In his Mann Ki Baat radio programme, Prime Minister Narendra Modi highlighted the alarming rise in obesity, particularly among children.

• Call to Action: The PM urged citizens to reduce oil consumption by 10% each month to combat obesity and build a fit and healthy nation.
• Awareness Initiative: The PM  nominated prominent personalities to spread awareness and strengthen the fight against obesity through a social media campaign.

Scale of Obesity in India

• WHO Definition: Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health.
• National Family Health Survey  Data:
  • Women: Obesity increased from 20.6% (NFHS-4, 2015-16) to 24% (NFHS-5, 2019-21).
  • Men: Increased from 18.9% to 22.9% in the same period.
  • Urban vs. Rural: Obesity levels are significantly higher in urban areas.
• Abdominal Obesity: 40% of women and 12% of men had abdominal obesity based on waist circumference.
• Childhood Obesity: According to NFHS Data Children under 5 years are overweight, prevalence rose from 2.1% (2015-16) to 3.4% (2019-21).
• Projected Child Obesity: The projected prevalence of child obesity is 10.81% for children aged 5–9 years and 6.23% for those aged 10–19 years.

Health Risks Associated with Obesity

• Obesity: The World Health Organization (WHO) identifies obesity as a major risk factor for poor health and early death.
• Diseases: Linked to leading causes of mortality, including:
  • Cardiovascular disease
  • Diabetes
  • Several common cancers
  • Osteoarthritis

Disease Burden in India

• Diabetes: India has the highest number of diabetics globally, with an estimated 101 million cases.
• Cancer: Cases are projected to increase from 14.6 lakh (2022) to 15.7 lakh (2025) (ICMR-National Cancer Registry Programme).
• Cardiovascular Disease (CVD): One of the leading causes of death and disability in India. Affects Indians 10 years earlier compared to other populations.
• Non-Communicable Diseases (NCDs): Account for approximately 60% of all deaths in India.

Impact of Obesity

• Health Effects: Increased risk of early-onset NCDs and can impact school performance and quality of life.
• Psychosocial Consequences: Stigma, discrimination, and bullying.
• Long-Term Impact: Children with obesity are more likely to become obese adults. Higher risk of developing NCDs later in life.

Reasons for Obesity

• Unhealthy Diets: Increased consumption of ultra-processed foods high in sugars, unhealthy fats, and refined carbohydrates. Traditional diets being replaced with calorie-dense, nutrient-poor foods.
• Reduced Physical Activity Sedentary lifestyles due to office work and digital devices. Almost half of Indians are not physically active enough (The Lancet Global Health). 
  • Lack of safe pedestrian paths, cycling lanes, and green spaces discourages outdoor activity.
• Metabolic Disorders: Air pollution causes inflammation, increasing the risk of visceral adiposity and cardio-metabolic diseases.
•  Nutritional Challenges: Low-income households rely on carbohydrate-heavy diets (rice, wheat) due to affordability issues. Deficiency of iron and protein-rich foods (fruits, vegetables, pulses, dairy, and animal-based foods)
• Urban and Rural Divide: Currently more prevalent in urban, middle-class populations. Rising obesity among the rural poor, which may soon surpass other groups.

New Obesity Guidelines

• Limitations of BMI: It does not distinguish between fat and muscle mass and does not indicate fat distribution, especially abdominal fat, which is more harmful. 
  • Indians are genetically predisposed to accumulating abdominal fat, increasing the risk of metabolic syndrome (linked to diabetes, stroke, and heart disease).
• New Classification:
  • Stage 1: Increased adiposity without organ dysfunction.
  • Stage 2: Both physical and organ functions are affected.
• Abdominal Fat Distribution: Waist circumference and waist-to-height ratio to be used along with BMI. Body fat percentage measurement for a more accurate diagnosis.

Conclusion

Combating obesity requires lifestyle changes, awareness, and policy support. Collective action is key to a healthier future.
