Turns out, this so-called "dessert stomach" is real, and new research suggests that we all have a special place in our bodies to accommodate a final sweet treat – except, it's in our brain. A team of researchers has found that a process in the brain that makes us feel full after eating also makes us hungry for sugar.

You lean back from the dinner table, feeling like you physically couldn’t fit another bite in – but then someone offers pie and you just can’t say no. Scientists have now identified the neurons behind the “dessert stomach” phenomenon.

Understanding why we always have room for dessert could lead to new treatments for obesity, researchers have revealed.
