Overeating is a big issue in the United States, and now all around the world. One of the reasons for this is that we are eating "empty calories" or foods that are nutrient-depleted instead of nutrient-dense. Monoculture, synthetic fertilizers, and mismanaged grazing are just some of the reasons we are losing nutrients from our soil.
A bit about hunger and appetite here. Us, as human beings, get hungry because our body needs nutrients to live and thrive. If we didn’t have this strong drive to eat, we could easily get distracted and forget that we need food. So having a healthy appetite is key to our survival. We’ve all heard that overweight people have poor willpower which is absolutely untrue and, quite frankly, has screwed up a lot of people and their association with food. The appetite is such a powerful force. You’re not going to white-knuckle it and fight through, not eating out of sheer willpower alone. It’s just not going to happen. You may get away with it for a bit, but that’s not exactly a good thing.
