seriously, when I have plateaued is was ALL about my water intake. I've never been a big water drinker but I've really started guzzling it down and my weight now has been coming off consistently without any real effort otherwise. Yes, exercise is great but my biggest issue before the band was seriously just overeating. I also have an 11 cc band and am at about 8cc's myself. I felt good restriction for a few months around the 5-6cc mark...but then began plateauing again.
I have not consistently watched my water intake vs. my weight loss and the weeks where I know my water intake is low I don't lose much if not at all. But when I'm consistent about it drinking multiple bottles of water a day, I'll end up losing like 2-3 lbs a week.
Also, since being banded, I haven't eaten any real processed white sugar food. bread, tortillas, rice etc.... It just won't go down for me and I hate the feeling of having one bite of something and being totally stuffed so I just avoid it all together.
