Fat Loss (preserve muscle)1.62.4Higher protein during deficit preserves lean mass and increases satiety.
Muscle Gain / Strength1.62.2Optimal hypertrophy range from ISSN position stand & meta-analyses.
Endurance Athlete1.21.6Long-distance runners, cyclists, triathletes need 1.2–1.6 g/kg.
Older Adult (65+)11.5Higher protein helps prevent sarcopenia (PROT-AGE recommendations).
Pregnancy1.11.3Additional 25 g/day in 2nd & 3rd trimesters; ~1.1 g/kg total.
