"What we found is there may be situations where we are driven to seek out and eat very rewarding foods even if we're full, for no other reason than our brain tells us to do so, " said Dr. Jeffrey Zigman, a professor of internal medicine at the University of Utah and lead author of the new study.
- Dr. Zigman and his colleagues administered a hormone called ghrelin to one group of mice and no hormones to another group of mice. T
- he mice who had ghrelin preferred a room where they had previously received high-fat food over one that just offered regular food.
- The mice that did not have the hormone showed no preference.
- The mice who had the hormone were more likely to continue to forage for pellets of food, whereas the other group of mice gave up foraging more easily.
