AB  - BACKGROUND: The energy intake necessary to maintain weight and body composition 
      is called the energy requirement for weight maintenance and can be determined by 
      using the doubly labeled water (DLW) method. OBJECTIVE: The objective was to 
      determine the energy requirements of nonobese men and women in the Comprehensive 
      Assessment of Long-Term Effects of Reducing Intake of Energy 2 study. DESIGN: 
      Energy requirements were determined for 217 healthy, weight-stable men and women 
      [aged >21 to <50 y; 70% female, 77% white; body mass index (BMI; in kg/m(2)) 22 
      to <28; 52% overweight] over 28 d with 2 consecutive 14-d DLW assessments in 
      addition to serial measures of body weight and fat-free mass and fat mass by 
      dual-energy X-ray absorptiometry. Energy intake and physical activity were also 
      estimated by self-report over >/=6 consecutive d in each DLW period. RESULTS: Total 
      daily energy expenditure (TDEE) was consistent between the 2 DLW studies (TDEE1: 
      2422 +/- 404 kcal/d; TDEE2: 2465 +/- 408 kcal/d; intraclass correlation coefficient = 
      0.90) with a mean TDEE of 2443 +/- 397 kcal/d that was, on average, 20% (580 
      kcal/d) higher in men than in women (P < 0.0001). The regression equation 
      relating mean TDEE to demographics and weight was as follows: TDEE (kcal/d) = 
      1279 + 18.3 (weight, kg) + 2.3 (age, y) - 338 (sex: 1 = female, 0 = male); R(2) = 
      0.57. When body composition was included, TDEE (kcal/d) = 454 + 38.7 (fat-free 
      mass, kg) - 5.4 (fat mass, kg) + 4.7 (age in y) + 103 (sex: 1 = female, 0 = 
      male); R(2) = 0.65. Individuals significantly underreported energy intake (350 
      kcal/d; 15%), and underreporting by overweight individuals (~400 kcal/d; 16%) was 
      greater (P < 0.001) than that of normal-weight individuals (~270 kcal/d; 12%). 
      Estimates of TDEE from a 7-d physical activity recall and measured resting 
      metabolic rate also suggested that individuals significantly underreported 
      physical activity (~400 kcal/d; 17%; P < 0.0001). CONCLUSION: These new equations 
      derived over 1 mo during weight stability can be used to estimate the free-living 
      caloric requirements of nonobese adults. This trial was registered at 
      clinicaltrials.gov as NCT00427193.
