Weight gain after smoking cessation was studied in a naturalistic sett
ing where (1) all smokers quit and (b) risk factors for postcessation
weight gain were modified. Participants were 332 military recruits (22
7 men, 105 women), 86 of whom were smokers who quit during 6 weeks of
basic training. Results showed no significant weight changes for smoke
rs who quit. Pretest smoking rates and feat of weight gain were unrela
ted to changes in weight. Results suggest that an intensive program th
at limits access to alcohol and foods that are high in fat and that in
creases physical activity can attenuate weight gain after smoking cess
ation.
