Researchers say the hormone leptin affects the brain by influencing our desire to reward ourselves with food, even when we are not hungry.
Previous studies have shown that leptin controls our appetite by telling the brain when we are hungry or full.
The new study says researchers were able to decrease the desire to eat in rats by delivering leptin to certain parts of the brain.
The study is published in the journal "Cell Metabolism."
