Now, a few other medicines can cause drastic weight gain, the ones I'm familiar with include the SSRI Lexapro (Zoloft doesn't do that), the nerve pain gaba drugs, and sometimes benzodiazepines. But with
the benzos, you don't get huge weight gain
, just moderate. So, if you're on any of those drugs, consider switching kinds. And then of course you've got to exercise like a crazy person and increase proteins but cut back on carbs, especially white starches.
