How to count macros with my new stomach

Hi everyone. My plan is to track macros when i reach 3-4 months post-op (currently at almost 2 months).

Not sure how to do this since we can eat so little and when you use the macro calculator, it gives very high numbers for calories, fat, protein, etc. Trying to figure out how I can adjust it.

I am currently getting about 400-450 calories in. I know it should be more but I’m still trying to figure out how to eat healthy and get the calories in. And frankly, it’s hard to eat a lot. And I was also told that constantly eating is bad so I try to have my 3 meals and one snack.

I know everyone is told something different by their doctors so not really sure what is the best at this point. I do want to get to the point where I a eating healthy but able to eat what I want and not feel deprived, which I feel is one of the many reasons I would sabotage my diets in the past and overeat. Thank you in advance for any words of advice!!!
