Formula and methodology
Formula: Protein grams = weight x target; fat grams = calories x fat percent / 9; carbohydrate grams = remaining calories / 4.
The output exposes every planning assumption rather than presenting a universal macro prescription.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
