Protein Recommendations Reference
| Goal / Population | Range (g/kg/day) | Notes |
|---|---|---|
| General Health | 0.8 – 1.2 | Sedentary adult RDA: 0.8 g/kg. Active adults benefit from more. |
| Fat Loss (preserve muscle) | 1.6 – 2.4 | Higher protein during deficit preserves lean mass and increases satiety. |
| Muscle Gain / Strength | 1.6 – 2.2 | Optimal hypertrophy range from ISSN position stand & meta-analyses. |
| Endurance Athlete | 1.2 – 1.6 | Long-distance runners, cyclists, triathletes need 1.2–1.6 g/kg. |
| Older Adult (65+) | 1 – 1.5 | Higher protein helps prevent sarcopenia (PROT-AGE recommendations). |
| Pregnancy | 1.1 – 1.3 | Additional 25 g/day in 2nd & 3rd trimesters; ~1.1 g/kg total. |
| Lactation | 1.2 – 1.5 | Increased needs for milk production: ~1.3 g/kg. |
