## How to calculate calories (burned)

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

• the exercise you do
• 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, doing sit ups (vigorous effort) at a 8 MET value, burns 8 Kcal/kg x body weight/h.

A 70 kg individual doing sit ups (vigorous effort) for 40 minutes expends the following:

(8 METs x 70 kg body weight) x (40 min/60 min) = 373.3 Kcal.

8 is the value in METs for doing sit ups (vigorous effort).

(*) MET - Metabolic equivalent
