If you’ve ever thought you were addicted to pizza, you might just be right. A recent study from the University of Michigan suggests that some foods really are more addictive than others.

Researchers surveyed people about the foods they can’t put down. The most habit-forming foods typically had two things in common—a high-fat content and a high glycemic load, meaning they spike your blood sugar quickly after ingestion. Foods with a high glycemic load tend to be rich in sugars and refined carbs.

"We found that people who indicated experiencing symptoms of food addiction reported the most problems with foods with a high glycemic load, where the refined carbs hit the system in a rapid, rewarding manner," says lead study author Erica Schulte, a doctoral student. "It may be that people who consume food in an addictive manner find the blood sugar spike more rewarding than those who don't report addictive-like eating."

Previous research suggests that eating sugary foods activates brain regions involved in processing reward.
