Effects of three doses of transdermal nicotine on post-cessation eating, hunger and weight.

Smokers were randomly assigned to 0, 7, 14 or 21 mg doses of transdermal nicotine and had their eating and weight followed for 6 weeks. Among the 66 subjects who were abstinent for all 6 weeks, caloric, carbohydrate and fat intake, hunger, and weight increased in those on placebo, but alcohol, caffeine and protein intake did not. Nicotine patch decreased caloric, carbohydrate and fat intake in a dose-related manner, showed a trend for weight and showed no effect for hunger. Neither abstinence from smoking nor nicotine therapy shifted the percent of calories from sweets or carbohydrates. We conclude nicotine replacement reduces post-cessation increases in eating but does not have a specific effect on sweet intake.
