Abstract
A range of lifestyle modifications are associated with differing rates of successful smoking abstinence. Most research on lifestyle modification has focused on physical activity (PA) and calorie restriction, though little research has explored whether dietary modifications related to macronutrient intake are differentially related to smoking abstinence rates. The current study addressed the gaps in the literature by exploring the associations between changes in PA, calorie intake, and macronutrient intake with smoking cessation. It was hypothesized that increases in PA duration, added sugar and saturated fat would be associated with greater rates of successful abstinence. Adults who smoked (N=325) received an 8-week smoking cessation intervention. Logistic regression models tested whether changes in calorie and macronutrient intake (saturated fat, added sugar, fiber, and protein) and PA duration were associated with smoking abstinence (yes/no for 7-day point prevalence abstinence, confirmed by carbon monoxide test) at end-of-treatment and 26-week follow-up. Results showed that increases in protein intake from baseline to 26-week follow-up were significantly associated with improved abstinence rates (p = .009) and increases in saturated fat were associated with lower abstinence rates, at trend-line significance (p = .085). Changes in PA and calorie intake were not significantly associated with smoking abstinence (ps > .198). When the relative contributions of changes in PA, calorie and macronutrient intake were compared, macronutrients (particularly increases in protein) explained the greatest amount of variance in abstinence. These findings highlight the importance of macronutrient intake in relation to smoking abstinence and show how a comprehensive approach to smoking cessation may include specific dietary recommendations, with a focus on increasing protein intake.
