Group 1: Current Situation of Overweight and Obesity - The report indicates that the overweight and obesity rates among Chinese youth aged 6-17 have reached 19%, while the adult population's rate stands at 50.7% [5]. - Over the past 15 years, the obesity rate among adolescents has surged by 12 times, with workplace-related obesity and elderly obesity becoming more prevalent [5]. - Chronic diseases related to obesity, such as hypertension, diabetes, and cardiovascular diseases, account for over 70% of the national disease burden, with direct medical expenses exceeding 240 billion yuan annually [5]. Group 2: Obesity Assessment Criteria - Obesity is primarily assessed using BMI and waist circumference metrics, with a normal BMI range defined as 18.5 to 23.9 [6]. - Waist circumference is a critical indicator of abdominal obesity, with men exceeding 90 cm and women exceeding 85 cm at risk [8]. - Other common obesity assessment indicators include body fat percentage and waist-to-hip ratio, with specific thresholds indicating obesity risk [9]. Group 3: Consequences of Obesity - Obesity is linked to increased body weight and is closely associated with blood sugar and lipid levels, leading to insulin resistance and elevated blood sugar, which can progress to diabetes [10]. - It is also a significant risk factor for dyslipidemia, with excess body fat leading to abnormal blood lipid levels [11]. - Regular monitoring of blood sugar and lipid levels is essential, even for individuals with a normal BMI, to ensure metabolic health [12]. Group 4: Multi-Dimensional Weight Management Strategies - Enhancing basal metabolic rate (BMR) through muscle gain and regular exercise is crucial for effective weight management [13]. - B vitamins play a vital role in energy metabolism, influencing both basal and activity metabolic rates, and their deficiency can lead to metabolic disorders [14]. - Reducing exposure to toxic elements and endocrine disruptors is important for maintaining metabolic balance and preventing obesity [15]. Group 5: Gut Health and Digestion - A healthy gut is essential for nutrient absorption and waste elimination, with gut microbiota playing a significant role in weight regulation [17]. - Hormonal balance, regulated by the endocrine system, is critical for metabolism and energy management, with disruptions potentially leading to obesity [17]. - A balanced diet, incorporating various nutrients, is fundamental for effective weight management and healthy weight loss [17].
