how much protein per day to build muscle

For building muscle, most active people grow well on about 1.6–2.2 grams of protein per kilogram of body weight per day (roughly 0.7–1.0 grams per pound).

How Much Protein Per Day to Build Muscle

Quick Scoop

  • General muscle-building range: 1.6–2.2 g/kg body weight per day.
  • Everyday baseline (not focused on muscle): about 0.8 g/kg body weight per day.
  • Many lifters use a simple shortcut: around 1 g of protein per pound of target body weight as an easy upper-end estimate.
  • Going far beyond 2 g/kg long term usually doesn’t build extra muscle and may add unnecessary stress (extra calories, kidney load if you already have kidney issues).

Step 1: Pick Your Target Range

Use your training goal and intensity to choose a spot inside the 1.6–2.2 g/kg range.

  • Light or moderate training (3x per week, beginner):
    • Aim for 1.2–1.6 g/kg.
  • Serious muscle-building (4–6x per week, progressive overload, good sleep):
    • Aim for 1.6–2.0 g/kg.
  • Short, intense bulk or first 8–12 weeks of a challenging new program:
    • Up to 2.2 g/kg , especially if you’re lean and training hard.

Example:
If you weigh 75 kg and are training seriously, a good daily target is around 120–150 g protein.

Some experts also say you can set protein as 1 g per pound of your “goal” body weight , especially in gym culture, which lands you in a similar ballpark.

Step 2: Turn It Into Real Numbers

1. Convert your weight

  • In kilograms: use 1.6–2.2 × your kg body weight.
  • In pounds: use 0.7–1.0 × your lb body weight (or just “1 g per pound”).

Example (150 lb / 68 kg person):

  • Muscle-building range: 110–150 g protein per day.
  • A health system example suggests ~69–102 g/day to build muscle for 150 lb, which is the same range.

Step 3: Timing for Better Gains

You don’t have to obsess over timing, but a few habits help:

  • Spread protein across 3–5 meals so each meal has a decent dose (20–40 g for most people).
  • After lifting, aim for about 0.25–0.3 g/kg within roughly 2 hours (about 20–30 g for many people) to support muscle repair.
  • Hit your total daily target first; timing is just the finer detail.

Step 4: How Much Is “Too Much”?

Your body has a point of diminishing returns: more protein doesn’t automatically equal more muscle.

  • Above 2 g/kg per day doesn’t seem to give extra gains for most lifters.
  • Consistently very high intakes (e.g., huge surplus calories, well over 2 g/kg) can:
    • Make you gain fat more easily (extra unused calories).
* Be a concern if you already have **kidney disease** , so you’d want medical supervision.

A balanced, high-but-not-crazy zone like 1.6–2.2 g/kg is usually ideal for muscle without unnecessary risk for healthy people.

Mini Guide: What That Looks Like in Food

Rough examples of ~120–150 g protein/day :

  • 2 chicken breasts (~50–60 g total) plus a pint of milk (~20 g).
  • Add:
    • 1 cup Greek yogurt (~15–20 g),
    • 2 eggs (~12 g),
    • 1 cup lentils (~18 g),
    • Some oats and nuts (~10–15 g).

For a vegan day, you might mix soy protein, tofu, lentils, and oats to hit similar totals, as some fitness writers highlight.

How This Connects to “Latest News” and Forum Talk

  • Recent health and fitness articles in the mid‑2020s generally align around 1.6–2.2 g/kg as the max-growth zone, not the ultra-high intakes that old-school bro-science sometimes promoted.
  • Forum discussions often still quote “1 g per pound” , which fits inside that range and remains a popular, easy rule, but newer expert writeups stress that more than that is rarely necessary for most lifters.
  • Main takeaway: hit that 1.6–2.2 g/kg range, train hard, sleep well, and stay in a small calorie surplus —that combination matters more than chasing extreme protein numbers.

TL;DR:
To build muscle, aim for about 1.6–2.2 g of protein per kg of body weight per day (roughly 0.7–1.0 g per pound), spread over the day, and pair it with solid training and recovery.
