A food crisis occurs when rates of hunger and malnutrition rise sharply at local, national, or global levels. This definition distinguishes a food crisis from chronic hunger, although food crises are far more likely among populations already suffering from prolonged hunger and malnutrition. A food crisis is usually set off by a shock to either supply or demand for food and often involves a sudd...

The impact of sleep restriction on the endogenous circadian rhythms of hunger and satiety were examined in 28 healthy young men. Participants were scheduled to 2 × 24-h days of baseline followed by 8 × 28-h days of forced desynchrony during which sleep was either moderately restricted (equivalent to 6 h in bed/24 h; n = 14) or severely restricted (equivalent to 4 h in bed/24 h; n = 14). Self-re...

Hunger is a powerful drive that stimulates food intake. Yet, the mechanism that determines how the energy deficits that result in hunger are represented in the brain and promote feeding is not well understood. We previously described SLC5A11-a sodium/solute co-transporter-like-(or cupcake) in Drosophila melanogaster, which is required for the fly to select a nutritive sugar over a sweeter nonnu...

Responsive feeding has been identified as important in preventing overconsumption by infants. However, this is predicated on an assumption that parents recognise and respond to infant feeding cues. Despite this, relatively little is understood about how infants engage parental feeding responses. Therefore, the aim of this systematic review was to identify what is known about infant communicatio...

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...

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 famotidine as histamine h2 -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 inject...

S o far in this first decade of the 21st century, more than 1 billion people are subsisting on less than a dollar a day, 1 and more than 800 million people are suffering from hunger. Many countries, most notably in Asia, have had spectacular success in reducing their overall rates of poverty and hunger, but these countries still have regions where poverty remains widespread. And despite its hig...

This study investigated the effects of a long bout of aerobic exercise on hunger and energy intake and circulating levels of leptin and acylated ghrelin. Ten healthy male subjects undertook two, 4 h trials in a randomized crossover design. In the exercise trial subjects ran for 105 min at 50% of maximal oxygen uptake and the last 15 min at 70% of maximal oxygen uptake followed by a 120 min rest...

Assessments of hunger and/or appetite are common methods of screening for development of illness-related anorexia. There are limited data to determine whether these methods predict actual food intake in persons with HIV disease. Therefore, the authors examined the relationship between self-reported food intake and subjective ratings of hunger and appetite in 31 adults with HIV infection. Partic...

Supported in part by Grant MH 03030, National Institute of Mental Health. Marihuana smoking or hashish ingestion has long been reported to increase hunger and appetite. "Marihuana hunger" was described as coming on for 3 to 6 hours following the drug, with a special craving for sweets.' Another modern investigation' found that subjects did not experience hunger during the first 3 hours despite ...
