When rats eat soybean oil, their stomachs take longer to empty, and their brains send out hunger-signaling chemicals in a delayed way — so they don’t stop eating right away, even though their bodies are starting to react as if they should.

When rats eat palm oil, their stomachs hold onto the food longer after 3 hours, but they don’t eat more or less over the whole day — so fullness doesn’t seem to control how much they eat.

Eating a lot of soybean oil over a long time might mess up the brain’s control center for hunger, how your body uses energy, and even how you interact with others.
