Side effects of traditional Korean medicine diet

You seem to have lost a lot of weight while I wasn't looking.

When asked how it was removed, they said they took herbal medicine.

Is exercise just about walking about 10,000 steps?

So when I asked if it was okay, they said they completely lost their appetite.

However, acquaintances who took diet pills experienced indigestion, so they were also prescribed stomach medication.

It seems to be effective, so I'm interested, but I'm worried about the side effects that come with it.

Are there diet pills with fewer side effects?
