- Gender: ALL
- Minimum Age: 12 Years
- Maximum Age: 45 Years
- Healthy Volunteers: f

Study Arms:
- GMP Diet/GMP Medical Foods (Type: EXPERIMENTAL): The experimental intervention is the GMP diet followed at home for 3-wk. In this randomized crossover study, half of subjects (n=15) were randomized to receive the GMP diet as the first arm, and half of the subjects (n=15) were randomized to receive the GMP diet as the second arm.
- AA Diet/AA Medical Foods (Type: ACTIVE_COMPARATOR): The experimental intervention is the AA diet followed at home for 3-wk. In this randomized crossover study, half of subjects (n=15) were randomized to receive the AA diet as the first arm, and half of the subjects (n=15) were randomized to receive the AA diet as the second arm.

Based on this trial design, predict the completion outcome and termination type (if applicable).
