A recently discovered hormone in the brain, NPGL (Neurosecretory protein GL) has been found to increase fat storage in the body even when on a low-calorie diet. It also increases appetite in response to high caloric food intake. Kazuyoshi Ukena of Hiroshima University, Japan, first identified the hormone in chickens, but it is now thought to be a regulator of fat storage in mammals too, including humans. The findings suggest a role in how our ancestors coped with famine and feast but perhaps also points to a possible better understanding of the growing obesity epidemic in North America, Europe, and elsewhere.
