calories, pre and post

     My fellow co worker is post surgery 4 wks now, how many calories should she be taking in ?? Her doctor's coordinator wont answer any calls or questions so she is looking for answers from vetern sleever.  I feel that 1000 to 1200 calories should be enough to keep out of the starvation mode.

My nutritionist says to not count calorie intake or anything like that. They want us to focus on 3 meals a day, no snacks and 64oz of water. I try to keep my calories around 650/day. I'm 3 months post op and I don't think I could get more than 800 calories in per day so 1200 seems like a lot
