Physical activity and food consumption: The moderating role of individual dieting tendency
Journal of Health Psychology
Abstract
Applying theory on justification and self-control, this research examines the impact of physical activity on dieters' and nondieters' food consumption patterns. The results from two studies demonstrate that dieters, but not nondieters, consume more food after exercising as compared to situations in which no exercise is involved. In addition, dieters consume more food when they anticipate engaging in physical activity as compared to when they have completed their exercising. When physical activity is framed as fun (vs work), dieters decrease the amount of food they consume after exercising. Estimation of calories burned through exercise underlies this result.

... Heydari, et.al., 2015), and diet or food intake (i.e. Chang & Lin, 2015;Jayawardene, Torabi, &Lohrmann, 2015) have been investigated in previous studies. However, since physical behaviors are likely to be related to one another, a simultaneous analysis of several physical indicators should be considered alongside exercise to provide a more comprehensive assessment of healthy lifestyle. ...
Exercising on a regular basis is generally associated with other healthy lifestyle behaviors. In this study, the healthy lifestyle behaviors of young professional women who regularly exercise and those who do not was compared in terms of cigarette consumption, alcohol consumption, diet preferences, physical activity, and overall healthy lifestyle index. The study used a comparative quantitative research design. The Healthy Lifestyle Questionnaire was used to gather data from the respondents. Eighty young women professionals, 45 of whom regularly exercise and 35 who do not exercise at all participated in the study. T-test was used to compare the scores of the respondents in terms of cigarette consumption, alcohol consumption, diet preferences, and physical activity. On the other hand, median test was used to compare the overall healthy lifestyle indexes of the two groups. Results reveal that there was no significant difference in cigarette and alcohol consumption between women who regularly exercise and those who do not. On the contrary, there were significant differences in terms of diet preferences, physical activity, and overall healthy lifestyle, in favor of women who regularly exercise.
... These pertain to beliefs that an unhealthy behavior can be compensated for by engaging in a healthy behavior and were found to hinder health behavior change (Amrein et al., 2017). This has also been labeled in other literature as the "licensing effect" (Khan & Dhar, 2006), that is, when people allow themselves to do something "bad" (e.g., immoral or unhealthy) after doing something "good" (e.g., moral or healthy), including food choices (e.g., Chang & Lin, 2015;Prada et al., 2016;Prinsen et al., 2019). These compensatory beliefs or licensing effects may help to explain why some participants assumed they could eat more sugar, namely due to following a vegan diet or because they practice physical exercise regularly. ...
Excessive sugar intake has been associated with multiple health conditions (e.g., higher risk for non-communicable diseases). Hence, health organizations have issued guidelines defining the maximum daily intake of free or added sugars. However, data from several countries suggests that these guidelines are rarely met, particularly by young adults. For example, almost half of Portuguese adolescents and young adults exceed the recommended sugar intake. In this work, we aim to further explore college students' attitudes, knowledge, and perceptions about sugar intake, as well as about sugar intake guidelines. A thematic analysis on data from five focus groups (N = 40) indicated that participants reported difficulty in the comprehension of added/free sugars definition and sugar intake recommendations. Overall, attitudes toward sugar were ambivalent. Sugar was simultaneously perceived as pleasurable and needed, but also as addictive and harmful. Although aware of the potential negative health outcomes associated with excessive sugar intake, most participants did not perceive being at risk due to their youth, exercise habits, or type of diet. The few concerns expressed were mostly associated with the negative impact of high sugar intake on body image (e.g., weight gain). The main barriers to reducing sugar intake identified were environmental (e.g., time restrictions, food available at the university). Still, participants could identify several individual strategies to effectively regulate sugar intake. By identifying knowledge gaps and sources of bias related to sugar consumption, our findings are useful to inform future interventions aiming to address the problem of high sugar intake among university students.
... When they labelled the physical activity as 'fun', participants ate less dessert and fewer hedonic snacks afterwards than when it was labelled as 'exercise'. Similar results were found by Chang and Lin (2015). They only found a licensing effect of physical activity on food consumption for dieters, but not for non-dieters. ...
