For muscle gain, most lifters do best with 1.6–2.2 g protein per kg body weight per day, split across 3–5 meals.
Muscle tissue grows when training and nutrition line up. Protein feeds that process with amino acids that turn workouts into new fibers. The right daily target sets your base, and smart meal timing helps you use it well. This guide gives simple numbers, food ideas, and a plan you can start today.
Daily Protein Targets For Building Muscle
Research links a clear intake range with steady strength and size gains. Across multiple trials, intakes around the midpoint of this range drive much of the growth seen with resistance training. Going far past the top end brings little added return for trained adults.
| Body Weight | Daily Protein Range | Notes |
|---|---|---|
| 50 kg (110 lb) | 80–110 g | Use the lower end on light training weeks |
| 60 kg (132 lb) | 95–130 g | Shift up when volume or intensity rises |
| 70 kg (154 lb) | 110–155 g | Common target for many beginners |
| 80 kg (176 lb) | 130–175 g | Plan 30–40 g per meal across 4 meals |
| 90 kg (198 lb) | 145–200 g | Higher end suits hard training blocks |
| 100 kg (220 lb) | 160–220 g | Spread over 4–5 feedings for comfort |
That range reflects a daily target of about 0.7–1.0 g per pound (1.6–2.2 g/kg). Most people can stay near the middle on normal training weeks, then push toward the top during heavy blocks or when dieting and trying to keep lean mass.
Why This Range Works
Resistance exercise and protein work together. Lifting triggers a spike in muscle protein turnover, and amino acids supply the building blocks. Studies show that once daily intake reaches a solid threshold, extra grams add little muscle. The sweet spot above keeps you covered without bloat or needless cost.
What About The RDA?
The general guideline of 0.8 g/kg covers basic maintenance in sedentary adults. That figure was set to meet minimum needs, not growth on a lifting plan. Athletes and regular lifters usually need more to drive recovery and new tissue.
Per-Meal Targets And Timing
Daily totals matter most. Still, meal size and spacing help you use that total. A simple rule works well: aim for 0.4–0.55 g/kg at each main meal, eaten every three to four hours. Across the day this lands you inside the range above with room for a shake or snack.
Quick Math You Can Use
If you weigh 70 kg, 0.4 g/kg is about 28 g per meal. Four meals at that size deliver 112 g for the day. Push meals to the 0.5–0.55 g/kg mark during a hard block or when dieting.
Post-Workout Window, Without Hype
Protein before or after training both works. The training effect lasts for many hours, so a meal in the two-hour window around your session fits well. A serving that hits the per-meal rule above is enough.
Best Protein Sources For Hypertrophy
Any pattern can work: omnivorous, vegetarian, or vegan. The goal is enough total protein with a solid spread of essential amino acids. Mix whole foods you like with convenience options when life gets busy.
Whole Foods That Pack A Punch
- Chicken breast, turkey, lean beef
- Eggs and egg whites
- Greek yogurt, skyr, cottage cheese, milk
- Tofu, tempeh, edamame, seitan
- Lentils, beans, chickpeas, split peas
- Firm fish like tuna or salmon
Shakes And Bars
Whey, casein, soy, and pea blends all help you hit your meals when cooking is not an option. Pick one that sits well and matches your budget. A 20–40 g serving usually lands near the per-meal target for most adults.
Sample Day: Hitting Your Number
Here is a simple day for a 75 kg lifter with a target near the middle of the range. Adjust portions to fit your size and appetite.
Training Day Outline
- Breakfast: 2 eggs, egg-white scramble, oats with milk, berries (30–35 g)
- Lunch: Chicken wrap with Greek yogurt sauce, side beans (35–40 g)
- Pre-Lift Snack: Skyr with banana or soy yogurt with granola (20–25 g)
- Post-Lift: Whey or soy shake; toast with peanut butter (30–35 g)
- Dinner: Salmon, rice, roasted veg, or tofu stir-fry (35–40 g)
Adjusting Intake For Goals
Your number is not static. Shift it with your goal, training load, and calorie intake.
When You Are Cutting
Lean mass is at risk when calories drop. Aim toward the top of the range, keep meal size steady, and bias choices toward higher-quality sources per calorie. Extra vegetables and fruit add volume so meals still feel satisfying.
When You Are Bulking
More calories make protein easier to hit. You still do not need to overshoot. Keep intake inside the range, direct extra calories to carbs and fats you enjoy, and keep lifting quality high.
When You Are New To Lifting
Beginners respond well. Start near the middle of the range and build steady habits first: four meals, each with a palm-sized serving of protein, plus plants and grains you like. Track progress in the gym and adjust only if strength stalls or body weight drops fast.
Common Myths, Cleared Up
“Extra Protein Damages Kidneys”
In healthy people with normal lab values, intakes in the range listed here are widely used in trials without harm. Anyone with kidney concerns should work with a clinician.
“Your Body Can Only Use 30 Grams”
Per-meal needs scale with body size. Smaller eaters may land near 20–30 g. Larger athletes often need 35–50 g to hit 0.4–0.55 g/kg per meal. The target is a range, not a hard cap.
“You Must Chug A Shake Right After The Last Rep”
You do not need panic timing. Eat a normal meal before or after and you are set. Keep spacing steady across the day and train hard.
Practical Meal Size Guide
Use this as a fast planner for your size. Pick a row, then split the number across 3–5 meals that match your schedule.
| Body Weight | Per-Meal Target | Easy Ways To Hit It |
|---|---|---|
| 55–65 kg | 22–30 g | 1 cup skyr; or tofu bowl; or 1 can tuna |
| 66–80 kg | 26–40 g | Chicken wrap; or lentil curry; or 2 eggs + yogurt |
| 81–95 kg | 32–45 g | Beef stir-fry; or tempeh noodles; or salmon plate |
| 96–110 kg | 38–55 g | Large tofu scramble; or steak burrito; or shake + snack |
How To Build Your Own Plan
Step 1: Pick Your Daily Number
Multiply body weight in kilograms by 1.6 for a base. Nudge toward 2.0–2.2 during heavier blocks, when cutting, or if you train twice in a day.
Step 2: Set Meals
Pick three to five eating windows that fit your day. Place one near training and two to four others spaced out. Many people like breakfast, lunch, mid-afternoon, dinner, and a small evening snack.
Step 3: Build Plates
Anchor each plate with a protein pick, then add carbs and fats you enjoy. Whole grains, potatoes, fruit, nuts, seeds, and oils round out energy needs for hard training.
Step 4: Check Results
Track key lifts, weekly body weight, sleep, and fullness. If strength climbs and your waist holds steady, you are on track. If energy lags or you lose weight fast, raise carbs first, then add a bit of protein if meals feel small.
Special Cases
Plant-Based Athletes
Meeting the same total is doable with soy foods, legumes, grains, and seeds. Mix sources across the day and use a soy or pea blend shake if appetite is low. Season well so meals stay fun to eat.
Masters Lifters
With age, the signal to build muscle can be less sensitive. Keep daily intake near the upper end and make sure each meal is a solid serving. Train with effort and include some power work if joints allow.
Busy Schedules
Keep shelf-stable options in reach: canned fish, long-life milk, ready-to-drink shakes, roasted chickpeas, and high-protein yogurts. A backup plan turns missed cooking time into a quick meal, not a missed target.

Bottom Line And Quick Start
Pick a daily target inside 1.6–2.2 g/kg. Split it across four meals. Place one near training. Fill plates with foods you enjoy and can repeat. Lift with effort, sleep well, and give the plan a few weeks. Small steps stack into new muscle.
