Calorie restriction increases life span in many organisms, including the budding yeast Saccharomyces cerevisiae. From a large-scale analysis of 564 single-gene-deletion strains of yeast, we identified 10 gene deletions that increase replicative life span. Six of these correspond to genes encoding components of the nutrient-responsive TOR and Sch9 pathways. Calorie restriction of tor1D or sch9D ...

The amygdala is rich in melanocortin 4 receptors. Because the reduction in dietary fat intake after enterostatin is injected in the central nucleus of the amygdala (CeA) is blocked by a melanocortin 4 receptor antagonist, we investigated the role of melanocortin activity in the CeA in regulating food intake and macronutrient choice. Sprague-Dawley rats, fitted with CeA cannulas, were fed either...

purpose the aim of this study was to determine the effect of ramadan fasting on body composition, calorie intake and physical performance in young female athletes undertaking training sessions during ramadan. methods twelve voluntary female athletes (15-27 years old) were assigned to the research. a prospective study was conducted to investigate the athletes on four different occasions: one wee...

Policies that mandate calorie labeling in fast-food and chain restaurants have had little or no observable impact on calorie consumption to date. In three field experiments, we tested an alternative approach: activating consumers' self-control by having servers ask customers if they wanted to downsize portions of three starchy side dishes at a Chinese fast-food restaurant. We consistently found...

BACKGROUND Calorie posting in chain restaurants has received increasing attention as a policy lever to reduce energy intake. Little research has assessed consumer understanding of overall daily energy requirements or perceived effectiveness of calorie posting. METHODS A phone survey was conducted from May 1 through 17, 2009 with 663 randomly selected, nationally-representative adults aged 18 ...

Two important problems related to food consumption were reported in Malaysia: Malaysia was the sixth rank Asia for highest adult obesity rate; and United Nation that Malaysian consumed an average of 2,910 calories per day. An imbalanced diet high intake calorie-dense need attention reduce obesity. These affect national economies by lowering productivity, increasing disability, raising health ca...

Calorie restriction of young male rats increases plasma prolactin, decreases luteinizing hormone (LH) and testosterone, and disrupts their 24 h secretory pattern. To study whether this could be the consequence of stress, we examined the 24 h variations of plasma adrenocorticotropic hormone (ACTH) corticosterone, growth hormone (GH), leptin, and adrenal corticosterone. Rats were submitted to a c...

Field experiment data were used to study the effect of numeric calorie labels in two fullservice restaurants. Ultimately, both field experiments, despite using different experimental designs, reached the same conclusion: the numeric calorie label had no significant effect on total caloric intake. However, results revealed the addition of a traffic light symbol to the numeric label led to a 67.8...

present study is consistent with there being no difference in glycaemia in the animals, suggesting that abnormalities of carbohydrate metabolism had not developed at this age. It has been shown that calorie supplementation of the diet during suckling can lead to a persistent increase in body lipid content, at least up to 60 days (Wurtman & Miller, 19766). The effect of excess calorie intake on ...
