Data from a population representative household survey reveal that limited self-control is strongly associated with both objective and subjective measures of unhealthy body weight. Those with limited self-control are characterized by reduced exercising, repeated dieting, unhealthier eating habits, and poorer nutrition. We propose an empirical method to isolate two facets of self-control limitations—high impulsivity and low restraint. Each has differential predictive power. Physical activity, dieting, and overall body weight are more strongly associated with restraint; impulsivity is more predictive of when, where, and what people eat. %K body mass index %K obesity %K brief self-control scale %K diet %K exercise
