Temporal Self-Regulation theory (TST) aims to address the intention-behavior gap; however, its applicability to eating behavior remains insufficiently validated. The objective of this review was to assess whether the constructs of TST are associated with eating behavior. A comprehensive literature review was conducted in December 2024, utilizing the databases Web of Science, PsycINFO, CINAHL, and EMBASE. A total of 21 articles, encompassing 7913 participants, were identified. Meta-analyses were performed to examine the associations between the theoretical constructs and eating behaviors. The findings indicated that intention (ES(z) = 0.50, 95% CI: 0.33, 0.68, P < 0.001; pooled r = 0.46), behavioral prepotency (ES(z) = 0.68, 95% CI: 0.31, 1.05, P < 0.001; pooled r = 0.59), and self-regulation capacity (ES(z) = 0.37, 95% CI: 0.25, 0.49, P < 0.001; pooled r = 0.35) are significantly associated with healthy eating behaviors. For unhealthy eating behaviors, significant associations were demonstrated only with intention (ES(z) = 0.47, 95% CI: 0.01, 0.93, P = 0.04; pooled r = 0.44) and behavioral prepotency (ES(z) = 0.39, 95% CI: 0.25, 0.53, P < 0.001; pooled r = 0.37). These findings suggest that TST is applicable to eating behaviors. In particular, future interventions should be grounded in scientific theory, with a focus on optimizing intention, behavioral prepotency, and self-regulation capacity, while also considering the cultural context and individual needs of the target population. These efforts are essential for achieving global dietary health goals and will contribute significantly to preventing the occurrence of diet-related noncommunicable diseases.

Insufficient food provision and malnutrition are features of neglect and are reasons children are taken into care. Subsequent eating difficulties may have long-term negative physical and mental health impact. Literature from various countries indicates patterns of over- and under-consumption, hoarding and stealing food, and consumption of contaminated or non-food (pica) sources in care-experienced children, but no studies have examined these patterns in the UK.

This study recruited parents and carers of care-experienced children (CE, n = 105, Age M = 9.24 years, 62% male), comparing them with birth parents living with their child/ren (NCE, n = 103, Age M = 7.95 years, 43% male) on problematic eating measures. Participants were also asked open-ended questions about challenges and enjoyment of mealtimes.

The CE group reported higher levels of problematic eating, dietary concern and food maintenance in their children than the other group, with medium-large effect sizes. Number of Adverse Childhood Events experienced was positively associated with these factors. Through Template Analysis, the CE group identified food consumption, disruptive behaviour, negative communication and food rejection/aversion as challenges. The comparison group reported similar challenges, with lower levels of behavioural extremes. Time together, creating a positive environment and exploring/enjoying new food were identified as enjoyable mealtime aspects in both groups. The CE group placed more emphasis on creating a nurturing and calm atmosphere.

This is the first study in the UK to provide a comprehensive picture of eating and mealtime behaviours in care-experienced children. Insights into the specific challenges that parents and carers face in this context can assist intervention development.

食物供应不足和营养不良是被忽视的特征，也是儿童被送往照料机构的原因。随后出现的饮食困难可能会对身心健康产生长期的负面影响。来自不同国家的文献表明，曾受照料的儿童会出现摄入过多或过少、囤积和偷窃食物以及食用受污染或非食物（pica）等情况，但在英国还没有研究对这些情况进行过调查。本研究招募了有照料经历儿童的父母和照料者（CE，人数=105，年龄M=9.24岁，62%为男性），并将他们与与子女/儿童生活在一起的亲生父母（NCE，人数=103，年龄M=7.95岁，43%为男性）在饮食问题测量方面进行了比较。参与者还被问及有关进餐时间的挑战和乐趣的开放式问题。与其他组相比，CE 组报告的儿童饮食问题、饮食关注和食物维持水平较高，影响大小中等偏大。经历的儿童不良事件数量与这些因素呈正相关。通过模板分析，CE 组将食物消耗、破坏性行为、消极沟通和拒绝/厌恶食物视为挑战。对比组报告了类似的挑战，但极端行为的水平较低。两组都认为共餐时间、创造积极的环境和探索/享受新食物是愉快的用餐时间。CE 组则更重视营造温馨平静的氛围。这是英国第一项全面了解有护理经历儿童的进食和用餐行为的研究。了解父母和照顾者在这种情况下面临的具体挑战有助于干预措施的制定。

