Chapter 12 Flashcards
During the fasting phase, the body (excluding the brain) cannot use glucose as a metabolic fuel because
glycogen is needed for glucose to enter the cells of the body
The three phases of energy metabolism are, in sequence,
cephalic, absorptive, and fasting
Small amounts of food eaten prior to a meal - hunger. This is called -
increase; the appetizer effect
Which phase of energy metabolism is triggered by the sight, odor, or taste of food, or just by thinking about eating
cephalic phase
As a consequence of digestion, three different forms of energy are delivered to the body
lipids, amino acids, and glucose
According to the positive-incentive theory, the main cause of hunger in environments like ours is
the presence or anticipation of food
What produces a substantial increase in the caloric intake of laboratory and a significant increase in their body weight
offering them a cafeteria diet, rather than their usual single-chow laboratory diet
Receptors for insulin and leptin and particularly dense in the
arcuate nucleus of the hypothalamus
All set-point systems are - systems
negative feedback
Settling point models of weight regulation cannot explain
that most americans consume more calories than they need
Glucostatic theory is to lipstatic theory as
short-term is to long-term regulation
Evidence suggests that the hyperphagia of rats with large bilateral VMH lesions may result from
increases in insulin release
CCK is to neuropeptide Y as
satiety is to hunger
Human patients who have had their stomachs surgically removed
continue to maintain their body weights by eating more meals of smaller size
Inconsistent with theories that hunger and eating are regulated by set points is the fact that
flavor has a major impact on hunger and eating
