They have a high glycemic index GI , which is a measure of how quickly foods raise blood sugar. When you eat a food that spikes blood sugar fast, it tends to lead to a crash in blood sugar a few hours later.
When that happens, you get cravings for another high-carb snack. One study served people milkshakes identical in every respect except that one had high-GI and the other low-GI carbs.
