How many calories are you supposed to have for day

that depends on how far you are in your post surgery... What phase you are at.

I'm three months out and I'm wanting to know how any calories

Check with your dietician. There are many caloric recommendations around but you have to find the one that is right for you. There are lots of factors to consider like gender, age, activity level, how far out you are, etc.

Some people are told to get to 1200 within a couple of months. There was no way I could have done that. I’m female, in my 50s, short & not very active. I was barely eating 900 by goal at 6 months & I could not physically eat more than I was. I only eat about 1300 now to maintain.

My surgeon and dietician didn't believe in counting calories, so they never gave me a limit. They said just eat small portions, focus on protein first and when you're full, stop eating.

That being said, I normally see at your stage people here talking about 900.

My program has 1200 for women, 1400 for men from day one.

It increases to 1600 for women and 1800 for men at 6 months.
