For muscle gain, target 1.6–2.2 g protein per kg body weight each day, split into 3–5 meals with 0.25–0.4 g/kg soon after training.
Muscle grows when training and food line up. Resistance work provides the signal. Protein supplies amino acids for repair and new tissue. Calories and sleep round out the plan. This guide gives clear daily targets, shows how to split them across meals, and offers easy math for any body size.
Daily Protein Targets To Build Muscle Safely
Most lifters land in a sweet spot across a range, not a single number. A practical daily goal sits between 1.6 and 2.2 grams per kilogram of body weight. That range covers men and women, beginners and veterans, and both bulking and slow-cut phases. People carrying more body fat can aim toward the lower end when dieting; lean, hard-training athletes can push to the top of the range.
The government baseline for healthy adults is 0.8 g/kg. That level meets basic needs in steady weight conditions, but it leaves little room for growth during hard training. Strength and physique programs raise the bar. The targets below match what many trials report during resistance work. For deeper reading, see the National Academies’ chapter on protein needs (protein RDA).
Quick Range Table By Body Size
Use this table as a starting point. Pick the row closest to your current weight. Then fine-tune based on goal, appetite, and recovery.
| Body Weight (kg) | 1.6 g/kg (g/day) | 2.2 g/kg (g/day) |
|---|---|---|
| 50 | 80 | 110 |
| 60 | 96 | 132 |
| 70 | 112 | 154 |
| 80 | 128 | 176 |
| 90 | 144 | 198 |
| 100 | 160 | 220 |
| 110 | 176 | 242 |
Why This Range Works
Muscle tissue grows when total daily protein hits a level that covers training stress and daily turnover. Across many trials, gains rise with higher intake up to a point, then level off. The leveling tends to sit near the lower half of the range above. Pushing to the top can still help during cuts, very high volume weeks, or when snacks are small.
Per-meal hits also matter. A dose around 0.25 to 0.40 g/kg jump-starts protein building for a few hours. Hitting that dose 3 to 5 times per day lines up with the daily total. After lifting, one of those meals can come from a shake or regular food. Sports nutrition groups publish detailed guidance on this topic; a helpful overview sits in the JISSN position stand.
How To Plan Your Day
Start with body weight. Multiply by 1.6 to set your floor. Multiply by 2.2 to set your ceiling. Land anywhere inside based on hunger, training load, and overall calories. Then split the total across main meals and one snack. Add carbs around training for better performance and to spare protein from being burned for fuel.
Meal Split Basics
- 3 meals + 1 snack: Breakfast, lunch, dinner, plus a shake or yogurt bowl.
- Per meal target: Around 0.3 g/kg works well for most people.
- Post-workout: One meal or shake within a couple of hours after training fits the plan.
- Hydration: Drinks help digestion and recovery. Add salt if sessions run long and sweaty.
Sample Day At 70 kg (Target ~112–154 g)
- Breakfast: Eggs on toast with fruit (~30–40 g).
- Lunch: Chicken rice bowl with veggies (~30–40 g).
- Snack: Greek yogurt with oats or a whey shake (~20–30 g).
- Dinner: Lentil pasta with beef or tofu (~30–45 g).
Pounds-Based Math (No Calculator Needed)
If you think in pounds, multiply body weight by 0.73 to hit ~1.6 g/kg, or by 1.00 to hit ~2.2 g/kg. Those factors turn the same range into grams per day without a metric step. A 180-lb lifter lands near 130–180 g per day using that shortcut.
Food Picks That Make Hitting The Number Easy
Both animal and plant sources can build muscle. What counts is total grams per day and steady meals. Mix and match based on taste, budget, and ethics.
High-Protein Staples
- Dairy: Greek yogurt, skyr, cottage cheese, milk powders.
- Meat & Fish: Chicken breast, turkey, lean beef, tuna, salmon.
- Eggs: Whole eggs or whites blended into omelets or oats.
- Plant: Tofu, tempeh, edamame, seitan, lentils, beans.
- Powders: Whey, casein, soy, pea blends for portable hits.
Portion Math You Can Do In Your Head
- Cooked meat or fish the size of a deck of cards lands near 25–30 g.
- One cup of Greek yogurt sits around 17–20 g.
- Firm tofu, 150 g block, offers roughly 18–22 g.
- Two large eggs give about 12–13 g.
- Whey scoop labels vary; many list 20–25 g per scoop.
Vegetarian And Vegan Muscle Plan
Plant-based diets can hit the same totals. Use soy foods for complete amino profiles and mix legumes with grains across the day. A sample build could pair tofu scrambles, lentil bowls, soy-yogurt parfaits, and a pea-soy blend shake after lifting. Add nuts and seeds for extra calories on hard weeks.
Training Status, Age, And Diet Phase
Beginners: Early gains come fast. Protein near the middle of the range pairs well with steady calorie surplus and good sleep.
Intermediate To Advanced: Progress slows, and recovery needs rise. The top of the range may fit heavy blocks or when daily steps are high.
