Core Viewpoint - The Chengdu Third People's Hospital's obesity and metabolic disease center has seen a significant increase in patients seeking weight loss solutions, indicating a shift towards proactive health management rather than reactive treatment after health issues arise [8][11]. Group 1: Patient Demographics and Trends - The obesity and metabolic disease center has completed a total of 6,835 weight loss surgeries, with a notable increase in patients who are overweight but not yet experiencing health complications [6][8]. - Approximately 40% of the new outpatient visits are from overweight patients who are taking the initiative to manage their weight before developing related health issues [8]. - The center emphasizes that obesity is not solely determined by appearance, as many patients with normal weight may still suffer from metabolic disorders [11]. Group 2: Health Implications and Treatment - The center's approach includes a comprehensive analysis of body composition and metabolic rates, with over 50 data points used to assess obesity scientifically [10]. - Current statistics indicate that 34.3% of the population is overweight and 16.4% is obese, meaning over 700 million people in China are affected by weight issues [11]. - The center reports that 80% to 90% of obesity-related complications can be alleviated through weight loss, with significant improvements in conditions like type 2 diabetes and hypertension [12][15]. Group 3: Psychological and Lifestyle Changes - The treatment process at the center not only focuses on physical health but also addresses the psychological aspects of obesity, with many patients experiencing emotional relief post-surgery [13][15]. - Patients are encouraged to adopt sustainable lifestyle changes, as relying solely on medication for weight maintenance is often ineffective [14]. - The concept of "rebirth" is prevalent among patients, who express a desire to regain control over their lives and health through weight loss [15].

Core Viewpoint - The emergence of GLP-1 receptor agonists, such as semaglutide and tirzepatide, has transformed obesity treatment, enabling rapid weight loss of 15%-20%. However, approximately 50% of obese patients discontinue these medications within a year, leading to significant weight regain and the need to understand post-medication weight changes [6][10]. Research Background: Current Status and Challenges in Obesity Treatment - Nearly 2 billion adults globally are affected by overweight or obesity, which significantly increases the risk of various complications and premature death. Behavioral weight management programs (BWMP) have traditionally been the cornerstone of obesity treatment, focusing on low-calorie diets and increased physical activity. The introduction of new weight loss medications is changing the treatment landscape [6][5]. Research Methodology: Rigorous Evidence Synthesis - The research team systematically reviewed seven databases and trial registries, including 37 studies with 9,341 participants. The average treatment duration was 39 weeks, with an average follow-up of 32 weeks post-medication. Various weight loss medications were analyzed, focusing on both weight changes and cardiovascular metabolic markers [8][7]. Key Findings: Dual Regain of Weight and Health Indicators - On average, participants lost 8.3 kg during medication use, but weight began to rebound post-discontinuation at a rate of 0.4 kg per month, leading to a full return to baseline weight in approximately 1.7 years. Newer medications like semaglutide and tirzepatide showed even faster rebound rates of 0.8 kg per month, returning to baseline in about 1.5 years. Cardiovascular metabolic benefits also diminished within 1.4 years after stopping medication [10][4]. Comparative Analysis: Differences Between Medication and Behavioral Interventions - While medication resulted in a greater average weight loss of 3.2 kg, the rebound rate was significantly faster compared to behavioral interventions, which had a rebound rate of only 0.1 kg per month, taking about 3.9 years to return to baseline weight. This indicates that behavioral interventions may equip participants with sustainable weight management skills, unlike medication, which primarily reduces hunger and increases satiety [12][14]. Insights and Recommendations: Rational Perspective on Weight Loss Medications - The research emphasizes that obesity is a chronic relapsing disease that may require long-term treatment for sustained health benefits. Evidence suggests that continuous use of semaglutide for four years can successfully maintain weight loss. Given the high discontinuation rates of weight loss medications, it is crucial to recognize that these drugs alone may not suffice for long-term weight control. Sustainable healthy lifestyle changes remain fundamental in obesity prevention and treatment [15][16].

Core Viewpoint - The article discusses the rising global obesity rates and highlights the potential of cysteine-restricted diets as an intervention method, focusing on the molecular mechanisms behind rapid weight loss induced by cysteine limitation [8][9]. Research Background and Purpose - Background: The global obesity prevalence is increasing, and cysteine-restricted diets are gaining attention as a potential intervention method. Cysteine is a crucial precursor for synthesizing glutathione (GSH) and coenzyme A (CoA), but the specific effects of cysteine limitation on body weight and its regulatory mechanisms remain unclear [8]. - Purpose: The study aims to explore the molecular mechanisms behind rapid weight loss induced by cysteine restriction using mouse experiments, providing new targets for obesity treatment [9]. Research Methods - Study Design: The research utilized Cse gene knockout (KO) and wild-type (WT) mice, administering cysteine-restricted diets (no-Cys) and other essential amino acid-restricted diets, combined with metabolic cage monitoring and comprehensive transcriptomic and metabolomic analyses [10]. - Data Sources: The study collected metabolic products from mouse liver, muscle, fat tissues, serum, and urine, with sample sizes ranging from 3 to 9 mice per experimental group [11]. - Research Variables: The focus was on cysteine intake, body weight changes, and metabolic indicators such as GSH, CoA, and inflammatory factors [12]. - Analysis Methods: Techniques included RNA sequencing, LC-MS metabolomics, immunohistochemistry, Western blotting, and indirect energy metabolism measurement [13]. Research Results 1. Cysteine deficiency leads to rapid and reversible weight loss: Cse KO mice on a no-Cys diet experienced a weight loss of up to 30% within one week, significantly exceeding other essential amino acid-restricted groups. Weight returned to baseline upon resuming normal diet, indicating that weight loss was primarily due to cysteine deficiency [14]. 2. Metabolic reprogramming promotes fat consumption and browning: The no-Cys diet reduced the respiratory exchange ratio (RER) and total fat mass, with a notable increase in UCP1-positive cells in white adipose tissue, indicating brown fat characteristics. Liver transcriptomic results showed activation of fatty acid oxidation pathways and suppression of fat synthesis genes [16]. 3. Integration of stress pathways and oxidative stress: Cysteine restriction activated integrated stress response (ISR) and oxidative stress response (OSR), significantly increasing serum levels of GDF15 and FGF21. Deletion of Gdf15 or Fgf21 slowed weight loss, suggesting their roles in metabolic adaptation regulation [19]. 4. CoA reduction leads to decreased metabolic efficiency: The no-Cys diet lowered liver CoA levels, resulting in increased urinary excretion of TCA cycle intermediates, indicating impaired mitochondrial oxidative phosphorylation capacity [20][21]. 5. Tissue-specific regulation of energy metabolism pathways: ISR and OSR-related genes were significantly upregulated in the liver, while muscle primarily activated oxidative stress pathways, and adipose tissue emphasized lipolysis and browning responses, demonstrating coordinated regulation across multiple tissues for systemic metabolic remodeling [23]. Research Conclusion and Limitations - Conclusion: Cysteine restriction promotes rapid weight loss by depleting GSH and CoA, activating stress responses, enhancing fat oxidation, reducing metabolic efficiency, and stimulating creatine cycling compensation. This physiological process is reversible and offers new insights for obesity treatment [27]. - Limitations: The study has not assessed the safety of cysteine restriction in humans, and the long-term effects on other organs and gender differences remain unexplored, necessitating further validation of the underlying mechanisms [28]. Future Research Directions - Future studies should evaluate the weight loss effects and safety of cysteine restriction in primates, analyze the impact of cysteine deficiency on gut microbiota, and explore the molecular mechanisms of gender differences in response to cysteine restriction to advance personalized intervention strategies [29].
