People who understand Macros... I need your help

I've read in a lot of posts people suggesting to change the auto setting of the food macros to % 40/30/30 (Carbs/Fat/Protein)

So I did that. I felt It was not giving me a lot of protein and too many carbs.

Is this a good balance? Did I remember those numbers correctly?

I am really looking for healthy balance here, not XXXTREEM!!! weight loss.

Thanks in advance, nutrition gurus!
