The protein target for weight gain is 1.6–2.2 g per kg daily, spread across meals with a steady calorie surplus.
You came here to set a clear protein goal for lean mass. This guide gives a no-nonsense target, shows how to calculate grams for your body, and turns that number into meals you can actually eat. You’ll also see how carbs and fats fit the plan, how to split protein through the day, and what to do when the scale won’t budge.
Why Protein Drives Lean Gain
Muscle grows when daily intake beats daily breakdown. Resistance training spikes muscle protein synthesis, and protein feeds that process. Research bodies that track sport nutrition say a daily intake in the 1.6–2.2 g per kg range suits most lifters who want size. The range covers light days, hard weeks, and individual variation.
Quick Targets By Body Weight
Find your body weight in the first column, then hit a number in the right column each day. The range reflects the spread that research groups endorse for people chasing muscle.
| Body Weight | Daily Protein (g) | Notes |
|---|---|---|
| 50 kg (110 lb) | 80–110 | Lower end for rest days |
| 60 kg (132 lb) | 96–132 | Middle suits mixed training |
| 70 kg (154 lb) | 112–154 | Push higher in heavy blocks |
| 80 kg (176 lb) | 128–176 | Watch fiber so meals fit |
| 90 kg (198 lb) | 144–198 | Use shakes to fill gaps |
| 100 kg (220 lb) | 160–220 | Pre-prep high-protein snacks |
Set Your Exact Number
Pick a point in the range that fits training load, appetite, and recovery. A simple rule that rarely misses: start at 1.8 g per kg. If lifts feel flat or you stay sore, move toward 2.0–2.2. If you’re smaller framed or new to lifting, 1.6–1.7 may feel easier while you build habits.
Step-By-Step Math
- Convert weight: 1 kg = 2.205 lb.
- Choose a multiplier: 1.6–2.2 g per kg.
- Multiply body weight in kg by your chosen number.
Sample: 75 kg × 1.8 g = 135 g per day.
Close Variant: Protein Needed To Gain Healthy Mass — Practical Ranges
Ranges exist for good reason. Training stress, sleep, age, and calorie intake all shift needs. Younger lifters often thrive around 0.25–0.40 g per kg per meal. Older lifters do better near the upper end per meal due to lower sensitivity to amino acids.
Pair Protein With A Calorie Surplus
Protein alone won’t move the scale. Add a steady surplus of 250–500 calories per day above maintenance while you train hard three to four days each week. Track body weight two to three times per week, right after waking, and aim for 0.25–0.5 kg per week. If weight stalls for 10–14 days, bump daily calories by 150–200.
Meal Distribution That Works
Split intake across three to five meals. Per meal, aim for about 0.35–0.45 g per kg. That dose hits the amino acid threshold that flips muscle building on, then you repeat the signal later in the day. A pre-bed dairy snack can help you reach the day’s total without huge dinner portions.
Per-Meal Cheat Sheet
Use this table to plan portions. Pick the row that matches your weight and the column with your meal count.
| Body Weight | 3 Meals | 4 Meals |
|---|---|---|
| 60 kg | 20–27 g each | 15–22 g each |
| 75 kg | 26–34 g each | 20–28 g each |
| 90 kg | 32–40 g each | 25–32 g each |
| 105 kg | 37–47 g each | 29–39 g each |
Pick Foods That Make Hitting Targets Easy
High-protein foods shrink the portion sizes you need and keep meals tidy. Lean meats, eggs, dairy, soy, and legumes lead the pack. Pair them with carb-dense sides to drive the surplus.
Handy Portion Math
- Cooked chicken breast: about 31 g per 100 g.
- Greek yogurt (2%): about 10 g per 100 g.
- Firm tofu: about 8 g per 100 g.
- Cooked lentils: about 9 g per 100 g.
- Canned tuna: about 23–25 g per 100 g.
- Cottage cheese (low-fat): about 11–12 g per 100 g.
Carbs And Fats Still Matter
Carbs fuel hard sessions and refill glycogen. Fats carry flavor and calories that help you reach the surplus without giant plates of food. A simple macro split that plays nice with the protein plan: keep protein fixed, then set carbs and fats to taste while you meet your calorie goal. Many lifters land near 40–55% of calories from carbs and 20–35% from fats.
Timing Tricks That Help
- Post-training meal within two hours. Pack real food or a shake so you don’t miss the window.
- Even spacing. Hit a protein dose every three to five hours while awake.
- Pre-sleep dairy. Casein-rich snacks help reach totals and play nice with overnight recovery.
How To Build A Day Of Eating
Here’s a sample day for a 75 kg lifter on 1.8 g per kg (135 g daily), split into four feeds with a small surplus.
