I see these as three separate physical and mental categories. If I'm simply hungry, that is the easiest to cope with. I will sometimes let the hunger stay for awhile, but more often I will eat a healthy snack (fruit, vegetables) unless it's close enough to mealtime to wait it out. Hangry is a tough one because it's driven by mood more than hunger. That's the time I tend to want to open the refrigerator and tilt it in my direction. Hankering can be tricky for me because it is very protean and the tips or solutions that often work don't always. To wit, chew gum, have a cuppa tea, go for a walk, exercise, distract myself with something, etc. The problem with saying I'll have a bite of something I crave inevitably leads to way more than I intended to eat. My hankerings occur mainly in the evening.
