BMI Can Affect Conscientiousness And Agreeableness

Neither personality traits nor individual answers to personality assessment statements could predict changes in body mass index. However, body mass index could predict future changes in the personality traits of conscientiousness and agreeableness. Individuals with lower body mass index values (i.e., lower body weight for their height) tended to a tiny bit more conscientious and agreeable on average compared to those with higher body mass index values.
