This is an author-defined allocation, not verbatim ISSN requirements or a physiological minimum for fat. No complete plan is displayed if protein and fat exceed calories. Adult fat AMDR 20–35% is a separate reference range, not an individual prescription.

How it is calculated

Protein presets: 1.8–2.2 g/kg for loss, 1.4–1.8 for maintenance, 1.8–2.4 for gain; fat 0.8–1.2 g/kg. Uses range midpoints; carbohydrate is the calorie remainder with 4/9/4 kcal/g factors.

Formula

Protein(g) = weight × goal factor; Fat(g) = weight × 0.8…1.2; Carbs(g) = (calories − protein × 4 − fat × 9) / 4

Limits of the method

This is an author-defined allocation, not verbatim ISSN requirements or a physiological minimum for fat. No complete plan is displayed if protein and fat exceed calories. Adult fat AMDR 20–35% is a separate reference range, not an individual prescription.
