Objective:
To examine differences in resting energy expenditure (REE) between black and white smokers in order to determine whether REE might contribute to postcessation weight gain.
Design:
Cross-sectional and prospective investigation of ethnic differences in REE. Differences in REE between black and white smokers were examined at baseline while all participants were smoking, and again during 2 weeks of abstinence from smoking.
Setting:
Memphis, Tennessee, USA.
Subjects:
Sixty-six black and 112 white smokers (age 30.4 y; cigarettes per day 21.4; weight 71.7 kg; body mass index 24.5 kg/m2).
Results:
Black smokers had a significantly lower baseline REE after adjusting for gender and body weight. Changes in REE following smoking cessation did not differ by ethnicity.
Conclusions:
These results suggest that black smokers may be more energy efficient, which could contribute to ethnic differences in postcessation weight gain.
