It's not just what you eat, but when you eat it: Link between fat cell and brain clock molecules shown

It's not just what you eat, but when you eat it: Link between fat cell and brain clock molecules shown: Fat cells store excess energy and signal these levels to the brain. Deletion of the clock gene Arntl, also known as Bmal1, in fat cells, causes mice to become obese, with a shift in the timing of when this nocturnal species normally eats. These findings shed light on the complex causes of obesity in humans.
