Nowadays, obesity is a major problem in societies globally which not only causes complications and disorders in physiologic health of obese persons, but also affects psychologic health and self-confidence adversely. In this research, we intended to compare cognitive-executive functions of the frontal lobe of the brain and lifestyle self-efficacy in persons with different body mass indices (BMI). Three-hundred subjects with different BMI values were recruited via convenience sampling method. The questionnaires used included the Wis-consin Card Sorting Test, and the questionnaires for executive function disorder, lifestyle self-efficacy, and the general health. For data analysis, descriptive indices (mean, frequency) were used and for inferential indices, analysis of variance (ANOVA) was applied. The re-sults showed that there is significant (P= 0.05) difference regarding attention shifting between persons with different BMI values. In sub-jects with different BMI values, cognitive functions are different, and reduced cognitive function was higher in those with higher BMI. Al-so, lifestyle self-efficacy was lower significantly (P = 0.05) in obese subjects compared to those with normal weight. Persons with differ-ent BMI values had different cognitive functions.