When people engage in physical activity they often report that it alters the way they think and feel. These lay beliefs are generally supported by research on the cognitive benefits of physical activity. But despite the evidence on benefits of physical activity for cognition, little research has investigated whether physical activity has any effect on judgment and decision making, particularly in unrelated domains such as consumer decision making. This thesis presents seven empirical studies which demonstrate that both regular and single bouts of physical activity influence consumers’ product judgments and decision making. Specifically, the key results indicate that physical activity leads decision makers to weigh different product information more appropriately. The results were robust to the inclusion of various control variables. In the first part of this thesis, five studies investigate the effect of physical activity on decision makers’ ability to rely on relevant versus irrelevant information. Past research has shown that when faced with irrelevant product information, consumers often find it difficult to ignore the irrelevant information, and typically dilute their judgments (i.e. their judgments are less extreme). In contrast, the results of this research show that regular physical activity aids people’s ability to focus on relevant information and ignore irrelevant information in product judgments. In the second part of this thesis, three further studies indicate that physical activity influences attribute weighting in consumer decisions that require trade-offs between desirability and feasibility attributes. Decision makers tend to place a lot of emphasis on the desirability attributes, often at the expense of feasibility attributes. The findings of this research indicate that physical activity leads consumers to not overly focus on desirability, and consider feasibility attributes more in choices that require trade-offs between them. The findings have important implications for marketing and public policy since they extend the benefits of physical activity to a novel domain – information processing in consumer decision making.
... This area of research also stands to gain important insights from testing specific strategies to enhance engagement and/or weight loss outcomes in future BWL programs designed for this population. For example, efforts might include targeting executive functioning domains that predict consumption of fruits/vegetables and high-fat foods in young adults (Limbers & Young, 2015) or explicitly offering and/or marketing "fun" experiential physical activity classes, which has been shown to decrease compensatory eating among young adult dieters (Chang & Lin, 2015) and is consistent with our formative data which indicated a desire for fun and experiential activities as part of BWL programs (LaRose et al 2016). ...
Emerging adults are at high risk of obesity but behavioral weight loss programs do not meet their needs. Emerging adults (N = 52, age = 22.3 ± 2 years, body mass index = 34.2 ± 5.5 kg/m², 46.2% non-Hispanic White) were randomly assigned to one of three behavioral weight loss programs adapted based on formative work: face-to-face behavioral weight loss, web-based behavioral weight loss, or web plus optional community sessions (Hybrid). Assessments occurred at 0 and 3 months. Engagement and self-monitoring were highest in Hybrid. Intent-to-treat weight losses were −2.8 ± 2.9 percent in face-to-face behavioral weight loss, −2.2 ± 4.5 percent in web-based behavioral weight loss, and 4.8 ± 4.9 percent in Hybrid. Percent achieving ⩾5 percent weight loss was highest in Hybrid (63%). Findings suggest potential for adapted behavioral weight loss to promote engagement and weight loss in emerging adults.
... weekly moderate-high intensity exercise and use of at least one weight gain prevention strategy,Serdula et al., 1999; defined as 150 minutes of exercise per week and reducing calories inWammes et al., 2007;see Marks, 2016for a discussion of the need to consider other factors than simply diet and exercise). However, dieters who anticipated exercise or viewed exercise as work (rather than fun) consumed more food compared to when no exercise was anticipated (Chang and Lin, 2015). ...
We modified the Weight Control Behaviours scale to explore unhealthy/healthy behaviours to increase, decrease or maintain weight in young adults (N = 1082) and associations with body mass index, depression and body image. Females reported more use of all strategies except those which increase body size or exercising to exhaustion. Although the sample reported more use of healthy weight management strategies, the use of dangerous ones warrants attention by healthcare professionals. Feelings of fatness was an important predictor of weight management behaviours. Public health campaigns should focus on the harmfulness of unhealthy weight management practices as well as the importance of healthy ones.
