I am not certain what you can do as far as exercise goes, but have you tried walking, that is a good way to exercise, if that is ok for you to do.
You could start off with 10 minutes and then work your way up to 30 minutes per day, also swimming is a good one to do, I work with someone who has had a hip replacement and she was told swimming was a good exercise to do. Try it and good luck, as far as the food situation is concerned 1200 cals is ok as long as you get all your good foods from what you are eating.
Hope this helps
