How impulsiveness and variety influence food intake in a sample of healthy women.

This study investigates to what extent an impulsive personality, a varied food environment and their interaction influence food intake. We also investigated whether high-impulsives would exhibit more "eating disordered" thoughts and behaviours. Forty-five low-impulsives and forty-one high-impulsives did a bogus taste test with varied or monotonous food. As expected, high impulsives had a higher food intake compared to low impulsives. Moreover, high-impulsives reported significantly more "eating disordered" thoughts and behaviours than low-impulsives. Neither a main effect of variety nor an interaction between variety and impulsivity were found.
