Chastising yourself for gobbling pizza or chocolate?
It may not be your fault, according to Japanese researchers who have isolated the neurons that drive a craving for carbs - and decrease your appetite for fats.
The team at Japan's National Institute for Physiological Sciences found that will power alone is often not enough to offset the neurons that act under social stress, increasing your appetite, according to the Daily Mail.
They found that lab mice who had the neurons activated ate high-carbohydrate food at a rate of three times the mice under normal conditions - while halving their intake of high-fat food.
The research is the first to demonstrate the way that the brain plays a role in the preference for carbohydrates or fats, said Yasuhiko Minokoshi, a scientist at the institute, who led the study.
