The results of the study suggest that young people who have problems controlling and expressing their emotions, i.e. hiding their feelings or reacting with excessive aggression (e.g. shouting and slamming doors), are more likely to be overweight and obese than those who manage their anger better. According to the researchers, these individuals tend to isolate themselves and, instead of interacting with their peers, watch TV or read alone. These behaviours can, in turn, encourage poor eating habits and affect the risk of being overweight or even obese.
