Why Eating Carbs May Lead To Stronger Food Cravings

Refined carbohydrates such as corn syrup could trigger food cravings not unlike the cravings that drug addicts experience, new research suggests.
The findings, which are published today (June 26) in the American Journal of Clinical Nutrition, suggest that the quick spike and subsequent crash in blood sugar that comes after eating highly processed carbs activates reward and addiction centers in the brain.

The study was small and looked only at overweight and obese men, but if the findings can be replicated in a larger population, they would imply that avoiding refined carbohydrates is a good weight-loss strategy because people would avoid not only the calories, but the strong cravings they induce.

"Refined carbohydrates seem to be able to provoke food cravings many hours after consumption, at least in susceptible people," said study co-author David Ludwig, the director of the New Balance Foundation Obesity Prevention Center in Boston. "Limiting these foods could help overweight people avoid overeating."
