Hi KV!

Of course, everyone is different, but I haven't had any problems following a low carb/high fat diet without my gallbladder. I know of at least one person here who does have a problem and needs to follow a lower fat (not low fat) version of low carb. It's not that your body is producing less bile than before, but that it's hitting your small intestine in a steady trickle instead of only being released by the gallbladder when fat is eaten. This can cause some problems and irritation for a few people, but only 10% of people have any dietary problems/restrictions following gallbladder removal.
What my surgeon basically told me after my gallbladder surgery is to eat whatever I wanted. If it bothered me, then I should avoid it. If it didn't bother me, I was good to go.
It seems that you're doing fine so far, so my opinion is that if it's not broken, don't fix it.