... However, restrained eaters tend to consume larger amounts of high-calorie snacks (e.g. potato chips) and show a compensation pattern as soon as they have a justification, for example in the form of physical activity (Chang & Lin, 2015). Accordingly, a few longitudinal studies found a significant positive effect of dietary restraint on weight gain for women (Chaput et al., 2009;van Strien, Herman, & Verheijden, 2014). ...
In a random sample from the general population (N = 2781, 46% males), a longitudinal survey was conducted. The association between dispositional self-control and changes in eating behaviors and diet quality were analyzed between the first wave (2010) and the last wave (2014). Results show that the higher the dispositional self-control, the lower the increase in overeating behaviors (emotional eating, external eating, ambivalence toward palatable food and overeating), and BMI and the larger the improvement in healthy diet over time. Self-control was not associated with changes in dietary restraint. This is one of the first studies suggesting that dispositional self-control is associated with changes in eating behaviors and healthy food intake over time.
... Indeed, these results are in line with recent evidence regarding the relation between exercise and food consumption. For example, Chang and Lin (2015) showed that after exercising (vs. no exercise) dieters consumed more food, especially if exercising was framed as "work". ...
Organic claims can influence how a product is perceived in dimensions that are unrelated with the food production method (e.g., organic food is perceived as more healthful and less caloric than conventional food). Such claims can also bias how the consumers of organic food are perceived and how other people judge their behavior. Schuldt and Schwarz (2010) have shown that individuals evaluating a target with a weight-loss goal are more lenient in judging the target forgoing exercise when the target had an organic (vs. conventional) dessert. This impact of organic claims on leniency judgments has been interpreted either as a halo or a licensing effect. In the current research we aim to replicate and extend Schuldt and Schwarz's (2010) results by examining the mechanisms that are more likely to explain the observed leniency judgments. In Experiment 1, we observed that leniency towards a target that has consumed an organic meal is only observed when the target intentionally chooses such organic meal (vs. choice determined by the situation). These findings suggest that the impact of organic claims on leniency judgments is not merely based on a halo effect. Instead, a licensing account emerges as the most probable mechanism. In Experiment 2, we further found that stronger (vs. weaker) motives for forgoing exercise influenced leniency judgments to the same extent as having had an organic meal. Understanding the mechanisms that shape consumers’ decisions may have important implications to prevent bias in their judgments about food and exercise.
... Alternatively, walking as a form of exercise may have triggered overeating in restrained eaters due to compensatory process and the need for energy balance. This supports a recent study that showed that dieters consumed more after exercise compared to a no-exercise situation (Chang and Lin, 2015). However, this seems unlikely given the low intensity of the activity which involved 5-minutes walking along the corridor. ...
To assess the impact of distraction on subsequent eating, 60 females consumed a cereal bar while watching TV, walking or talking, and their subsequent desire to eat and food intake were assessed. No effects were found for desire to eat. But while those higher in restrained eating consumed less overall and fewer calories after watching TV or talking, they consumed more overall and more calories (specifically five times more chocolate) if the cereal bar was eaten while walking. 'Eating on the go' may disinhibit restrained eaters either as a form of distraction or by offering a justification to overeat.

This longitudinal study was conducted between 2010 (T1) and 2014 (T2) on a random sample from the general Swiss population (N = 2781, 46% male). Results showed that dieters (restrained eaters) who reported lack of success in T2 were overweight in T1, had higher levels of emotional and external eating, overeating, and ambivalence toward eating palatable food in T1, and a significantly increased body mass index (BMI) in the period between T1 and T2. Dieters who reported success in T2 had maintained a normal BMI between T1 and T2, had a higher diet quality in T1 and had maintained regular physical activity for at least one year before T2. The logistic regression revealed that high levels of dispositional self-control provided the most important predictor of being a successful dieter. When controlling for dispositional self-control, high levels of emotional eating, overeating, and ambivalence in T1, together with increases in these levels between T1 and T2, were associated with a decreased likelihood of being a successful dieter in T2. High levels of diet quality in T1 and the maintenance of regular physical activity were associated with an increased likelihood of being a successful dieter in T2. Results suggest that diet success and failure is a long-term phenomenon, partly but not fully explained by dispositional self-control. Independent of self-control persistent patterns of overeating due to emotional eating and ambivalent feelings toward eating palatable food, also explain long-term diet failure. A high diet quality and maintenance of regular physical activity accounted for dieters' long-term success. This is the first study that examined the long-term psychological and behavioral characteristics of successful and unsuccessful restrained eaters.
