Here’s Warren Buffett: “Cola has no taste memory. You can drink one at 9am, 11am, 5pm. You can't do that with cream soda, root beer, orange, grape. You get sick of them after a while. The average person drinks 64 ounces of liquid per day, and you can have all 64 ounces of that be Coke.”Same with Doritos, Cheetos, most popular junk food. They are engineered to overcome “sensory-specific satiety” and to give a sense of “vanishing caloric density.”
