The Efficacy and Safety of Puerarin in Obesity Treatment

This randomized controlled trial aims to evaluate the therapeutic efficacy of puerarin intervention in weight management and metabolic regulation among obese populations. The study will systematically address two primary endpoints: 1) The capacity of puerarin to induce clinically significant body weight reduction in individuals with BMI ≥30 kg/m²; 2) Its modulatory effects on postprandial lipid metabolism as measured by serum lipids and quantitative fecal lipid excretion analysis. Secondary outcomes focus on puerarin's pleiotropic effects, including continuous glucose monitoring-derived glycemic parameters and indirect calorimetry-assessed resting metabolic rate. Secondary exploratory objectives include investigating puerarin's potential mechanisms of action through continuous glucose monitoring and indirect calorimetry measurements to assess glycemic variability and resting energy expenditure, respectively. Participants will be randomized into two parallel groups: the intervention group receiving daily oral puerarin injection (75 mg/day, dissolved in 100 mL of 0.9% sodium chloride solution) and the control group receiving matched blank 100 mL of 0.9% sodium chloride solution, both administered double-blind for 6 consecutive months. Primary efficacy endpoints (body weight, waist circumference, lipid profile) and safety monitoring (adverse events, hematological/ biochemical parameters) will be assessed at baseline, 1, 3, and 6 months post-intervention.
