Undernutrition to Over-nutrition: India’s double health crises Why Looking Healthy Isn't Always Being Healthy? Is the Weighing Scale Telling the Whole Story? When most people think of unhealthy weight, they picture someone who is visibly overweight. But what if a person appears slim, maintains a normal body weight, and still carries a high risk of diabetes, heart disease or fatty liver? This is the hidden reality affecting millions of Indians today. We are facing a silent epidemic where outward appearance often fails to reflect what is happening inside the body. The weighing scale alone is no longer a reliable indicator of good health. The Hidden Health Crisis in India Recent national studies reveal an alarming picture of India's metabolic health. According to the ICMR-INDIAB study, nearly 43% of Indian adults belong to the category of Metabolically Obese Non-Obese (MONO). These individuals have a normal Body Mass Index (BMI) but carry excess visceral fat and metabolic abnormalities that significantly increase their risk of chronic diseases. At the same time, the National Family Health Survey (NFHS-5) reports that nearly one in four Indian adults is overweight or obese, highlighting India's growing double burden of malnutrition—where undernutrition and obesity coexist. Why Are Even Lean People at Risk? Many Indians have what experts call the Asian Indian phenotype. Compared to many other populations, Indians tend to have lower muscle mass but store more fat around the abdomen and internal organs.This hidden fat, known as visceral fat, is metabolically active. It silently disrupts hormone function, promotes chronic inflammation, and increases insulin resistance long before noticeable symptoms appear.This is why a person can look perfectly healthy while serious metabolic damage is already underway. A Problem Affecting Every Generation The weight crisis is no longer confined to middle-aged adults. Childhood obesity is steadily increasing, setting the stage for lifelong health problems. Teenagers and young professionals are developing abdominal obesity due to sedentary lifestyles, prolonged screen time, unhealthy eating habits, and inadequate physical activity. As people enter their forties and fifties, these hidden metabolic disturbances often progress into diabetes, hypertension, abnormal cholesterol levels, and cardiovascular disease. What's Driving This Epidemic? Several factors are working together to fuel this growing health crisis: Genetic predisposition, making Indians more likely to store abdominal fat. A shift from traditional diets to ultra-processed foods, sugary beverages, and refined carbohydrates. Physical inactivity caused by desk jobs, digital entertainment, and reduced daily movement. Chronic stress and poor sleep, which further disrupt metabolism and hormone balance. Together, these lifestyle changes create the perfect environment for metabolic disease. The Health Risks Go Far Beyond Weight Unhealthy weight is much more than a cosmetic concern. Excess visceral fat increases the risk of: Type 2 Diabetes Heart disease and stroke Fatty Liver Disease (MASLD) Chronic Kidney Disease Sleep apnea Osteoarthritis Anxiety and depression Most of these conditions develop gradually and remain unnoticed until significant damage has already occurred. Protecting Your Metabolic Health The encouraging news is that metabolic health can be improved through early intervention. Regular physical activity, balanced nutrition, adequate protein and fibre intake, quality sleep, stress management, and routine health check-ups—including blood sugar, lipid profile, blood pressure, waist circumference, and liver function tests—can dramatically reduce future health risks. Early detection remains one of the most powerful tools for preventing chronic disease. The Take-Home Message Health is much more than a number on the weighing scale. A normal BMI does not always mean a healthy body, just as being overweight does not tell the complete story. True health lies in maintaining a healthy metabolism, strong muscles, and healthy body composition. Don't just watch your weight—understand your metabolic health. Because the most dangerous health problems are often the ones we cannot see.
