It's amazing how much hunger affects mood, more so than I ever had realized before I came to this lifestyle. On days when I haven't eaten enough I'll find that I'm usually somewhat depressed to just plain out angry at the world. At the back of my mind, I try and tell myself "Eat more fruit! You'll feel sooo much better, Michelle!" but I hardly ever want to hear that when I'm upset. Sure enough, though, give me a banana smoothie, and 15 minutes later I'm feelin' on top of the world.
