BMI — screen weight status, then track progress with diet quality (scan packaged foods).
TDEE — estimate daily calories, then choose higher-scoring foods to hit targets without excess sugar or sodium.
Sugar limit — stay inside AHA limits; compare grams per 100g on labels while scanning.
NOVA — flag ultra-processed foods; cleaner scores usually mean less processing.
