What is being tested?
The study compares bodily responses to two types of meals: one made entirely of whole foods like fresh veggies and another consisting of ultra-processed items such as hamburgers. The goal is to understand how these different meals affect our body's metabolism.See study design
What are the potential side effects?
Since this trial involves consuming regular meals (whole food or ultra-processed), there aren't typical side effects like in drug trials. However, participants may experience digestive discomfort depending on their individual reactions to the meal components.
