Will i need a special diet after the gall bladder is removed?

I had to have emergency surgery to have my gall bladder removed. I have heard conflicting info about if i will need a special diet or not. my surgeon said i wont, and that it wont make me gain weight, i am looking to see if anyone else had theirs removed, and if they did, did they gain weight or need a special diet? not that i dont trust my surgeon, but just asking.
