About this study
Official title: Analysis of Ghrelin Concentration in the Blood Serum of Patients With Different Nutritional Status Following Consumption of a Standarized Meal.
This study evaluated differences in serum concentrations of ghrelin among individuals with varying nutritional status following a standardized meal.
A total of 80 adults were enrolled and stratified by BMI. Fasting and postprandial ghrelin levels were assessed at multiple time points.
Additionally, dietary habits, physical activity, body composition, and resting energy expenditure were evaluated to explore their association with hormonal responses.

Study Objectives
- The primary objectives was to evaluate differences in serum concentrations of ghrelin among patients with varying nutritional status following consumption of standarized meal (cross-over design).
Secondary Objectives
- To compare fasting serum concentrations of ghrelin across nutritional status groups.
- To assess postprandial changes (60, 120, 1880, and 240 minutes) in ghrelin depending on nutritional status.
- To compare fasting versus postpradial ghrelin levels. Methods
Study Population: A total of 80 adults (aged 40-60 years) were enrolled and stratified by BMI into the following groups:
Normal weight (BMI 18.5-24.9) Overweight (BMI 25.0-29.9) Obesity class I (BMI 30.0-34.9) Obesity class II and III (BMI ≥ 35.0) Exclusion criteria included: carbohydrate metabolism disorders, endocrine disorders, renal and/or hepatic failure, gastrointestinal diseases, history of gastroenterological and bariatric surgery, pharmacological treatment or other preparations whose effect on metabolic and hormonal changes is documented or unknown, pregnancy, lactation and other diseases that may affect the obtained results.
Dietary Intake, Physical Activity, and Quality of Life:
Validated questionnaires (including QEB, IPAQ, WHOQOL-BREF, AND TFEQ-R18) were used. Dietary intake was assessed using 24-hour dietary recalls collected over 3 days (2 weekdays and 1 weekend day).
Nutritional Status Assessment: Anthropometric measurements (body weight, height, waist and hip circumference) were obtained, and BMI, WHR, WHtR, and RFM were calculated. Body composition was assessed using dual-energy X-ray absorptiometry (DEXA).
Biochemical Measurements: Fasting blood samples were collected to assess: glucose, insulin, lipid profile, CRP, ALT, AST, uric acid, creatinine, and ghrelin. After ingestion of a standarized isocaloric meal (Nutridrink Standard), additional blood samples were collected at 60, 120, 180, and 240 minutes.
Resting energy Expenditure: REE was measured using indirect calorimetry (Q-NRG+, COSMED).
Statistical Analysis: Data were analyzed using Statistica 13.3 (StatSoft).

Questions about this trial
What is this clinical trial studying?
A study testing Nutridrink Protein in people with Obesity, run by Medical University of Bialystok at 1 site in Poland.
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 7 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 Jun 2026. 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 Poland. 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?
Postprandial serum ghrelin concentration (time frame: 24 months (analyzes were performed throughout the study period).). 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 NCT07627802, 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?
