Eksperimentel: 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.
Andre navne:
Semaglutide 1.0 mg subcutaneous injection once weekly
Andre navne:
Daily caloric intake will be individualized based on physical activity level: 25 kcal/kg/day for individuals with light-to-moderate physical activity and 30 kcal/kg/day for those with heavy physical activity.
