Generally speaking, "conscious eating" means to engage in mindful eating instead of the mindless consumption of food and beverages. Specifically, conscious eating means becoming informed and creating a plan constituted of the best dietary choices to make and then to put that plan into day-to-day behavioral action. In other words, think about what you are about to eat, before you eat it.
Unfortunately, mindless eating is a feature of holiday eating. In contrast to conscious eating, mindless eating more often than not reflects horrible habits of eating such as consuming high caloric, nutritionally void foods and beverages, eating too much, eating too fast and not eating enough, among other unhealthy eating behaviors.
