Is it normal to lose your appetite after getting hit by a mound?

I'm looking into Maunza based on a friend's recommendation.
Looking at the reviews, I saw that many people said their appetite decreased significantly.

But I don't usually eat a lot anyway.
I'm a little worried that I might end up not eating enough.
I want to lose weight, but I think it would be a bit scary if it drained my energy as well.

I'm curious what it felt like in the beginning for those who have tried Maunza.