This study examined the effect of anticipated food deprivation on intake in restrained and unrestrained eaters. Participants were randomly assigned to a diet condition, in which they expected to diet for a week, or to a control (no-diet) condition. Immediately after being assigned to a condition, participants completed a taste-rating task in which food consumption was measured. Restrained eaters in the diet condition consumed significantly more food than did restrained eaters in the no-diet condition or unrestrained eaters in either condition. Unrestrained eaters consumed the same amount regardless of condition. These results confirm that merely planning to go on a diet can trigger overeating in restrained eaters, reflecting the dynamic connection between dieting and overeating.
Three experiments supported the hypothesis that people are more willing to express attitudes that could be viewed as prejudiced when their past behavior has established their credentials as nonprejudiced persons. In Study 1, participants given the opportunity to disagree with blatantly sexist statements were later more willing to favor a man for a stereotypically male job. In Study 2, participants who first had the opportunity to select a member of a stereotyped group (a woman or an African American) for a category-neutral job were more likely to reject a member of that group for a job stereotypically suited for majority members. In Study 3, participants who had established credentials as nonprejudiced persons revealed a greater willingness to express a politically incorrect opinion even when the audience was unaware of their credentials. The general conditions under which people feel licensed to act on illicit motives are discussed.
This study investigated the characteristics contributing to successful goal attainment of a weight-loss and a non-weight-loss goal simultaneously. Weight-loss and non-weight-loss goals, self-efficacy, persistence, temptations, intergoal interference and facilitation were measured via an online questionnaire (N = 103, Mage = 25.36 ± 6.9, 80% women). Weight-loss self-efficacy, persistence, temptations and intergoal facilitation significantly predicted weight-loss goal attainment. Those who were more successful in attaining both their goals simultaneously had higher self-efficacy and persistence and experienced less temptation towards both goals. This study provides an insight into the characteristics necessary for successful simultaneous management of a weight-loss goal with another goal.
Most choices in the real world follow other choices or judgments. The authors show that a prior choice, which activates and boosts a positive self-concept, subsequently licenses the choice of a more self-indulgent option. The authors propose that licensing can operate by committing to a virtuous act in a preceding choice, which reduces negative self-attributions associated with the purchase of relative luxuries. Five studies demonstrate the proposed licensing effect of a prior commitment to a vir-tuous act on subsequent choice. Consistent with the authors' theory, the preference for an indulgent option diminishes if the licensing task is attributed to an external motivation. The authors also report a mediation analysis in support of their theoretical explanation that the licensing effect operates by providing a temporary boost in the relevant self-concept.
Moderated multiple regression models allow the simple relationship between the dependent variable and an independent variable to depend on the level of another independent variable. The moderated relationship, often referred to as the interaction, is modeled by including a product term as an additional independent variable. Moderated relationships are central to marketing (e.g., Does the effect of promotion on sales depend on the market segment?). Multiple regression models not including a product term are widely used and well understood. The authors argue that researchers have derived from this simpler type of multiple regression several data analysis heuristics that, when inappropriately generalized to moderated multiple regression, can result in faulty interpretations of model coefficients and incorrect statistical analyses, Using theoretical arguments and constructed data sets, the authors describe these heuristics, discuss how they may easily be misapplied, and suggest some good practices for estimating, testing, and interpreting regression models that include moderated relationships.
Baron and Kenny's procedure for determining if an independent variable affects a dependent variable through some mediator is so well known that it is used by authors and requested by reviewers almost reflexively. Many research projects have been terminated early in a research program or later in the review process because the data did not conform to Baron and Kenny's criteria, impeding theoretical development. While the technical literature has disputed some of Baron and Kenny's tests, this literature has not diffused to practicing researchers. We present a nontechnical summary of the flaws in the Baron and Kenny logic, some of which have not been previously noted. We provide a decision tree and a step-by-step procedure for testing mediation, classifying its type, and interpreting the implications of findings for theory building and future research.

