Learn the difference between emotional/behavioral hunger and physical hunger. Emotional/behavior pattern hunger is instant. Physical hunger is gradual. If you notice that you are instantly hungry as soon as you walk in the door from work every day, think about how you can be proactive about this. Having a small, planned snack in the car on the way home is a great way to help with this. That way, when you walk in the door and are instantly hit with the desire to eat, you will be able to clearly tell whether your hunger is physical or emotional/behavioral. Emotional/behavioral hunger can easily become physiological hunger, so try to be more acutely aware of the difference.
