| Phases of Energy Metabolism |
|
Definition
1)Cephalic-prepatory phase,begins with smell,sight of thought of food, ends at absorption
2)Absorptive phase-period energy absorbed into bloodstream from meal is meeting bodies immediate needs
3)Fasting-energy from previous meal is been used and body withdraws from reserves |
|
|
Term
|
Definition
-During cephalic and absorptive phases
1)Cephalic-preps for impending influx
2)Absorptive-minimize increasing fuel levels, by utilizing and storing them |
|

Definition
| Fasting phase:high glucagon, low insulin |

| set point systems are negative feedback systems, they act to maintain homeostasis |
|
|
Term
|
Definition
-Body aims to operate at a set point of blood glucose
-set point for body fat
--thought to be complementary of each other |
|
|
Term
| Problems with Set-point theories |
|
Definition
1)ancestors needed to eat far past their set point to be able to survive harsh times
2)a high calorie drink before a meal doesnt satiate hunger
3)dont take into account taste,learning, and social influence |

| Positive-incentive Perspective |
|
Definition
humans aren't driven to eat by energy deficits, but rather the pleasure of eating
-we have evolved to crave for it |
|
|
Term
|
Definition
| small amounts of food actually increase hunger. Small amounts of food consumption are effective in cephalic responses |

Term
|
Definition
after already eating one food, the positive-incentive value plummets
-encourages a varied diet |

Definition
excessive eating caused by lesions to the ventromedial hypothalamas
1)dynamic- soon as the operation happens, gross excessive overeating until reaching obesity
2)static-consumption declines to a point where level of obesity is maintained |
