Time Restricted Feeding on Nonalcoholic Fatty Liver Disease
A study testing Time restricted feeding and Continuous Energy Restriction in people with Nonalcoholic Fatty Liver Disease, run by Nanfang Hospital, Southern Medical University at 1 site in China.
Trial summary
Time restricted feeding (TRF) is a novel type of intermittent calorie restriction diet that involves eating a daily period of 8 hours or less. This is a randomized controlled trial to evaluate the effect of time restricted feeding (TRF) on hepatic fat contents and cardiometabolic risk factors in obese adults over 6… Read more about this study

This is a randomized controlled trial to evaluate the effect of time restricted feeding (TRF) on hepatic fat contents and cardiometabolic risk factors in obese adults over 6 months compared to continuous energy restriction (CER).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Time restricted feedingBehavioural
Participants will receive a diet of 1500-1800kcal/d for men and 1200-1500kcal/d for women during a window of 8 h/d (8 am to 4 pm).
Continuous Energy RestrictionBehavioural
Participants will follow receive a diet of 1500-1800kcal/d for men and 1200-1500kcal/d for women, without restriction on feeding time.

Questions about this trial
What is this clinical trial studying?
A study testing Time restricted feeding and Continuous Energy Restriction in people with Nonalcoholic Fatty Liver Disease, run by Nanfang Hospital, Southern Medical University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in intrahepatic fat content (time frame: Baseline and months 6). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03786523, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Nov 2023.
