Why do antipsychotic drugs cause weight gain?

Jennifer asked the Naked Scientists:

Hi Naked Scientists! I have a question: I was just reading an article about anti-psychotic medications, and they were talking about significant weight gain as a common side effect. How do these drugs do this? Can these side effects help us better understand problems like obesity?

It's great to have Chris and Helen and Kat back, though Ben and Diana did a great job filling in!

Thanks a lot

p.s. I always have to laugh when I hear "Imagine listening to the Naked
Scientists in bed..." because I'm ALWAYS lying in bed when the guy says

What do you think?

Weight gain could due to antipsychotics altering the metabolism...

Inactivity caused by the sedative effect of antipsychotics could also result in weight gain.
