Yep, the wheels that come on that bike are made to handle minimal abuse. You're gonna need some stronger double wall rims.

Breaking spokes indicates that as the wheel rotates, the spoke at the bottom is completely losing tension, causing flex that eventually causes fatigue failure.
Solutions:
a) Higher spoke tension. If the spokes are already ~110Kgf, going higher may result in rims cracking around the spoke holes.
b) More spokes.

I am losing weight. But constantly every 2 weeks my spokes keep on breaking. I lost 30LBS this summer. What should I tell the LBS.

bicyclewheelwarehouse has some good deals on XT / MTX wheelset right now.
https://www.bicyclewheelwarehouse.com...de/cat_40.html
You could go XT / Rhynolite for about $60 cheaper
https://www.bicyclewheelwarehouse.com...-/prod_53.html
Is it just the rear wheel, or both?

200 lbs is considered heavy in cycing terms, let alone 300lbs. You may just have to get a tough wheelset built up. If your LBS can't do it try another.
Also - I had a similar problem once, the rear wheels kept breaking spokes, even though I wasn't doing anything rough. Turns out the back derailleur was bent inwards, and would smash into spokes when I was on the lowest gear of my cassette. Make sure it's not that before you sink money into better wheels that you'll just break again.
