One time in Hawaii I was looking at a "Sugar in the Raw" type sugar packet. The sugar was grown in Hawaii, shipped to California for packaging, and shipped back to Hawaii, and distributed in trucks to the restaurant.
I will tell you what I did in that situation. I ate the cheap, processed, calorie dense foods, until such time as I could move to a major metropolitan area with better economic opportunities.
Moving to that area (Northern Virginia) was my focus. I did it through sheer willpower and determination.
I had to essentially abandon family and friends to do it however. But I gave myself a better life outcome.
