Obesity refers to an excess of body fat content causing metabolic and inflammatory disorders. Therefore, the aim of the present study was to investigate dose-dependent effect of rosuvastatin on the metabolic profile of diet-induced obesity in mice model study. A total number of 40 male Albino Swiss mice were used which divided into Group I: Control group, fed normal diet for 8 weeks (
n
= 10); Group II: High-fat diet (HFD) group, fed on HFD for 8 weeks (
n
= 10); Group III: HFD + 20 mg/kg rosuvastatin for 8 weeks (
n
= 10); and Group IV: HFD +40 mg/kg rosuvastatin for 8 weeks (
n
= 10). Anthropometric and biochemical parameters were estimated, including fasting blood glucose, lipid profile, fasting insulin, and glucose tolerance test (GTT). Mice on HFD fed showed a significant increase in the insulin resistance, body weight, deterioration of lipid profile and significant reduction in the β-cell function, and insulin sensitivity compared to the control
P
< 0.05. GTT and blood glucose level were significantly high in HFD fed group compared to the control group
P
< 0.05. Rosuvastatin in a dose of 40 mg/kg illustrated better effect than 20 mg/kg on the glucometabolic profile
P
< 0.05. Rosuvastatin may has a potential effect on reduction of glucometabolic changes induced by HFD with significant amelioration of pancreatic β-cell function in dose-dependent manner.
