Abstract

The present study was performed to assess anti-obesity effects of raw pineapple juice in high fat diet (HFD)-induced fatness. Based on food type, rats were divided into normal diet and HFD groups. When animals of HFD group become obese, they were given pineapple juice along with either HFD or normal diet. Blood biochemistry, liver and muscle gene expressions were analyzed. HFD induced significant elevations in body weight, body mass index (BMI), body fat accumulation, liver fat deposition and blood lipids while juice restored these parameters near to their normal values. Juice significantly decreased serum insulin and leptin while adiponectin was increased. Juice administration downregulated the increment of FAS and SERBP-1c mRNA expression in liver and upregulated HSL and GLUT-2 expressions. The muscular lipolytic CPT-1 expression was upregulted by juice treatment. Pineapple juice, therefore, may possibly be used as anti-obesity candidate where it decreased lipogenesis and increased lipolysis.
