体重在不知不觉中增加 许多人都有这样的感受： 步入职场后 身材似乎就难以维持 这究竟是为什么？ 武汉市第三医院从泽伟医生介绍，长期高强度工作会触发身体分泌过量皮质醇激素，大脑认为你受 到"虐待"，促使大脑进入"生存模式"，通过增加高热量食物摄入和脂肪囤积应对压力，是身体本能的反 应。 另据科普中国报道，实际上，皮质醇本身不是肥胖元凶，但它是一个重要的"助推器"和"搅局者"。 皮质醇是什么 皮质醇是肾上腺产生的一种糖皮质激素，是身体最为重要的"压力激素"。 在正常水平下，它能帮助我们控制血糖和血压、调节新陈代谢，还能帮助消炎，参与记忆的形成。一旦 压力超标、作息紊乱，它就会分泌过量，从"帮手"变成减肥路上的"拦路虎"。 皮质醇如何影响身体健康 1.激发进食欲望 压力过大会促使皮质醇分泌增多，从而刺激饥饿素释放。此外，频繁或长期的压力还可能引发焦虑和睡 眠障碍，进而抑制瘦素分泌，同时进一步推高饥饿素水平。 2.加速血糖向脂肪转化 皮质醇会加速糖原、脂肪和蛋白质的分解代谢，间接提升血液中葡萄糖的浓度。为应对升高的血糖，身 体会分泌更多"胰岛素"，将这些血糖转化为脂肪储存。 3.干扰激素平衡 长期皮质醇偏高不仅容易导 ...

Core Viewpoint - The article discusses the phenomenon of middle-aged weight gain, highlighting that it is a common issue influenced by lifestyle choices rather than metabolic changes as people age [4][18][30]. Group 1: Prevalence of Middle-Aged Weight Gain - Middle-aged weight gain is a widespread phenomenon, with studies indicating significant increases in Body Mass Index (BMI) from the age of 30 onwards [5][6][8]. - Research shows that the average BMI for men and women increases notably after the age of 30, with men reaching their peak BMI between 30 and 49 years [9][21]. - A study of 7,283 residents in Jiangsu found that waist circumference increases significantly during middle age, with men averaging 84.9 cm and women 77.5 cm by their 30s [12][13]. Group 2: Factors Contributing to Weight Gain - The article argues that middle-aged weight gain is not primarily due to metabolic slowdown but rather lifestyle factors such as diet, alcohol consumption, and physical inactivity [18][30][41]. - Increased alcohol consumption is noted, with men aged 40-65 drinking an average of over 160 times a year, contributing to weight gain [37][39]. - Sedentary lifestyles are highlighted, with research indicating that an increase of 1.5 hours of sitting time can lead to significant increases in BMI and waist circumference [41].

Group 1 - A significant percentage of employees experience weight gain after entering the workforce, with 84.8% of respondents in a survey reporting an increase in weight, and 33.2% becoming overweight [3] - The phenomenon of "overwork obesity" is prevalent, where increased work hours and stress lead to weight gain, creating a cycle of fatigue and further weight increase [4][12] - Sedentary lifestyles among office workers contribute to lower energy expenditure, making weight gain more likely, as evidenced by studies showing that low physical activity is linked to obesity [8][10] Group 2 - Psychological stress from workplace competition and pressure can lead to hormonal changes that increase appetite and fat accumulation, particularly in the abdominal area [14][19] - The consumption of high-calorie foods and beverages, such as late-night snacks and sugary drinks, exacerbates weight gain among employees, especially in industries with demanding work hours [24][30] - Addressing "overwork obesity" requires a focus on both increasing physical activity and improving dietary choices, as well as recognizing the biological predisposition to store fat [35][36]

Core Viewpoint - The article emphasizes that the decline in physical fitness associated with aging, particularly at the age of 35, is more related to lifestyle choices rather than age itself. Regular physical training can help mitigate or even reverse this decline [1][2][12]. Group 1: Age and Physical Fitness - A report indicates that job applicants aged 35 and above have increased by 14.9% in 2020, highlighting a societal perception of declining physical and mental capabilities in this age group [1]. - The article discusses how physical fitness can be maintained or improved through training, with examples of individuals achieving significant fitness milestones at advanced ages [2][12]. - It notes that the average adult loses 3-8% of muscle mass every decade after 30, and maximum heart rate and oxygen uptake decline by about 1% annually [12]. Group 2: Psychological Impact of Aging - The psychological effects of aging, particularly anxiety related to physical decline, are more pronounced than the actual physiological changes [5][6]. - The article mentions that many individuals in their mid-30s experience increased body awareness and concerns about weight gain, often attributing it to aging rather than lifestyle factors [5][10]. - Chronic pain issues, such as neck pain, are becoming more common among younger adults, indicating a shift in health concerns related to sedentary lifestyles [6][10]. Group 3: Lifestyle Factors and Health - Research indicates that BMI changes in adults are more closely linked to socioeconomic factors and lifestyle choices rather than age-related metabolic decline [8][10]. - The article highlights that unhealthy habits, such as irregular eating and increased alcohol consumption, contribute significantly to weight gain and health issues in the 35+ demographic [10][12]. - It emphasizes that maintaining a regular exercise routine can counteract the negative effects of aging and improve overall health and fitness levels [12][18].

Group 1: Age-Related Concerns - A report indicates a 14.9% year-on-year increase in job applications from individuals aged 35 and above, highlighting societal perceptions of declining physical and mental capabilities in this age group [4]. - The article notes that while aging can lead to some physical decline, many individuals experience issues like insomnia, back pain, and obesity due to accumulated poor lifestyle habits rather than age alone [5][8]. - The average adult loses 3% to 8% of muscle mass every decade after 30, and maximum heart rate and oxygen uptake decline by about 1% per year, but these declines can be mitigated through consistent physical training [19][26]. Group 2: Psychological Impact of Aging - The psychological effects of aging, such as anxiety about physical decline, are more pronounced than the actual physiological changes, with societal pressures contributing to this perception [8][10]. - The article discusses the phenomenon of "overwork obesity," where lifestyle factors like sedentary behavior and high stress levels exacerbate health issues, particularly in individuals over 30 [16][19]. Group 3: Importance of Physical Training - The article presents examples of individuals who have successfully improved their physical fitness well into their later years, demonstrating that age does not preclude the ability to achieve fitness goals [6][21]. - Regular exercise, including both aerobic and strength training, is recommended to counteract age-related declines and improve overall health, with the World Health Organization suggesting at least 150 minutes of moderate-intensity exercise weekly [20][26]. - The narrative encourages a shift in mindset, suggesting that maintaining a healthy lifestyle and exercise routine can lead to better physical and mental health outcomes, regardless of age [20][26].
