Cravings

There was an ad in the subway station today for 7/11 hots dogs and sodas that said something about cravings. It occurred to me that since I started having the shakes and began adding healthy foods into my diet, I have had zero cravings.

It got me thinking. What are cravings? Where do they come from? What do they mean?

I eat adult gummy vitamins every day and am now eating lots of greens, so the normal cravings for healthy foods have no reason to come to me. That means that cravings are a sign from your body that you need something that you're not getting. What does it mean, then, when we crave things that are not healthy? It leads me to believe that by eating unhealthy foods, we create an unnatural state within our body wherein it then believes itself to be in need of it when we don't have it. Even though this is not true.

What do you crave? Is it healthy? If not, why do you crave it? Do you want it to stop?
