Think about the last meal or snack that you had.
Can you describe:
how you ate?
did you eat slowly?
were you distracted?
did you eat with others?
why you ate?
were you hungry?
was it offered to you?
what you ate?
what food and drink did you have?
when you ate?
what time was it?
how long had it been since the last time you ate?
where you ate?
were you in a space meant for eating?
how much you ate?
how much food and drink did you have?
Being able to recall and describe answers to these questions means you were likely being mindful of your eating habits.
