Daily Calories Intake is determined based on the Basal Metabolic Rate (BMR) calculation.

The BMR calculation using Formula:

Woman: dci = 655 + 4.35 × w + 4.7 × h - 4.7 × age

Man: dci = 66 + 6.23 × w + 12.7 × h - 6.8 × age

Where:

**h**: Body height, in inches

**w**: Body weight, in pounds (lbs)

**age**: in years

**dci**: Basal Metabolic Rate, in calories

Harris Benedict Formula is then used for Daily Calories Intake calculation:

- sedentary, desk job: Calories = BMR x 1.2

- light exercise/sports 1-3 days/week: Calories = BMR x 1.375

- moderate exercise/sports 3-5 days/week: Caloriees = BMR x 1.55

- hard exercise/sports 6-7 days a week: Caloriees = BMR x 1.725

- very hard exercise/sports plus physical job: Calories = BMR x 1.9
