Expresión Génica

El “food craving” (FC) es un deseo incontrolable por ingerir alimentos en específico, se activa durante la fase de abstinencia de alimentos azucarados, salados y grasos. Se ha encontrado que se relaciona con obesi-dad (OB) y con trastornos del comportamiento de la alimentación, además de ser un factor negativo para la adherencia al tratamiento de la OB. Los Food Cravings Questionnaires Trait (T-rasgo) y State (S-estado) son instrumentos validados, que miden rasgo-estado, son confiables, y con consistencia interna alta (ɑ>0,90). El objetivo de esta investigación fue analizar diferencias entre sujetos normopeso (NP) y OB, en puntajes del FCQ Trait y State, y en la expre-sión génica de DRD2, TAS1R2, TAS1R3 y el TAS2R43. Se trató de un estudio correlacional, transversal de casos y controles, muestreo no probabilístico, y a conveniencia; con 20 sujetos NP y 20 sujetos OB, de ambos sexos entre 18-45 años, residentes de la Ciudad de México y del Estado de México. Se evaluaron el IMC, el FC y la expresión génica. Se encontraron diferencias significativas (p<0,05) en expresión relativa del TAS1R2, y correlación positiva entre el FCQ y expresión del TAS1R2 en OB; también se encontró que el FCQ-T y FCQ-S pre-dicen la expresión génica de TAS1R2 y TAS2R43 en hombres, y en mujeres del TAS1R2, TAS2R43 y el DRD2. Esta investigación ayuda a comprender la asocia-ción del FC, con el receptor del gusto dulce (TAS1R2), evidenciando el enlace con componentes moleculares, y su posible relación con adicción a alimentos azucarados.

Background: Overweight people have been revealed to have poor cognitive flexibility. Cognitive flexibility reflects proactive and reactive control abilities. However, the impairment had not been explicitly positioned at the cognitive stage. Therefore, this study provides increased support for impairment of cognitive flexibility due to overweight. Method: The study included 34 overweight and 35 normal-weight participants. They were required to complete the food and flower target AX-continuous performance test (AX–CPT), including the resting-state fMRI and cue-triggered food craving subscales. We compared the performance difference between the two tasks. Furthermore, we investigated whether the cue-triggered food cravings and the corresponding brain regions mediated the effect of overweight on the two control mechanisms. Result: Significant differences were found only in the food target AX-CPT task, where overweight participants performed worse. Cue-triggered food cravings mediated this relationship. Additionally, we found that the brain regions associated with cue-triggered food cravings (bilateral SFG) can completely mediate the relationship between BMI and the z-value of the fat mass index and sensitivity to proactive control. Conclusion: In the food target task, overweight participants performed worse in both control mechanisms. Moreover, we also revealed the potential mechanism by which being overweight might affect the two control mechanisms through cue-triggered food cravings.

Previous studies indicate that eating behaviours and food cravings are associated with increased BMI and obesity. However, the interaction between these behaviours and other variables such as age, sex, BMI and genetics is complex. This study aimed to investigate the relationships between eating behaviours and food cravings, and to examine the influence of age, sex, body mass index (BMI) and fat mass and obesity-associated (FTO) genotype on these relationships. A total of 475 participants (252 female, 223 male, BMI: 25.82 ± 6.14 kg/m2, age: 30.65 ± 14.20 years) completed the revised 18-question version of the Three Factor Eating Questionnaire (TFEQ-R18) to assess cognitive restraint, uncontrolled eating and emotional eating, and the Food Cravings Inventory (FCI) to assess cravings for fatty food, sweet food, carbohydrates and fast food. DNA samples were genotyped for the rs9939609 polymorphism in the obesity-linked gene FTO. Questionnaire data was analysed for associations between the TFEQ-R18 and FCI subscales for the whole study group, and the group divided by sex, genotype and age (≤25 years versus >25 years). Finally, mediation analysis was used to explore the relationships between BMI, cognitive restraint and food cravings. FTO AA + AT genotype was associated with increased BMI, but not with differences in eating behavior scores or food craving scores; age was associated with increased BMI and decreases in food craving scores in which this effect was stronger in women compared to men. Increased cognitive restraint was associated with decreased food craving scores in the ≤25 years group. Mediation analysis demonstrated that in this group the association between BMI and reduced food cravings was mediated by cognitive restraint indicating that in this age group individuals use cognitive restraint to control their food cravings. The positive correlation between age and BMI confirms previous results but the findings of this study show that age, sex, FTO genotype and BMI have an influence on the relationships between eating behaviours and food cravings and that these variables interact.

Overeating behavior is supposedly a major contributing factor to weight gain and obesity. Binge eating disorder (BED) with reoccurring episodes of excessive overeating is strongly associated with obesity. Learning models of overeating behavior and BED assume that mere confrontation with food leads to a conditioned response that is experienced as food craving. Accordingly, individuals with obesity and BED were shown to have high trait food cravings. To date, little is known about differences in state food cravings and cue reactivity at the sight of palatable food in individuals with obesity and BED compared to individuals with obesity without BED. Therefore, the aim of our study was to examine differences in cue-induced, state and trait food cravings in people with obesity with and without BED. We found that all aspects of food cravings were more prevalent in individuals with obesity and BED than in individuals without BED. By implementing a food cue reactivity paradigm, our results show that individuals with obesity with BED have more cue-induced cravings than individuals with obesity without BED. Moreover, these cue-induced cravings in individuals with obesity and BED were highest for high-fat and high-sugar foods as opposed to low-calorie foods. Thus, our results emphasize the role of increased cue reactivity and craving at the sight of palatable foods in individuals with obesity and BED. Hence, our findings support etiological models of conditioned binge eating and are in line with interventions targeting cue reactivity in BED.

