The End of Overeating
After the 1980s, people began to gain a lot of weight.
1994: Journal of American Medical Association: all races and sexes have dramatic weight increases.

Pg. 6: “drive for food.” “over-powering push to eat”
Over-eating causes obesity.
Palatability: food that increases the need for food.
Bliss point: greatest pleasure from sugar, fat, and salt…eating until the brain can’t take the taste anymore…
If the mixture (sugar, fat, salt) brings pleasure, it can reinforce the need for more of the food.
EATING ISN’T ABOUT GETTING ENERGY TO THE BODY, OR ABOUT HUNGER.
Taste – stimulation – goes to brain, not stomach. REWARD SYSTEM. This system creates pleasure in the body.
Homeostatis system: digestion
P10: reward system is winning –
food has gotten people addicted
unhealthy ingredients :
palatable ingredients creates pleasure in the reward system of the brain…
reinforcing: drives eaters to eat more
location can be reinforcing…ASSOCIATION…of place with food. Association: relating something??? Combining them…combine food with places…its about memory…it connects one with pleasure…memory connects one with pleasure…the memory works by reminding the body where pleasures…CUE: a thing that motivates our behavior (ex: ad)…
animal research – 33 – “high sugar, high fat foods are reinforcing” the power of cues: cues are STIMULI
ingredients can be stimuli
