From what I've read, the craving for carbs is an adaptive evolutionary response, from an environment where food was scarce. Carbs were only available in the summer/spring, and food became even more scarce in autum/winter. Thus, humans developed a powerful chemical response to carb intake - we crave carbs because they were the only means to fatten up and avoid starvation and death.
