Clinical Trial Summary

Protocol Number: 22DK0002 Title: Effects of Ultra-processed versus Unprocessed Diets on Energy Metabolism Background: Many diets worldwide include both processed and unprocessed foods. Researchers want to study the effects these foods have on a person s health. Objective: To study how different diets affect a person s health and metabolism. Eligibility: Adults aged 18 60 without diabetes who have stable weight and can exercise. Design: Participants will be screened with: Medical history Physical exam Heart tests Resting energy expenditure (to determine calorie needs) Blood and urine tests 20-minute stationary bicycle session Food, diet, and mental health questionnaires Participants will stay at NIH for 4 weeks. They will receive 3 meals a day and may eat as little or as much as they want. The diet will change each week. Their weight will be recorded daily. They will ride a stationary bicycle daily. Each week, they will do the following: Spend 1 day in a special room that assesses their metabolism Have 24-hour urine collections Give skin and fecal samples Repeat some screening tests Have scans to measure body fat Complete computerized behavior tasks Wear an activity monitor to track physical activity Wear a glucose monitor. A sensor will be inserted under the skin with a small needle. It will be replaced weekly. Take taste tests. They will swish water and flavored liquids around in their mouth and pick which ones had a non-neutral taste. They will also compare liquids for which ones taste better. Participation will last for 4 weeks. Sponsoring Institution: National Institute of Diabetes and Digestive and Kidney Diseases ...

Clinical Trial Description

This is a randomized crossover study of adult volunteers to determine the health effects of four different diets varying in non-beverage energy density, hyperpalatable foods, as well as the degree, extent, and purpose of processing according to the NOVA classification system. Objectives/Endpoints: Primary Aim: To determine differences in health effects during four 1-week test diets. Secondary Aims: To determine differences in mean eating rate (grams per minute) and palatability of meals between the four 1-week test diets. Exploratory Aims: Several exploratory measurements are planned to help comprehensively phenotype the effects of the test diets and are intended to be hypothesis-generating. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