Enabling people to reduce their consumption of unhealthy appetitive products can improve their health. Over the last decades, progress has been made by uncovering new ways to change behavior toward appetitive products without feedback incentives (e.g., reward or punishment, as in feedback-driven reinforcement learning), but instead by cueing motor responses (e.g., go vs. no go) toward these products in cognitive training tasks. However, it is unclear how this nonreinforced learning compares to reinforcement learning. Moreover, recent work on reinforcement learning has uncovered a basic learning mechanism, the action–valence asymmetry, which points to the possibility that reward and punishment learning may not always outperform learning without any external reinforcement. Here, we report two well-powered preregistered experiments (experiment 1a: N = 72; experiment 1b: N = 81) that examined when reinforcement learning outperforms nonreinforced learning in modifying people's preferences for food. Our findings show that reinforcement learning notably surpasses nonreinforced learning, but only when active responses (go) are rewarded, and inactions (no-go) are reinforced by avoiding punishments. These results shed light on interventions that combine rewards and punishments to facilitate changes in food preferences.

Children often consume not enough vegetables, and the overall quality of their diet is concerning. This research investigates the intergenerational transmission of the Unhealthy = Tasty Intuition (UTI) from parents to children and its role in shaping children's vegetable consumption. In two studies involving both children and their parents, we test whether parental UTI beliefs predict their children's UTI beliefs. Our findings demonstrate a positive relationship between parental and child UTI beliefs, which, in turn, are negatively associated with children's vegetable consumption. In the second study, we explore which parental feeding practices can help explain the socialization of the UTI. Our research contributes to the understanding of how children's food beliefs and consumption are socialized. Recognizing the impact of the UTI on children's dietary consumption provides valuable insights for developing interventions and policies aimed at promoting healthier eating habits among children. By addressing the intergenerational transmission of the UTI, we can take significant steps toward mitigating childhood obesity and its associated health risks.

Functional meat products to reduce appetite is a feasible approach to decreasing meat consumption, especially in the current global pandemic of overweight and sustainability issues in meat production. The meat itself is highly satiating because of its high protein content. Dietary fibre and plant protein, both naturally occurring macromolecular compounds with appetite-suppressant properties, work synergistically with the meat itself to create a feeling of fullness. Dietary fibre consumption induces satiety by improving structural complexity and chewing time. Increasing protein content improves the volume and texture of the product. The overall effect on appetite varies widely with ingredient and meat product types. By-products, mycoproteins, and insects have the potential to generate functional and sustainable meat products. The incorporation of functional ingredients improves the yield and textural complexity of meat products, albeit at the expense of sensory properties. The complex interactions among food structure, texture, oral processing, and satiety/palatability warrant additional study to inform the design of meat products that maximise the contribution to appetite control. This review aims to provide an overview of the types of ingredients used in the preparation of functional meat products and their effect on controlling appetite.

降低食欲的功能性肉类产品是减少肉类消费的一种可行方法，尤其是在当前全球普遍超重和肉类生产可持续发展问题的情况下。由于蛋白质含量高，肉类本身具有很强的饱腹感。膳食纤维和植物蛋白都是天然存在的大分子化合物，具有抑制食欲的特性，它们与肉类本身协同作用，产生饱腹感。膳食纤维通过改善结构的复杂性和咀嚼时间来诱发饱腹感。增加蛋白质含量可改善产品的体积和质地。对食欲的总体影响因配料和肉制品种类的不同而有很大差异。副产品、霉菌蛋白和昆虫具有生产功能性和可持续肉制品的潜力。功能性配料的加入提高了肉制品的产量和质地的复杂性，但同时也牺牲了感官特性。食品结构、质地、口腔加工和饱腹感/适口性之间复杂的相互作用需要更多的研究，以便为设计最大限度地促进食欲控制的肉类产品提供信息。本综述旨在概述用于制备功能性肉制品的配料类型及其对控制食欲的影响。

Aims

To investigate the phenomenon of picky eating among children and its association with early feeding practices, including feeding patterns during infancy, introduction of solid food, and weaning age. We also examined the association of picky eating with negative parental attitudes toward eating behaviors and the weight status of children.

Methods

This cross-sectional study included 365 preschool children (ages 2–6)-mother dyads living in Kuwait. To identify picky eaters, trained dietitians administered a set of questionnaires to the mothers, including one that assessed parental attitudes toward their children's eating behaviors. The participating children's weights and heights were recorded, and their weight status was determined using the WHO growth charts.

Results

Of the children, 35.6% were identified as picky eaters. Picky eating was significantly associated with the mother's negative attitudes toward her child's eating behavior, reduced Height-for-age z-scores (HAZ), and reduced BMI-for-age z-scores (BAZ). No association was found between the type of feeding and age at which solid food was introduced.

