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 body weight in kg by the MET (*) value and duration of activity, you can estimate the energy expenditure in Kcal specific to a persons body weight. In this example, running (marathon) at a 13.3 MET value, burns 13.3 Kcal/kg x body weight/h.
A 70 kg individual running (marathon) for 30 minutes expends the following:
(13.3 METs x 70 kg body weight) x (30 min/60 min) = 465.5 Kcal.
13.3 is the value in METs for running (marathon).
(*) MET - Metabolic equivalent
