The hormone leptin has received considerable attention recently, and a new study suggests women who have higher levels of leptin tend to have fewer symptoms of depression.
Researchers have been looking at the hormone’s role in signaling to the brain that the body has had enough to eat, producing a feeling of satiety.
Leptin, the product of fat cells, signals satiety, or fullness. It is low in thin women and high in obese women, according to the study’s lead author, Elizabeth Lawson, M.D., of Massachusetts General Hospital and Harvard Medical School in Boston.
