The goal of this clinical trial is to learn about, test, and compare health outcomes of high vs. low-processed feeding. The main question[s] it aims to answer are:
• Does consuming a diet rich in unprocessed food improve various health outcomes? Participants will either be instructed to consume a diet rich in unprocessed food for 6 months, or consume their typical diet for 6 months. At various points in the study there will be metabolic health data collected.
If there is a comparison group: Researchers will compare the low-processed group to the typical diet group to see if there are improvements in metabolic health.