Breakfast
Eggs on whole-grain toast with fruit. Two eggs plus extra whites, Greek yogurt on the side.
~35 g protein, balanced carbs and fats.
Lunch
Chicken, rice, and mixed veg with olive oil. Add beans if you need more calories.
~35 g protein.
Snack
Greek yogurt parfait with oats and berries. Toss in nuts if the surplus is short.
~25 g protein.
Dinner
Salmon, potatoes, and salad with dressing.
~40 g protein.
Plant-Forward Mass Gain
Building size on plants works well with a bit of planning. Mix soy foods, legumes, grains, and seeds across the day. Use higher-protein picks like tofu, tempeh, seitan, edamame, lentils, chickpeas, and soy milk. A soy shake or a pea-rice blend makes it easy to top off the day.
What The Research Groups Say
Sport nutrition bodies summarize a wide span of studies and land in the same zone: daily intake around 1.6–2.2 g per kg covers most lifters aiming for lean mass, and spreading doses across the day helps. You can read one such statement from the International Society of Sports Nutrition. Health policy panels set a lower baseline for general adults at 0.8 g per kg; that level meets basic needs, not muscle gain. For the formal reference, see the National Academies’ chapter on Dietary Reference Intakes for protein.
Common Roadblocks And Fixes
Appetite Isn’t There
Use liquids and softer foods. Smoothies with milk, yogurt, oats, and whey go down fast. Soups over rice with shredded meat or tofu help too.
Meal Prep Takes Too Long
Batch-cook one protein twice a week. Bake a tray of chicken thighs or press two blocks of tofu on Sunday and Wednesday. Freeze single-serve portions.
Scale Won’t Move
Track three morning weigh-ins per week and take the average. If the trend stalls for two weeks, raise intake by 150–200 calories per day and hold that for 10 days before judging again. Keep training logs to spot changes in volume or sleep that might slow progress.
Digestive Upset
Space fiber through the day and add more water. Swap some beans for dairy or fish, or use lactose-free dairy if needed.
Safe Upper Limits
Healthy lifters with normal kidney function do well in the ranges above. Research in trained folks using intakes above 2 g per kg has not shown harm when total calories and micronutrients stay balanced. If you have a medical condition, speak with your clinician before large changes.
Supplement Or Food?
Shakes are handy, not magic. Whole foods bring iron, zinc, calcium, omega-3s, fiber, and more. Use powders to fill a gap when meals fall short or when a work day gets hectic. A single scoop pairs well with fruit and a bagel to make a quick post-gym meal.
Simple Tracking That Doesn’t Take Over Your Life
Pick one method and keep it light. You can log grams for a week to learn portions, then switch to plate-based habits. Another route is to pre-build two high-protein breakfasts, two lunches, and two dinners, and rotate them. Keep fruit and dairy at home and nuts at work so snacks are sorted.
Protein Density Snapshot
These values help you eyeball portions during busy weeks. Exact numbers vary by brand and cooking method, so check labels when you can.
| Food (Per 100 g) | Protein (g) | Tip |
|---|---|---|
| Chicken breast, cooked | ~31 | Meal-prep friendly |
| Salmon, cooked | ~22 | Adds omega-3s |
| Lean beef, cooked | ~26 | Iron-rich |
| Greek yogurt, 2% | ~10 | Great with fruit |
| Cottage cheese, low-fat | ~11–12 | Easy pre-bed |
| Firm tofu | ~8 | Press for texture |
| Tempeh | ~19 | Dense and nutty |
| Edamame, cooked | ~11 | Snack or side |
| Lentils, cooked | ~9 | Works in soups |
| Chickpeas, cooked | ~9 | Blend into dips |
| Peanut butter | ~25 | Calorie booster |
| Whey isolate powder | ~85 per 100 g | Check scoop size |
Week-By-Week Adjustments
Run your plan for three weeks, then review. If fat gain is racing ahead of strength, trim 100–150 calories from fats or carbs while holding protein steady. If lifts rise and waist stays steady but weight is flat, add a small snack with 15–20 g protein and 200–250 calories.
Checklist You Can Screenshot
- Pick 1.6–2.2 g per kg for daily intake.
- Split into 3–5 meals; target ~0.35–0.45 g per kg per meal.
- Hold a 250–500 calorie surplus and lift 3–4 days weekly.
- Use dense foods and simple prep to stay on track.
- Review every three weeks; adjust calories by small steps.
Method Notes And Limits
Numbers in this guide match ranges from sport nutrition groups and health policy panels. The higher ranges serve trained folks seeking lean mass with structured lifting. The lower baseline suits general adults meeting basic needs, not size goals. If you have kidney disease, liver disease, or another medical issue, work with your care team for a tailored plan.
