The meal patterns of 2 cats in a laboratory habitat with variable foraging costs were examined in a foraging paradigm in which subjects could initiate meals at any time by completing a predetermined number of bar presses (the procurement price) and then could eat any amount. From meal to meal, the procurement price either was fixed or varied among a geometric series of five prices. As the fixed...

BACKGROUND High food responsiveness (FR) and low satiety responsiveness (SR) are 2 appetitive traits that have been associated longitudinally with risk of excessive weight gain; however, to our knowledge, no studies have examined the associations between these traits and eating patterns in daily life in young children. OBJECTIVE We tested the hypothesis that higher FR is independently associa...

Background Poor infant and young child feeding (IYCF) practices in the first 2 years of age are among major causes of childhood malnutrition, in developing countries including Ethiopia. It results in irreversible outcomes of stunting, poor cognitive development, and significantly increases risks of many chronic and infectious diseases. This study was intended to assess factors associated with m...

Peripherally active anorectic agents represent a new approach to the pharmacological management of obesity. Two inhibitors of carbohydrate absorption: an alpha-glucosidase inhibitor, acarbose (Bay g 5421) and a alpha-amylase inhibitor, Ro 12-2272, were compared with two novel inhibitors of lipid metabolism: an inhibitor of human pancreatic lipase (Ro 20-0083) and of hepatic fatty acid synthesis...

BACKGROUND Although a regular meal pattern is recommended for obese people, its effects on energy metabolism have not been examined. OBJECTIVE We investigated whether a regular meal frequency affects energy intake (EI), energy expenditure, or circulating insulin, glucose, and lipid concentrations in healthy obese women. DESIGN Ten women [x +/- SD body mass index (in kg/m(2)): 37.1 +/- 4.8] ...

BACKGROUND Total food intake is a function of meal size and meal frequency, and adjustments to these parameters allow animals to maintain a stable energy balance in changing environmental conditions. The physiological mechanisms that regulate meal size have been studied in blowflies but have not been previously examined in Drosophila. RESULTS Here we show that mutations in the leucokinin neur...
