If you consume carbohydrates that make your glucose and insulin levels spike (processed carbohydrates will do the trick), the sudden drop in blood sugar that ensues leaves you hungry, and sometimes dizzy and anxious, just one or two hours later. (Severe hypoglycemia can make you faint or even cause a seizure.) How do you address hypoglycemia? Ironically, the easiest, most immediate way is to eat food with high levels of glucose, which is what you usually crave anyway. But if all you’re eating is highly processed carbs with high glucose levels, this cycle of ups and downs never ends.
