Basal Metabolic Rate (BMR) Calculation:
BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age in years) + S
- S = +5
- S = -161
Example: a 30-year-old woman, 165 cm tall, weighing 60 kg
BMR = (10 x 60) + (6.25 x 164) - (5 x 30) + 5 = 600 + 1025 - 150 - 161 = 1315 kcal
BMR = (10 x 60) + (6.25 x 164) - (5 x 30) + 5 = 600 + 1025 - 150 - 161 = 1315 kcal
This formula is widely used to estimate the basic daily caloric requirement. It is important to remember that it is only an estimate and may vary based on individual factors such as body composition, physical activity level, and genetics.
Daily Protein Requirement Calculation:
P = weight in kg x f
- f = 0.8 for sedentary
- f = 1.4 for active
- f = 2.0 for strength athletes
Example: Woman weighing 60 kg with moderate activity (1.4)
P = 60 x 1.4 = 84g
P = 60 x 1.4 = 84g
This is not a medical prescription. These calculations are purely indicative and based on statistical averages. Users with kidney or liver diseases should consult a doctor before increasing protein intake. The calculation refers to total protein (both animal and plant) consumed throughout the day.
