If you're wondering whether eating more fiber will make your weight loss faster, the answer is, probably not--not beyond increasing the size or frequency of your bowel movements. I'd say you should get more fiber to improve your colon health.
Weight loss has to do with the calorie intake, primarily. A loss of 1 to 2 pounds a week is considered a healthy rate of loss in that most of that weight is lost fat. If you are losing more than that, it's probably water weight along with some lean body mass loss.
So, take it easy! Be patient!
