How Much Protein Do You Really Need?

If you lift and you want to grow, protein is the one nutrition number worth obsessing over. Everything else — meal timing, supplement stacks, superfoods — is noise compared to hitting your daily protein target. The good news: the target is simpler than the internet makes it sound.

The number: 1.6 to 2.2 g per kg

For people who train with weights, the research keeps landing in the same range: roughly 1.6 to 2.2 grams of protein per kilogram of body weight per day. An 80 kg lifter needs about 130 to 175 grams. Going higher is not dangerous for healthy people, but the extra grams stop buying you extra muscle. Going much lower leaves gains on the table, especially in a calorie deficit.

Notice what that range is not. It is not per meal. It is not per shake. It is a daily total. Hit the total and the details mostly sort themselves out.

Does timing matter?

Less than you think. Spreading protein across three to five meals is slightly better than cramming it into one, because each protein feed gives muscle protein synthesis a fresh push. But the difference between three meals and five is small. The difference between 90 grams a day and 160 grams a day is large. Fix the total first.

Two cases justify the top of the range. In a fat-loss phase, protein closer to 2.2 g per kg helps you hold on to muscle while calories drop, and it keeps you fuller between meals — the cheapest appetite control there is. Lifters past their forties also do well aiming higher, because aging muscle responds less strongly to each individual protein feed.

Where to get it

Food first. Powders are convenient, not magic. Solid defaults:

Chicken, turkey, lean beef and pork — 25 to 30 g per portion
Eggs — about 6 to 7 g each, cheap and versatile
Greek yogurt and skyr — 15 to 20 g per pot
Tuna and other fish — 20 to 25 g per can or fillet
Lentils, beans, tofu and tempeh for plant-based lifters
Whey or plant protein powder to close the gap on busy days

Quick check: weigh yourself in kg, multiply by 1.6. If your average day lands below that number, that is your first fix — before any supplement, program tweak or new split.

Make it measurable

You cannot manage what you never measure. Track protein loosely for two normal weeks and you will know your baseline for good. If weighing food feels like a chore, describe your meals in plain words in Gymia and the AI meal logging estimates protein for you, then the Daily Pulse ring shows how close you are to target.
