High-fat, high-carbohydrate diet-induced experimental model of metabolic syndrome in rats
Purpose. The study is focused on development of high-fat, high-carbohydrate diet-induced experimental model of metabolic syndrome (MS) in rats.Materials and methods. The 6-week old Wistar rats (n = 20) were used for study. Rats were separated into control and experimental groups. The rats from the c...

The 6-week old Wistar rats (n = 20) were used for study. Rats were separated into control and experimental groups. The rats from the control group were fed standard rat chow.

High-fat, high-carbohydrate diet feeding in rats for 12 weeks led to BP elevation and increase in the adipose tissue/body weight ratio.
