Abstract

One factor that may encourage smoking despite its known adverse health consequences is its association with weight control. Middle‐aged and older smokers weigh less than comparably aged non‐smokers but smoking has minimal impact on body weight in young smokers. Smoking cessation produces weight gain in both men and women, although the magnitude of this gain and the mechanisms involved are unclear. Physical activity does not appear to be a factor. The effect of smoking cessation on energy intake is complicated, with few studies looking at changes after long periods, but there do seem to be sustained increases in energy intake in women. Removal of the acute increases in metabolic rate caused by smoking may contribute to post‐cessation weight gain but there are no reliable long‐term changes in metabolic rate after cessation. Behavioural and pharmacologic interventions to prevent weight gain after cessation are described.
