Calorie Formula (BMR Concept)

Basal Metabolic Rate (BMR) is the number of calories your body needs at rest to maintain basic physiological functions. Our calculator uses the Harris-Benedict formula to estimate BMR, which is then multiplied by your activity level to determine total daily energy expenditure.

For example, a sedentary lifestyle multiplies BMR by 1.2, while very active lifestyles use a factor of 1.725.

Example

For a 25-year-old male weighing 70 kg and 175 cm tall with moderate activity: The calculator estimates around 2,500 calories per day for weight maintenance. This is based on the BMR calculation adjusted for activity level.

Activity Levels

  • Sedentary: Little or no exercise, desk job
  • Lightly active: Light exercise 1-3 days a week
  • Moderately active: Moderate exercise 3-5 days a week
  • Very active: Hard exercise 6-7 days a week
  • Extra active: Very hard exercise, physical job, or training twice daily

  • Muscle gain: Ensure sufficient calorie surplus
  • Healthy lifestyle: Balance energy intake and expenditure
  • Disease prevention: Maintain optimal body weight