Conclusion

Our findings highlight a significant association between maternal attitudes and picky eating. Mothers—especially those displaying consistent worry regarding their children's eating habits —were more prone to having picky eating children and therefore harbored greater concerns regarding their growth deficits. However, the cross-sectional design precludes determining causality. Future research is needed to explore potential bi-directional influences. Our findings can inform the development of effective strategies and interventions to address picky eating behaviors and promote healthier eating habits among Kuwaiti children, thereby enhancing their nutritional status and overall well-being.

Prior research has investigated whether the capacity of individuals with anorexia nervosa (AN) to forgo food rewards in their pursuit of thinness may manifest as more delayed gratification in delay discounting tasks, but results have been mixed. In a previous study examining mouse-cursor movement trajectories during a delay discounting task, underweight patients with AN made similar decisions relative to healthy controls, but displayed more stable levels of decision-making conflict. Here, we employed the exact same methods to test whether these changes persist after long-term weight restoration. We recorded mouse-cursor trajectories during a delay discounting task in 45 female adolescents and young women weight-restored from AN (wrAN) and 90 female healthy controls (HC). We examined group differences in deviations from a direct choice path as a measure of decision-making conflict strength and moderation effects of associated predictors (e.g., choice difficulty). No group differences were detected in either delay discounting parameters or mouse cursor trajectories, and the effect of the aforementioned predictors on deviations was reduced in wrAN relative to HC. Persisting reduced variability of conflict strength across decisions might reflect a cognitive-behavioral trait marker of AN. This may enable individuals with AN to pursue long-term (body-weight) goals, because particularly conflicting choices may not be experienced as such.

This may enable individuals with AN to pursue long-term (body-weight) goals, because particularly conflicting choices may not be experienced as such.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"209 ","pages":"Article 107934"},"PeriodicalIF":4.6,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In today's "obesogenic" environment, Pavlovian cues signaling the availability of high-calorie foods may elicit strong expectancies of eating and food cravings. Such cue-elicited appetitive responses, collectively referred to as food cue reactivity, may foster overeating and weight gain. Moreover, food-related cues may also elicit instrumental actions aimed at obtaining those foods via Pavlovian-to-Instrumental Transfer (PIT). This study compared extinction and counterconditioning in reducing food cue reactivity, measured by outcome expectancies, craving, and liking, as well as in decreasing outcome-specific PIT. We used a three-phase PIT paradigm: In the first two phases, participants learned Pavlovian associations between two conditioned stimuli (CSs+) and two food outcomes, and instrumental associations between two responses and the same outcomes. An additional stimulus was never paired with food outcomes (CS-). Participants then underwent either extinction or counterconditioning for one CS+ while the other CS+ remained unchanged, or received no additional learning (control). In the test phase, instrumental responding was measured in the presence and absence of Pavlovian stimuli. In all phases, we measured outcome expectancies, craving and liking of the Pavlovian stimuli. Both extinction and counterconditioning reduced cue-elicited outcome expectancies, but only counterconditioning significantly decreased CS+ liking. Neither procedure effectively reduced cue-elicited craving. Outcome-specific PIT was observed across conditions, though counterconditioning lead to a general decrease in instrumental responding to all stimuli in the test phase. These findings suggest that counterconditioning more effectively targets the affective value of conditioned stimuli and reduces food cue reactivity compared to extinction, though its impact on PIT warrants further investigation.

Childhood overweight and obesity are significant public health concerns. Eating behavior profiles using person-centered analysis have been utilized to understand patterns of commonly co-occurring eating behaviors within subgroups of individuals. However, eating behavior profiles, particularly in infancy, remain largely unexplored. Therefore, the aims of this study were to investigate person-centered eating behavior profiles in infants and their associations with infant and parental factors and rapid weight gain (RWG). Online survey included validated measures of infant eating behaviors and parental feeding practices. Infant height/length and weight were reported by parents and used to calculate RWG. Latent profile analysis was used to identify eating behavior profiles. Multiple regression analysis was performed to investigate the associations between parental feeding practices, RWG and eating behavior profiles. Chi-square was used to examine associations between demographics, milk type and eating behavior profiles. A total of 1092 parents of infants under 4 months of age (540 boys, 552 girls) completed the survey. Three unique eating behavior profiles were identified: Food Avoidance (24%, n = 263), Balanced Eating (58%, n = 633), and Food Approach (18%, n = 196). Use of food (milk) to calm was positively associated with the Food Approach profile (p < 0.001) and parental-led feeding with the Food Avoidance profile (p < 0.05). RWG was not associated with eating behavior profiles (p > 0.05). This study indicates that eating behavior profiles emerge in infants under four months old. The findings of this study will advance our knowledge of heterogeneity in infant eating and development and the environmental influences by parental feeding practices.
