About this study

This study is designed to determine if the amount of fat and saturated fat in the diet contributes to the development of a condition called fatty liver disease in the absence of changes in weight.

Read the detailed description

A condition called non-alcoholic steatohepatitis is characterized by fat accumulation in the liver and associated inflammation. This condition is strongly associated with obesity, insulin resistance and type 2 diabetes. Diets high in saturated fat result in fatty liver, insulin resistance and liver injury in animal models. Dietary composition may contribute not only to hepatic fat accumulation and insulin resistance but may also promote inflammation leading to chronic liver disease in humans. This study will test the hypothesis that a diet high in fat and saturated fat contributes to liver fat accumulation, insulin resistance and inflammation by comparing the effects of a four-week, weight stable high fat/high saturated fat diet (55% calories from fat/25% saturated fat) with a four-week, weight stable low fat/low saturated fat diet (20% fat/8% saturated fat) in overweight and obese subjects.

Questions about this trial

What is this clinical trial studying?

A study testing high fat/high saturated fat diet and low fat/low saturated fat diet in people with Fatty Liver, run by University of Washington at 2 sites in United States.

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 1 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 3 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

hepatic triglyceride content by MRS (time frame: 4 weeks). 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 NCT00930371, which also lists 2 linked publications.

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 3 Dec 2015.
