Exercise-Targeted Smart Lifestyle Management

This study aims to conduct a randomized controlled clinical trial among occupational populations with overweight/obesity and metabolic syndrome. By implementing a healthy dietary pattern with energy restriction and personalized exercise training interventions, we aim to investigate their effects on improving metabolic syndrome.

Inclusion criteria

• Aged between 20 and 60 years.
• Overweight or obese, with a Body Mass Index (BMI) ≥ 24 kg/m² and < 40 kg/m².
• Patients with impaired metabolic parameters regarding glucose, lipids, and blood pressure，meet at least two of the following criteria:

• Central obesity: Waist circumference ≥ 90 cm for males or ≥ 85 cm for females.
• Hyperglycemia: Fasting plasma glucose (FPG) ≥ 6.1 mmol/L, or 2-hour plasma glucose ≥ 7.8 mmol/L during an oral glucose tolerance test (OGTT), and/or currently receiving treatment for previously diagnosed diabetes.
• Hypertension: Blood pressure ≥ 130/85 mmHg, and/or currently receiving treatment for previously diagnosed hypertension.
• Elevated fasting triglycerides (TG): ≥ 1.7 mmol/L.
• Reduced fasting high-density lipoprotein cholesterol (HDL-C): < 1.04 mmol/L.

Exclusion criteria

• History of cardiovascular or cerebrovascular disease, or in the acute phase, including: angina pectoris, myocardial infarction, coronary revascularization surgery, stroke (ischemic or hemorrhagic, including transient ischemic attack), symptomatic peripheral artery disease requiring surgery or diagnosed via angiographic techniques, ventricular arrhythmias, uncontrolled atrial fibrillation, congestive heart failure (New York Heart Association class III or IV), hypertrophic cardiomyopathy, history of aneurysm with diameter ≥ 5.5 cm, or history of aneurysm surgery.

• Current use of systemic corticosteroids.
• Current use of weight-loss medications.
• Currently participating in another randomized clinical trial.
• Patients with acute infection or inflammation (e.g., pneumonia) may -participate 3 months after resolution of the condition.
