Pennington Biomedical invents pet food that can help animals lose weight, live longer - WAFB

Pennington says the food restricts methionine, an amino acid. When the liver senses a low level of methionine, it releases the hormone FGF21, which makes animals burn more calories, reduces their body fat, decreases circulating and liver fats, and increases insulin sensitivity.
