Fitday & NUT???

Hi All,     I have been on the boards many times just complaining; but now I have truly committed myself to doing something about it. I have went back to fitday; I am entering and watching everything I eat! I have been hitting the treadmill and rec. bike at 45-60 min. daily. I burn on average 500-600 calories a day. I take in only about 1200! I am increasing my water intake as well; and doing my protien shakes too. So why are my scales not budging a bit? My own family DR just blew me off! Do I need to return to the NUT at my clinic? I am also keeping my carbs at 30 percent or less? What are good carbs, bad carbs; and how many should we be worring about?? My family Dr did say my cardio won't help me lose much anymore; he said need to do weight trainning. I can't do wait trainning right now do to be in therapy for cerical neck problems. Do bands work well to tone and bulid muscle?     I have been on this plateau for about 5 months now; and it is taking over my confidence and happiness! I get 80-100 grams of protien daily; to much or to little? I am lost for some real answers! Can anyone relate, give me some help; or advise me where to go from here? Thanks, Judy R  P.S.  I am 1yr and 2 months post RNY..
