70 kg ⇒ about 112 g protein

How it works

This formula estimates a daily protein intake of about 1.6 grams for every kilogram of body weight. That amount is commonly used in sports nutrition because protein supplies the amino acids needed to repair muscle damage from training and to support muscle growth when combined with enough calories and resistance exercise. It is a practical target rather than an exact rule, so individual needs can vary with age, training volume, and overall diet.

When to use it

Use this when planning a muscle-building diet, especially if you do regular strength training and want a simple daily protein target. It is also helpful when comparing protein content across meals to check whether your total intake is likely high enough.

Worked example, step by step

Suppose a person weighs 82 kg. P = 1.6 × m P = 1.6 × 82 P = 131.2 So the daily protein target is about 131 g of protein per day.

Common mistakes to avoid

  • Using pounds instead of kilograms in the formula
  • Forgetting that this is a daily total, not the amount per meal
  • Treating the result as exact instead of an estimate that can be adjusted for individual needs

Did You Know?

Studies show muscle gain plateaus near 1.6 g/kg per day — eating far more protein brings little extra benefit.
