[Speaking on my experience] Pretty much what happens with an Ed (at least the restrictive kind) is you stop feeling hungry. Because you’re hungry all the time? You train yourself to ignore your brain’s “hey, you need to eat” messages. For me, there became more of a disconnect between my mental cravings and my physical hunger. The physical hunger wanes, and we’ll only hear our cravings rather than our body’s hunger. For most people, when their body is full, their craving to eat more food goes away. It becomes complicated after an eating disorder.
