REE (Resting Energy Expenditure) can be calculated from VO2 and VCO2 (Resting Energy Expenditure “REE”).
REE = [3.9 (VO2) + 1.1 (VCO2)] 1.44
VO2 = oxygen uptake (ml/min)
VCO2 = carbon dioxide output (ml/min)
Respiratory quotient (RQ) = VCO2/VO2
Here are my numbers from the start of my VO2max testing:
That number seems about right. This number is for sitting up in a chair and talking. This is a higher number than while sleeping.
From (Difference Between BMR and RMR):
Basal Metabolic Rate (BMR) and Resting Metabolic Rate (RMR) are rates used to estimate the amount of calories a person will burn if he is at rest for 24 hours.
Also known as Resting Energy Expenditure (REE), Resting Metabolic Rate is measured under less restrictive conditions than Basal Metabolic Rate. It does not require the person to spend the night in the testing facility to ensure at least 8 hours of sleep and rest before testing.
BMR is typically 10% less than RMR .
2374 / (1+.1) = 2158 kCals
Typical multipliers for activity are:
Choosing Sedentary (BMR x 0.2) : 2158 * 1.2 = 2589 kCal/day
That is a multiplier of 15.4 (kCal/lb). That seems like a pretty high number.
RER = 0.7 is 100% calories from fat
RER=1.0 is 100% of calories from carbs
%fat = 1-((RER-0.7)/0.3)
