Daily protein intake guidelines: 0.8–2.2 g per kg body weight, adjusted for age, goals, and activity.
You came here to pin down how much protein to eat each day without guesswork. The short answer lives in a range: start at 0.8 g per kilogram of body weight if you’re healthy and not very active, and scale up to 1.2–2.2 g/kg when you train hard, aim to build or keep muscle, or you’re older and want to protect strength. Below, you’ll find exactly how to choose a target, how to split it across meals, and what a week of eating could look like with real food.
How Much Protein Per Day For Your Goal
Protein needs aren’t one-size-fits-all. Body size, training load, body-comp goals, and age change the target. A reliable base comes from the Dietary Reference Intakes, which set 0.8 g/kg/day as a baseline for healthy adults. Sports nutrition research pushes higher numbers for lifters and endurance athletes, often landing between 1.2 and 2.0+ g/kg/day. Older adults benefit from a bump to counter muscle loss, commonly 1.0–1.2 g/kg/day.
Use this rule of thumb: pick the row below that matches your current goal, then calculate your daily grams by multiplying your body weight in kilograms by the g/kg range. If you track pounds, divide by 2.2 first.
Daily Protein Targets By Body Weight
| Lifestyle/Goal | Target (g/kg) | Example At 70 kg |
|---|---|---|
| Healthy, Low Activity | 0.8 | ~56 g/day |
| General Fitness | 1.0–1.2 | ~70–84 g/day |
| Muscle Gain/Strength | 1.6–2.2 | ~112–154 g/day |
| Endurance Training | 1.2–1.6 | ~84–112 g/day |
| Fat Loss While Lifting | 1.6–2.2 | ~112–154 g/day |
| Older Adults (60+) | 1.0–1.2 | ~70–84 g/day |
| Pregnancy/Lactation* | ~1.0 + trimester adds | See notes below |
*Protein needs rise during pregnancy and lactation; trimester-based increases are typically added to the adult baseline. Follow clinician guidance based on your weight and stage.
Why These Ranges Work
Protein supplies amino acids that repair tissue, build muscle after training, and maintain enzymes and hormones. The 0.8 g/kg/day baseline covers minimum needs for nitrogen balance in healthy adults, as outlined in the Dietary Reference Intakes. Higher targets help lifters and endurance athletes recover from training stress and support favorable body composition. Position statements in sports nutrition consistently land in the 1.4–2.0 g/kg/day neighborhood for most active folks, with short periods at the top of the range used during intense blocks or while cutting body fat.
Protein Timing And Per-Meal Targets
Daily totals matter most, but spreading protein across meals improves muscle protein synthesis. Aim for 20–40 g per meal, depending on body size, with a quality source that carries enough leucine. Most adults hit the response curve with 0.25–0.4 g/kg per meal. A post-training meal or shake still helps, yet you don’t need to rush; get a solid dose within a few hours of lifting or long cardio.
Evidence You Can Check
For the baseline and ranges, see the National Academies’ chapter on protein and amino acids, which codifies the 0.8 g/kg/day baseline and the 10–35% energy window for protein (DRI protein guidance). For active populations and per-meal guidance, the International Society of Sports Nutrition summarizes targets that match the ranges above (ISSN position stand).
How To Pick Your Number (And Stick To It)
Use the low end of a range when you’re smaller, lightly active, or easing back into training. Slide upward when you carry more lean mass, you’re in a calorie deficit, or your sessions run long and hard. Keep an eye on appetite and recovery: if you’re constantly sore, dragging through workouts, or hungry between meals, a modest bump can help.
Quick Math In Pounds
If you don’t want to convert to kilograms, here’s a shortcut: multiply body weight in pounds by 0.36 for the 0.8 g/kg baseline. For a higher target, multiply by 0.54 (≈1.2 g/kg), 0.73 (≈1.6 g/kg), or 1.0 (≈2.2 g/kg). A 170-lb lifter aiming for 1.6 g/kg would land near 124 g/day (170 × 0.73).
Older Adults: Protect Muscle And Strength
Past 60, the body’s muscle-building response to a meal falls, a concept often called anabolic resistance. That’s why targets shift up to 1.0–1.2 g/kg/day for healthy older adults. Pair that intake with resistance training two to three days per week and a protein-rich breakfast to hedge against long overnight gaps.
Pregnancy And Lactation
Protein needs rise with fetal growth and milk production. Many regional guidelines add trimester-specific grams per day on top of the adult baseline and keep a steady increase through lactation. Work with your clinician or dietitian to tailor the number based on pre-pregnancy weight, stage, and appetite cues.
