Exercise May Thwart Weight Gain Post-Smoking Cessation
the MPR take:
Many individuals report weight gain following smoking cessation, but increasing or maintaining a high level of physical activity after quitting can lead to significantly less weight gain. In a randomized controlled study of 683 participants using different smoking cessation pharmacotherapies from 2005–2008, physical activity and body weight were measured in the days surrounding the day of smoking cessation (quit day) and once again the following year. Eighty-seven percent of patients who quit smoking gained weight compared to 59% of those who were unable to quit. However, those who did quit and decreased their physical activity levels over the year had a significantly greater weight gain vs. quitters who increased their physical activity or maintained a high level of activity. Physical activity is recommended for all, but it may be especially beneficial for those attempting to or who have quit smoking.
Method: Data were analyzed for participants (n = 683) of a randomized controlled trial comparing the efficacy of different smoking cessation pharmacotherapies (Wisconsin, 2005–2008). Activity (assessed via pedometry) and body weight were measured in the days surrounding the quit day and again one year later, at which time 7-day point-prevalence abstinence from smoking was assessed.
