Orofacial reactivity to the sight and smell of Food stimuli. Evidence for anticipatory liking related to Food reward cues in overweight children.
Appetite, 2012Co-Authors: Robert Soussignan, Benoist Schaal, Véronique Boulanger, Marie Gaillet, Tao JiangAbstract:Whether Food liking may be a risk factor of overconsumption and overweight/obesity remains a controversial issue. So far, most studies used subjective reports to assess consummatory behavior, approaches that might overlook subtle or implicit hedonic changes to sensory properties of Foods. Therefore, we used a cue-exposure approach by recording different measures of hedonic processes (orofacial reactivity, self-rated pleasantness, Food preference) in 6-11 years old overweight (n=20) and normal-weight (n=20) children. Children were exposed to the smell and sight of High and low-Energy density Food stimuli and to non-Food stimuli during pre- and post-prandial states. Their facial and verbal responses were videotaped and parent's reports of children's eating styles and appetitive traits were collected using the Children's Eating Behavior Questionnaire (CEBQ). Results showed that orofacial reactivity, as an objective measure of anticipatory liking, was more discriminative than self reports, with overweight children displaying more lip sucking than normal-weight children when exposed to High Energy Food pictures and to Food odorants. Orofacial reactivity to Food cues was also associated with BMI and children's eating styles (Food responsiveness, emotional overeating, and desire to drink). Finally, overweight children classified more frequently non-Food odorants as members of the Food category during the pre-prandial state than during the post-prandial state, suggesting a possible influence of affective/motivational bias on odor categorization. Our findings suggest that orofacial responsiveness may be relevant to assess the sensitivity to Energy-dense Food reward cues in overweight children and for signaling, as an index of anticipatory liking, a potential risk for the development of overweight/obesity.

Pleasure for visual and olfactory stimuli evoking Energy-dense Foods is decreased in anorexia nervosa.
Psychiatry Research, 2010Co-Authors: Tao Jiang, Robert Soussignan, Daniel Rigaud, Benoist SchaalAbstract:Although patients with anorexia nervosa have been suggested to be anhedonic, few experiments have directly measured their sensory pleasure for a range of Food and non-Food stimuli. This study aimed to examine whether restrictive anorexia nervosa (AN-R) patients displayed: i) a generalized decline in sensory pleasure or only in Food-related sensory pleasure; ii) a modification of hedonic responses to Food cues (liking) and of the desire to eat Foods (wanting) as a function of their motivational state (hunger vs. satiety) and Energy density of Foods (High vs. low). Forty-six female participants (AN-R n=17; healthy controls (HC) n=29) reported before/after lunch their pleasure for pictures/odorants representing Foods of different Energy density and non-Food objects. They also reported their desire to eat the Foods evoked by the sensory stimuli, and completed the Physical Anhedonia Scale and the Beck Depression Inventory. AN-R and HC participants did not differ on liking ratings when exposed to low Energy-density Food or to non-Food stimuli. The two groups also had similar physical anhedonia scores. However, compared to HC, AN-R reported lower liking ratings for High Energy Food pictures regardless of their motivational state. Olfactory pleasure was reduced only during the pre-prandial state in the AN-R group. The wanting ratings showed a distinct pattern since AN-R participants reported less desire to eat the Foods representing both low and High Energy densities, but the effect was restricted to the pre-prandial state. Taken together these results reflect more the influence of core symptoms in anorexia nervosa (fear of gaining weight) than an overall inability to experience pleasure.

Neural correlates of restrained eaters' High susceptibility to Food cues: An fMRI study.
Neuroscience letters, 2016Co-Authors: Yu Wang, Debo Dong, Jackson Todd, Zhou Yang, Hong ChenAbstract:Many studies have reported that specific susceptibility to Food cues plays an important role in disordered eating behavior. However, whether restraint status modulates the neural bases of attentional bias to different types of Food cues remains unknown. Thus, functional magnetic resonance imaging (fMRI) was conducted in individuals (12 restraint eaters, 12 unrestraint eaters) exposed to High/low-Energy Food and neutral images while performing a two-choice oddball task. The results indicated that restrained eaters responded more quickly to High-Energy Food images than to neutral and low-Energy Food images. More notably, compared with unrestrained eaters, restrained eaters showed faster reaction times, hyper-activation in a much wider array of reward (e.g., insula/orbitofrontal cortex), attention (superior frontal gyrus) and visual processing (e.g., superior temporal gyrus) regions, and hypo-activation in cognitive control areas (e.g., anterior cingulate) in response to High-Energy Food cues. Furthermore, among restrained eaters, the longest reaction times were found for low-Energy Food images, and activation of the attention and visual-related cortex (e.g., superior parietal gyrus) in the low-neutral contrast condition was significantly stronger than in unrestrained eaters. These findings contribute to our understanding of susceptibility to Food cues: in addition to the special sensitivity (attentional bias) to High-Energy Food images, restrained eaters may also be more sensitive (allocate more attentional resources) to low-Energy Food images. These potential neural bases of restrained eaters may help clarify why dieting to lose or maintain weight is so often unsuccessful.

