Hunger and eating

1. Hunger and eating

2. EQ: Why do we eat? Bell ringer: Do you like to eat? What do you like to eat? Why do you eat? What forces you to eat?

3. Internal controls 1. Bloodstream Pathway for eating signals that flow to the brain Fatty acids and blood sugar glucose are food nutrients in the blood When brain receives signals that food nutrients in the blood are low, you feel hungry

4. 2. Stomach When your stomach becomes full it sends signals to the brain Also signals release of insulin, a blood hormone that decreases appetite High insulin causes body cells to take in too much glucose and excess is converted to fat

5. 3. Brain Hypothalamus: regulates eating Neurons in hypothalamus fire when blood nutrients are too high or too low Neurons act like sensors that provide information to the frontal lobes (which decides eating behavior)

6. External Controls 1. Environmental cues Sight or smell of food Time of day Other people eating Clattering of dishes

7. 2. Incentive value of food Incentive declines the more one eats of the same thing Eat more when there is a variety of food(think about thanksgiving)

8. 3. Culture What people eat around you What foods are available

9. 4. Thoughts about food Restrained Eater: Always worrying and trying to control what and how much you eat Unrestrained eater: Unconcerned about controlling your eating
