For optimal health you should be eating a balanced diet, somewhere in the neighborhood of 1/3rd of your calories from each: fat, carbs, protein. How efficiently your body processes the calories from each type is irrelevant, as you just find your TDEE and then move your intake up and/or down to reflect your goals.
Want to gain weight? Eat proportionately more of each macro.
Want to lose weight? Eat proportionately less of each macro?
Want to maintain? GTFO of here with that bullshit. Go tell lies on some other board.
Thus was solved any possible argument about calorie types, and yet this post will get (You)s attempting refutation.
