Obesity is an increasingly serious public health issue worldwide, including China. Commonly recommended treatments for overweight and obesity have drawbacks including psychological and physiological side effects, lack of cost-effectiveness, and difficulty in long-term weight loss maintenance. Traditional Chinese Medicine (TCM) can be a better alternative given its wide acceptance in China. Thus, this study aims to provide a comprehensive picture of the efficacy of TCM in reducing body weight and BMI by comparing it with other treatments and ranking various TCM therapies, and hopefully to reveal the potential of TCM.
