Formula Used
The calculator employs the Mifflin-St Jeor Equation: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + s (s is +5 for males and -161 for females). It then adjusts your Total Daily Energy Expenditure (TDEE) based on activity level and applies a caloric deficit for weight loss, with a macronutrient distribution of 40% carbohydrates, 30% protein, and 30% fat.
Examples
- 25-year-old female, 65kg, 170cm, sedentary: Needs about 1500 calories/day. Macros: 150g carbs, 113g protein, 50g fat.
- 30-year-old male, 80kg, 180cm, moderately active: Requires approximately 2500 calories/day. Macros: 250g carbs, 188g protein, 83g fat.
- 22-year-old female, 55kg, 160cm, lightly active: Should consume around 1800 calories/day. Macros: 180g carbs, 135g protein, 60g fat.
