Reducing Energy Density by Different Methods to Decrease Energy Intake
A study testing Energy density feeding study in people with Obesity, run by Penn State University at 1 site in United States.
Trial summary
The purpose of this research is to investigate how using different methods to reduce the energy density of entrees affects daily energy intake in adults. It is hypothesized that reducing the energy density of entrees will decrease energy intake. Read more about this study

About this study
The purpose of this research is to investigate how using different methods to reduce the energy density of entrees affects daily energy intake in adults. It is hypothesized that reducing the energy density of entrees will decrease energy intake. It is also hypothesized that reducing the energy density by incorporating fruit and vegetables will decrease energy intake more than reducing the energy density by decreasing fat content or adding plain water.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Energy density feeding studyOther
In a crossover design, adults are served breakfast, lunch, and dinner, 1 day a week for 4 weeks. Meal entrees will vary in energy density (100% and 80%) and the method used to reduce the energy density (added fruit \& vegetables, decreased fat, added plain water).

Questions about this trial
What is this clinical trial studying?
A study testing Energy density feeding study in people with Obesity, run by Penn State University at 1 site 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 2 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 11 Nov 2011. 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 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?
Energy intake (time frame: 1 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 11 Nov 2011; AzTrials last refreshed its copy on 27 Oct 2026.
