Cravings vs Hunger: The Brain Loop Behind the Demon
Hunger is your body asking for fuel. A craving is a cue firing a dopamine want that is not a fuel need. In Burnie both get logged, but only hunger gets a meal.
You are sitting full after dinner. Then you see an ad for kulfi. Suddenly you want kulfi. Are you hungry? No. That is a craving, and it has a different engine. This is not the simple 'hungry or craving?' body-vs-mind test (that is a different article). This is the brain mechanism behind a craving, the 'demon', and the Burnie-method move for both.
Two different engines in your body
Hunger is homeostatic. That means it is about fuel balance. Your stomach makes a hormone called ghrelin when it is empty. Ghrelin tells your brain, 'send fuel.' Its secretion becomes activated when the stomach is empty and inhibited when it is stretched after a meal. That is real hunger, a fuel signal. A craving is different. It is cue-triggered. The sight, smell, thought, or routine around a food fires a dopamine 'want' in the brain. Dopamine is not a fuel signal. It is a learning-and-wanting signal. In one study, a food-predicting cue released dopamine even in rats that were already sated. The cue, not the empty stomach, drove the want. That cue-to-dopamine loop is the demon. It is a learned loop, and it can fire with no fuel need at all.
Hunger vs craving at a glance
If I crave a food, my body must need that food.
mostly falseMostly false. A craving is usually a cue firing a dopamine want, not a fuel need. The craving-to-dopamine loop can drive you toward calorie-dense food even when your stomach is full and your fuel is fine. The specificity gives it away: wanting only chocolate is a cue-want, not a fuel call. Your body may need fuel sometimes, but a specific craving is not proof of that.

The bottom line
Hunger is a fuel signal from an empty stomach, ghrelin talking to your brain. A craving is a cue firing dopamine, a learned demon that wants one specific food. In Burnie, both get logged the same way, so the deficit math stays honest. The difference is your response: answer hunger with a real meal, ride a craving like a wave, or eat it as a counted choice. No food is banned, nothing is hidden.
