Tasty food is highly rewarding, and we saw in Chapter 3 that over time, dopamine release can be transferred to anything that predicts a reward. In the real world, this means the logo of your favourite restaurant, or the smell of freshly baked cookies. Experiencing these cues could drive you to seek the food as a habit, overriding any notion of whether you ‘need’ the food (how hungry you are) or whether you ‘like’ it.
