London: Want to lose weight? Stay clear of meals rich in saturated fat such as lard and butter asconsuming such food affects a part of the brain which helps control hunger, a new study has found.

The fat causes inflammation that impedes the brain to control the food intake. In other words, people struggle to control how much they eat, when to stop and what type of food to eat - symptoms seen in obesity, researchers from University of Naples Federico II in Italy said.
