Predictive equations commonly used in the clinic underestimate resting energy expenditure compared with whole-room indirect calorimetry in colorectal cancer survivors

Key Points

• Resting energy expenditure was underestimated by common predictive equations in colorectal cancer survivors, highlighting potential clinical inaccuracies.
• The Harris-Benedict, Henry, and FAO/WHO/UNU equations demonstrated the best accuracy and agreement with whole-room indirect calorimetry.
• Observational analysis utilized whole-room indirect calorimetry to evaluate resting energy expenditure in colorectal cancer survivors over a significant time period.
• Improved predictive equations are necessary as existing methods show individual variability and may not accurately reflect energy needs in this population.
