What effects do diet pills have that help with weight loss?

I'm working out hard and also following a diet...

I can't lose weight, haha.

Doing exercise and dieting like before... now...

It was so overwhelming and difficult~~

I want to try dieting a bit more comfortably..

I only knew about diet pills, but it seems diet tablets are also available~~

It seems more comfortable and better to eat..

What are the effects of diet pills?

Is it suppressing your appetite..?

Is it helping to burn fat?

Will the symptoms come back if I stop taking the medication?

This part is what I'm most curious and worried about..ㅜ

You should do both exercise and diet simultaneously...

I think I would be very upset if I quit medication and then experienced a relapse.
