Who hasn’t been there? The big meal is over, you’re full, but the craving for sweets remains. Researchers from the Max Planck Institute for Metabolism Research have now discovered that what we call the “dessert stomach” is rooted in the brain. The same nerve cells that make us feel full after a meal are also responsible for our craving for sweets afterwards.

To find the cause of the “dessert stomach,” the researchers investigated the reaction of mice to sugar and found that completely satiated mice still ate desserts. The paper is published in the journal Science.

Investigations of the brain showed that a group of nerve cells, the so-called POMC neurons, are responsible for this. These neurons became active as soon as the mice were given access to sugar, which facilitated their appetite.
