Objective: The elevated body weight in post-menopausal state attributes to the reduced estrogen levels which is alleviated by resveratrol (RES) but its role in control rats is not well understood. The main objective of the study was to explore the effects of RES on the body weight of ovariectomized (OVX) female rats with controls and to relate their biochemical parameters.
Methods: Female Wistar rats weighing 200-300 g underwent bilateral ovariectomy (OVX) and were fed soya free diet (n = 8 rats per group). In all groups: (Control, Control + Resveratrol, OVX and OVX + Resveratrol) resveratrol was administered orally at a dose of 5 mg/kg/day for 1 month. Glucose and other biochemical parameters were examined.
Results: Significant reduction in the gain of body weight was observed in the control rats treated with resveratrol. Ovariectomy caused an escalation in gain of body weight due to loss of estrogen which was brought down with resveratrol. There was a slight dip in the blood glucose levels after resveratrol treatment.
Conclusion: Resveratrol significantly reduced the gain of body weight in the control rats and in OVX rats showing its antiobesogenic effects.
