The purpose of this study was to evaluate the efficacy of a weight management program using indirect calorimetry to set energy goals.


54 overweight, active duty adult employees of the US Air Force (age 18-46 years, BMI 25.2-35.6 kg/m2) participated in this quasi-experimental control design study. All participants were enrolled in a four-session US Air Force ‘Sensible Weigh’ group weight control program. Treatment participants received a personalized nutrition energy goal message developed using measured resting metabolic rate (RMR) from a hand-held indirect calorimeter (MedGem®). Usual care participants received a nutritional message using a standard care equation (25 kcal/day × body weight) to set energy intake goals.


Treatment participants lost significantly more weight than usual care participants (p ≤ 0.05). Difference in weight loss between the treatment and usual care group were -4.3 kg ± 3.3 vs. -1.8 kg ± 3.2, respectively. There were no significant differences in reported food intake or energy expenditure between groups.


The use of indirect calorimetry to assess RMR and set energy intake goals positively influences weight loss success in overweight Air Force personnel.
