Eligibility

Age
18 Years to 59 Years

Inclusion criteria

Inclusion criteria: Adult patients up to 59 years of age, of both sexes, will be included; obese with a Body Mass Index (BMI) greater than or equal to 30 kilograms per square meter (kg/m²); followed by the Nutrition Clinic of the University Hospital of Aracaju/Sergipe

Exclusion criteria

Exclusion criteria: Patients who are pregnant; using corticosteroids, antimicrobials and/or prebiotic, probiotic or synbiotic supplements during the study; and who have a diagnosis of inflammatory bowel disease, celiac disease, lactose intolerance, or intestinal resections will be excluded

Design outcomes

Primary

MeasureTime frame
Expected: To assess blood glucose levels using biochemical tests. Fasting blood glucose, glycated hemoglobin, and insulin will be analyzed.;Expected Outcome 1: To evaluate the glycemic level of overweight and obese patients after consuming a supplement containing Lactobacillus casei strains, verified by the biochemical sample collection method using the Immunoturbidimetric Inhibition method for Glycated Hemoglobin (HbA1c), Enzymatic Method for Fasting Glucose, and Electrochemiluminescence for Insulin. A decrease in Insulin, Fasting Glucose, and Glycated Hemoglobin levels is expected. Outcome Finding 1: Evaluate the glycemic and insulin profile, verified by the biochemical sample collection method. It was observed that the mean insulin level decreased from 22.69 ± 24.14 µU/mL to 20.75 ± 26.72 µU/mL. This reduction in insulin was statistically significant (p = 0.028). Fasting glucose (p = 0.66) and glycated hemoglobin (p = 0.79) remained stable and did not show a significant difference.

Secondary

MeasureTime frame
Expected Outcome 1: To evaluate participants' body composition parameters before and after the intervention, verified by the anthropometric data measurement method using a digital scale, wall stadiometer, and inelastic measuring tape. It is expected that a decrease in the parameters of Weight, Body Mass Index (BMI), Abdominal Circumference (AC), Wrist Circumference (WC), Neck Circumference (NC), and Hip Circumference (HC) will be observed. Outcome 1: Evaluate body composition parameters, verified by the anthropometric data measurement method using a digital scale for weight, a wall stadiometer for height, and an inelastic measuring tape for measuring body circumferences. It was observed that weight (p = 0.96), Body Mass Index (BMI) (p = 1.00), and circumferences (waist circumference, hip circumference, neck circumference, and wrist circumference) did not show significant differences after the intervention (p between 0.24 and 1.00). Expected Outcome 2: Verify the evolution of serum biochemical markers in the sample individuals before and after the intervention, verified by the biochemical data collection method. The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) and HOMA-BETA indices will be analyzed. A reduction in the HOMA-IR index is expected. Outcome 2: Verify the evolution of the HOMA-IR Index. Verified by the calculation method based on fasting glucose and insulin data. It was observed that the HOMA-IR index did not show a significant difference (p = 0.18) after the intervention.
