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)
|

|
Proteins = 17 kJ/g
|
|
|

|
A PAL of 3.4 - 4.4 would be indicative of walking uphil with a load, climbing stairs or exercise such as jogging, tennis etc. T/F
|
F - That is 6.0 - 7.9.
3.4 - 4.4 is standing or cleaning windows or walking |
|
|
BMR increases as body weight increase T/F
|
T (5% of adipose tissue is metabolically active tissue)
