Kolkata, 14 October 2025:
Obesity, once considered a problem confined to older adults, is now alarmingly common among children and young people. Sedentary lifestyles, increasing gadget dependency, and reduced physical activity have made younger generations equally vulnerable. However, experts warn that obesity is not merely an issue of appearance — it is a serious health concern with far-reaching implications.
Dr. Torsha Chatterjee, Associate Consultant, Endocrinologist at Narayana Hospital, Barasat, emphasizes that Asians are particularly prone to accumulating visceral fat — the fat surrounding vital organs such as the liver, pancreas, and kidneys. “This type of fat is especially harmful as it interferes with insulin action, increasing the risk of diabetes,” she explains. For this reason, the body mass index (BMI) threshold for defining obesity is lower in Asians; while a BMI of 25 is considered overweight in other populations, for Asians, the cut-off is 23.
Although BMI remains a widely used tool, Dr. Chatterjee points out its limitations. “Athletes or muscular individuals may show a higher BMI without being obese, while others with normal BMI may carry significant visceral fat,” she says. Body fat assessment, which measures visceral fat more accurately, provides a clearer health picture.
Serious Risks Behind Obesity
Obesity is far more than excess body weight — it is a complex metabolic condition that increases the risk of numerous health issues, including dyslipidemia, hypertension, heart disease, kidney problems, insulin resistance, diabetes, gout, arthritis, and even depression. “Obesity is not just about willpower,” notes Dr. Chatterjee. “Hormonal and medical conditions such as hypothyroidism, Cushing’s syndrome, and polycystic ovary syndrome (PCOS) can cause or worsen weight gain.” In children, hypothalamic disorders can trigger uncontrollable hunger, making weight control challenging despite lifestyle efforts.
Lifestyle and Medical Interventions
Lifestyle modification remains the cornerstone of obesity management. A structured diet with controlled calories, adequate protein, and reduced intake of fats and salt is essential. “Creating a calorie deficit — consuming fewer calories than the body requires — is the most effective strategy for sustainable weight loss,” Dr. Chatterjee advises. Regular physical activity, including simple daily habits like walking more, taking stairs, and minimizing sedentary time, complements dietary control.
In recent years, medical therapies have provided new hope for patients struggling with obesity due to hormonal or metabolic factors. “Modern medications such as GLP-1 receptor analogues have shown promising results in weight reduction,” says Dr. Chatterjee. “When prescribed under proper medical supervision, these treatments can be both safe and effective.”
A Shift in Perception Needed
Dr. Chatterjee stresses that obesity must be recognized as a health condition rather than an issue of appearance. “Understanding its underlying causes, embracing sustainable lifestyle changes, and seeking timely medical help can prevent serious complications and improve overall quality of life,” she concludes.
