high-fat diet-induced obesity, of low cost, easy reproducibility, that could express characteristics observed in human, and would enable subsequent therapy proposals. MATERIALS AND METHODS: Sixteen Swiss mice received a standard diet (DP) or high-fat diet (DH) for 10 weeks. RESULTS: Although the DP group had greater water (p < 0.01) and feed (p < 0.001) consumption, the DH group had greater body weight (p < 0.5) and adipose tissue gain (p < 0.001), favoring higher adiposity index (p < 0.001), glucose (p < 0.01), and area under the curve in the insulin (p < 0.001) and glucose (p < 0.01) tolerance tests. CONCLUSION: A high-fat diet-induced obesity model has been validated, which was also associated with insulin resistance and glucose intolerance after a period of 10 weeks.
