motivation of eating
Biological factor
* Associations between stomach and hunger
* Hunger relies on
- role of brain
- blood sugar
- hormones
* Brain regulation
- hunger comes from hypothalamus
-lesioning of lateral hypothalamus= lack of interest in food
- lesioning of lateral ventromedial mucleus= animals eat the solar system
- paraventicular nucleus---> modulation of hunger
- theory time!-> neural circuits go through brain, controlling hunger
* glucose and digestive regulation
- food converts to glucose
- glucostatic theory- proposal of hunger is regulated by rise and fall in blood glucose levels and monitored by glucostats.
- glucostats-> neurons sensitive to glucose in surrounding fluid
- after you eat, cells in stomach send signals to inhibit eating (walter cannon thought you get hungry b/c your stomach growls... not totes wrong!)
* Hormone regulation
- insulin- hormone that extracts glucose from blood
- leptin- hormone that's produced by fat cells and released into blood stream. provides hypothalamus with information on body's fat stores!
- hi leptin-> lo hunger

ENVIRONMENT FActors (damnright caps lock, you mad bro?)
* food availability and shit
- humans and other animals eat, not for energy, BUT FO THE YUM YUMMY TUMMY OF EATING
- food related cues, like watching t.v, make you want food
* learned preferences and habits
- different areas have different eating preferences (aka eating duck fetuses)
- humans have innate taste preferences
- young kids eat unfamiliar food only if they see adult eat it first
* stress and eating
- stress eating common among chronic dieters

Eating and weight
* Criteria of obesity varies
* BMI-> weight in Kg divided by height in meters squared
* insert obesity conditions here
* factors and obesity
1. genetic predisposition
2. excessive eating and inadequate excercise
3. concept of set point
- people who diet gain weight people who gain weight lose it.
-settling point theory- weight tends to drift around level at which constellation of factors determine food consumption and energy expenditure achieve an equilibrium
4. dietary restraint
- dietary restraints lead to obesity
- restrained eaters-> people who work consciously to control eating overtime (chronic dieters) (feels guilty about eating)

Sexual motivation
I'm not typing this awkward stuff. YOU READ IT
Emotion
I kinda sort of lost the majority of my emotion notes.. sorry?
