A new study found that your personality can have an effect on your weight. The more impulsive people are, the more they tend to weigh. Those ranked on top of the conscientiousness scale are likely to weigh less.
Mean people tend to gain weight during their adult life, which results in a higher Body Mass Index (BMI).
Neurotic and disagreeable people are also likely to weigh more.
The study by Maastricht University coincides with other studies conducted earlier. In total, the more interesting your character is, the more likely you are to get fat.
