Adults need ~0.8–0.83 g protein per kilogram daily; many active or older adults do well in the 1.0–2.0 g/kg range.
If you want protein targets that match your size, the cleanest way is to set grams per kilogram. That gives a fair starting point for nearly everyone, then you nudge the number up or down based on activity, age, and goals.
Protein Per Kilogram Body Weight: Daily Ranges That Work
Two long-standing reference points anchor this topic. General health guidance pegs intake for adults at about 0.8–0.83 g/kg/day. Sports nutrition guidance places most training goals in the 1.2–2.0 g/kg/day window. Those bookends let you set a precise number without guesswork.
How To Calculate Your Daily Target
Take your body mass in kilograms and multiply by the target factor. If you track in pounds, divide by 2.2 first. A 70 kg person aiming for 1.2 g/kg lands at 84 g per day. Keep the math simple and stick to a single number for a week or two before tweaking.
Quick Protein Targets By Body Size
The table below gives fast lookups for common weights using three widely used daily settings: a baseline (0.8 g/kg), a moderate target (1.2 g/kg), and a higher training or appetite-control target (1.6 g/kg). Pick the column that matches your context.
| Body Mass (kg) | Baseline 0.8 g/kg | Moderate 1.2 g/kg |
|---|---|---|
| 50 | 40 g/day | 60 g/day |
| 55 | 44 g/day | 66 g/day |
| 60 | 48 g/day | 72 g/day |
| 65 | 52 g/day | 78 g/day |
| 70 | 56 g/day | 84 g/day |
| 75 | 60 g/day | 90 g/day |
| 80 | 64 g/day | 96 g/day |
| 85 | 68 g/day | 102 g/day |
| 90 | 72 g/day | 108 g/day |
| 95 | 76 g/day | 114 g/day |
| 100 | 80 g/day | 120 g/day |
Where These Numbers Come From
Baseline values trace back to international and national panels that set dietary reference values using nitrogen balance and other methods. In Europe, the scientific panel behind the protein PRI of 0.83 g/kg explains how that level covers nearly all healthy adults. The U.S. and Canada use a similar concept at 0.8 g/kg based on the DRIs from the National Academies. For training goals, the sports nutrition position stand supports 1.4–2.0 g/kg for most exercising individuals, with per-meal guidance as well.
Pick The Right Band For Your Goal
Use the band that matches how you live right now. If activity or recovery needs change, shift bands instead of forcing a one-size target year-round.
If You’re Mostly Sedentary
Start near 0.8–0.9 g/kg/day. That level covers routine turnover in healthy adults. You can edge up toward 1.0 g/kg if your appetite is steady and you like the way you feel across the day.
If You Lift Or Do Intense Training
Set intake in the 1.4–2.0 g/kg/day lane. That span supports muscle repair and strength gains when paired with smart programming. Big weeks or energy restriction phases can justify the upper half of the band.
If You’re Chasing Fat Loss
Protein helps hold lean mass while cutting calories. A practical lane is 1.6–2.0 g/kg/day, along with steady resistance work. If hunger rides high, nudge toward the top of the span for a while.
If You’re An Older Adult
Age raises the “signal” needed to build and preserve muscle. Many groups recommend 1.0–1.2 g/kg/day for healthy aging, with 1.2–1.5 g/kg/day used when strength, mobility, or recovery need a boost. Keep meals protein-forward and include resistance exercise for best results.
If You’re Pregnant Or Breastfeeding
Needs rise compared with non-pregnant adults. Across guidance, a common target is near 1.1 g/kg/day later in pregnancy, with trimester-specific adds in some systems. Work with your care team to set an exact number that fits your weight pattern and appetite.
Turn Daily Grams Into Easy Meals
Hitting a daily total is easier when you split the load across the day. A simple pattern is three to four “anchor” servings spaced by 3–5 hours. Many athletes use a per-meal rule of thumb near 0.25 g/kg from high-quality protein. That sits well with the sports position stand and covers leucine needs in most meals built around meat, dairy, or soy.
Sample Day At 70 kg
- Breakfast: ~18 g (yogurt and oats or tofu scramble)
- Lunch: ~20–25 g (beans and rice with cheese, or chicken wrap)
- Snack: ~15–20 g (milk and fruit, edamame, or a shake)
- Dinner: ~25–35 g (fish with potatoes, lentil curry, or tempeh stir-fry)
That layout lands you in the 80–95 g zone without heroic effort. Swap items, not totals, and you’ll stay on track.
Protein Sources That Make Hitting Targets Simple
Build plates around foods that deliver plenty of protein for the calories and fit your taste. Here’s a quick guide to common picks with rounded values. Mix plant and animal sources across the week for diversity.
