Step 4: Goal-Specific Modifications
Weight Loss (Fat Burning):
- Use "Very Active" calculation even if less active
- Higher protein preserves muscle during caloric deficit
- Increases satiety and metabolic rate
Muscle Building (Bulking):
- Use highest range for your activity level
- Consider 2.0-2.4g per kg for maximum growth
- Combine with resistance training program
Maintenance (General Health):
- Use standard calculation for activity level
- Focus on protein quality over quantity
- Consistent daily intake more important than peak amounts

Signs You're Getting Enough (or Too Little) Protein
Optimal Protein Intake Signs
Physical Indicators:
- ✅ Muscle mass maintained or growing
- ✅ Strong gym performance and recovery
- ✅ Stable energy levels throughout day
- ✅ Healthy hair, skin, and nails
- ✅ Good sleep quality
- ✅ Stable mood and mental clarity
Performance Markers:

- ❌ Hair loss or brittle nails
- ❌ Constant fatigue
- ❌ Poor workout recovery
Performance Issues:
- ❌ Declining strength in gym
- ❌ Extended muscle soreness
- ❌ Reduced endurance
- ❌ Difficulty concentrating
If experiencing these: Increase protein intake by 20-30g daily and monitor for 2-3 weeks.
Excess Protein Concerns
Signs of Too Much Protein:
- Digestive issues (bloating, gas)
- Kidney strain (in predisposed individuals)
- Dehydration
- Expensive urine (literally urinating money)
Safe Upper Limits:
- General population: 3.5g per kg body weight
- Healthy kidneys: Up to 4.0g per kg body weight
- Most men: 2.0-2.4g per kg is optimal ceiling
Protein Timing for Maximum Results
The Anabolic Window
Post-Workout Protein Timing:
- Optimal: Within 30 minutes post-exercise
- Good: Within 2 hours post-exercise
- Amount: 30-40g high-quality protein (like Retaur Whey)
- Why: Muscle protein synthesis elevated for 3-5 hours
Meal Timing Strategy
Every 3-4 Hours Rule:
Research shows muscle protein synthesis peaks 1-2 hours after protein consumption and returns to baseline by 3-4 hours.
Practical Schedule:
- 7 AM: Breakfast protein
- 11 AM: Mid-morning protein
- 3 PM: Afternoon protein
- 7 PM: Post-workout protein
- 10 PM: Evening protein (optional)
Before Bed Protein
Why It Matters:
- 7-8 hours without protein causes muscle breakdown
- Slow-digesting proteins provide all-night amino acids
- Supports growth hormone production during sleep
Best Options:
- Casein protein powder
- Greek yogurt with nuts
- Retaur Protein Yogurt before lighter evening meals
Common Protein Myths Debunked
Myth 1: "Too Much Protein Damages Kidneys"
Truth: Healthy kidneys can handle high protein intakes (up to 4g per kg body weight). Only people with existing kidney disease need to limit protein.
Evidence: Studies on athletes consuming 3-4g per kg for years show no kidney damage.
Myth 2: "You Can Only Absorb 25g Protein Per Meal"
Truth: Your body can absorb much more, but muscle protein synthesis plateaus around 25-40g per meal.
Reality: Excess protein is used for energy or other bodily functions, not "wasted."
Myth 3: "Plant Proteins Are Inferior"
Truth: While plant proteins often have lower biological values, combining sources or consuming larger amounts achieves similar results.
Strategy: Whey protein (like Retaur) is more efficient, but plant proteins work with proper planning.
Myth 4: "Protein Makes You Bulky"
Truth: Protein alone doesn't build muscle - resistance training + protein + adequate calories does.
Reality: Protein actually supports lean body composition and fat loss.
Myth 5: "Expensive Protein Is Always Better"
Truth: Protein quality matters more than price. Retaur offers premium quality at local prices, outperforming many expensive imports.
Frequently Asked Questions
How much protein should a 70kg Nigerian man consume daily?
A 70kg man needs 110-155g protein daily depending on activity level. Sedentary: 110g, Active: 130g, Very Active: 155g. Add 10-20% if over 30 years old.
Can I get enough protein without supplements?
Yes, but it requires careful meal planning. Retaur products make it easier and more cost-effective to meet daily targets consistently.
What happens if I don't eat enough protein?
Insufficient protein leads to muscle loss, slower recovery, decreased strength, poor immune function, and reduced metabolism over time.
Is it better to spread protein throughout the day?
Yes, consuming 25-40g protein every 3-4 hours optimizes muscle protein synthesis better than large amounts in fewer meals.
How much protein is too much?
For healthy men, up to 3.5g per kg body weight is safe. Most men optimize results between 1.6-2.4g per kg body weight.
Do older men need more protein?
Yes, men over 40 need 20-25% more protein due to decreased protein synthesis efficiency and accelerated muscle loss.
Your Personalized Action Plan
Step 1: Calculate Your Exact Needs
Use This Formula:
1. Determine activity level (sedentary to very active)
2. Apply base calculation (1.0-2.0g per kg)
3. Add age adjustment (+10-25% if over 30)
4. Factor in goals (maintenance vs muscle building)
Example Calculation (35-year-old, 80kg, moderately active man):
- Base: 80kg × 1.6g = 128g
- Age adjustment: 128g + 10% = 141g
- Goal (muscle building): 141g + 15% = 162g daily target
Step 2: Plan Your Protein Sources
Daily Protein Budget (162g example):
- Retaur Whey Protein: 50g (2 scoops = 42g protein)
- Retaur Protein Yogurt: 20g (1 serving = 18g protein)
- Whole foods: 90g (chicken, fish, eggs, beans)
- Incidental: 12g (rice, bread, vegetables)
Step 3: Time Your Intake
Priority Times:
1. Post-workout: 30-40g within 30 minutes
2. Morning: 20-25g to break overnight fast
3. Before bed: 25g slow-digesting protein
4. Between meals: 20-25g every 3-4 hours
Step 4: Track and Adjust
Week 1: Use phone app to track actual intake
Week 2: Adjust portions to hit target consistently
Week 4: Assess energy, recovery, and strength gains
Week 8: Fine-tune based on results and goals
Conclusion
Understanding how much protein men need isn't just about hitting a number - it's about optimizing your body's ability to build and maintain muscle, recover from workouts, and support overall health throughout your life.
Key Takeaways:
- Most Nigerian men need 1.6-2.0g per kg body weight daily
- Age, activity, and goals significantly affect requirements
- Quality and timing matter as much as quantity
