Herbal medicine diet effect~

In the past, traditional Korean medicine diet pills were popular in the company ~ but most of the older women seemed to succeed after taking them ~ At that time, I moved to a different department and started hanging out with the older women, and during breaks, I ate various things, so I gained a lot of weight ㅎ I also tried appetite suppressants, and I lost about 10 kilograms, but when I stopped, I gained weight again due to the yo-yo effect ㅠ A few years later, I tried a pill from another Korean medicine clinic, but maybe because I didn't put in effort, I neither lost nor gained weight ㅠ But these days, I hear that people are succeeding by taking pills here and there, so I want to try them too ㅠㅠ What kind of pills are everyone taking?