Go-To Foods And Typical Protein
- Chicken breast, cooked: ~30 g per 100 g
- Lean beef, cooked: ~26 g per 100 g
- Fish (salmon, tuna), cooked: ~22–25 g per 100 g
- Eggs: ~6–7 g per large egg
- Greek yogurt (200 g): ~18–20 g
- Cottage cheese (150 g): ~18–20 g
- Firm tofu (100 g): ~12–14 g
- Tempeh (100 g): ~18–20 g
- Lentils, cooked (1 cup): ~18 g
- Beans, cooked (1 cup): ~14–16 g
- Milk (250 ml): ~8 g
- Protein powder (1 scoop): ~20–25 g
Fine-Tune Your Target The Smart Way
The table below maps common life stages or goals to g/kg ranges you can act on today. It also shows the typical “why” behind each range.
| Life Stage Or Goal | Daily Protein (g/kg) | Notes |
|---|---|---|
| General Adult Health | 0.8–0.9 | Covers baseline turnover; adjust if appetite or weight trends drift. |
| Endurance Training | 1.2–1.6 | Supports repair; higher end in heavy blocks or calorie deficits. |
| Strength/Hypertrophy | 1.6–2.0 | Pairs well with progressive loads and 3–5 protein-rich meals. |
| Fat Loss With Lifting | 1.6–2.0 | Helps preserve lean mass during energy restriction. |
| Healthy Aging | 1.0–1.2 | Raise to 1.2–1.5 if strength or mobility is slipping. |
| Pregnancy | ~1.1 | Often applied in later trimesters; tailor with your care team. |
| Plant-Forward Patterns | 1.0–1.4 | Mix legumes, soy, grains, nuts; spread across the day. |
Quality, Timing, And Portion Size
Quality
High-quality proteins (dairy, eggs, soy, most animal sources) deliver ample essential amino acids. Plant-only diets still hit targets with smart combos such as beans plus grains or soy-based mains. Variety across the week wins.
Timing
Steady distribution keeps muscle protein synthesis ticking. Aim for three to four feedings with 20–40 g each, or shoot for ~0.25 g/kg per meal if you prefer precise math. A protein snack in the evening can help older lifters and anyone training in the afternoon.
Portion Size Tricks
- Keep a few fixed “anchors” in mind: 1 palm of cooked meat ≈ 25–30 g; 1 cup Greek yogurt ≈ 20 g; 1 cup cooked lentils ≈ 18 g; 1 scoop whey ≈ 20–25 g.
- Stack sides with protein too: milk in oats, beans in salads, edamame with sushi.
- Batch-cook a base (beans, chicken, tofu) to make hitting your number automatic.
Safety And Upper Bounds
For healthy adults, intakes up to about 2.0 g/kg/day sit well in the research when paired with balanced eating and normal kidney function. Trained folks often run those levels during heavy blocks without trouble. If you live with kidney disease, work with your team on a tailored plan that fits your stage and meds.
Three Simple Steps To Set Your Number
- Pick your band. Baseline, training, or aging-support band from the ranges above.
- Do the math. Body mass (kg) × target g/kg = daily grams.
- Split the total. Three to four protein-forward meals, plus an optional shake or snack.
Worked Examples So You Can Copy The Math
Case A: 60 kg Office Worker Starting Light Exercise
Use 1.0 g/kg for a gentle push: 60 × 1.0 = 60 g/day. That could look like 18 g at breakfast, 20 g at lunch, 22 g at dinner.
Case B: 80 kg Lifter In A Strength Block
Use 1.8 g/kg across a tough cycle: 80 × 1.8 = 144 g/day. Split as 35–40 g in four meals and recovery stays solid.
Case C: 70 kg Older Adult Lifting Twice A Week
Use 1.2 g/kg: 70 × 1.2 = 84 g/day. Go with three anchor meals at ~25–30 g and keep walking between sessions.
Common Pitfalls And Easy Fixes
Only One Protein-Light Meal All Day
Fix it by adding a 20–30 g snack where your day has the longest gap. Milk and fruit, cottage cheese with crackers, or hummus with eggs all work.
Hitting Total Grams But Feeling Hungry
Shift a bit of protein toward earlier meals and add produce and fiber-rich carbs to steady energy. Hunger often fades when the first two meals carry enough protein.
Training Hard But Sticking To Baseline Intake
Move up to the training band for the weeks that matter. Keep carbs around workouts so protein can focus on repair.
Why This Guidance Is Trusted
The numbers above reflect best-available consensus at two levels. Population guidance sets a baseline so most adults meet needs (see the EFSA protein values). For training and physique goals, sports scientists consolidate trial data and recommend higher intakes and per-meal dosing (see the sports nutrition position stand). Those two pieces fit together neatly: start with g/kg, then place meals to match your day.
FAQ-Free Notes On Adjustments
No two weeks look the same. Travel, illness, new programs, or appetite shifts will pull you off routine. When that happens, simplify: hold your g/kg target steady, hit three anchors, and let the rest of the plate flex. You’ll land close enough to keep muscle and recovery humming.
