Official title
The Effect of Inulin on Cardiometabolic Risk Factors in Individuals Using Glucagon-like Peptide-1 Receptor Agonists (GLP-1 RA) Medications for Weight Loss: a Randomized Double-blind Controlled Trial
Overview
The goal of this double-blind randomized placebo-controlled supplement study is to investigate if the supplement of inulin (prebiotics, 10 grams per day) has beneficial effects on cardiometabolic risk factors in overweight or obese individuals receiving glucagon-like peptide-1 receptor agonists (GLP-1 RA) medications for weight loss.
Detailed description
The goal of this double-blind randomized placebo-controlled supplement study is to investigate if the supplement of inulin (prebiotics, 10 grams per day) has beneficial effects on cardiometabolic risk factors in overweight or obese individuals receiving glucagon-like peptide-1 receptor agonists (GLP-1 RA) medications. Approximately 600 overweight or obese individuals using GLP-1 RA medications for weight loss will be enrolled. All participants will provide informed consent before randomization. Eligible individuals must be obese or be overweight with at least one body weight-related complications, and have been using GLP-1 RA medications at the time of enrollment for at least 3 months and plan to continue using them in the next 6 months. Eligible participants will be randomly assigned to inulin intervention or placebo group. Randomization will be computed within study center, age and sex groups. The intervention will last for 4 months. Questionnaire data and bio-samples will be collected before the start of intervention and at the end of the intervention. The primary outcomes are lipid levels measured in bio-samples. Data on secondary outcomes will be obtained through biomarker measurement and questionnaires.
Interventions
- Dietary supplement inulin (prebiotics)
The intervention dose is 10 grams per day. The intervention will last for 4 months. - Dietary supplement Placebo Comparator: maltodextrin
The dose is 10 grams per day for 4 months.
Primary outcome measures
- change in concentrations of blood lipid levels in millimole per liter (mmol/L). [Time frame: From enrollment to the end of intervention at 4 months]
Secondary outcome measures (12)

- change in level of insulin resistance [Time frame: From enrollment to the end of intervention at 4 months]
- change in body weight in kilograms (kg) [Time frame: From enrollment to the end of intervention at 4 months]
- change in body fat percentage (%) [Time frame: From enrollment to the end of intervention at 4 months]
- change in waist circumference in centimeters (cm) [Time frame: From enrollment to the end of intervention at 4 months]
- change in level of gut microbiota abundance [Time frame: From enrollment to the end of intervention at 4 months]

- change in estimated glomerular filtration rate (eGFR) in milliliter per minute per 1.73 square meters (mL/min/1.73 m²) [Time frame: From enrollment to the end of intervention at 4 months]
- change in concentrations of liver function markers in units per liter (U/L) [Time frame: From enrollment to the end of intervention at 4 months]
- change in level of C-reactive protein (CRP) in milligram per liter (mg/L) [Time frame: From enrollment to the end of intervention at 4 months]
- change in blood pressure in millimeters of mercury (mmHg) [Time frame: From enrollment to the end of intervention at 4 months]
