164b feeding control Flashcards
when should there be more E intake?
growth
pregnant
recovery from illness
components of E expenditure
10% PAL - physical activity level
10% TEF - thermic effect of food (E burned processing food)
80% BMR - basal metabolic rate (majority); depends on lean body mass
Ghrelin
only hunger stimulating hormone (orexigenic) –> hypothalamus
GLP-1
enhances glucose action on beta cells for increased insulin secretion
decreases hunger via vagus nerve
Liraglutide
GLP-1 analog for long term use
increases insulin
decreases glucagon release.
Exenatide
GLP-1 analog for long term use
increases insulin
decreases glucagon release.
leptin effect on lateral area of hypothalamus
lateral area controls hunger (destroy –> anorexia)
inhibited by leptin
leptin effect on lateral area of hypothalamus
lateral area controls hunger (destroy –> anorexia)
inhibited by leptin
leptin effect on ventromedial area
ventromedial area controls satiety (destroy –> hyperphagia
stimulate by leptin
leptin effect on ventromedial area
ventromedial area controls satiety (destroy –> hyperphagia
stimulate by leptin
