You know how sometimes after you exercise you're absolutely ravenous, but other times

you're kind of not hungry at all? Scientists may have just figured out why, and it's thanks to a

newly identified molecule they're calling an anti-hunger molecule.

In a study published in the journal Nature last week, scientists looked at how small molecules change in the bloodstream during exercise in mice

as part of a broader investigation into the molecular changes that occur in our bodies

when we work out. Quoting from the New York Times, for decades, scientists have known various

substances like the hormones leptin and grelin travel to the brain and prompt us to be more or less

interested in eating. Studies show exercise alters the level of these substances,

but so do diet and sleeping habits. Some researchers began to wonder whether there might be some

kind of exercise-specific reaction that influences appetite. End quote. So this team from Stanford,

Baylor, and other institutions put some mice on a treadmill

and used a mass spectrometer to look for spikes or peaks in certain molecules,
