Can Purple Sweet Potato Yoghurt Control Weight Gain?

摘要

We investigated the effect of purple sweet potato yoghurt to obesity parameters. Thirty male Wistar rats were randomly divided into 5 groups: normal control, negative control and three intervention groups with purple sweet potato yoghurt (200, 300, and 400 mL/day) for thirty days. The body weight of rats was weighed and weight gain, Lee Index were calculated afterwards. In the end of experiment, the rats were sacrificed to measure the distribution of visceral fat. The results were analysed using ANOVA test, and showed no significant difference between intervention group and normal control in mean body weight, weight gain, Lee Index, and mean total visceral fat. As conclusion, consumption of high fat diet together with purple sweet potato yoghurt in dose 200 mL/day tends to control stabilization body weight and accumulation of visceral fat compare to normal control.
