Toward a better understanding of durable behavior change by food Go/NoGo training

Abstract

Consistently not responding to appetitive foods during food Go/NoGo training (fGNG) influences subsequent food consumption and sometimes even body weight. Here, we review studies that examined the durability of fGNG effects. Previous work has not always found durable effects of fGNG in applied intervention studies, but recent controlled experiments show that a single session of fGNG can influence food choices for at least one week. By reanalyzing data from these controlled experiments, we show that this preference change is related to participants' memory of the trained stimulus-response contingencies. Examining the role of memory processes in fGNG may thus contribute to addressing challenges with creating durable behavior change through fGNG.
