How much protein do you actually need?
Protein is the one nutrient most worth getting right if you lift. It is the raw material your body uses to repair and build muscle after training, and unlike the endless debate around carbs and fats, the science here is settled. You do not need powders, precise timing or a shaker in every hand. You need to hit a sensible daily total, most days.
This guide gives you that number, shows how to reach it from ordinary food, and clears up the myths about timing windows and 'too much' protein that make people overthink it.
The number that matters
For building muscle, a broad evidence base points to roughly 1.6 to 2.2 grams of protein per kilogram of bodyweight per day, or about 0.7 to 1 gram per pound. For most people, aiming near the middle at around 1.6 to 1.8 g/kg captures nearly all the benefit. An 80 kg person is looking at roughly 130 to 175 grams of protein a day. Going far above this range does not build extra muscle, because the returns flatten out, which makes the top of the range a ceiling worth knowing rather than a target to beat.
If you are in a calorie deficit trying to lose fat while keeping muscle, nudge toward the higher end. Protein is protective of muscle when overall energy is low, and it is the most filling of the three macronutrients, which helps with hunger. If you are older, slightly higher intakes also help offset the body's reduced efficiency at using protein with age.
Use your target bodyweight rather than a very high current one if you're carrying a lot of fat, since protein needs track lean mass and calculating off a large total can overshoot. When in doubt, a registered dietitian can set this precisely for you.
Hitting it from real food
You can reach these numbers from ordinary meals, and powder is a convenience rather than a requirement. Protein is dense in meat, poultry, fish, eggs and dairy, and available in good amounts from beans, lentils, tofu, tempeh and seitan for plant-based eaters. As rough anchors: a chicken breast is around 30 to 40 g, a can of tuna about 25 g, three eggs about 18 g, a large tub of Greek yoghurt 15 to 20 g, and a scoop of whey powder 20 to 25 g.
The practical trick is to anchor each meal around a protein source instead of treating it as a side. Build a plate that starts with the meat, fish, eggs, dairy or legumes, then add carbs and vegetables around it, and you will hit your daily total across three or four meals without tracking every gram. Plant-based eaters need a bit more variety and slightly larger portions, since plant proteins are individually less complete, which eating a range of sources across the day solves.
Timing, and the myths
The anabolic window, the idea that you must get protein in within 30 minutes of training or waste the session, has been thoroughly overstated. Your total protein across the whole day is what overwhelmingly drives muscle building, and the exact clock time of each serving is a minor detail. Spreading protein across three or four meals, each with a decent portion, is a reasonable habit mostly because it is practical and filling.
The other persistent myth is that high protein is dangerous for healthy people. For those with normal kidney function, intakes in the range above are well tolerated in the research. The important caveat: if you have kidney disease or another relevant medical condition, protein does need to be managed with professional guidance, which is exactly the kind of individual situation to raise with a doctor rather than take from an article.
You don't need protein immediately after training. A protein-containing meal within a few hours either side of your session is more than enough.
Knowing whether you actually hit it
Most people who think they eat plenty of protein fall well short when they first measure it, and the gap between feeling protein-heavy and actually hitting 1.6 g/kg is large. You do not need to weigh food forever, but logging your intake in a food-tracking app for a week or two is eye-opening and shows you which meals carry the load and which need a protein anchor added.
Durata is not a food logger. You track meals in whatever nutrition app you already use, and Durata syncs your daily calories and protein from Apple Health or Health Connect and shows them alongside your training. Your intake and your lifting sit in one place, so you can see at a glance whether your protein is landing where your target says it should. Once you have calibrated a few go-to meals that hit your number, you rarely need to track closely again, because you can repeat the meals you already know work.
Common questions
How much protein do I need to build muscle?
Roughly 1.6 to 2.2 grams per kilogram of bodyweight per day, about 0.7 to 1 g per pound. For most people around 1.6 to 1.8 g/kg captures nearly all the benefit, so an 80 kg person needs roughly 130 to 175 g a day. More than this does not build extra muscle.
Do I need protein powder?
No. Powder is a convenient way to top up, but you can hit your target entirely from food: meat, fish, eggs, dairy, and beans, lentils, tofu and other plant sources. Anchor each meal around a protein source and the daily total takes care of itself.
Is there an anabolic window after training?
Not the strict 30-minute one people worry about. Your total protein across the whole day is what matters, and eating a protein-containing meal within a few hours either side of training is plenty.
Can too much protein harm you?
For people with healthy kidneys, intakes in the muscle-building range are well tolerated in research. If you have kidney disease or another relevant condition, protein should be managed with a doctor or dietitian, since that is an individual medical question rather than a general one.
How do I know if I'm eating enough protein?
Track it in a food app for a week or two, because most people are surprised how far short they fall. Durata then syncs your daily calories and protein from Apple Health or Health Connect and shows them next to your training, so you can check your real intake against your target instead of guessing.
