Hi imatine,
If the pale stools continue you should consult with a physician and rule out a bile duct blockage. It is possible that scar tissue is forming due to the recent removal of your gallbladder two months ago. It is very good news that your liver functions are good right now. I'm not a doctor, but I would think the diet you described may affect a stools firmness or the frequency of movements, but it shouldn't affect the color. Hopefully this issue has already resolved and you are back to normal.
