The majority of existing research and conventional wisdom would advise against shopping on an empty stomach as hunger is assumed to encourage impulsive choices that typically lead to self-control failure (i.e., favouring short-term gratifications at the expense of long-term goals). Nonetheless, through two studies the current research aims to demonstrate that hungry consumers would not always be disadvantaged when encountering a self-control conflict involving a trade-off choice between a healthy vs. a more palatable but unhealthy choice...

The potential to grow attached microalgae Chlorella vulgaris in fluidized bed bioreactor was materialized in this study, targeting to ease the harvesting process prior to biodiesel production. The proposed thermodynamic mechanism and physical property assessment of various support materials verified polyurethane to be suitable material favouring the spontaneous adhesion by microalgae cells. The 1-L bioreactor packed with only 2.4% (v/v) of 1.00-mL polyurethane foam cubes could achieve the highest attached growth microalgae biomass and lipid weights of 812±122 and 376±37mg, respectively, in comparison with other cube sizes...

The stress response of omnivorous gibel carp (Carassius auratus gibelio) and carnivorous largemouth bass (Micropterus salmoides) with different nutritional history were evaluated. A 2×2 layout, including two fish species (gibel carp or largemouth bass) and two nutritional history (fasted or fed to satiation for four weeks), was used. After feeding or fasting, the fishes were subjected to an acute handling. Fasting resulted in decrease of plasma glucose level and liver glycogen content of gibel carp and largemouth bass...

Lipid content of diet is very susceptible to oxidation, especially when stored for a long time, so for evaluating protective effects of green tea in fish received oxidized oil, this study was done. Lipid content of diet was replaced by oxidized fish oil (OFO) in 0, 50, and 100%. Green tea extract (GTE) was added to diet in three levels, 0, 5, and 100 mg/kg giving a total of nine experimental diets. Two hundred and seventy sturgeon hybrid of Sterlet (Huso huso ♀ × Acipenser ruthenus ♂) with initial weight of 212...

The gut plays a central role in energy homeostasis. Food intake regulation strongly relies on the gut-brain axis, and numerous studies have pointed out the significant role played by gut hormones released from enteroendocrine cells. It is well known that digestive products of dietary protein possess a high satiating effect compared to carbohydrates and fat. Nevertheless, the processes occurring in the gut during protein digestion involved in the short-term regulation of food intake are still not totally unraveled...

REVIEW
Christopher L Melby, Hunter L Paris, Rebecca M Foright, James Peth
Metabolic adaptations occur with weight loss that result in increased hunger with discordant simultaneous reductions in energy requirements-producing the so-called energy gap in which more energy is desired than is required. The increased hunger is associated with elevation of the orexigenic hormone ghrelin and decrements in anorexigenic hormones. The lower total daily energy expenditure with diet-induced weight loss results from (1) a disproportionately greater decrease in circulating leptin and resting metabolic rate (RMR) than would be predicted based on the decline in body mass, (2) decreased thermic effect of food (TEF), and (3) increased energy efficiency at work intensities characteristic of activities of daily living...

BACKGROUND AND AIMS: The gastric mucosa is an endocrine organ that regulates satiation pathways by expression of orexigenic and anorexigenic hormones. Vertical sleeve gastrectomy (VSG), excludes gastric mucosa and reduces gastric volume. Our study aims to investigate the independent effects of altering gastric mucosa on obesity and its related comorbidities. METHODS: Gastric mucosal devitalization (GMD) of 70% of the stomach was achieved by argon plasma coagulation in a high-fat diet (HFD) rat model and compared with VSG and sham (SH)...

BACKGROUND: Little is known about mother-child feeding interactions and how this is associated with food intake and linear growth. OBJECTIVE: To characterize mother-child feeding styles and investigate their associations with accepted mouthful and linear growth in west Gojam, rural Ethiopia. SUBJECTS/DESIGN: Two, in-home, meal observations of children aged 12-23 months (n = 100) were video-taped. The number of mouthful accepted was counted and the caregiver/child feeding styles were coded into positive/negative categories of self-feeding, responsive-feeding, active-feeding, social-behavior and distraction...

The extent to which a food is expected to deliver satiation is called expected satiation. Many factors affect this expectation, including a number of sensory properties such as texture. The present study explores the relationships between two kinds of texture variations in a yogurt and its expected satiating capacity (ESC). One texture variation consisted in adding three types of pineapple particles: fresh pineapple purée (+PP samples), small cubes of fresh pineapple (+PF samples), and small cubes of lyophilized pineapple (+LP samples)...

EDITORIAL
John E Morley
The anorexia of aging was first recognized as a physiological syndrome 30 years ago. Its major causes are an alteration in fundal compliance with an increase in antral stretch and enhanced cholecystokinin activity leading to increased satiation.This anorexia leads to weight loss in aging persons and is one of the component causes of the aging related sarcopenia. This physiological anorexia also increases the risk of more severe anorexia when an older person has an increase in inflammatory cytokines such as occurs when they have an illness...

