Personality traits may play key roles in body weight.
Researchers examined data compiled over 50 years on nearly 2,000 generally healthy and highly educated people in America to determine how their personalities might affect their weight and body mass index. The participants were assessed on the so-called big five personality traits - openness, conscientiousness, extraversion, agreeableness and neuroticism - as well as 30 subcategories of these traits. They were also weighed and measured over the course of the study.
Although people tend to gain weight as they age, the study found those who are impulsive were the most likely to be overweight. People who scored in the top 10 percent on impulsivity weighed an average of 22 pounds more than those in the bottom 10 percent. Previous research has found that impulsive individuals are prone to binge eating and alcohol consumption. These behavioural patterns may contribute to weight gain over time.
It was found that people who are impulsive, cynical, competitive or aggressive were more likely to be overweight. And those who are highly neurotic and less conscientious are likely to see their weight go through many ups and downs. Individuals with this constellation of traits tend to give in to temptation and lack the discipline to stay on track amid difficulties or frustration. To maintain a healthy weight, it is typically necessary to have a healthy diet and a sustained programme of physical activity, both of which require commitment and restraint. Such control may be difficult for highly impulsive individuals.
Those who are risk takers, antagonistic, cynical, competitive and aggressive also had greater weight gain. On the flip side, it was found that conscientious people are typically thinner and their weight did not trigger changes in personality during adulthood. The pathway from personality traits to weight gain is complex and probably includes physiological mechanisms, in addition to behavioral ones.
Further research is however needed so that by more clearly identifying the association between personality and obesity, more tailored treatments can be developed. For example, lifestyle and exercise interventions that are done in a group setting may be more effective for extroverts than for introverts.
