Why Protein Matters

Protein is an essential macronutrient used to build and repair tissues, make enzymes, and support immune function. Your intake needs vary significantly depending on whether you are sedentary or trying to build muscle.

Calculation Formula

  1. Determine your weight in pounds (lbs).
  2. Select your multiplier based on activity (e.g., 0.8g for muscle gain).
  3. Multiply Weight × Multiplier = Daily Protein Goal.
