Carbs—most especially processed carbs—drive up insulin. And anything filled with refined carbs doesn’t provide that feeling of fullness that comes with the release of satiety hormones. That’s precisely why it’s so easy to eat six bowls of sugared cereal while you’re watching reruns of Seinfeld, and why it’s almost impossible to eat six servings of buttered broccoli and steak. Broccoli and steak get the message to your brain that you’re full. Processed carbs do the opposite, and often create cravings for more.
