Washington: Adding a few kilos can make people more thoughtful about their actions but they are also more likely to give in to temptations, a new study has found. To understand how fluctuations in body weight might relate to personality changes, psychological scientist Angelina Sutin of the Florida State University College of Medicine and colleagues at the National Institutes of Health (NIH) examined data from two large-scale longitudinal studies of Baltimore residents. "We know a great deal about how personality traits contribute to weight gain," said Sutin. "What we don`t know is whether significant changes in weight are associated with changes in our core personality traits. Weight can be such an emotional issue; we thought that weight gain may lead to long-term changes in psychological functioning," Sutin said.
