What Should I Eat to Build Muscle? Protein Targets, Meal Timing, and Sample Plan

Building muscle requires a calorie surplus and optimized protein intake. Here is exactly what to eat, when to eat it, a full 2,800-calorie muscle-building day, and the leucine-rich foods that drive muscle protein synthesis.

Medically reviewed by Dr. Emily Torres, Registered Dietitian Nutritionist (RDN)

Building muscle requires two non-negotiable nutrition inputs: a calorie surplus to provide energy for new tissue and sufficient protein to supply the amino acids that form that tissue. A landmark review by Schoenfeld and Aragon (2018, Journal of the International Society of Sports Nutrition) confirmed that protein intakes of 1.6 to 2.2 g/kg/day maximize muscle protein synthesis (MPS) in resistance-trained individuals. But the details matter. Which protein sources deliver the most leucine? When should you eat relative to training? And what does a full muscle-building day actually look like?

This guide answers all of it with specific foods, exact portions, and a complete 2,800-calorie day you can follow starting today.

How Many Calories Do You Need to Build Muscle?

You need a calorie surplus of approximately 350 to 500 calories above your maintenance level to maximize muscle gain while limiting unnecessary fat gain (Slater et al., 2019, Sports Medicine). For most men training seriously, this lands between 2,600 and 3,200 calories per day. For most women, between 2,000 and 2,600.

Eating too far above maintenance does not accelerate muscle growth. It accelerates fat gain. A controlled study by Garthe et al. (2013) found that athletes on a moderate surplus gained the same amount of muscle as those on a large surplus but gained significantly less fat.

What Macros Should I Hit to Build Muscle?

Macronutrient Target Purpose
Protein 1.6-2.2 g/kg body weight Provides amino acids for MPS, especially leucine
Carbohydrates 4-7 g/kg body weight Fuels training, replenishes glycogen, supports recovery
Fat 0.8-1.2 g/kg body weight Supports testosterone production and overall health
Calories Maintenance + 350-500 kcal Provides energy surplus for tissue growth

For an 80 kg lifter targeting 2,800 calories, that works out to roughly 160 g protein, 370 g carbs, and 80 g fat.

High-Protein Foods Ranked by Leucine Content

Leucine is the amino acid that directly triggers MPS through the mTOR pathway (Norton and Layman, 2006). You need approximately 2.5 to 3 g of leucine per meal to maximally stimulate MPS. Here are the best sources:

Food (per 100 g cooked) Protein (g) Leucine (g) Calories
Whey protein isolate 90 10.0 370
Chicken breast 31 2.5 165
Lean beef (sirloin) 29 2.4 190
Turkey breast 30 2.3 157
Tuna (canned in water) 26 2.1 116
Salmon 20 1.8 208
Greek yogurt (0% fat) 10 0.9 59
Eggs (2 large) 13 1.1 155
Cottage cheese (low fat) 12 1.1 72
Soybeans (cooked) 17 1.3 173
Lentils (cooked) 9 0.6 116
Milk (whole) 3.3 0.3 61

Notice that animal proteins generally deliver more leucine per gram of protein. If you eat plant-based, combining sources and slightly increasing total protein intake compensates for lower leucine density.

Meal Timing for Muscle Protein Synthesis

MPS research (Areta et al., 2013, Journal of Physiology) shows that distributing protein across 4 to 5 meals of 0.4 to 0.55 g/kg each produces a stronger anabolic response than cramming protein into 1 to 2 large meals. For an 80 kg person, that means 30 to 45 g of protein per meal, spread every 3 to 5 hours.

Optimal Meal Distribution

Meal Timing Protein Target Purpose
Breakfast Morning 30-40 g Break overnight fast, stimulate first MPS peak
Pre-workout 1-2 hours before training 30-40 g Amino acid availability during training
Post-workout Within 2 hours after training 30-40 g Maximize post-exercise MPS window
Dinner Evening 30-40 g Sustained amino acid supply
Pre-bed 30-60 minutes before sleep 30-40 g Casein-rich to sustain MPS overnight

Pre-Workout Meals That Fuel Performance

Your pre-workout meal should be eaten 1 to 3 hours before training and include carbohydrates for energy plus protein for amino acid availability:

  • 150 g chicken breast + 200 g white rice + vegetables (eaten 2-3 hours before)
  • 2 slices whole grain bread + 2 eggs + banana (eaten 1-2 hours before)
  • Greek yogurt + oats + honey + berries (eaten 1-2 hours before)

Post-Workout Meals That Maximize Recovery

The anabolic window exists but is wider than the old "30-minute" myth. Schoenfeld et al. (2013) concluded that consuming protein within roughly 2 hours post-exercise is beneficial, but the urgency depends on when you ate your pre-workout meal. If your last meal was 3 to 4 hours ago, eat sooner. If you trained 1 to 2 hours after eating, you have more flexibility.

Strong post-workout options:

  • 2 scoops whey protein + banana + oats shake
  • 200 g lean beef stir-fry with rice and vegetables
  • 170 g Greek yogurt + granola + fruit + scoop of whey

Frequently Asked Questions

How much protein do I need per day to build muscle?

Current evidence supports 1.6 to 2.2 g per kg body weight per day (Schoenfeld and Aragon, 2018). For an 80 kg person, that is 128 to 176 g. Distributing this across 4 to 5 meals of 30 to 45 g each optimizes muscle protein synthesis.

Do I need to eat immediately after my workout?

Not necessarily. The post-exercise anabolic window is real but spans roughly 2 hours, not 30 minutes (Schoenfeld et al., 2013). If you ate a protein-rich meal 1 to 2 hours before training, there is no need to rush to eat the second you finish.

Can I build muscle in a calorie deficit?

Yes, but only under specific conditions: beginners, people returning after a break, or those carrying significant body fat. For trained individuals, a surplus is needed to optimize muscle gain (Slater et al., 2019). The surplus does not need to be large. An extra 350 to 500 calories is sufficient.

What should I eat if I train in the morning before breakfast?

Have a fast-digesting protein source like a whey shake or a banana with Greek yogurt 30 to 60 minutes before training if possible. If you truly cannot eat, ensure your post-workout meal is protein-rich and consumed within an hour of finishing. Your previous evening meal also provides amino acids that persist into the morning.

Is chicken breast the best food for building muscle?

Chicken breast has one of the best protein-to-calorie ratios and is rich in leucine, making it excellent. But variety matters for micronutrient coverage. Rotate between chicken, fish, lean beef, eggs, dairy, and legumes. The best muscle-building food is the high-protein food you will consistently eat.

How do I gain muscle without gaining too much fat?

Keep your surplus moderate (350 to 500 kcal above maintenance), prioritize protein, and track your intake. If you are gaining more than 0.5 kg per week, your surplus is likely too large. Nutrola's daily tracking makes it easy to spot when calorie creep pushes you from a lean bulk into unnecessary fat gain.
