About this study

The primary aim is to examine and compare the effects of hydrolyzed casein (HC), intact casein (IC) and intact whey protein (IWP) on diet-induced thermogenesis (DIT). Furthermore, to study the effects on appetite regulation assessed by subjective appetite sensations, ad libitum energy intake and appetite regulating hormones.

Whey and casein differ in absorption and digestion rate, with whey being a fast protein and casein being a slow protein. When casein undergoes hydrolysis the absorption and digestion rates approaches the rates of whey. In the present study the importance of absorption rate and amino acid composition, in regards to energy expenditure and appetite regulation, will be examined. HC and IC have identical amino acid composition, but differ in absorption rate, whereas HC and IWP have similar absorption rates, but differ in amino acid composition. We hypothesize that consumption of HC will increase DIT and fat oxidation to a greater extend that IC. Moreover, that HC and IWP will increase satiety shortly after protein consumption, whereas IC will be more satiating after several hours.

The study is a controlled, randomized, 3-arm crossover study. It consists of three visits in a respiratory chamber separated by at least two weeks. 26 healthy, overweight and obese (BMI 27-35 kg/m2) young men will be enrolled and randomized to the order of the three protein supplements (HC, IC or IWP). At each visit protein supplements (containing either HC, IC or IWP) will be served as breakfast, lunch and dinner. Respiratory measures will be obtained over 24 hours and appetite will be assessed by visual analogue scales and appetite regulating hormones. Furthermore, ad libitum energy intake will be assessed.

Questions about this trial

What is this clinical trial studying?

A study testing Hydrolyzed casein, Intact casein and Intact whey protein in people with Increased Energy Expenditure and Increased Satiety, run by University of Copenhagen at 1 site in Denmark.

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 16 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 29 Jul 2013. 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 Denmark. 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?

Diet-induced thermogenesis (time frame: 24 hours). 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 29 Jul 2013.
