What protein intake range is commonly recommended for active Soldiers per kilogram body weight per day?

• A. 0.5 to 1.0 g/kg/day.
• B. Approximately 1.6 to 2.2 g/kg/day.
• C. 3.0 to 4.0 g/kg/day.
• D. 0.2 to 0.5 g/kg/day.

Answer: (B)

Active training increases the need for protein to support muscle repair, recovery, and adaptation. The range commonly recommended for active Soldiers is about 1.6 to 2.2 grams of protein per kilogram of body weight each day. This amount helps maximize muscle protein synthesis in response to both resistance and endurance work, supports preservation of lean mass during heavy training, and improves recovery between sessions. For example, a Soldier who weighs 80 kg would aim for roughly 128 to 176 grams of protein daily (80 × 1.6 to 80 × 2.2). Spreading protein intake across meals with high-quality sources (including essential amino acids and leucine) further enhances muscle rebuilding after training. Lower intakes like 0.5–1.0 g/kg/day are typically not enough for someone who is training hard, while very high intakes like 3.0–4.0 g/kg/day offer limited additional benefit for most people and can add unnecessary calories. The 0.2–0.5 g/kg/day range is insufficient for active individuals who need protein for repair and growth.
