Energy expenditure in the post-absorptive state; measured under standardised conditions of thermal neutrality, awake but completely at rest.
Basal Metabolic Rate (BMR)
Energy expenditure at rest, not measured under strictly standardised conditions
Resting Metabolic Rate (RMR)
Energy cost of physical activity, expressed as a ratio of BMR
Physical Activity Ratio (PAR)
Sum of PAR * time spent in each activity over 24 hours, expressed as a ratio of BMR (desirable = 1.7, average = 1.4)
Physical Activity Level (PAL)
Increased energy expenditure after a meal; the energy cost of digestion and absorption, plus cost of synthesising reserves of glycogen, fat and protein; may be 10-15% of energy yield of a meal
Diet-Induced Thermogenesis (DIT)
PAL * BMR (+DIT) =
Total Energy Expenditure (TEE)
