Effects of Inulin on Cardiometabolic Risk Factors in Individuals Using Glucagon-like Peptide-1 Receptor Agonists (GLP-1 RA ) Medications for Weight Loss

1 de junho de 2026 atualizado por: An Pan, Huazhong University of Science and Technology

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

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.

Descrição detalhada

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.
