This simple form are absorb into the blood stream and supply to the millions of cells in the body to be oxidised to released energy.  Energy balance is state of equilibrium between energy intake and total energy expenditure. Energy intake comes from food and energy expenditure come from voluntary and involuntary activity deviation in energy balance food lied to malnutrition, underweight and overweight. Energy expenditure is a total amount of energy spend in 24 hours. Predominantly their are 3 components of    energy  expenditure 1) BMR 2) Thermic effect of food.  3) Physical activity.  AI-Adequate Intake: The average nutrient levels consumed daily by a typical healthy population that is as
