Cooking peanuts made it easier for mice to digest the fats inside them, so less fat showed up in their poop and they gained more weight—even though they ate the same amount and moved the same. This means cooking helps unlock more energy from peanuts.

Cooking peanuts breaks open the tiny protective shells around the fat inside, making it easier for your body’s digestive juices to reach and break down the fat.
