Abstract:
Objective: There is evidence that reduced sleep duration increases hunger, appetite, and food intake, leading to metabolic diseases, such as type 2 diabetes and obesity. However, the impact of sleep timing, irrespective of its duration and on the regulation of hunger and appetite, is less clear. We aimed to evaluate the impact of sleep loss during the late vs. early part of the night on the regulation of hunger, appetite, and desire for food. Methods: Fifteen normal-weight ([mean ± SEM] body-mass index: 23.3 ± 0.4 kg/m2) healthy men were studied in a randomized, balanced, crossover design, inc

Abstract:
Early meal timing and chronotype are associated with lower BMI, but their impact on appetite is poorly understood. We examined the impact of meal timing and chronotype on appetite and food reward. Forty-four adults were divided into early (EC; Morningness–Eveningness Questionnaire (MEQ) score = 55 ± 5) or late chronotype (LC; MEQ score = 40 ± 6) and assessed for body mass index, habitual energy intake (EI; three-day online dietary record) and eating behavior traits from the Three-Factor Eating Questionnaire (TFEQ).

Abstract:
Macronutrients play an important role in appetite regulation. In addition, adequate nutrient and energy intake, which may be altered by exercise-induced appetite fluctuations, is required to ensure important training outcomes. However, findings regarding appetite responses to macronutrient consumption before training and to different resistance training intensities remain inconclusive. This study investigated the association of three types of macronutrient intake before different intensities of resistance training with appetite.

Puberty is a period of development that alters energy intake patterns.

Ageing is associated with a reduction in muscle mass and strength, termed sarcopenia. Dietary protein is important for the maintenance of muscle mass through the promotion of muscle protein synthesis. However, protein is also reported to be a highly satiating nutrient. This raises concerns that protein intake for musculoskeletal health reasons in older adults may exacerbate age-related decreased appetite and may result in reduced energy and nutrient intake.

There is increasing concern about the rapidly rising incidence of obesity worldwide and its impact both on mortality, morbidity and the cost of healthcare.

Obesity is a causal factor in all these conditions.

Abstract:
The physiological mechanisms controlling the growth, lactation and reproductive cycles of cervids, and the control of allocation of energy to different organs are discussed. The growth cycle may be secondary to an appetite cycle, regulated by changes in the secretion of prolactin, gonadal steroids, and possibly unknown factors. The reproductive cycle is controlled by changes in the release at the hypothalamic hormone GnRH, and by changes in the feedback effect of gonadal steroids. These cycles are probably the result of the timing effects of nutrition and changing photoperiod on an endogenous,

Undernutrition in fetal life programmes risk of obesity and the metabolic syndrome in adult life. Rat studies indicate that exposure to a maternal low-protein diet throughout fetal life establishes a preference for high-fat foods. The present study aimed to assess the effect of low protein exposure during discrete 7-day periods of gestation upon feeding behaviour (full gestation 22 days). Pregnant rats were fed control or low-protein diet, with low-protein feeding targeted at day 0–7 (LPEarly), day 8–14 (LPMid) or day 15–22 (LPLate) of gestation. At 12 weeks of age, offspring were placed on a

Background: Traumatic Brain Injury (TBI) is an impairment with high prevalence amongst the pediatric population. Central Nervous System (CNS) regulates food intake and each region of the brain can be responsible for appetite control network. It seems that TBI might affect appetite control system which could result in overeating or reduced food intake. Hence, the aim of this cross sectional study was to determine, if there is a relationship between daily energy intake and satiety related hormones with Computerized Tomography scan (CT scan) findings in children with mild to moderate TBI.

We compared symptom frequency, severity, timing, and duration in test positive and negative illnesses.

Abstract:
Ghrelin is reportedly a meal-initiation signal based on observations that concentrations increase before meals coincident with rising hunger. However, evidence that ghrelin peaks vary with feeding schedules suggests that it rises in anticipation of an expected meal, rather than eliciting feeding. To explore the entrainment of ghrelin profiles, this study investigated the association between varying habitual meal patterns and plasma ghrelin concentrations. Lean and obese adults following either a short intermeal interval (SII) pattern, with 2.5–3.5 h between their habitual breakfast and lunch t

Abstract:
Food behaviour is a complex and multifaceted cooperation between physiologic, psychological, social, and genetic factors, influencing meal timing, amount of food intake, food preferences, and food selections. Deregulation of the neurobiological mechanisms controlling food behaviour underlies the development of obesity and type 2 diabetes, two epidemics of the present century. Several brain nuclei are involved in the regulation of the different components of food behaviours; the hypothalamus is the key in controlling appetite and energy homeostasis.

Postprandial hyperglycemia (PPHG) is strongly linked with the future development of cardiovascular complications in type 2 diabetes (T2D). Hence, reducing postprandial glycemic excursions is essential in T2D treatment to slow progressive deficiency of β-cell function and prevent cardiovascular complications. Most of the metabolic processes involved in PPHG, i.e., β-cell secretory function, GLP-1 secretion, insulin sensitivity, muscular glucose uptake, and hepatic glucose production, are controlled by the circadian clock and display daily oscillation.

Abstract:
Acute exercise can induce either a compensatory increase in food intake or a reduction in food intake, which results from appetite suppression in the post-exercise state. The timing of food choice—choosing for immediate or later consumption—has been found to influence the healthfulness of foods consumed. To examine both of these effects, we tested in our study whether the timing of food choice interacts with exposure to exercise to impact food choices such that choices would differ when made prior to or following an exercise bout.

Insufficient sleep, a common consequence of modern lifestyle, further disrupts circadian rhythms and always leads to higher body mass index (BMI) and metabolic disturbances. Circadian misalignment affects various aspects of metabolism, including appetite regulation, glucose metabolism, and lipid metabolism.