Dysphoric Mood

Cravings are hedonic responses to food, characterised by their intensity and their specificity. Food cravings are extremely common, reported by the majority of young adults. They are closely associated with liking but not synonymous with increased intake. Structured interviews and prospective incident accounts of food cravings have succeeded in revealing a richness of information about their character, their antecedents and their consequences. In addition, laboratory investigations are adding to what is being learned from field and clinical studies. Taking dieting as an example of an assumed influence on food craving, the outcomes of cross-sectional studies are mixed and unconvincing. Prospective and experimental research shows a clearer relationship. Dieting or restrained eating generally increase the likelihood of food craving while fasting makes craving, like hunger, diminish. Attempted restriction or deprivation of a particular food is associated with an increase in craving for the unavailable food. This relationship suggests a variety of underlying cognitive, conditioning and emotional processes, of which ironic cognitive processes, conditioned cue reactivity and dysphoric mood are prominent. Food cravings may also be self-attributions, accounting for why a highly-palatable but self-restricted food is (over-)consumed. Overall, the popularised account of cravings as elicited by specific nutritional need is having to give way to a more subtle and complex appreciation of human eating behaviour.

Baseline Bmi

Neural patterns associated with viewing energy-dense foods can predict changes in eating-related outcomes. However, most research on this topic is limited to one follow-up time point, and single outcome measures. The present study seeks to add to that literature by employing a more refined assessment of food craving and consumption outcomes along with a more detailed neurobiological model of behavior change over several time points. Here, a community sample of 88 individuals (age: M = 39.17, SD = 3.47; baseline BMI: M = 31.5, SD = 3.9, range 24-42) with higher body mass index (BMI) performed a food craving reactivity and regulation task while undergoing functional magnetic resonance imaging. At that time—and 1 month, 3 months, and 6 months later—participants reported craving for and consumption of healthy and unhealthy foods via the Food Craving Inventory (FCI) and ASA24 (N at 6 months = 52-55 depending on the measure). A priori hypotheses that brain activity associated with both viewing and regulating personally-desired unhealthy, energy-dense foods would be associated with self-reported craving for and consumption of unhealthy foods at baseline were not supported by the data. Instead, regression models controlling for age, sex, and BMI demonstrated that brain activity across several regions measured while individuals were regulating their desires for unhealthy food was associated with the self-reported craving for and consumption of healthy food. The hypothesis that vmPFC activity would predict patterns of healthier eating was also not supported. Instead, linear mixed models controlling for baseline age and sex, as well as changes in BMI, revealed that more regulation-related activity in the dlPFC, dACC, IFG, and vmPFC at baseline predicted decreases in the craving for and consumption of healthy foods over the course of 6 months.

Perceived Availability

Purpose This paper aims to explore the influence of four types of imagery stimuli (i.e. visual, olfactory, gustatory and auditory) on food craving intensity based on the Elaborated Intrusion theory and the central role of mental imagery in the food craving experience. The roles of overall perception of sensory imagery attributes and perceived availability in moderating this process were also tested. The aim is to extract the positive aspects of food cravings by increasing them and shifting them toward healthy foods. Design/methodology/approach In an online experiment, 314 participants were randomly primed with each imagery condition. After being exposed to either healthy or unhealthy food pictures, participants completed a questionnaire measuring their craving state, trait food craving, imaging ability, BMI, dietary restraint, hunger and mood. At the end, the impact of food craving intensity on marketing outcomes (i.e. willingness to pay, price sensitivity and food intake) were tested. Findings As predicted, visual imagery was found to be the strongest stimulus inducing food craving followed by olfactory, gustatory and auditory stimuli. Furthermore, the results indicate that perceived availability of food is the only important variable moderating this process. Additionally, the results show that hunger makes consumers more susceptible to food cravings than mood. Moreover, food craving intensity showed significant impact on the two marketing outcomes: willingness to pay and food intake. Research limitations/implications First, the authors used a cheeseburger as unhealthy food and salad as healthy food, future studies can increase the generalizability of the findings by using other types of food. Second, physiological and psychological disorders should be considered and studied as influential factors on food cravings in future studies. Third, future studies should include some behavioral measures besides the analysis of state and trait craving. Fourth, although the main objective of this study was to compare the effect of different imagery stimuli on consumers’ food craving, there was no control (no-stimulus) condition. Practical implications Marketing strategists may benefit from the fact that encouraging consumers to visualize some specific type of food product along with informing them about its availability will elevate their craving for that food product. Hence, using this strategy in shopping environments could be beneficial. In the context of improving people’s diet, our results showed that encouraging people to visualize healthy foods (e.g. fruits and vegetables) might be more helpful than priming them with the benefits of eating healthy. Originality/value There has been a recent enthusiastic interest in identifying the role of food related mental imagery and stimuli in consumers’ decision making and their final consumption (Christian et al., 2016). Nevertheless, very few studies in marketing have paid attention to these underpinning stimuli driving food craving and the significant influence of this food craving phenomenon on marketing outcomes.