This research explores the impact of merely altering the name of a food on dieters’ and nondieters’ evaluations of the food’s healthfulness and taste, as well as consumption. Four studies demonstrate that when a food is identified by a relatively unhealthy name (e.g., pasta), dieters perceive the item to be less healthful and less tasty than do nondieters. When the identical food is assigned a relatively healthy name (e.g., salad), however, dieting tendency has no effect on product evaluations. This effect, which results in differences in actual food consumption, is explained by nondieters’ insensitivity to food cues as well as dieters’ reliance on cues indicating a lack of healthfulness and tendency to employ heuristic information processing when evaluating foods. These findings contribute to the body of literature that explores both individual and contextual factors that influence food evaluation and consumption.
We propose that, in the pursuit of ongoing goals, optimistic expectations of future goal pursuit have greater impact on immediate actions than do less optimistic considerations, such as retrospections on past goal pursuit or less optimistic expectations. Further, we propose that the direction of the impact is determined by the framing of goal pursuit: it motivates goal-congruent actions when goal pursuit is framed as commitment to the goal but motivates goal-incongruent actions when the pursuit is framed as progress toward the goal. Four studies provided consistent support for the proposed hypothesis. (c) 2007 by JOURNAL OF CONSUMER RESEARCH, Inc..
Consumer choices are often driven by multiple goals (e.g., career and family), each of which if viewed in isolation may appear to suggest conflicting choices. This article examines the effect of initial goal pursuit on consumers' interest in pursuing unrelated or even conflicting goals. Four studies were conducted to test whether perceived goal progress hinders the pursuit of the focal goal. These studies demonstrate that in the course of self-regulation progress along one goal liberates people to pursue inconsistent goals. Furthermore, merely planning to make goal progress in the future may facilitate incongruent choice of immediate action. (c) 2005 by JOURNAL OF CONSUMER RESEARCH, Inc..
Restrained and unrestrained subjects were given a "vitamin" (placebo) prior to an ad-lib taste test. Subjects were either told nothing about the placebo or told that previous subjects had reported that the vitamin had made them feel either hungry or full. As predicted, restrained subjects, in two separate studies, behaved in accordance with placebo messages, eating more when given "hungry" messages than when given "full" messages. Unrestrained subjects showed an apparent reverse-placebo effect; they ate less ice cream when given "hungry" information than when given "full" information. Hunger ratings did not parallel eating behavior; possible explanations for this discrepancy are considered. We conclude that unresponsiveness to internal hunger state, and an overreliance on external cognitive cues, characterizes restrained but not unrestrained individuals.
Four studies examined whether people tend to lose confidence in their prospects for success the closer they are to the "moment of truth." Study 1 found that students think they will do better on their midterm exams when asked on the 1st day of class than when asked on the day of the exam. Studies 2 and 4 replicated this finding under controlled conditions. Study 3 demonstrated that the same effect holds retrospectively: People are more confident that they would have performed well at a task long after the time to perform has passed. Data are presented indicating that these results stem from a tendency for people to feel more "accountable" for their assessments, and thus focus less on the causes of success and more on the causes of failure, as the time to perform approaches. Implications for the experience of regret are discussed.
Do self-control situations pit controlled reason against impulsive emotion, or do some emotions support the controlled choice? A pilot study of self-control attitudes found ambivalence between hedonic affect associated with short-term perspectives and self-conscious affect associated with the long term. In Study 1, negative self-conscious affect accompanied higher self-control among delayed-cost dilemmas ("guilty pleasures") but not delayed-benefit dilemmas ("grim necessities"). Study 2 showed that hedonic affect was more accessible than was self-conscious affect, but this difference was less among high self-control dilemmas. In Study 3, unobtrusively primed self-conscious emotion words caused dieters to eat less if the emotions were negative, more if positive. Hedonic positive and negative emotion words had the opposite effect. Self-conscious emotional associations, then, can support self-control if brought to mind before the chance to act.
