It helps convert food into energy, breaking down food into building blocks for various elements, and to eliminate nitrogenous wastes from the body.

The energy value of any food is measured in calories, and the basal metabolic rate is the minimum amount of calorie count that is required when the body is at rest (Resting Energy Expenditure). Combining it with the energy one consumes while moving around or digesting food gives us the total energy expenditure.

Our body energy needs are dependent on our age, height, weight, genetics and gender, apart from our daily activity.
