简要总结
This is a randomized, prospective clinical trial investigating metabolic syndrome in overweight or obese Chinese individuals. The study aims to evaluate the efficacy of a structured intensive lifestyle intervention program in achieving significant weight reduction (targeting 15% weight loss) and promoting metabolic syndrome remission. Additionally, the research will explore the potential mechanisms underlying these therapeutic effects. Furthermore, this study enables phased presentation of the findings.
详细描述
Background:
Metabolic syndrome is a global public health concern, with prevalence rates ranging from 10% to 84% across different populations. It is strongly associated with multiple chronic non-communicable diseases, including type 2 diabetes, cardiovascular diseases, non-alcoholic fatty liver disease, polycystic ovary syndrome, and certain cancers. Notably, obesity plays a central role in the development of metabolic syndrome, and substantial evidence supports the benefits of significant weight loss in improving its components. Currently, there is a lack of research on lifestyle interventions aimed at weight loss to alleviate metabolic syndrome in affected populations.
Study Design:
This study is a single-center, prospective, randomized controlled trial. Metabolic syndrome (MetS) subjects aged 18-60 years were enrolled and randomly assigned to either an intensive lifestyle intervention group (a low-carbohydrate diet combined with physical exercise, target weight loss of 15%) or a conventional lifestyle intervention group ( energy-restricted diet combined with physical exercise, target weight loss of 7%). Participants underwent a 5-month weight-loss intervention (with monthly follow-ups) followed by a 7-month weight-maintenance phase (with follow-ups every 2 months). During the follow-up period, anthropometric and laboratory parameters were regularly monitored.

结局指标
主要结局
The proportion of participants achieving 15% weight loss from baseline
时间窗: 12 months
The proportion of participants achieving 15% weight loss from baseline
The remission rate of metabolic syndrome
时间窗: 12 months
Participants are considered to have achieved metabolic syndrome remission when they meet ≤2 of the following 5 diagnostic criteria: 1. Waist circumference ≥85 cm (men) / ≥80 cm (women); 2. Fasting triglycerides ≥1.7 mmol/L or current lipid-lowering therapy; 3. HDL cholesterol \<1.04 mmol/L (men) / \<1.30 mmol/L (women); 4. Systolic BP ≥130 mmHg and/or diastolic BP ≥85 mmHg, or diagnosed hypertension with antihypertensive treatment; 5. Fasting glucose ≥5.6 mmol/L, or diagnosed type 2 diabetes with glucose-lowering treatment. Remission is defined as sustained resolution of ≥3 criteria.
