People who are overweight have a greater sense of smell for food, according to new research in the journal Chemical Senses.

Experts already know that part of the brain that processes information about odor is also connected to feeding centers of the brain.

This study found people who were overweight have a far heightened sense of smell for food compared to slim people. This was true especially after that person had eaten not while they were hungry.

Scientists don't know why this is, but say this keener sense of smell might compel the individual to carry on eating, even when they are full.
