Energy density of food, gastric emptying, and obesity.
An investigation of gastric emptying suggested that people choosing an energy-dense mixture of dood and drink have an empty stomach sooner--and might, therefore, eat more--than people who take their energy in more dilute form. Support for the notion that energy density (kcal divided by volume of food and drink) might be related to relative body-weight comes from a study in healthy males. A proportion, albeit a small one, of the variance in relative body-weight (Quetelet) could be ascribed to energy density, and the relationship was stronger among the more obese men.
