We evaluated the balance of energy consumption and expenditure on body weight change over one year in 430 healthy young adults. METHODS Over a 14‐day measurement period activity was objectively measured (BodyMedia armband) and diet was measured by 3 random 24‐hr recalls. Change in weight was calculated as measured weight at baseline minus self‐reported weight 1 year earlier. Total daily physical activity (TDEE) was stratified as low/sedentary (LSA, <3METS) moderate/vigorous (MVPA, 3+METS). Correlational analyses were performed on weight change and TDEE, total daily energy intake (TDEI), and the two activity levels. Variables were determined per kg of weight. Analyses were adjusted for age and race. RESULTS Women averages: 69.1±0.9 kgs, rTDEE=35.1±0.4 kcals/kg/day (KKD). Men averages: 81.3±0.9 kgs, rTDEE=39±0.4 KKD. Correlations (*significant, **very significant) with 1 year weight change were TDEE (−.231**), TDEI (−.122*), MVPA (−.187**), and LSA (−.076, NS). Correlations with TDEI were rTDEE (.444**), MVPA (.893**) and LSA (.164*). CONCLUSIONS Regulation of body weight is a complex interaction of physical, psychological and environmental factors. While absolute TDEE is dependent on body mass, rTDEE and rTDEI correlated most significantly with moderate and vigorous activity. These data suggest that how energy is expended is a critical component of energy balance.
