How Much Protein Do You Really Need?
Protein requirements are highly individualized. The old blanket recommendation of "0.8g per kg of body weight" from the Recommended Dietary Allowance (RDA) represents the minimum to prevent deficiency — not the optimal amount for health or performance.
Modern sports nutrition research consistently supports higher protein targets for active individuals, with the most robust evidence pointing to 1.6–2.2g per kgof body weight for muscle building and strength athletes. Even for general health, higher protein intakes of 1.2–1.6g/kg support better weight management, muscle preservation, and metabolic health.
Protein Targets by Goal
| Goal | Protein Target | Example (70kg person) |
|---|---|---|
| Sedentary / General Health | 0.8–1.0 g/kg | 56–70g/day |
| Weight Loss (muscle preservation) | 1.4–1.8 g/kg | 98–126g/day |
| Recreational Exercise | 1.2–1.6 g/kg | 84–112g/day |
| Muscle Building | 1.6–2.2 g/kg | 112–154g/day |
| Endurance Athletes | 1.4–1.7 g/kg | 98–119g/day |
| Adults 65+ (anti-sarcopenia) | 1.2–1.6 g/kg | 84–112g/day |

Meal Timing and Distribution
Research supports distributing protein evenly across meals for maximal muscle protein synthesis. A single meal can only utilize approximately 40–50g of proteinefficiently for muscle building. Beyond that, excess protein is oxidized for energy.
Example meal distribution for 160g/day target:
- 🌅 Breakfast: 40g — 5 eggs + Greek yogurt
- 🌞 Lunch: 40g — Chicken breast + lentils
- 🌆 Dinner: 40g — Salmon + edamame
- 🌙 Pre-sleep snack: 40g — Cottage cheese + protein shake
