Which antipsychotic doesn't cause weight gain?

I had a psychotic episode recently. So my psychiatrist are going to prescribe me with the new medicine + Aripiprazole, Quetiapine and Lamotrigine. My question is: which antipsychotic doesn’t cause weight gain? Not including the medicine mentioned above.
