Chances are when you are in a snacky mood, you probably don't really need to eat anything. If you are anything like me, you love the chewing sensation. I know that sounds terrible! But it's so true! Sometimes, I just want to chew something... for no reason. If you have done any reading on emotional eating, a lot of times when you have the sensation to chew, it is because you have conditioned yourself to need to chomp on something when you are angry or frustrated. Hence, the chewing sensation where you literally chew away your problems. So you crave something crunchy, like potato chips, or even something gummy, like gummy bears, so you can chew aggressively.
I found this litte chart on Pinterest to help you distinguish what action really needs to be taken when you feel like snacking.
