Answer

The reasons you might have noted are:

  • to stay alive
  • feeling hungry
  • eating is a ‘habit’ and food was available at that time
  • it is time to eat (i.e. breakfast, lunch or evening meal), there are set times to eat these meals
  • eating is sociable and enjoyable
  • just felt like eating but was not hungry
  • upset or feeling anxious and comfort ate.

There are several reasons for eating (see Figure 3).
