In the study, volunteers ate about a cup of ice cream at different speeds. Researchers took blood samples before and after eating the ice cream. They found the people who took 30 minutes to finish the ice cream had higher concentrations of gut hormones and reported feeling more full than people who ate the ice cream in five minutes.
The study will be published in the January issue of the Journal of Clinical Endocrinology and Metabolism.
