Description of Research
Each day we are confronted with choices, and many of these choices are related to food. Would you rather eat that cookie now or lose 5 lbs in a few weeks? An individual who consistently chooses the smaller reward that occurs sooner in time is considered impulsive. These impulsive choices have been shown to be associated with obesity. I am interested in further exploring the relationship between diet and impulsive choice behavior. Specifically, I want to determine how high-fat diets and high-sugar diets influence impulsive choice behavior. By gaining a better understanding of how diet influences impulsive choice behavior, we can develop interventions to improve impulsive choice. These interventions could be used in weight-loss treatment programs to improve weight-loss success.
