摘要:The worldwide obesity epidemic brings with it health-related, psychological and social problems and consequently a dramatic increase in health costs. Something needs to be done to stop or even reverse this trend and psychological and environmental factors seem to be our best bet. One psychological factor with potential is impulsivity. Research in populations that typically overeat (the obese and Bulimia Nervosa patients), in populations that are typically impulsive (e.g. Attention Deficit Hyperactivity Disorder patients) and in healthy participants has indeed begun to indicate that impulsivity plays a role in the problem of overeating. However, more research including actual food intake and true experimental research is needed to conclude that impulsivity actually causes overeating in the short term and possibly overweight or even obesity in the long run.
