Metabolism:
Basal Metabolic Rate (BMR) or Resting Metabolic Rate
(RMR) is the daily amount of energy expenditure by thebody at rest, or it is the minimum calories needed for thebody to function properly at rest.

Factors affecting BMR:
GeneticsGender: men have higher BMR than women.
Age: BMR reduces by age. After 20 years old, it deceases 2%per decade.

How to Calculate BMR:
The Harris-Benedict formula:
Men: BMR = 66 + (13.7 X wt in kg) + (5 X ht in cm) - (6.8 X age in years)
Women: BMR = 655 + (9.6 X wt in kg) + (1.8 X ht in cm) - (4.7 X age in
years)
Example: You are female You are 30 years old
You are 5' 6 " tall (167.6 cm) You weigh 120 lbs. (54.5 kilos) Your BMR = 655 + 523 + 302 - 141 = 1339 calories/day

Total Daily Energy Expenditure (TDEE):
is the total amount of calories that your body expends in 24hours, including all activities.
TDEE = BMR X Activity Multiplier
Activity Multiplier Sedentary = BMR X 1.2 (little or no exercise, desk job)Lightly active = BMR X 1.375 (light exercise/sports 1-3 days/wk)
Mod. active = BMR X 1.55 (moderate exercise/sports 3-5 days/wk) Very active = BMR X 1.725 (hard exercise/sports 6-7 days/wk)Extr. Active = BMR X 1.9 (hard daily exercise/sports & physical job or 2X day
training, i.e. marathon, contest etc.)

TDEE:
Example:
Your BMR is 1339 calories per day Your activity level is moderately active (work out 3-4times per week) Your activity factor is 1.55 Your TDEE = 1.55 X 1339 = 2075 calories/day

Calorimetery:
it is measuring the heat produced by chemical reactionsor physical changes of the body.
Direct Calorimetry :
Serves as the standard interpretation of energyexpenditure. However, direct calorimeters are difficultdevices to operate.
The whole body is placed inside the calorimeter for themeasurement.

Calorimetry:
Indirect Calorimetry:
is the preferred method to estimate metabolic energyconsumption in the body (BMR).
It measures the exchange of respiratory gases: O2 uptake,and Co2 production, and ventilation.
