Green tea consumption leads to weight loss and decreased levels of fasting insulin and free testosterone in overweight women with polycystic ovarian syndrome.
In the research methodology, a two-group, double-blind, randomized clinical trial was conducted among 60 overweight women with polycystic ovarian syndrome in Isfahan. The participants were randomly classified into two groups, one receiving green tea (the experimental group) and the other receiving a placebo (the control group). Comparisons of levels of free testosterone hormones and fasting insulin were made at the start of the study and 12 weeks later, along with measurements of participant weight before and after the study.
Discussing the results, the comparison showed no initial significant difference in participant weight, fasting insulin or free testosterone levels between the two groups. However, after the 12-week period, notable differences were observed. The green tea group showed significant weight loss and declines in both fasting insulin and free testosterone levels compared to the placebo group.
