BACKGROUND AND PURPOSE Prevalence of adolescent obesity has increased worldwide. Although diet and exercise patterns are major determinants of weight, recent studies with adults and children have shown that total amount of sleep is inversely associated with body mass index (BMI). The purpose of this study was to examine associations among total sleep time (TST), hunger, satiety, food cravings, ...

The current strength of a person's appetite for food can be observed in any graded expression of the disposition to take a mouthful of food. For this quantitative judgment to measure an influence on hunger/satiety, however, the source of that influence has to be varied independently of other influences at the moment the rating is made.

Many food components can influence satiety or energy intake. Combined together, these food components could represent an interesting dietary strategy in the prevention and treatment of obesity. The aims of this study were: 1) to determine the effect of a functional food in the form of a healthy meal course on subsequent energy intake and satiety; 2) to verify if it is possible to maintain palat...

Nutrition across the lifespan encompasses both preventative and treatment options to maintain health and vitality. This review will focus on the challenge of overconsumption of energy relative to energy expenditure and the consequent development of overweight and obesity, since they are responsible for much of the burden of chronic disease in the developed world. Understanding the mechanisms of...

BACKGROUND Strategies that may increase compliance to reduced energy intakes are needed to reduce the health burden of obesity. Conflicting evidence exists regarding the effects of snacking on satiety and energy intake. METHODS This study compared short-term satiety from two common snack foods, low fat popcorn or potato chips. Using a counterbalanced within-subject design, 35 normal weight no...

Understanding mechanisms in control of feed intake and regulation of energy balance in the ruminant is of great importance if improvement in efficiency of production is to be continued. Although there is evidence in both ruminants and monogastrics that body energy content is regulated, under certain circumstances the system can be overridden with the result being either excessive weight gain or...

Many surgeons and most laypeople think that there is a strict correlation between the size of the stomach and the size of the meals. The term ‘‘stomach reduction’’ became a synonym for weight loss surgeries, as if by reducing the stomach, all meals would automatically be small. However, there is no strict correlation between the size of this organ and the size of meals. Some morbidly obese pati...

The hunger hormone, ghrelin, is produced not only in response to food deprivation, but also released during various types of stress. In recent years, the rise ghrelin levels has come be seen as an essential component stress response. review devoted ghrelin-dependent mechanisms providing reciprocal interaction between hypothalamuspituitaryadrenal cortex axis and dopaminergic reward system. Direc...

The role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of chlorpheniramine as histamine H1-receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male Ross broiler chicks reared in groups of four weeks, 16 samples (control and test) were then in...
