High-Protein Muscle Gain Diet: What to Eat and When

Introduction: Protein Is the Foundation of Muscle Growth

Every set you complete creates microscopic muscle damage that must be rebuilt stronger. Protein supplies the amino acids for that repair. Many lifters either under-eat total protein or mistime it. A high-protein plan closes that gap—boosting recovery, metabolism, and lean gains with minimal fat.

Start by finding your target with the NutriFitCalc Protein Calculator.

Understanding Protein: The Science Behind Muscle Gain

• Supports muscle recovery and repair
• Increases metabolic rate
• Improves appetite control
• Helps retain lean mass during cuts

How Much Protein Do You Need?

Many active people seeking muscle gain do well with about 1.6–2.2 g/kg body weight/day. Example: a 70 kg lifter targets 112–154 g/day.

Balance your macros with the Calories Calculator and track status with the BMI Calculator.

Muscle-Gain Macros & Calories

Calorie target: aim for a modest surplus of about +10–15% above maintenance to add lean mass without excess fat.

When to Eat Protein: Timing Matters

• Breakfast: Break the overnight fast with ~30 g (eggs, Greek yogurt, whey) + complex carbs (oats, whole-grain toast).
• Pre-workout (1–2 h): ~25–30 g protein + moderate carbs (banana, brown rice).
• Post-workout (≤45 min): 30–40 g fast-digesting protein (whey, lean meat) + simple carbs for glycogen.
• Before bed: Slow protein (casein, cottage cheese, Greek yogurt) to reduce overnight breakdown.

Sample Macro Setup

Example: 75 kg male, strength training

• Maintenance ≈ 2,400 kcal → Gain target: 2,650–2,750 kcal (+10–15%)
• Protein: 150–165 g/day
• Carbs: 300–320 g/day
• Fats: 60–70 g/day

Choose Quality Proteins

Mix animal and plant proteins for a complete amino acid profile and better digestion.

Common Mistakes to Avoid

• Skipping the calorie surplus—too little food stalls growth
• Overusing shakes instead of whole foods
• Skipping breakfast or post-workout meals
• Under-fueling carbs for hard training
• Inconsistent meal timing

Helpful Supplements (Optional)

Training & Lifestyle Tips

• Lift 4–5 days/week with progressive overload
• Sleep 7–8 hours/night
• Hydrate: ~3 L/day
• Limit alcohol—it disrupts protein synthesis
• Track output with the Calories Calculator

Strength training + high-protein nutrition commonly adds ~1–2 kg lean mass per month (individual results vary).

Example Daily Schedule

Track Your Muscle-Gain Journey

• Reassess every 2 weeks: body measurements, progress photos
• Log strength (sets × reps × load); aim for gradual increases
• Use NutriFitCalc tools to tweak macros; if stalled, add +200–300 kcal/day (mostly carbs + protein)
