Background:
Currently, obesity affects over 600 million individuals and is responsible for numerous severe health conditions, particularly diabetes and metabolic syndrome. The objective of our study was to examine the impact of white tea, known for its potent antioxidant properties, on the reduction in body weight as well as the levels of leptin and asprosin.
Methods:
A total of 72 male Sprague-Dawley rats were randomly assigned to 9 groups, with each group consisting of 8 rats. The groups were partitioned into two in order to examine the preventative and therapeutic effects of white tea on obesity. During this study, the case groups were administered white tea together with a high-fat diet, whereas the positive control group was administered orlistat along with a high-fat diet through oral gavage. After the experiment concluded, the levels of leptin, asprosin, and insulin hormones were evaluated in serum samples collected from rats using the ELISA method.
Results:
The findings demonstrated that the administration of white tea led to a significant decrease in body weight, serum leptin, and asprosin levels, as well as oxidative stress indicators, in rats that were fed a high-fat diet.
Conclusions:
Utilizing natural chemicals, such as white tea, which possess minimal side effects and have powerful antioxidant activity, can mitigate the detrimental consequences associated with obesity.
