Weight Loss Stopped-Confused!!!!!!!!

Hello.

I was banded two and a half years ago. I was 105 pounds overweight. I started out at 248 and now weight 176. I have gained about 6 pounds since January due to being too loose. I just went for a fill a couple of weeks ago. The problem I am having is I just can't seem to lose these last twenty pounds. I stopped losing right around 165 pounds. I keep gaining and losing the same 5 or 6 pounds. I have slacked a little on my exercise, but I am back on it. Before I was rapidly losing 1-2 pounds a week the first year and a half even by not really going by the high Protein low carb rule because I was just not hungry. Now it seems that no matter what I do this weight is not moving. My dietician told me that I should have no more than 25 grams of fat and 60 or under grams of carbs. To me this is almost impossible, being that most low carb foods are high in fat. I cannot exercise 6 days a week because I work a full time job and I have two grade school kids that need my attention. Has anyone else been through this and what helped you lose those last few pounds?:ohmy:
