Document Summary

Some people would say the maintenance of these behaviors. Can eat based on the fact that we will need to eat later. Told us based on puing a balloon in a stomach, didn"t want to eat. Mostly depends on whether the stomach is full or not. Also depends on the level of glucose in the blood. Hypothalamus also tells us if we should stop or start eaing. Empty stomach signals and blood sugar are sent to the hypothalamus. Someimes eat even if we are full, can also be psychological. Sight and smell of food makes us want to eat, high calorie foods are very rewarding. Sugar releases dopamine in a certain area of the brain, same areas where cocaine reward areas are. Variety of food makes a diference, eat more if pumpkin pie and apple pie than just apple pie. One apple is one unit, 1 bag of chips is one unit.
