Protein Basics: How Much Do You Actually Need?
Protein is the most talked-about nutrient in fitness and the most misunderstood. It is not magic, and you do not need to live on shakes. But most people who train do under-eat it, and the fix is simpler than the supplement industry suggests.
The number
If you strength train, a solid target is 1.6 grams of protein per kilogram of bodyweight per day. At 80 kg, that is about 130 g. At 60 kg, about 95 g. More than that offers little extra benefit for most people; less than about 1.2 g/kg and you are likely leaving muscle and recovery on the table. Sedentary adults need less — around 0.8–1.0 g/kg — but if you are reading this site, you are probably training.
Spread it across the day
Your body uses protein best in doses of roughly 25–40 g per meal. Four meals with 30 g each beats one giant protein dinner. Practical anchors: eggs at breakfast (about 6 g each), Greek yogurt or cottage cheese as a snack (15–20 g per serving), a palm-and-a-half of meat or fish at lunch and dinner (30–40 g each).
Do you need a shake?
No — but it is convenient. A scoop of whey is simply portable protein, not a muscle potion. If you can hit your target with food, skip it. If you are busy, a shake between meals is the easiest way to close a 25 g gap. Choose one with minimal ingredients and no need for the one with the fanciest label.
The myths
"High protein damages your kidneys." In healthy people, the evidence does not support this. If you have kidney disease, talk to your doctor — that is a different situation.
"You must eat protein within 30 minutes of training." The "anabolic window" is mostly a myth. Total daily intake matters far more than timing.
"Plant protein doesn't count." It counts. You just need slightly more of it and some variety — beans, lentils, tofu, tempeh and whole grains together cover your amino acids.
Protein works alongside training and recovery. Pair this with the strength basics and the sleep guide, and the fundamentals are covered.
