The objective of this study was to assess dried fruit mix and nuts and their effect on craving associated with the serum leptin of tobacco smokers. Materials and Methods:This is a clinical intervention study with a nonprobabilistic sample (n = 23). The intervention group (IG) received 30 g of dried fruit and mix, and the control group (CG) received standard interventions. Test craving was analyzed using the Questionnaire of Smoking Urges (QSU-Brief). Serum leptin was assessed at the beginning and after 3 weeks. The data was tested using the SPSS program through the Shapiro-Wilk, unpaired Student t, or Mann-Whitney tests and multivariate linear regression. Results:The study showed significant difference between initial and final weights and body mass indices. The IG showed a high degree of smoking dependence. The IG showed reduced craving. In the CG, median serum leptin levels showed increased craving in the second and third weeks. Conclusions:Our results establish that craving decreased among smokers only in the IG. In the CG, above-median serum leptin levels reported a greater sense of pleasure in the second week. And in the third week, they experienced difficulties maintaining abstinence.
