A quick count of the Social Psychology Eye blog reveals at least 8 posts related to weight, health, and eating behaviors. A quick diet search on the Internet will leave the individual with a plethora of websites to sort through. Eating and related topics have become so important because of the implications of food on our lives. Whether investigating the issue of overeating, not eating, perceived food restraint from food, or perhaps consuming a “manly” meal it is important to consider the contributing factors to understand eating behaviors. One phenomenon to consider for instance is the disinhibition effect where people are purportedly more likely to overeat after violating their diet. Diet violations are commonplace especially when considering all the possible places where food or snacks are sold and people’s disposition to eating junk food (refer to the November 7th post).
Recently researchers assessed the generalizability of the disinhibition effect (Tomiyama et al., 2009). The researchers selected female participants, who are more likely to practice restraint eating. Participants reported food consumption on an hourly basis. No evidence was found for the disinhibition effect. The experiment was repeated using female participants who reported restraint eating. In addition to regular reports of eating behavior participants were asked to stop by the laboratory and drink a milkshake. A manipulation designed as a diet violation. Again participants reported their eating behavior but no effect was found related to overeating. To the surprise of the researchers the participants compensated for over consumption by reducing calorie consumption. Researchers explain that participants who violated their diets perhaps succeeded in not overeating because they avoided additional foods whereas in the classic experiments participants would have been able to indulge by having access to the tempting food. While the findings highlight the importance of investigating eating behaviors the findings cannot be generalized to other age groups or to males. Some questions left unanswered are, outside of the lab, when might the disinhibition effect be most likely to occur, and with what population? Is it more likely to occur when participants are overweight? Lastly when does diet violation, which is ubiquitous, become a problem?
