A new study has found that significant changes in weight are associated with changes in our core personality traits. People who gain weight are more likely to give in to temptations but also are more thoughtful about their actions, the study concluded.
Psychological scientist Angelina Sutin of the Florida state university and colleagues at the National Institutes of Health found that participants who had at least a 10% increase in body weight showed an increase in impulsiveness - with a greater tendency to give in to temptations - compared to those whose weight was stable.
In a surprising twist, people who gained weight also reported an increase in deliberation, with a greater tendency to think through their decisions. Deliberation tends to increase for everyone in adulthood, but the increase was almost double for participants who gained weight compared to those whose weight stayed the same.
