Researchers found that cutting two amino acids common in animal protein—methionine and cysteine—made mice burn significantly more energy. The boost in heat production was nearly as powerful as constant exposure to cold temperatures. The mice didn’t eat less or exercise more; they simply generated more heat in their beige fat. The discovery hints that diet alone might activate the body’s calorie-burning machinery.
