Calorie Calculator

Know how many calories are burnt mopping the floor?

The calorie calculator calculates the amount of average calories you would burn at your selected activity, multiplies it by the duration of the activity and then by your weight. What you get then, is an estimation of how many calories you've burned during that activity. This offers you the opportunity to make sure that you're food intake is not in excess of the calories you burn during exercise.

Calorie Requirement Calculator

The calculator uses the following formula's:

BMI (Body Mass Index) formula

BMI = weight [kg] /(height [m] x height [m])

• Healthy BMI = 18.5 to 24.99
• Overweight BMI = 25 to 29.99
• Obese BMI = 30 to 34.99
• Very obese BMI = >35
• Underweight BMI = < 18.5

Formula for calorie requirements for Men & Women

Men 19 years and over

Calorie Requirements = 864 - (9.72 × age [y]) + PA × (14.2 × (22.5 x height [m] x height [m]) + 503 × height [m])[1]

Where PA is the physical activity coefficient:

1. PA = 1.00 if activity is less than 30 minutes
2. PA = 1.12 if PAL is 30 to 60 minutes
3. PA = 1.27 if PAL is 60 minutes or more

Women 19 years and over

Calorie Requirements = 387 - (7.31 × age [y]) + PA × (10.9 × (21.5 x height [m] x height [m]) + 660.7 × height [m])^[1]

Where PA is the physical activity coefficient:

1. PA = 1.00 if PAL is less than 30 minutes
2. PA = 1.14 if PAL is 30 to 60 minutes)
3. PA = 1.27 if PAL is estimated 60 minutes or more

The calculator rounds the calorie requirement to the nearest 100 calories.
