o Carbohydrates, the primary macronutrient in fruits and vegetables, leave the stomach more quickly than fats and protein, decreasing satiety. o Liquids empty from the stomach more quickly than solid food, decreasing satiety. o Rapid drinking allowed him to consume even more calories than he would have had he consumed it more slowly, since it takes a while for the brain to realize that the stomach is full.
