Do diet supplements work?

A friend recommended it to me, so I'm thinking about buying some diet supplements, but honestly, I'm not sure if they'll work...

But I thought it would be better than not eating, so I bought some diet supplements and started taking them.

I haven't really felt it yet... haha

Should I continue taking diet supplements since they are not cheap?

I'm going to try just one bottle for now, but I wonder if anyone has experienced any effects...

I feel like I should eat it like I'm taking some kind of nutritional supplement lol Dieting is hard ㅠㅠ
