Indirect Calorimetry Measured REE vs Predicted

Compare measured resting energy expenditure from indirect calorimetry with predicted equations to guide clinical nutrition support.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Compare measured resting energy expenditure from indirect calorimetry with predicted equations to guide clinical nutrition support

Each component has a specific meaning:

  • Indirect calorimetry — The indirect calorimetry recorded for the scenario being assessed.

Note: Interpret the ic ree vs predicted result against the thresholds and context described above.

How to Use

Enter the indirect calorimetry for the scenario you are assessing. Compare measured resting energy expenditure from indirect calorimetry with predicted equations to guide clinical nutrition support. Use the ic ree vs predicted result to inform your calculation.