Protein Quality: Animal, Plant, Or A Mix
Animal sources generally deliver more leucine per gram and a full essential amino acid profile. That makes it easy to hit per-meal thresholds with lean meat, poultry, fish, eggs, yogurt, and milk. Plant-forward eaters can hit the same targets with smart combinations: tofu or tempeh, soy milk, lentils, beans, peas, whole-grain breads, and seeds. Mix sources across the day and you’ll cover the amino acid bases.
Per-Meal Wins You Can Repeat
- Greek yogurt (200 g) + berries + granola: ~20–25 g
- Omelet with 3 eggs + veg + toast: ~18–24 g
- Lentil bowl (1 cup cooked) with quinoa: ~20–24 g
- Chicken or tofu stir-fry (3–4 oz cooked): ~21–28 g
- Milk or soy milk (12–16 oz) with a banana: ~12–20 g
How To Distribute Protein Through The Day
Three to five eating windows work well for most people. Match protein to your training when you can. If you lift in the morning, anchor breakfast with a solid portion. If you train in the evening, leave room for a protein-forward dinner or snack.
Protein In Common Foods (Typical Serving)
| Food | Serving | Protein (g) |
|---|---|---|
| Chicken Breast, Cooked | 3 oz (85 g) | ~26–28 |
| Lean Beef, Cooked | 3 oz (85 g) | ~22–26 |
| Salmon, Cooked | 3 oz (85 g) | ~21–23 |
| Eggs | 2 large | ~12 |
| Greek Yogurt, Plain | ¾–1 cup (170–200 g) | ~15–20 |
| Milk Or Soy Milk | 12 oz (355 ml) | ~12–15 |
| Tofu, Firm | 3 oz (85 g) | ~8–12 |
| Tempeh | 3 oz (85 g) | ~15–18 |
| Lentils, Cooked | 1 cup (198 g) | ~18 |
| Chickpeas, Cooked | 1 cup (164 g) | ~14–15 |
| Peanut Butter | 2 Tbsp (32 g) | ~7 |
| Mixed Nuts | 1 oz (28 g) | ~4–6 |
| Cottage Cheese, Low-Fat | ½ cup (113 g) | ~12–14 |
Food values vary by brand and prep method; numbers above follow common clinical handouts and nutrition databases.

Cutting Fat Without Losing Muscle
When calories drop, lean mass can slip. A higher protein target helps you hold the line while you lean out. Match it with resistance training and enough sleep. Keep carbs around workouts for performance, and fill the plate with colorful produce for fiber and micronutrients. If appetite is a challenge, go for leaner cuts, strained dairy, soy foods, and light protein shakes to hit numbers without blowing the calorie budget.
Hydration, Kidneys, And Safety Notes
Healthy kidneys handle higher protein within the ranges above. If you live with kidney disease or another medical condition, talk with your care team before raising intake. Drink water to match your training and climate. Include calcium-rich foods and produce to balance a higher-protein pattern.
Supplements: When A Shake Makes Sense
Whole foods can cover every gram you need. A ready-to-mix option helps when convenience matters or appetite runs low. Whey, casein, and soy powders are complete proteins with good leucine content. Pea and rice blends can match that profile with the right mix. Treat shakes like food: check labels, choose options with simple ingredient lists, and pair them with fruit or grains if you need extra carbs around training.
How To Adjust Over Time
Keep your chosen number for two to four weeks. Track how you feel, train, and recover. If lifts stall or you feel rundown, edge upward by 10–15 g/day. If you’re stuffed or gaining unwanted weight, trim by the same amount and watch the next two weeks. Your best number is the one you can follow on busy days as well as perfect ones.
Frequently Missed Details
Breakfast Gap
Many folks eat a low-protein breakfast and land at dinner with a big deficit. Front-loading the day with 25–35 g makes the rest easy.
Per-Meal Thresholds
Hitting a muscle-building response takes enough leucine and total protein. If your meals hover at 10–15 g, bump portions or add a small side, like a yogurt cup, milk, or a scoop of tofu.
Plant-Forward Planning
Build meals around soy, beans, lentils, and grains. Add seeds or nuts to raise totals. A tofu scramble at breakfast, lentils at lunch, and a tempeh dinner can match any meat-based day gram-for-gram.
Putting It All Together
Pick a g/kg range based on goal and activity. Multiply by body weight to set a daily number. Split that number over three to five meals. Choose foods you enjoy and can prep quickly. Review your progress every few weeks and nudge the target up or down by small amounts until energy, training, and hunger line up.
