Trial summary

The goal of this randomized control trial is to compare the effect of a liquid formula rich in nutrients and low in calories (supplement) with the progressive diet with conventional foods that we usually recommend in patients after surgery. Read more about this study

About this study

Official title: Efficacy of a Specific Complete Formula on Nutritional Status and Coverage of Protein Requirements After Obesity Surgery Compared to the Traditional Progressive Diet: a Prospective Randomized Study

The goal of this randomized control trial is to compare the effect of a liquid formula rich in nutrients and low in calories (supplement) with the progressive diet with conventional foods that we usually recommend in patients after surgery. The main question it aims to answer is if the addition of a high-protein, volume-controlled nutritional supplement as a fundamental part of the diet during the first two months after surgery will preserve the patient's nutritional status and prevent the appearance of nutritional deficits and associated complications.

Participants will be evaluated at the beginning, at 1 month and at the end of the study (2m) and the following determinations will be made:

  • Analytical determination
  • Nitrogen balance by determining urea N2 in 24-hour urine
  • Anthropometric determinations
  • Body composition determined by impedanciometry
  • Resting energy expenditure and nutrient oxidation measured by indirect calorimetry.
  • Energy, protein and hydration intake.
  • Gastrointestinal tolerance through self-registration of symptoms. Researchers will compare the effect of a complete hypocaloric liquid formula group with the usual progressive diet group to see if they achieve the protein intake goal established for patients after obesity surgery, preservation of nutritional status and lean mass during the rapid phase of weight loss and the gastrointestinal tolerance during the first two months after surgery.

Study groups in NCT06267677
Study groupRoleWhat they receive
High protein liquid formulaExperimentalPatients allocated in the intervention group (n=15) received 4 high-protein shakes and the corresponding standard vitamin-mineral (VM) supplementation according to our post BS protocol, then progressed towards a diet that combines traditional foods with 2 hLF shakes per day and VM supplementation for 15 days. Over the following 15 days, patients continued to normalize their diet, including a single hLF shake per day and continued with VM supplementation.
Receives: Dietary Supplement: High protein liquid formula
Standard care dietNo interventionPatients in the control group (n=35) followed the traditional protocol after bariatric surgery (sCD-group) consisting of a progressive diet with traditional foods, recommendation of 23g/d of protein powder and standard vitamin-mineral supplementation during the first 2 weeks after the surgery. From then on and according to current dietary protocols, the recommendation for protein powder decreases from 23g to 15g up to the end of the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

    Nutritional status and the preservation of lean mass during the rapid phase of weight loss

    Measured: 2 months

  3. Tolerance

    Gastrointestinal tolerance during the first two months after surgery.

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing High protein liquid formula in people with Body Composition and Obesity, run by Hospital Clinic of Barcelona.

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 1 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 20 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

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?

protein intake (time frame: 2 months). The study lists 3 primary outcomes in all. 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 20 Feb 2024.
