Are there any weight loss / diet pills that work?

I’ve been trying to lose weight for a while now, I go to the gym everyday and follow guidelines on what I eat. But I never see results, which leads me to lose motivation and ultimately gain more weight. I’m looking for something that isn’t a permanent thing, but just to help me kick start my weight loss and keep my motivation! If there’s any that you have taken and it worked (or didn’t) let me know! thanks
