21 maggio 2026 aggiornato da: An Pan, Huazhong University of Science and Technology

The Effect of Inulin on Cardiometabolic Risk Factors in Individuals Using 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, 10g/day) has beneficial effects on cardiometabolic risk factors in overweight or obese individuals receiving GLP-1 RA medications for weight loss.

Panoramica dello studio

Descrizione dettagliata

The goal of this double-blind randomized placebo-controlled supplement study is to investigate if the supplement of inulin (prebiotics, 10g/day) has beneficial effects on cardiometabolic risk factors in overweight or obese individuals receiving 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.

Individuals meeting any of the following criteria will be ineligible:

1. Currently using non-GLP-1 RA medications for weight-loss, or have undergone or plan to undergo within the next 4 months, weight-loss procedures such as bariatric surgery, acupuncture thread embedding and liposuction; 2. Long-term user of prebiotics or probiotics (excluding fermented dairy products such as yogurt); 3. Allergic or intolerance to inulin-type substances; 4. Have participated in in other clinical trials within the past 3 months or are currently participating in other clinical trials; 5. Plan to be pregnant within the next year, are currently pregnant, or are breastfeeding; 6. Deemed unsuitable for participation by the investigator's judgment.

Lasso di tempo: From enrollment to the end of intervention at 4 months
Description: change in concentration of glycosylated Hemoglobin A1c (HbA1c) from baseline to 4-month visit
From enrollment to the end of intervention at 4 months
insulin resistance
Lasso di tempo: From enrollment to the end of intervention at 4 months
Change in HOMA-IR (homeostatic model assessment of insulin resistance) and adipo-IR (adipose tissue insulin resistance index) from baseline to 4-month visit. HOMA-IR will be calculated based on fasting glucose and fasting insulin. Adipo-IR will be estimated using fasting insulin and fasting free fatty acids.
