Core Viewpoint - The article emphasizes the importance of a national strategy for weight management in response to the rising obesity rates in China, aiming for significant improvements in public awareness and skills related to weight management by 2030 [20]. Group 1: Current Obesity Trends - The prevalence of obesity among adults in China has reached 16.4%, with overweight rates of 11.1% and obesity rates of 7.9% among children aged 6 to 17 years, and 6.8% and 3.6% for children under 6 years respectively [4]. - There are notable demographic differences in obesity rates, with higher rates in males compared to females, and significant regional disparities between northern and southern China [5]. Group 2: Measurement and Assessment - Body Mass Index (BMI) is the standard measure for obesity, calculated as weight (kg) divided by height (m) squared, with specific thresholds for underweight, normal weight, overweight, and obesity [6][10]. - Waist circumference is also a critical indicator for central obesity, with specific thresholds for males and females [6]. Group 3: Weight Management Guidelines - The core goal of obesity treatment is to reduce excess body fat and lower the risk of obesity-related diseases [7]. - Regular assessments of weight loss progress and metabolic indicators are recommended every 3 to 6 months during weight loss [8]. - Weight loss targets should be stratified, with a recommendation for overweight and mildly obese individuals to aim for a 5%-15% reduction in body weight within 3 to 6 months [9]. Group 4: Dietary Approaches to Weight Loss - Various dietary strategies are outlined, including energy-restricted diets, very low-calorie diets, high-protein diets, intermittent fasting, low-carbohydrate diets, and low-fat diets, each with specific characteristics, target populations, clinical applications, and limitations [11]. - The article stresses the need for personalized dietary plans under the guidance of clinical nutritionists to ensure safety and effectiveness [11]. Group 5: Future Directions - The establishment of weight management centers in large hospitals is anticipated to enhance the treatment and management of obesity, emphasizing a multidisciplinary approach [12].
