Whether it's freshly baked bread, a spicy curry or melted chocolate, there's no limit to the amazing smells we get from our food.
But according to a new study, sniffing your dinner before you eat it could actually make you gain weight.
The research, published in Cell Metabolism, claims that the body's sense of smell seems to be tied to its decision to store fat instead of burning it off.
Scientists used three groups of mice - a set whose sense of smell was briefly disabled, a set of 'super smellers' and a control group - and fed them all a high-fat diet.
The mice whose sense of smell had been tampered with barely gained any weight, while the regular mice doubled in size.
Mice who had gained weight then lost it after their sense of smell was removed, without any changes to their diet.
The researchers said that this could have big implications for humans, as their sense of smell could be "turned off", fooling their brain into burning calories.
However they pointed out that this would take a lot of the enjoyment out of food.
"People that don’t have a sense of smell can get depressed. They lose all pleasure of eating."
