The Six Types of Hunger | Hunger Season: "Resistance to blood sugar cravings is very difficult. It is not just a natural hunger, but it comes with the body in a biochemical panic as low blood sugar means the brain may not get enough fuel and this is the highest priority for the body.
Most people associate blood sugar with diabetes and hyperglycemia. However, a large percentage of the population suffer with the other end of the problem with their blood sugar dropping too low (hypoglycemia) or find their levels are just too unstable and hence they are often fighting this hunger feeling.
Anyone suffering low blood sugar hunger should not be harsh on themselves for eating rubbish but should focus on how it got to the state of being low in the first place."
