Impact of Dietary Fiber as Prebiotics on Intestinal Microbiota in Obese Thai Children

This study evaluates the changes in gut microbiota composition, body fat, children's eating behaviors, plasma amino acids, and satiety hormones (Peptide-YY and GLP-1) after a 6-month period in obese Thai children. A total of 165 children, aged 7 to 15 years with a Body Mass Index (BMI) ≥ median + 2 standard deviation (SD), were randomized into three groups: Group A (intervention group) received inulin daily. Group B received an isocaloric maltodextrin placebo. Group C received dietary fiber advice aimed to match age-appropriate recommendations.
