Curtis - one thing that may help, and that really stood out as I redid our family diet due to allergies that prevent us from using most store bought prepared or semi-prepared food, is that the body feels full when proper nutrients are received. We eat less when we eat good food.
I am discovering more cost efficient ways to do that. For example, making mother preferments for bread takes less yeast and improves flavor. Buying flour in bulk helps. I am currently working with a neighbor to build tiered shelving that holds trough-type containers for porch. This will allow us to have a full sized garden in a small area and we hope to feed 3 families with it. We grow herbs and share.
Having a deep freezer helps store stuff found on sale.
Desserts and junk can be healthier and more filling, for real! I just made pudding the other day with four ingredients, one being egg yolks, and the whites were used for meringue cookies (three ingredients) but could have been used for omelettes. So many recipes can interact with others to make for no waste!
Oh, and trace minerals help with your body not trying to get them with more food. I started using whole salt to help with that. It looks a bit funky to those not used to it (dark flecks) but is strong and we use less, so it makes up the price, which isn't much more since we do bulk on that too.
