A study compared the livers of male mice fed either a normal 4% fat diet or high fat 11% diet. The high fat diet resulted in livers that were smaller but more dense than the normal diet livers. Additionally, the high fat diet livers exhibited a grayish-yellow marbling color of fat deposits not seen in the normal diet livers, supporting that the high fat diet induced steatosis or fatty liver. While counterintuitive that the high fat livers were smaller but denser, this may be due to hyperplasia that could lead to liver cancer if studied chronically.
