To understand how parents of adolescents attempt to regulate their children's eating behaviors, the prevalence of specific food-related parenting practices (restriction, pressure-to-eat) by sociodemographic characteristics (parent gender, race/ethnicity, education level, employment status, and household income) were examined within a population-based sample of parents (n=3709) of adolescents. L...

The role of the pineal gland in mediating reproductive regression in response to nonphotoperiodic cues was assessed. A proportion of deer mice (Peromyscus maniculatus) undergo gonadal regression subsequent to moderate food restriction. The reproductive regression after inanition qualitatively and quantitatively resembles short-day-induced regression. The physiological mechanisms responsible for...

The effects of a 3-d peripheral administration of an alpha-MSH agonist, MTII, on body weight and the expression of uncoupling proteins (UCPs) and carnitine palmitoyltransferase-1 were determined in lean and genetically obese fa/fa rats by comparing MTII-treated animals with two different control groups, one being ad libitum fed, the other pair-fed to the amount of food consumed by MTII-treated ...

Nausea and emesis are common side effects of gastrointestinal disease. Reports indicate that ghrelin and endocannabinoids, agents that stimulate appetite, also reduce emesis evoked by chemotherapy treatment, which suggests that stimulation of feeding inhibits the emetic system. In the following study we conducted a more direct test of this hypothesis by determining the impact of manipulating th...

Evidence linking food restriction and food craving is equivocal. This study investigated whether dieting was associated with a greater frequency of food craving. Dieting to lose weight was distinguished from watching so as not to gain weight. Participants were 129 women (mean age=41 yrs): 52 were currently dieting to lose weight, 40 were watching their weight, and 37 were non-dieters. They comp...

Insulin, like leptin, is considered as a lipostatic signal acting at a central level. Aging and age-associated adiposity have been related to the development of leptin resistance in Wistar rats. In the present article, hypothalamic insulin response during aging has been studied in Wistar rats. Thus, the effects of intracerebroventricular infusion of insulin during a week on food intake and body...

To investigate the control over drinking and feeding behavior by the light-entrainable circadian pacemaker, rats were maintained in a 12 h:12 h skeleton photoperiod for 36 days with both food and water restricted to the subjective day. During the restriction period most of the food and water intake was concentrated during the first 4 h of the subjective day. The subsequent release into ad lib c...
