Abstract
Objectives:Many individuals who smoke relapse due to weight gain. Mindfulness training has been shown to help smokers quit smoking, and, in other populations, has been used to help people lose weight. This study was designed to assess the effect of one week of mindfulness practice on food cravings in smokers during 12-hour smoking abstinence. Methods:We assessed daily smokers with a history of smoking lapse after weight gain. Participants were provided with brief training in mindfulness meditation and mindful eating and were asked to practice each skill daily for one week. Before and after this week of mindfulness practice, participants completed surveys to rate their nicotine dependence and food cravings and underwent testing via functional magnetic resonance imaging. Results:Study results included pre-post intervention reduction in brain activity in dorsomedial prefrontal cortex, visual areas, and pre-motor areas, regions potentially associated with response to food images. Conclusions:The study was small; however, it suggests the possibility that mindfulness training might be used to decrease food cravings after smoking cessation.

James Davis
Dr. James Davis is a practicing physician of Internal Medicine, and serves as the Medical Director for Duke Center for Smoking Cessation, Director of the Duke Smoking Cessation Program and Co-Director of the Duke-UNC Tobacco Treatment Specialist Credentialing Program. His research focuses on development of new pharmaceutical treatments for smoking cessation. He is principal investigator on several trials including a study on “adaptive” smoking cessation and several trials on new medications for smoking cessation. The new medications leverage more novel neurobiological mechanisms - NMDA receptor antagonism, nicotinic receptor antagonism, which impact addiction-based learning and cue response. Additionally, Dr. Davis serves as co-investigator on trials on lung cancer screening, e-cigarettes, minor nicotine alkaloids, imaging trials, lung function trials and others. Dr. Davis leads the Duke Smoke-Free Policy Initiative, is co-author on a national tobacco dependence treatment guideline, and provides training in tobacco dependence treatment for the Duke School of Medicine, Duke Internal Medicine, Family Practice and Psychiatry residency programs.
