Food intake in Antarctica.
I . Body-weight, skinfold thickness and food intake were measured at regular intervals in twenty-five young men while on an Antarctic expedition. 2. The mean calorie intake over the year was 3600 kcal/man per day; 12.1 yo of these calories were supplied by protein, 39'8 % by fat, and 48.1 % by carbohydrate. 3. The calorie intake was equivalent to that which would be expected in a moderately act...
متن کاملRegulating food intake.
EVERY ORGANISM INGESTS FOOD (energy). If it takes in too little, it will starve; if it takes in too much, it will become obese. Too little is readily defined as caloric intake less than expenditure, and too much is simply the opposite. Multiple regulatory pathways are known that promote and inhibit feeding and thus regulate energy balance. However, these pathways and their interactions remain i...
متن کاملPeptides and Food Intake
The mechanisms for controlling food intake involve mainly an interplay between gut, brain, and adipose tissue (AT), among the major organs. Parasympathetic, sympathetic, and other systems are required for communication between the brain satiety center, gut, and AT. These neuronal circuits include a variety of peptides and hormones, being ghrelin the only orexigenic molecule known, whereas the p...
متن کاملIncreased food intake and CCK receptor antagonists: beyond abdominal vagal afferents.
THE IDENTIFYING BIOLOGICAL actions of CCK, stimulation of gall bladder contraction (18) and pancreatic enzyme secretion (15), were first detected in extracts of small intestinal mucosa more than 75 years ago. Subsequently, the peptide responsible for these actions was isolated and characterized by Mutt and Jorpes (22). CCK is secreted by small intestinal enteroendocrine cells in response to die...
متن کاملCentral effect of histamine and antihistamines on food intake in freely feeding and food-deprived rabbits
Several lines of evidence suggest that brain histamine may be involved in the central control of food intake. The effect of histamine on feeding is mediated through three kinds of receptors (H1, H2, and H3). The present study was designed to investigate the effect of intracerebroventricular injection of histamine, promethazine (H1 antagonist) and ranitidine (H2 antagonist) on food intake of fre...
