The Precision Nutrition New York Study

This study, called The Precision Nutrition New York Study, is looking at how different types of fiber affect your body. Researchers want to understand if eating whole grains or fruits and vegetables, which are both good sources of fiber, changes your body weight and body fat percentage differently. They also want to see how these fiber sources affect the tiny organisms (microbes) in your gut. You might be able to join if you are between 21 and 50 years old and have a Body Mass Index (BMI) between 25 and 30. The study will measure changes in your body weight and body fat percentage over 3-4 weeks to see if the interventions are successful. The current status of this study is unclear, and they plan to enroll 15 participants.

Study design
This interventional study plans to enroll 15 participants. It compares two different dietary fiber interventions: one focusing on whole grains and the other on fruits and vegetables.
What's involved
You would eat either whole grains or fruits and vegetables provided by the study to meet your daily fiber needs for a set period. You would also have your height, weight, waist, hip circumference, and body composition measured, and provide saliva samples.
Compensation
Not stated in the trial record.
Follow-up
Your body weight and body fat percentage will be measured at 3-4 weeks after starting the intervention.

What this trial measures

  • Body weight changes3-4 weeks

    For each intervention (whole grains \& fruits and vegetables), investigators will measure change in body weight in kg = Post-intervention minus Pre-intervention

  • Body fat percentage changes3-4 weeks

    For each intervention (whole grains \& fruits and vegetables), investigators will measure change in fat percentage = Post-intervention minus Pre-intervention
