I was sleeved Jan. 26,2011. I have been very faithful to my post op diet... I am getting all my protein requirements and water intake. I have not eaten any carbs ( breads, potatoes, pasta etc) I have only lost 20 lbs and 10 of that was during my pre op diet. I haven't lost any weight in a week. I am taking in about 600-800 calories daily. I try to walk almost everyday for about 30 minutes. So what gives?!? I am very frustrated and feel so disappointed! Can anyone tell me what to tweak?
