based on an overall assessment of feasibility and strategic considerations

This study aims to evaluate the effects of the combined formula WM Formula, used as a dietary supplement, with a focus on improvements in glycemic and lipid parameters, body composition, and gut microbiota profiles.

This study is a single-center, randomized, double-blind, placebo-controlled human clinical trial designed to evaluate the potential effect of the WM Formula composite supplement on body weight. Eligible participants will be adults aged 18 years or older, screened based on waist circumference or body fat percentage.

Participants will be randomly assigned to one of two groups: one receiving the combined formula WM Formula, and the other receiving a placebo. Each group will take either the WM Formula or placebo, and undergo regular assessments throughout the 4-week study period. Physiological parameters (e.g., height, weight, blood pressure, BMI) and biochemical markers (including liver and kidney function, lipid profile, and blood glucose levels) will be collected at baseline (Week 0), Week 2, and Week 4. In addition, participants will complete appetite assessment questionnaires and other surveys to evaluate changes in appetite and gastrointestinal symptoms.
