1. Resting metabolic rate (RMR) or Basal metabolic rate (BMR)- It is the energy which is associated with the maintenance of major body functions.
2. The thermic effect of activity (TEA) or Activity thermogenesis- It is the energy expenditure due to physical work, muscular activity or physical exercise and it is controlled by a person.
3. The thermic effect of feeding (TEF) or Thermogenic foods-It is the energy expenditure after several meals and it refers to calories used to digest different kind of foods you eat.
