This study, called PREDICT 3, is looking at how different foods affect individuals. Researchers want to improve computer models that predict how your body responds to food, helping to create personalized diet advice. You would participate in a dietary intervention using standardized meals, where your body's response after eating (postprandial response) is measured. This information, along with details about your metabolism, body measurements, sleep, and exercise, will be used to understand how your body reacts to various foods. The study aims to understand how factors like exercise and sleep influence these responses. To join, you must be at least 18 years old, have a BMI of 16.5 or higher, live in the continental US (excluding New York), and be enrolled in the commercial ZOE testing program. The study is currently unclear on its recruitment status.
