Smoking cessation is associated with gaining weight, and the fear of weight gain and/or actual weight gain may not only serve as a barrier to quitting, but may also facilitate recidivism. This post-cessation weight gain has been attributed to increased energy intake, decreased energy expenditure, or both. In order to better understand the interplay of these energy balance components, an exploratory analysis with eleven female smokers was conducted using a whole-room calorimeter to measure 24-hour total energy expenditure across three conditions: a smoking day, one day of abstinence, and 47 days post-cessation. Cessation was biochemically verified. Analyses showed that weight (kg) slightly increased from the smoking (x = 64.19, SD = 7.19) to day of abstinence assessment (x = 64.21; SD = 7.62), and further increased by the post-cessation assessment (x = 65.59; SD = 7.62), with a significant gain from the first to last assessment. Energy expenditure (kilocalories/kilogram mass) decreased from the smoking (x = 30.39, SD = 5.85) to day of abstinence whole-room calorimeter stay (x = 29.43, SD = 4.03), and further decreased by the post-cessation calorimeter stay (x = 27.91, SD = 3.41), with a marginally significant decrease from the first to last assessment. Finally, there was a mean non-significant decrease in caloric intake from the first (x = 29.99, SD = 5.84) to last assessment (x = 27.99, SD =7.94). These preliminary results suggest that future studies utilizing sophisticated energy expenditure techniques are warranted to better understand the relationship of energy balance components and cessation.

Learning Objectives:

1.Discuss the components of energy balance and how they may interact over time to contribute to the weight gain observed post smoking cessation.
• Identify the methodological problems when assessing components of energy balance.
• Evaluate the role of weight management techniques in smoking cessation interventions.
• Learn about the sophisticated methods for measuring energy expenditure.
