Trial summary

Dietary consumption of fructose has increased by nearly 50% since 1960. A high fructose diet (HFrD) results in greater visceral adiposity and systemic insulin resistance than a high glucose diet. Read more about this study

About this study

Dietary consumption of fructose has increased by nearly 50% since 1960.

A high fructose diet (HFrD) results in greater visceral adiposity and systemic insulin resistance than a high glucose diet. The effects of fructose on liver fatty acid and ATP stores, systemic oxidative stress and cardiovascular status are not fully known.

Read the detailed description

The protocol will assess the following outcomes:

  1. The ultimate fate of this increased hepatic fatty acid production following a high fructose vs. glucose diet
  2. The effect of a high fructose vs. glucose diet on liver ATP stores
  3. The effect of a high fructose vs. glucose diet on markers of oxidative stress
  4. The effect of a high fructose vs. glucose diet on cardiovascular status

Factors critical to carbohydrate metabolism such as systemic insulin resistance, body composition, energy expenditure, physical activity will also be assessed.

32 centrally overweight healthy males with a low baseline fructose intake will be recruited. They will be randomised double blindly to receive 25% of their dietary energy requirements from either fructose or glucose for 14 days.

The sugars will first be taken in an energy balanced and then an overfeeding setting.

Questions about this trial

What is this clinical trial studying?

A study testing high sugar diet in people with Hepatic Fatty Acid Metabolism and Systemic Insulin Resistance, run by University of Nottingham at 1 site in United Kingdom.

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 4 inclusion and 11 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 4 Jul 2012. 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 United Kingdom. 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?

Liver triglyceride content (time frame: 2 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 NCT01050140, 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 4 Jul 2012.
