Heather Walden, et al at the Pennington Biomedical Research Center conducted a study on Scientific Intake’s device that was published in the peer reviewed journal Obesity Research in November 2004. The study was conducted on thirty-two adults randomly assigned to the control or test groups. Day one served as a baseline for both groups, day two test group subjects ate with the device. Device subjects reduced food intake by 23%, caloric intake was 533 kCal less than the non-device control group.
It was also revealed that the device group who consumed less food did not differ on hunger levels from the control group. The abstract concludes: “These findings suggest that the use of this tool during meals significantly reduced food intake. The reduction of food intake was not associated with changes in hunger or satiety.”
