Influência das Dietas Hipercalóricas sobre os Parâmetros de Obesidade, Dislipidemia e Hiperglicemia em Ratos

Hypercaloric diets were induced in rats to trigger obesity and analyze their biochemical levels. The rats were then compared with others fed on standard rations. Thirty rats, weighing 250-300 g, were used and divided into two groups: Standard Diet (SD) and Cafeteria Diet (CD). After 30 days, the groups were divided into SD, Diet Plus (PD) and CD; and biochemical tests were undertaken after 30 and 60 days. The animals were weighed, measured and the Lee Index and the microscopic analysis of visceral fat were taken. Weight, circumference, size and Lee Index increased in PD animals after 30 and 60 days of diet. In 30 days the chemical parameters increased total cholesterol and HDL levels of group SD when compared to PD and CD. Total cholesterol and HDL decreased after 60 days. Glucose levels increased after 30 days when compared to groups PD and CD. Group PD had a clear change in the microscopic analysis of visceral fat when compared to SD. Induced diet in animals had different reactions due to metabolism and induction time.
