All subjects were given a diabetes diet and activity guidance, understood the basic information about this RCT and their medical history, and provided information on their weight and waist circumference. All patients were instructed to visit the hospital every 4 weeks, and the patients’ body weight and waist circumference were recorded during each visit. Blood and fecal samples were taken at the start (month 0) and end (month 3) of the trial to monitor changes in relevant clinical parameters and the fecal microbiome and metabolome.
