Dr. Kissileff's laboratory also measures changes in physiological variables, such as hormone levels or gastric emptying, and changes in bodily sensations that appear as verbal reports, while humans eat. It has also demonstrated some interesting differences between the way CCK and stomach filling reduce food intake in men and women. The role of various foods and fluids in inducing satiety. It has shown that energy content alone is not the only dimension along which to measure foods for their intake reducing value. Currently, the laboratory is examining the relative contributions of a small number of known factors about foods, such as their energy density, osmolarity, chemospecificity, and rates of gastric emptying, on the development of satiety during a meal.
Some foods containing the same amount of energy are more satisfying than others.
Sensory properties, such as flavor and the ability to change gastric emptying rates, may serve as mechanisms that influence how much one eats during a meal.
