Resting Energy Expenditure is Overpredicted in Midlife Females: Examining the Accuracy of Predictive Equations and the Role of Lean Soft Tissue in Perimenopause

Key Points

• This research investigates the accuracy of predictive equations for resting energy expenditure (REE) in perimenopausal women.
• Comparative analysis of estimated and measured resting energy expenditure (mREE) in midlife females.
• Evaluation of different predictive equations for accuracy in estimating caloric needs.
• Estimated REE overestimated caloric needs by an average of ∼215 kcals/day.
• The MS equation provided the most accurate estimates for midlife women.
• Lean soft tissue did not significantly influence differences between mREE and predictive estimates.