Cutting Fat: During a deficit, aim toward 2.0–2.4 g/kg to help hold lean mass. Keep resistance work in the plan and keep steps up.
Older Lifters: Appetite can dip and per-meal needs rise. Press per-meal protein toward 0.4 g/kg with easy-to-chew foods and shakes.
Evidence Backing These Numbers
Trials in trained and untrained adults show better gains with higher daily protein up to a threshold near the lower end of the stated range. Beyond that point, returns flatten for muscle size, while strength can still rise with practice and smart programming. Sports nutrition groups also endorse higher daily targets than the baseline for active people. The JISSN summary linked above is a solid primer.
Per-Meal Dose In Practice
Most people do well with 20–40 g at a meal, scaled to size. Smaller bodies sit near the low end; larger bodies near the top. After lifting, a shake or a lean meal fits the same range. Add carbs if the session ran long or legs were trained.
Protein Quality, Timing, And Carbs
Quality: Dairy proteins and soy deliver a full amino profile and mix well in meals. Blends of plant sources also work.
Timing: Spread intake across the day. Long gaps stall progress. A small snack before bed, like casein or yogurt, can help recovery.
Carbs: Lifting runs on glycogen. Add rice, pasta, oats, or fruit around sessions. That keeps training strong and leaves protein for building.
Label Reading Tips
- Check serving size: Powder labels vary. Match the grams on the label to your per-meal target.
- Scan ingredients: Whey isolate digests faster than blends. Soy and pea blends suit plant-based lifters.
- Watch sodium and sweeteners: Some shakes run salty or extra sweet. Pick what sits well in your stomach.
Budget And Prep Shortcuts
- Buy chicken thighs, eggs, and beans in bulk. Batch-cook trays on one day.
- Pick one go-to breakfast, one easy lunch bowl, and one fast dinner. Repeat on busy weeks.
- Keep shelf-stable backups: tuna pouches, milk powder, and lentil pasta.
- Blend oats into shakes for cheap carbs, then add fruit for flavor.
Common Pitfalls To Avoid
- All protein at dinner: Spreading meals beats one giant hit.
- Tiny meals: Meals that miss the per-meal dose can blunt gains.
- Low-calorie days: Hard training with too few calories drags recovery.
- Fear of carbs: Carbs help hard sets; they do not block muscle gain.
- No plan on rest days: Keep protein steady even when you do not lift.
Convert Targets Into Per-Meal Hits
Pick a per-meal target using 0.3 g/kg and match it to your schedule. The table below shows easy numbers you can apply today.
| Body Weight (kg) | Per Meal (0.3 g/kg) | Meals/Day × Grams |
|---|---|---|
| 50 | 15 g | 4 × 15 g = 60 g |
| 60 | 18 g | 4 × 18 g = 72 g |
| 70 | 21 g | 5 × 21 g = 105 g |
| 80 | 24 g | 5 × 24 g = 120 g |
| 90 | 27 g | 5 × 27 g = 135 g |
| 100 | 30 g | 5 × 30 g = 150 g |
Worked Cases
Case 1: 60 kg Novice On A Lean Bulk
Daily window: 96–132 g. Split across four meals.
- Breakfast: Oats with milk powder and banana (~25 g).
- Lunch: Tuna sandwich with extra eggs (~30 g).
- Snack: Skyr cup with nuts (~20 g).
- Dinner: Rice, beans, and chicken thigh (~30–35 g).
Case 2: 85 kg Lifter In A Mild Deficit
Daily window: 136–187 g. Push per-meal doses higher. Keep fiber and fluids high for fullness.

- Lunch: Turkey bowl with quinoa (~35–40 g).
- Snack: Whey shake with fruit (~25–30 g).
- Dinner: Lean beef with potatoes and salad (~40–50 g).
Supplements: When They Help
Whole foods can cover the plan. Powders are tools for tight schedules or lower appetites. Whey mixes fast and suits the post-lift window. Casein digests slower and suits an evening snack. Soy and pea blends serve plant-based diets well.
Safety, Health, And Special Cases
Healthy kidneys handle the ranges listed here when calories and fluids are adequate. People with kidney disease or other medical conditions need a doctor-guided plan. Pregnant and lactating lifters have separate needs shaped by stage and body size. Teens also sit in a different bracket. When in doubt, ask a registered dietitian.
How To Adjust Over Time
Track training, weight trend, and waist. If scale weight rises faster than planned, trim calories or pull protein toward the lower end. If strength stalls and appetite is fine, inch protein up by 10–20 g per day and watch the next two weeks. Repeat in small steps, and keep sleep steady.
Takeaway You Can Apply Today
Set a daily window between 1.6 and 2.2 g/kg. Hit 0.25–0.40 g/kg per meal across 3–5 meals. Add carbs around training. Use the tables and cases above to plug in your numbers and build meals you enjoy. Stay patient and lift hard.