The self-regulation process often involves breaking an ongoing goal (e.g., keeping in shape) into many individual, constituent subgoals that monitor actual actions (e.g., eating healthy meals, going to the gym). The article examines how pursuing each of these subgoals may influence subsequent goal pursuit. The authors show that when people consider success on a single subgoal, additional actions toward achieving a superordinate goal are seen as substitutes and are less likely to be pursued. In contrast, when people consider their commitment to a superordinate goal on the basis of initial success on a subgoal, additional actions toward achieving that goal may seem to be complementary and more likely to be pursued. These predictions were tested in four studies that explored the conditions under which subgoals attainment have a counterproductive versus favorable effect on further pursuit of similar actions.

The authors propose that people use 2 routes in justifying self-gratification: 1st through hard work or excellence (entitlement) and the 2nd through the attainment of vices without depleting income. This framework was tested using real tasks and choices adopted from prior research on self-control. The results indicate that (a) higher effort and (bogus) excellence feedback increase preferences for vice rewards, but these effects are reversed or attenuated when the interchangeability of effort and income is implied; (b) willingness to pay in effort is greater for vices than virtues, but willingness to pay in income is higher for virtues; and (c) these effects are magnified among individuals with stronger (chronic or manipulated) guilt. The authors discuss the ability of the justification routes to explain the findings of prior self-control research.
Although frequency programs (FPs) have become ubiquitous in the marketplace and a key marketing-mix tool for promoting customer relationship and loyalty, little is known about the factors that determine how such programs are evaluated by consumers. The authors investigate the impact of the level of effort participants must invest to obtain the reward on the types of rewards they prefer and, consequently, on the decision to join the FP. In particular, the authors propose that higher required effort shifts consumer preferences from necessity to luxury rewards, because higher efforts reduce the guilt that is often associated with choosing luxuries over necessities. A series of studies with approximately 3100 consumers demonstrated that (1) higher program requirements shift preferences in favor of luxury rewards, (2) this effect is also observed when consumers choose between luxury and necessity rewards (of the same value) that they themselves proposed, and (3) the effect of program requirements on reward preferences is stronger among consumers who tend to feel guilty about luxury consumption and among those for whom the effort is invested in the context of work rather than pleasure. In addition, contrary to an alternative explanation based on the notion that higher requirements signal higher value of luxury rewards, the authors show that (1) when the program requirements are held constant but the individual consumer's effort is higher, the shift in preference toward luxuries is still observed and (2) increasing the monetary cost of participating in the FP decreases consumer preferences for luxury rewards. The authors discuss the theoretical implications of this research and the practical implications with respect to the design, targeting, and promotion of FPs.
Volitional behaviors can be construed as “work” (extrinsically motivated) or as “fun” (intrinsically motivated). When volitional behaviors are construed as an obligation to work, completing the behavior depletes a consumer, and subsequent self-control becomes more difficult. When volitional behaviors are construed as an opportunity to have fun, completing the behavior vitalizes a consumer, and subsequent self-control becomes easier. Six studies show how individual differences and contextual factors influence the construal of a task, the motivation for completing it, and subsequent regulatory behavior.
The purpose of this research was to empirically develop the Cognitive Behavioral Dieting Scale (CBDS), a measure of current dieting.
The first study involved item generation and a procedure to boost internal consistency while reducing scale length. Study 2 involved a factor analysis and measures of scale reliability. The third study evaluated the ability of the CBDS to predict calorie intake and negative calorie balance from a 24-hr diet recall. Study 4 evaluated construct validity by comparing the CBDS to dietary restraint, body image, and health behavior self-efficacy.
The CBDS is a 14-item scale which measures current dieting behavior and related thoughts within the past 2 weeks. Internal consistency was alpha = .95 and 2-day test-retest reliability was r = .95. This scale provides a method for operationalizing dieting, provides a construct that is different from restraint, and assess dieting behavior on a continuum. Additionally, this scale was able to predict calorie intake and negative calorie balance above and beyond the predictive ability of physical variables (i.e., body mass index BMI] and exercise calories). An additional study of construct validity showed the CBDS was related to poor body image esteem and dietary restraint, but minimally related to healthy eating self-efficacy.
