This technical note introduces the Household Hunger Scale (HHS), a simple, new indicator to assess household hunger in food insecure areas. The HHS consists of three questions and three frequencies that, when administered in a population-based household survey, allows for estimating the percent of households affected by three different severities of household hunger: 1) Little to no household h...

Expectations about a food's satiating capacity predict self-selected portion size, food intake and food choice. However, two individuals might have a similar expectation, but one might be extremely confident while the other might be guessing. It is unclear whether confidence about an expectation affects adjustments in energy intake at a subsequent meal. In a randomized cross-over design, 24 sub...

Mesolimbic dopamine encodes the benefits of a course of action. However, the value of an appetitive reward depends strongly on an animal's current state. To investigate the relationship between dopamine, value, and physiological state, we monitored sub-second dopamine release in the nucleus accumbens core while rats made choices between food and sucrose solution following selective satiation on...

It is well known that a competitive equilibrium may fail to exist when preferences are possibly satiated. We show that this non-existence problem does not arise if one of the commodities is paper money. Moreover, and equilibrium is weakly Pareto efficient in the economy with money. This paper therefore gives an economic solution to the classical problem of non-existence of competitive equilibri...

body weight is influenced by both food intake and energy expenditure. acylated ghrelin enhances appetite, and its circulating level is suppressed by growth hormone. data on the acylated ghrelin responses to exercise of different intensities in obese individuals are currently not available. this study examined the effects of an intermittent exercise protocol on acylated ghrelin levels and hunger...

The impact of sleep deprivation (high sleep pressure) vs sleep satiation (low sleep pressure) on waking EEG dynamics, subjective sleepiness and core body temperature (CBT) was investigated in 10 young volunteers in a 40 h controlled constant posture protocol. The differential sleep pressure induced frequency-specific changes in the waking EEG from 1-7 Hz and 21-25 Hz. Frontal low EEG activity (...

We examined the effects of three different presession conditions on tangibly maintained problem behavior for 2 students with autism, using individual-participant multielement designs. First, an analogue functional analysis demonstrated that problem behavior was maintained by access to tangible items. Next, topographies of item rejection were identified. Finally, students were exposed to (a) bri...

The acute effect of complexity in aroma composition on perceived satiation and food intake was investigated in 41 young, healthy, and normal weight subjects. Subjects consumed 2 different strawberry-aromatized sweetened yogurt products (i.e., test and placebo product) in either an olfactometer-aided or an ad libitum eating experimental design. The test product was aromatized with a multicompone...
