A new study suggests fat itself breeds a well-known appetite-stimulating hormone
As if fast food and TV werent enough to make and keep us fat, a new study from the University of Western Ontario has found that our fat may also be making us fat. Neuropeptide Y (NPY) is an appetite-stimulating hormone produced by our brains, which is responsible for a lot of our drive to eat. Scientists had previously thought that overweight people simply had more NPY flowing from their heads than they needed. As it turns out, the UWO study found that not only do our brains produce NPY, but our abdominal fat makes it as well.
