Medicine weight gain. How is abilify?

I am a paranoid schizophrenic. I am currently taking Loxapine 10mg/day. I have gained 10kg on it. Want advice switching medication that will not cause that much weight gain. Have already taken Risperidone in the past which also caused major weight gain. So now I want advice as to which antipsychotic to try that may not cause weight gain. Don't advice me on how my mental health is more important that how I look. That is none of your business. I want to continue taking my medication, but I would like to try different medications until I find one that doesn't cause weight gain, as there are many people for whom this process has worked. Also loxapine is difficult to find in Delhi, so I'd like a medicine that is easily available in Delhi. How is abilify? I know a lot of people gain weight on it, but for some people it is weight neutral. Please advice.