Inhibition ability of Food cues between successful and unsuccessful restrained eaters: a two-choice oddball task.
PloS one, 2015Co-Authors: Fanchang Kong, Yan Zhang, Hong ChenAbstract:Background Previous studies have presented mixed findings on the inhibition ability in restrained eaters (REs) due to the limited amount of neural evidence and limitations of behavioral measures. The current study explores the neural correlations of the specific inhibition ability among successful restrained eaters (S-REs), unsuccessful restrained eaters (US-REs), and unrestrained eaters (UREs). Methodology and Principal Findings Three groups of females (with 13 participants in each group) completed a two-choice Oddball task, while the event-related potentials (ERPs) are recorded synchronously. Results indicate that S-REs showed inhibition deficit in processing High-Energy Food cues whereas US-REs show inhibition deficit in processing both low- and High-Energy Food cues. Conclusion Results indicate that S-REs and US-REs differ in terms of specific inhibition ability and that enhanced inhibition is essential to a successful diet.

Neural reactivity to visual Food stimuli is reduced in some areas of the brain during evening hours compared to morning hours: an fMRI study in women.
Brain imaging and behavior, 2015Co-Authors: Travis D. Masterson, C. Brock Kirwan, Lance E. Davidson, James D. LecheminantAbstract:The extent that neural responsiveness to visual Food stimuli is influenced by time of day is not well examined. Using a crossover design, 15 healthy women were scanned using fMRI while presented with low- and High-Energy pictures of Food, once in the morning (6:30–8:30 am) and once in the evening (5:00–7:00 pm). Diets were identical on both days of the fMRI scans and were verified using weighed Food records. Visual analog scales were used to record subjective perception of hunger and preoccupation with Food prior to each fMRI scan. Six areas of the brain showed lower activation in the evening to both High- and low-Energy Foods, including structures in reward pathways (P < 0.05). Nine brain regions showed significantly Higher activation for High-Energy Foods compared to low-Energy Foods (P < 0.05). High-Energy Food stimuli tended to produce greater fMRI responses than low-Energy Food stimuli in specific areas of the brain, regardless of time of day. However, evening scans showed a lower response to both low- and High-Energy Food pictures in some areas of the brain. Subjectively, participants reported no difference in hunger by time of day (F = 1.84, P = 0.19), but reported they could eat more (F = 4.83, P = 0.04) and were more preoccupied with thoughts of Food (F = 5.51, P = 0.03) in the evening compared to the morning. These data underscore the role that time of day may have on neural responses to Food stimuli. These results may also have clinical implications for fMRI measurement in order to prevent a time of day bias.

Neural Reactivity to Visual Food Stimuli in the Morning and Evening: An fMRI Study in Women
2014Co-Authors: Travis D. MastersonAbstract:Neural Reactivity to Visual Food Stimuli in the Morning and Evening: an fMRI Study in Women Travis Masterson Department of Exercise Sciences, BYU Master of Science Background: Visual Food stimuli have been shown to influence desire to eat and may influence overall Energy intake. The purpose of this study was to determine the influence, if any, that time of day has on the neural response to visual Food stimuli, as measured by functional magnetic resonance imaging (fMRI). Methods: Using a crossover design, 15 healthy women were scanned using fMRI while presented with lowand High-Energy pictures of Food, once in the morning (6:30–8:30 am) and once in the evening (5:00–7:00 pm). Diets were identical on both days of the fMRI scans and were verified using weighed Food records. Pictures used were based on the work of Sweet et al. (2012). Visual analog scales were used to record subjective perception of hunger and preoccupation with Food prior to each fMRI scan. Results: Nine brain regions showed significantly Higher activation for High Energy stimuli compared to low Energy stimuli (p < 0.05). Six areas of the brain showed lower activation in the evening to both High and low Energy stimuli including parts of some reward pathways (p < 0.05). Subjectively, participants reported no difference in hunger by time of day (F(1, 14) = 1.84, p = 0.19), but felt they could eat more (F = 4.83, p = 0.04) and were more preoccupied with thoughts of Food (F = 5.51, p = 0.03) in the evening compared to the morning. Conclusions: High Energy Food stimuli tended to produce greater fMRI responses than low Energy Foods in specific areas of the brain, regardless of time of day. However, evening scans showed a lower response to both Food categories in some areas of the brain compared to the morning. These data may have clinical implications for fMRI measurement and practical implications for sensitivity to Food cues and eating behavior.
