24 ARM:
24 hour Activity Recall Method abbreviated 24 ARM is a simple way to calculate the average energy spent in a day. It considers all 3 components energy is spent and so is considered to give values close to true values, being valid and reliable.

Using 24 ARM:
*Resting Energy Expenditure (REE) is calculated using age (in years), weight (in kilograms), height (in cms). It is equivalent to Basal Metabolic Rate (BMR).

*Activity Energy Expenditure (AEE) is calculated with the list of activities a particular person does over a 24 hour period. Activities and duration are obtained by 24 hour recall method.

*The summary tells us the Total Energy Expenditure (TEE) along with its 3 components which can be shared with the person it is calculated for!
