How Much Protein Do You Really Need?
A science-backed guide to protein requirements for different goals: weight loss, muscle building, and maintenance.
The Protein Question
"How much protein should I eat?" It's one of the most common nutrition questions. Let's break down the science.
The RDA vs. Optimal Intake
The Recommended Dietary Allowance (RDA) for protein is 0.8g per kg of body weight. However, this is the minimum to prevent deficiency-not the optimal amount for your goals.
Protein Needs by Goal
For Weight Loss: - 1.2-1.6g per kg body weight - Higher protein preserves muscle during calorie deficit - Increases satiety (keeps you fuller longer)
For Muscle Building: - 1.6-2.2g per kg body weight - Spread intake across 4-5 meals - Consume within 2 hours post-workout
For Maintenance: - 1.0-1.2g per kg body weight - Focus on protein quality - Include complete protein sources
Best Protein Sources
| Source | Protein (per 100g) | Notes | |--------|-------------------|-------| | Chicken Breast | 31g | Lean, versatile | | Greek Yogurt | 10g | High calcium | | Eggs | 13g | Complete protein | | Salmon | 25g | Omega-3s | | Lentils | 9g | Plant-based |
Practical Tips
- Track for a week: Use Macroly to see your current intake
- Add protein first: Build meals around protein sources
- Prepare in bulk: Meal prep protein to ensure consistency
- Consider timing: Spread protein throughout the day
Remember: More isn't always better. Focus on hitting your target consistently rather than overdoing it.
