BMR

The Basal Metabolic Rate (BMR) is the number of calories you burn as your body performs basic life-sustaining functions. The Harris-Benedict Equation is often used to estimate basal metabolic rate (BMR), and this is the equation used for this calculator. However, you might want to consider a more recent and updated equation as the Harris-Benedict estimate tends to be a bit high or generous. Harris-Benedict BMR equation:

• Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years)
• Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)

TDEE

Total daily energy expenditure (TDEE) estimates how many calories your body burns daily by accounting for three contributing factors: the basal metabolic rate (BMR), the activity level and the thermic effect of food metabolism. To estimate the TDEE, we need to consider our activity level by multiplying the BMR with the appropriate activity level:

• Sedentary (little or no exercise)= BMR x 1.2
• Lightly active (light exercise/sports 1-3 days/week)= BMR x 1.375
• Moderately active (moderate exercise/sports 3-5 days/week)= BMR x 1.55
• Very active (hard exercise/sports 6-7 days a week)= BMR x 1.725
• Extra active (very hard exercise/sports & a physical job)= BMR x 1.9
