Background: Higher-protein meals (>25 g protein/meal) have been associated with enhanced satiety but the role of amino acids is unclear. Leucine has been proposed to stimulate satiety in rodents but has not been assessed in humans. Objective: We assessed the acute effects of lower-protein nutrition bars, enhanced with a leucine peptide (LP), on postprandial appetite sensations in combination with plasma leucine and peptide YY (PYY) in healthy women. Methods: Utilizing a double-blind randomized crossover design, 40 healthy women [28 ± 7...

NEW FINDINGS: What is the central question of this study? Physical exercise has emerged as a non-pharmacological treatment for obesity by promoting changes in energy balance. Despite the accumulated knowledge about exercise effects on energy expenditure, the central question of this study is to understand how an acute session of exercise might affect food intake of male Wistar rats. What is the main finding? The main finding of this work is that food intake in male Wistar rats is decreased in the first hour after physical exercise independent of the intensity...

The reward surfeit model of overeating suggests that heightened brain response to rewards contributes to overeating and subsequent weight gain. However, previous studies have not tested whether brain response to reward is associated with food intake, particularly during childhood, a period of dynamic development in reward and inhibitory control neurocircuitry. We conducted functional magnetic resonance imaging (fMRI) with 7-11-year-old children (n = 59; healthy weight, n = 31; overweight, n = 28; 54% female) while they played a modified card-guessing paradigm to examine blood-oxygen-level-dependent (BOLD) response to anticipating and winning rewards (food, money, neutral)...

Despite ancient knowledge on cocaine appetite-suppressant action, the molecular basis of such fact remains unknown. Addiction/eating disorders (e.g., binge eating, anorexia, bulimia) share a central control involving reward circuits. However, we here show that the sigma-1 receptor (σ1 R) mediates cocaine anorectic effects by interacting in neurons with growth/hormone/secretagogue (ghrelin) receptors. Cocaine increases colocalization of σ1 R and GHS-R1a at the cell surface. Moreover, in transfected HEK-293T and neuroblastoma SH-SY5Y cells, and in primary neuronal cultures, pretreatment with cocaine or a σ1 R agonist inhibited ghrelin-mediated signaling, in a similar manner as the GHS-R1a antagonist YIL-781...

The recent discovery of the medullary circuit driving "hunger responses" - reduced thermogenesis and promoted feeding - has greatly expanded our knowledge on the central neural networks for energy homeostasis. However, how hypothalamic hunger and satiety signals generated under fasted and fed conditions, respectively, control the medullary autonomic and somatic motor mechanisms remains unknown. Here, in reviewing this field, we propose two hypothalamomedullary neural pathways for hunger and satiety signaling...

TRIAL DESIGN: Plant-derived polyphenols have shown potential to alleviate obesity-related pathologies by a multi-targeted mechanism in animal models and human intervention studies. A dietary supplement based on a combination of Lippia citriodora (LC) and Hibiscus sabdariffa (HS) polyphenolic extracts was assayed in a double blind and placebo-controlled intervention study with 54 overweight subjects. METHODS: Blood pressure, body weight, height, triceps, biceps and abdominal skinfold thickness, and arm and abdominal circumferences were taken at the baseline, 30 and 60 days of the intervention period...

BACKGROUND: Research into energy balance and growth has infrequently considered genetic sex, yet there is sexual dimorphism for growth across the animal kingdom. We test the hypothesis that in the chicken, there is a sex difference in arcuate nucleus neuropeptide gene expression, since previous research indicates hypothalamic AGRP expression is correlated with growth potential and that males grow faster than females. Because growth has been heavily selected in some chicken lines, food restriction is necessary to improve reproductive performance and welfare, but this increases hunger...

Obesity is a crucial public health problem worldwide and is considered as the main cause of many chronic diseases. The present study evaluated the effects of Oleoylethanolamide (OEA) supplementation on proximal proliferator-activated receptor-α (PPAR-α) gene expression, appetite sensations, and anthropometric measurements in obese people. This randomized, double-blind, placebo-controlled clinical trial was carried out on 60 healthy obese people in Tabriz, Iran, in 2016. The eligible subjects were divided into an intervention group (who received two 125 mg OEA capsules daily) and a placebo group (who received the same amount of starches) and treated for 60 days...

BACKGROUND: High added sugar (AS) intake is associated with obesity and poor diet quality. Guidelines recommended limiting AS to 5-10% of total energy intake, but palatability and feasibility of this AS intake level is uncertain. OBJECTIVE: To compare adolescents' perceptions of hunger, fullness, and palatability in response to a low AS adequate fiber (LASAF; 5% total energy from AS and 13.5 g fiber/1000 kcal) and a high AS low fiber (HASLF; 25% total energy form AS and 8...

Recently models have attempted to integrate the functional relationships of fat mass (FM) and fat-free mass (FFM) with the control of human energy intake (EI). Cross-sectional evidence suggests that at or close to EB, FFM is positively related to hunger and EI, whereas FM either shows a weak negative or no association with ad libitum EI. Further analysis suggests that the effects of FFM and FM on EI may be mediated by resting metabolic rate (RMR). These studies suggest that energy turnover is associated with EI and the largest determinant of energy requirements in most humans is FFM...

Suboptimal outcomes from behavioral weight loss (BWL) treatments are partially attributable to accumulated instances of non-adherence to dietary prescriptions (i.e., dietary lapses). Results identifying negative internal triggers for dietary lapses are inconsistent, potentially due to individual differences that impact how individuals respond to cues. Impulsivity is one factor that likely influences reactivity to internal states. We examined three dimensions of impulsivity (delay discounting, inhibitory control, and negative urgency) as moderators of the relation between affective and physical states and subsequent dietary lapses at the beginning of BWL...

PURPOSE: Weight stigma is implicated in disordered eating, but much of this research focuses on forms of stigma such as weight-based teasing. METHODS: In a large cohort of adolescent girls (N = 2,036), we tested the hypothesis that being labeled as "too fat" by others predicts subsequent greater disordered eating cognitions and behaviors. RESULTS: Compared with girls who did not report weight labeling, girls who were labeled at age 14 showed an increase in unhealthy weight control behaviors and disordered eating cognitions over the subsequent 5 years...

Pleiotropic effects of spices on health, particularly on glucose metabolism and energy regulation, deserve further clinical investigation into their efficacy. The aim of the current study was to evaluate whether consumption of a black pepper-based beverage (BPB) preload containing 20 mg gallic acid equivalent (GAE) would exert any effect on postprandial glycaemia, appetite sensations, gut hormones, thyroid function, and gastrointestinal well-being after a white wheat bread (WWB) challenge meal containing 50 g available carbohydrates (CHO) compared to a control beverage...
