Adherence

Sociopathy (defined by antisocial/aggressive behavior in childhood/adolescence) is strongly associated with being overweight, but is NOT associated with the rate of weight gain (BMI slope).

A history of antisocial or aggressive behavior in youth is a strong predictor of being overweight in adulthood, even if it doesn't predict how fast you gain weight. This suggests that early interventions targeting behavioral regulation may have long-term benefits for weight maintenance.
