Practical Example

Let’s say Sarah weighs 160 lbs, has a body fat of 25%, and is moderately active. Using the calculator:

  • Lean mass = 160 × (1 – 0.25) = 120 lbs
  • Calories = 120 × 14 × 1.55 ≈ 2,604 kcal
  • Protein = 120 × 2.2 ≈ 264 g
  • Fat = 25% of calories ÷ 9 = 72 g
  • Carbs = Remaining calories ÷ 4 = 1,404 ÷ 4 ≈ 351 g

Sarah now has clear daily macro targets: 264g protein, 351g carbs, 72g fat, and 2,604 calories. She can plan meals around these numbers for optimal weight loss.
