Practical Example: Calculating Daily Macros

Let’s say John is 30 years old, weighs 75 kg, stands 180 cm tall, and is moderately active.

1. Input details:
   • Weight: 75 kg
   • Height: 180 cm
   • Age: 30
   • Gender: Male
   • Activity Level: Moderately Active
2. Calculate Calories & Macros:
   • Basal Metabolic Rate (BMR) for male: 10 × 75 + 6.25 × 180 − 5 × 30 + 5 = 1,755 kcal
   • Adjusted for activity (moderate = 1.55): 1,755 × 1.55 ≈ 2,721 kcal/day
   • Protein (30% of calories ÷ 4): 0.3 × 2,721 ÷ 4 ≈ 204 g
   • Fat (25% of calories ÷ 9): 0.25 × 2,721 ÷ 9 ≈ 76 g
   • Carbs (45% of calories ÷ 4): 0.45 × 2,721 ÷ 4 ≈ 306 g

John now knows his ideal daily intake: 2,721 kcal, 204 g protein, 306 g carbs, 76 g fat.
