## 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, walking at 4.5 mph (level, firm surface, very, very brisk) at a 7 MET value, burns 7 Kcal/kg x body weight/h.

A 70 kg individual walking at 4.5 mph (level, firm surface, very, very brisk) for 20 minutes expends the following:

(7 METs x 70 kg body weight) x (20 min/60 min) = 163.3 Kcal.

7 is the value in METs for walking at 4.5 mph (level, firm surface, very, very brisk).
