The playbook and muscle file keep repeating one prescription: 1.2–1.6 grams of protein per kilogram of bodyweight, daily, while losing. This tool does the arithmetic and splits it into meals you can actually eat on a suppressed appetite.
How to use the number
Treat the range as a floor-and-ceiling, not a pass-fail line: most days inside it, protein front-loaded earlier per the playbook’s sequencing, and the cold-protein swaps on the days hot meat fails you. Current-weight-based targets are the pragmatic standard this range reflects; your clinician or dietitian can refine (adjusted-weight methods, kidney considerations) — which is exactly the kind of question worth bringing to a real intake visit.
Caveats, honestly
Educational arithmetic, not medical advice: kidney disease, pregnancy, and adolescent readers route protein targets through their clinicians (fertility file, adolescent file); and grams only count when paired with the resistance training that tells the body where to spend them.
