Practical Examples of Using the Macros Calculator

Example 1: Bulking Phase for Muscle Gain

John is a 28-year-old male weighing 75 kg, standing 178 cm tall, moderately active, and wants to bulk. By using the calculator, he discovers:

  • BMR: 1,760 kcal
  • TDEE (Adjusted for Bulking): 2,024 kcal
  • Protein: 165 g
  • Carbs: 250 g
  • Fats: 56 g

These numbers allow John to structure meals that optimize muscle growth without excessive fat gain. He can now track his food intake and ensure he’s consuming enough calories and macronutrients to support his workouts.

Example 2: Cutting Phase to Lose Fat

Sarah is a 32-year-old female, 65 kg, 165 cm, lightly active, and wants to lose fat. The calculator provides:

  • BMR: 1,410 kcal
  • TDEE (Adjusted for Cutting): 1,200 kcal
  • Protein: 143 g
  • Carbs: 110 g
  • Fats: 33 g

With this guidance, Sarah can create a daily meal plan that promotes fat loss while maintaining muscle mass. By adhering to these targets, she avoids extreme calorie restriction and ensures balanced nutrition.
