India, July 1 -- Obesity is no longer just a cosmetic issue. With over 80 million affected, including nearly one crore aged 5 to 19, it is one of India's biggest lifestyle health challenges. The numbers are a stark wake up call. Traditionally, obesity is measured by Body Mass Index (BMI). A BMI over 25 is considered obese in India due to genetic predispositions and abdominal fat risks. According to recent NFHS-5 data, nearly 44% of Indian men and 41% of women fall into the overweight or obese category. Urban India is particularly affected, with 70% of the population now classified as overweight or obese. Behind the bulge is a mix of unhealthy food choices, sedentary lifestyles, stress, and emotional eating. Obesity is linked to a host of health complications like type 2 diabetes, heart disease, hypertension, certain cancers, and even psychological issues like anxiety, low self-esteem, and social stigma. But here's the good news: obesity is both preventable and manageable. The formula isn't complex - small, sustainable lifestyle changes make all the difference. Start with your plate. Opt for fibre-rich, whole foods and cut out sugary drinks, processed snacks, and late-night meals. Move more - aim for at least 30 minutes of physical activity daily. Sleep well, manage your stress, and limit screen time. For those struggling, holistic solutions like personalised diet and exercise plans, portion control, behavioural therapy, and regular BMI monitoring can turn the tide. India's obesity crisis can no longer be brushed under the rug. It's time to shift focus from treatment to prevention starting from homes, schools, and communities. Because a healthier India starts with healthier choices, one day at a time. Prof (Dr) M Wali, MD FRCP FACC (USA) is a senior consultant at Sir Ganga Ram Hospital, New Delhi...
