This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand how ultra-processed foods affect the way your body harvests and uses energy from food. This study will ask you to follow two different eating patterns — one with lots of processed foods and one with fewer — for two weeks each, with a break in between. Blood tests, breathing measurements, and stool samples will help researchers see how your body responds to each diet.
Many people struggle with obesity, and scientists think ultra-processed foods may play a role in how our bodies use energy. This study aims to understand the connection so doctors can better help people manage their weight.

You'll start with baseline tests: a blood draw, a metabolism test in a small room that measures your oxygen and carbon dioxide, and a body composition scan. Then you'll follow one eating pattern (either 80% or 20% processed foods) for two weeks using meal plans and shopping lists provided by the study. After a break where you eat normally, you'll repeat the tests and follow the other eating pattern for two weeks. The whole study takes about 9 weeks, and you'll collect stool samples at home and track your diet using an app.
