The current BMR retrogression formula is a formula which acts on the principle of using the FFM value
from the results of body composition measurement according to the BIA, A good relationship is shown in
the BMR value based on actual breath analysis REE or R=0.9 (p<0.0001). These results were presented at the
First Annual Nutrition Week (American College of Nutrition, American Society for Clinical Nutrition,
American Society for Parenteral and Enteral Nutrition, North American Association for the Study of
Obesity) held in 2002 in San Diego.
NOTE: This model has been calibrated for those between ages of 18-84.
Those individuals outside of this age range may not be obtain accurate readings.
As shown in Figure 1: the REE (BMR) has a stronger relationship to the FFM than to body weight, and a
difference is visible between males and females in the distribution trends. We see that in principle that we
should calculate from the FFM rather than by the old formula centered on the relationship with weight.
