How to calculate calories (burned)

The number of calories you burn while exercising is dependent on:

• the exercise you do
• your weight
• the time spent doing the activity

By multiplying the MET ^(*) value by the body weight in kg and the duration of the activity, you can estimate the energy expenditure in Kcal specific to a person's body weight. This statement can be expressed as the following formula:

In this example, sitting quietly at a 1.3 MET value, burns Kcal/kg x body weight/h.

So, a 70 kg individual sitting quietly for 40 minutes expends the following:

(1.3 METs x 70 kg) x (40 min/60 min) = 60.7 Kcal.

Notes:

• 1.3 is the value in METs for sitting quietly
• The time unit is expressed in minutes
• The mass (weight) unit is expressed in kilograms
• We divide the time by 60 (min) because the MET unit uses hour.

(*) MET means 'metabolic equivalent'
