Experimental: Intervention group
A comprehensive intervention combining fecal microbiota transplantation, calorie-restricted diet, and glucagon-like peptide-1 receptor agonist.
|
Donor Selection: Healthy lean donors with BMI <23 kg/m² will be selected following rigorous health screening. Capsule Preparation: Donor fecal samples will be homogenized, filtered to remove debris, lyophilized, and encapsulated in enteric-coated capsules. Oral FMT capsule dosage: 10 capsules per dose, once daily, for 6 consecutive days each month.