Although studies in rodents and humans have evidenced a weaker effect of fat in comparison to carbohydrates on the suppression of food intake, very few studies have been carried out in this field in dogs. This study investigates the effects of a high-carbohydrate (HC) and a high-fat (HF) diets on subsequent food intake and blood satiety-related hormones in dogs. Diets differed mainly in their starch (442 vs. 271 g/kg dry matter) and fat (99.3 vs. 214 g/kg dry matter) contents. Twelve Beagle dogs received the experimental diets at maintenance energy requirements in two experimental periods, following a cross-over arrangement...

BACKGROUND: Fibers' properties impact different mechanisms involved in satiety and energy intake regulation and metabolic outcomes. OBJECTIVE: Evaluate the effect of fiber types and menopausal status on satiety and metabolic responses in overweight women. METHODS: In a randomized within-subjects design, 19 overweight/obese women [9 premenopausal and 10 postmenopausal] consumed 3 preloads that varied by fiber content and source: 1) 3:1 ratio of soluble:insoluble fiber (SF), 2) 1:3 ratio of soluble:insoluble fiber (IF), 3) no fiber control (NFC)...

Background: Large portions and high dietary energy density promote overconsumption at meal times. This could be reduced by eating slowly.Objective: Two studies investigated whether texture-based reductions in eating rate and oral processing moderate consumption at breakfast in combination with variations in energy density and portion size.Methods: Adults attended 4 breakfast sessions (2 × 2 repeated-measures design) to consume rice porridge, combining a 45% reduction in eating rate [thin porridge (140 g/min) compared with thick porridge (77 g/min)] with a 77% increase in energy density (0...

The present multimodal MRI study advances our understanding of the corticostriatal circuits underlying goal-directed versus cue-driven, habitual food seeking. To this end, we employed a computerized Pavlovian-instrumental transfer (PIT) paradigm. During the test phase, participants were free to perform learnt instrumental responses (left and right key presses) for popcorn and Smarties outcomes. Importantly, prior to this test half of the participants had been sated on popcorn and the other half on Smarties - resulting in a reduced desirability of those outcomes...

Perinatal malnutrition is associated with low birth weight and an increased risk of developing metabolic syndrome in adulthood. Modification of food intake (FI) regulation was observed in adult rats born with intrauterine growth retardation induced by maternal dietary protein restriction during gestation and maintained restricted until weaning. Gastrointestinal peptides and particularly cholecystokinin (CCK) play a major role in short-term regulation of FI by relaying digestive signals to the hindbrain via the vagal afferent nerve (VAN)...

Individuals with Fragile X Syndrome (FXS) may be affected by several comorbid conditions, both behavioral and medical. Growth findings suggest that they are at an increased risk for obesity and overeating. The Prader-Willi phenotype (PWP) of FXS occurs in less than 10% of patients but it is associated with severe hyperphagia, lack of satiation and morbid obesity. Metformin is a drug used in individuals with high risk for diabetes type 2, obesity or impaired glucose tolerance. It has had a strong safety profile in children and adults with type 2 diabetes and obesity...

OBJECTIVE: In the current study, we use functional magnetic resonance imaging (fMRI) and multi-voxel pattern analysis (MVPA) to investigate whether tobacco addiction biases basic visual processing in favour of smoking-related images. We hypothesize that the neural representation of smoking-related stimuli in the lateral occipital complex (LOC) is elevated after a period of nicotine deprivation compared to a satiated state, but that this is not the case for object categories unrelated to smoking...

DNA remodelling during endoreplication appears to be a strong developmental characteristic in orchids. In this study, we analysed DNA content and nuclei in 41 species of orchids to further map the genome evolution in this plant family. We demonstrate that the DNA remodelling observed in 36 out of 41 orchids studied corresponds to strict partial endoreplication. Such process is developmentally regulated in each wild species studied. Cytometry data analyses allowed us to propose a model where nuclear states 2C, 4E, 8E, etc...

INTRODUCTION: Impaired monitoring of errors and conflict (performance monitoring; PM) is well documented in substance dependence (SD) including nicotine dependence and may contribute to continued drug use. Contemporary models of PM and complementary behavioural evidence suggest that PM works by integrating recent reinforcement history rather than evaluating individual behaviours. Despite this, studies of PM in SD have typically used indices derived from reaction to task error or conflict on individual trials...

INTRODUCTION: In patients with gastroesophageal reflux disease (GORD), co-existence of functional dyspepsia (FD) is known to be associated with poor response to proton pump inhibitors (PPIs), but the contribution of specific dyspepsia symptoms has not yet been systematically investigated. OBJECTIVE: We aimed to characterize the impact of dyspepsia symptoms on response to PPIs in patients with GORD. METHODS: The enrolled subjects were consecutive patients with a diagnosis of GORD...
