Dr Sarah Henes, PhD and her colleagues at the Georgia State University Department of Nutrition have published a study indicating the KORR ReeVue is reliable and valid for assessing Resting Metabolic Rate (RMR) when compared with the CosMed Quark, a traditional metabolic cart 3-5 times more expensive. The study specifically tests ReeVue’s reliability and validity for assessing RMR in an overweight and obese adolescent population.

Highlights from the discussion include:

• This study demonstrates that there was no significant difference in measured RMR (kcal/d) when comparing the portable indirect calorimeter with a traditional indirect calorimeter. Data indicate that the portable indirect calorimeter used in this study (ReeVue) is both reliable and valid compared with the traditional indirect calorimeter.
• It demonstrates a clinically relevant example of comparing predicted and measured RMR in 2 female individuals who “look” the same based on sex, height, weight, and age but are, in fact, very different. While the predictive equations would estimate each patient’s RMR as essentially the same, actual measured RMR was approximately 200-390 kcal/d lower in one participant and 155-270 kcal/d higher in the other participant.  The clinical importance of this is paramount and indicates that more accurate nutrition recommendations may be determined by measuring an individual’s RMR rather than estimating RMR using predictive equations in overweight and obese adolescents.
• Ultimately, more accurate nutrition and weight management recommendations on an individual basis may lead to more successful outcomes when working with overweight and obese adolescent patients in the clinical setting.
