Core Viewpoint - The article emphasizes the benefits of GLP-1 medications, particularly for the elderly, highlighting that weight loss can significantly improve mobility, balance, and overall health, potentially allowing older adults to live more independently [2][6]. Group 1: Benefits of GLP-1 Medications for the Elderly - A significant portion of the elderly population is not utilizing GLP-1 medications, with only 9% of those aged 65 and older reporting usage compared to 19% in the 50-64 age group [4]. - Weight loss from GLP-1 medications can enhance mobility and reduce the need for assistive devices like wheelchairs or canes, as evidenced by patients who have experienced improved conditions post-weight loss [6][7]. - The reduction in weight can alleviate joint stress, with each pound lost equating to a reduction of 2 to 4 pounds of pressure on the joints, thus improving flexibility and reducing pain [6]. Group 2: Medical Considerations and Treatment Approaches - Physicians recommend a comprehensive approach for elderly patients, including consultations with nutritionists and physical rehabilitation to ensure safe engagement in physical activities [5]. - Dosage adjustments for GLP-1 medications may be necessary for elderly patients who are on multiple medications, ensuring safety and efficacy [5]. Group 3: Mechanism of Action of GLP-1 Medications - GLP-1 medications, such as semaglutide, mimic the hormone GLP-1, which helps lower blood sugar and promotes a feeling of fullness, thus aiding in weight management [9][11]. - These medications not only suppress appetite but also alter the body's metabolic response to food intake, indicating that obesity is a complex metabolic disease rather than merely a behavioral issue [11].

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].

Core Insights - The article discusses the rising global obesity rates and the challenges of weight loss and maintenance, highlighting the role of sugar consumption and the controversial use of sweeteners in weight management [6][11]. Study Findings - A recent study published in *Nature Metabolism* provides new evidence on the effectiveness of sweeteners in weight management, showing that their reasonable use can help overweight or obese adults maintain weight loss while positively affecting gut health [7][11]. - The study involved 341 adults and 38 overweight or obese children over a one-year period, with participants initially undergoing a two-month low-energy diet before entering a ten-month weight maintenance phase [9]. - Participants were divided into two groups: one used sweetener-containing products to replace high-sugar foods, while the other maintained their usual sugar intake, both adhering to a diet where sugar contributed less than 10% of total energy [9]. Weight Maintenance Results - After one year, the sweetener group maintained an average weight loss advantage of 1.6 kg compared to the control group, with the weight difference consistently ranging from 1.0 to 2.1 kg throughout the study [9]. - Participants who strictly followed the intervention showed an even greater weight loss advantage of up to 3.7 kg [9]. Gut Health Benefits - The study also revealed that the sweetener group experienced significant increases in beneficial gut bacteria associated with short-chain fatty acids, along with enhanced microbial activity related to methane production and various fermentation processes [9][11]. - Metabolic pathway analysis indicated that the sweetener group exhibited more active beneficial metabolic activities, including the degradation of aromatic compounds and vitamin synthesis [9]. Safety Monitoring - The research team monitored the safety of sweetener use, noting that while the sweetener group reported more gastrointestinal discomfort, serious adverse events were rare and not directly linked to the intervention [11]. Conclusion - The findings support the use of sweeteners as a viable strategy for weight management and gut health improvement, offering hope for individuals struggling with weight regain [11].

Core Viewpoint - The article discusses the importance of basal metabolic rate (BMR) in weight management and how increasing BMR can facilitate weight loss without changing diet or exercise habits [8][11]. Summary by Sections Understanding Basal Metabolic Rate (BMR) - BMR accounts for approximately 45% to 70% of daily energy expenditure, essential for maintaining vital functions like heartbeat and respiration [8]. - The article provides an example comparing two individuals with different BMRs, illustrating how a higher BMR leads to greater daily calorie expenditure [8][12]. Estimating BMR - The article outlines methods to estimate BMR, including a formula based on weight, height, age, and gender, with examples provided for clarity [9][10]. - It mentions that while precise measurement methods exist, they are often impractical for everyday use, leading to reliance on estimations [9]. Factors Influencing BMR - BMR is influenced by various factors such as height, age, gender, genetics, hormones, and body composition, with a focus on muscle mass as a modifiable factor [14]. - The article emphasizes that while some factors cannot be changed, increasing muscle mass through exercise is a viable strategy to enhance BMR [14]. Strategies to Increase BMR 1. **Scientific Exercise**: Engaging in resistance training and aerobic exercises can increase muscle mass and subsequently BMR, with recommendations for a balanced workout routine [15]. 2. **High-Quality Protein Intake**: Consuming adequate protein helps maintain muscle mass during weight loss, which is crucial for sustaining a higher BMR [17]. 3. **Balanced Diet**: Avoiding extreme dieting is essential, as it can lower BMR; a balanced intake of carbohydrates, proteins, and fats is recommended [18]. 4. **Proper Hydration**: Staying hydrated supports metabolic processes, with a suggestion to drink around 2000 milliliters of water daily [20]. Conclusion - The article concludes that while increasing BMR can aid in weight loss, it must be coupled with a reasonable diet and regular exercise to be effective [20].
