I have gallbladder stones. Need diet advice.

(24M 6'1" SW:317 CW:230 GW:195)

Hi, I've been doing great for a while with my food, counting it, etc. Unfortunately, I now have gallstones and it's most likely due to rapid weight loss so now I need to alter my diet before getting surgery to have the gallbladder removed (and of course after as well) by having a "low-fat diet" which was told to me by 2 doctors to do but they didn't tell me exactly what to eat and said to look online. I looked on various sites that tell me what to avoid but give no examples of what to eat.

edit: Thank you! Here's the list I found: http://www.everydayhealth.com/gallbladder/diet/

I've been in the ER twice now in the past 4 days because I had extreme pain from the gallbladder and can't get surgery for another 2-4 weeks. I've been very scared on what to eat so all I've had in the past 24 hours were no-fat yogurts, cauliflower, and bananas. Please help in the meantime?
