Mindfulness eating reminds me to chew my food. It reminds me that chewing my food somehow enhances its flavour.
And, if I remain aware of my eating, as in awareness on a physical, sensory level, I lessen the likelihood that I will overeat.
We shovel the food from our plate into our mouths, sometimes without ever chewing it. Typically, while we eat, we engage in some other activity, such as reading or watching TV. Before we know it, we've eaten our plate all up, without much awareness of what it felt like, tasted like, smelled like.
Perhaps that makes us want more?
