## 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, sitting at a desk at a 1.3 MET value, burns 1.3 Kcal/kg x body weight/h.

A 70 kg individual sitting at a desk for 40 minutes expends the following:

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

1.3 is the value in METs for sitting at a desk.

(*) MET - Metabolic equivalent