In conclusion, the CBDS shows promise as a valid and reliable measure of dieting behavior. This scale should have utility in future research on how current dieting relates to eating disorders, dietary restraint, and obesity.
Past research has shown that strong emotional or motivational states can cause normally restrained eaters to overeat. In this article it is argued that simple cognitive load can also disinhibit eating by restrained eaters. Two studies examined this disinhibition effect. In Study 1, restrained and unrestrained eaters were given the opportunity to consume high-calorie food while performing either a high cognitive-load or low cognitive-load task. Restrained eaters consumed more food when under high cognitive load than when under low cognitive load; unrestrained eaters showed the opposite pattern. Study 2 replicated the disinhibition effect and ruled out stress, diminished awareness of food consumption, and ironic rebound as probable mediators. Results suggest that cognitive load may disinhibit consumption by preventing restrained eaters from monitoring the dietary consequences of their eating behavior. Implications for theories of self-regulation are discussed.
Three experiments supported the hypothesis that people are more willing to express attitudes that could be viewed as prejudiced when their past behavior has established their credentials as nonprejudiced persons. In Study 1, participants given the opportunity to disagree with blatantly sexist statements were later more willing to favor a man for a stereotypically male job. In Study 2, participants who first had the opportunity to select a member of a stereotyped group (a woman or an African American) for a category-neutral job were more likely to reject a member of that group for a job stereotypically suited for majority members. In Study 3, participants who had established credentials as nonprejudiced persons revealed a greater willingness to express a politically incorrect opinion even when the audience was unaware of their credentials. The general conditions under which people feel licensed to act on illicit motives are discussed.
This study examined the effect of anticipated food deprivation on intake in restrained and unrestrained eaters. Participants were randomly assigned to a diet condition, in which they expected to diet for a week, or to a control (no-diet) condition. Immediately after being assigned to a condition, participants completed a taste-rating task in which food consumption was measured. Restrained eaters in the diet condition consumed significantly more food than did restrained eaters in the no-diet condition or unrestrained eaters in either condition. Unrestrained eaters consumed the same amount regardless of condition. These results confirm that merely planning to go on a diet can trigger overeating in restrained eaters, reflecting the dynamic connection between dieting and overeating.
Previous research has shown that exposure to food cues increases eating, especially in restrained eaters. The present study attempted to determine whether this elevated consumption reflects a general desire to eat in response to food cues, or specific desire/craving for the cued food. Restrained and unrestrained eaters were exposed to the smell of either pizza, cookies, or no smell for 10 minutes, were asked to write their thoughts (corresponding to the smell cue) about pizza, cookies or in general, and were then presented with either pizza or cookies to 'taste and rate'. Results indicated that restrained eaters are more responsive than are unrestrained eaters to pre-eating exposure to smell and thought cues, eating significantly more after such cues. An interaction with food type, however, indicated that restrained eaters ate more only when the food presented to eat was the same as the prior food cues. Self-reported desire to eat, liking, and craving for a particular food increased somewhat for restrained eaters after exposure to the smell and thought of that food. Restrained eaters' intake of a food that differed from the pre-eating food cues did not differ from their intake following no prior exposure to food cues. Restrained eaters thus showed a highly specific response to exposure to food cues.
Based on Wegner's Ironic Processing Theory, this study examines the effects of suppressing eating-related thoughts in a sample of 77 female students. A distinction was made between disinhibited restrainers (high dietary restraint/high disinhibition), inhibited restrainers (high dietary restraint/low disinhibition) and low restrainers. Results indicate that disinhibited restrainers used thought suppression more often and were the only group to show a rebound effect for eating-related thoughts after suppression. No effects of suppression on willingness and desire to eat emerged. Hence, thought suppression may be counterproductive at least for a subgroup of restrainers and may fuel eating-related preoccupations. More research is required to evaluate effects on eating behaviour.
