Why in the News?
About 25% of men and women in India were overweight or obese in 2019-21, a 4% increase from 2015-16. Obesity is more common among women in South Indian states, Delhi, and Punjab, but it is rising faster among men.
What is the definition of “overweight” and “obese” based on BMI measurements in the National Family Health Survey?
- Overweight: BMI between 25.0 and 29.9. Example: A person who is 1.65 m (5’5″) tall and weighs 70 kg would have a BMI of 25.7, categorizing them as overweight.
- Obese: BMI of 30.0 or above. Example: A person who is 1.70 m (5’7″) tall and weighs 90 kg would have a BMI of 31.1, classifying them as obese.
- Calculation Formula: BMI = Weight (kg) ÷ (Height in meters)². Example: If a person is 1.60 m tall and weighs 60 kg, their BMI would be: BMI=601.6×1.6=23.4\text{BMI} = \frac{60}{1.6 \times 1.6} = 23.4BMI=1.6×1.660=23.4 (Healthy range).
When did the share of overweight and obese individuals in India significantly increase?
- Period of Increase (2015-16 to 2019-21): The National Family Health Survey (NFHS-5) recorded a significant rise in the share of overweight and obese individuals between 2015-16 (NFHS-4) and 2019-21 (NFHS-5).
- Increase in Overweight Individuals: Women: Increased from 15.5% in 2015-16 to 17.6% in 2019-21 (a rise of 2.1 percentage points). Men: Increased from 15.9% in 2015-16 to 18.9% in 2019-21 (a rise of 3 percentage points).
- Example: In Delhi, the proportion of overweight men and women was among the highest in the country during 2019-21.
- Increase in Obese Individuals: Women: Increased from 5.1% in 2015-16 to 6.4% in 2019-21. Men: Increased from 3% in 2015-16 to 4% in 2019-21. Example: Punjab recorded one of the sharpest increases in obesity among women during this period.
Which Indian states reported the highest increase in obesity levels?
- Northern States with Sharp Increases: Delhi and Punjab recorded the highest increase in obesity levels for both men and women between 2015-16 and 2019-21. Example: Delhi had the largest proportion of obese and overweight men in the country by 2019-21.
- Southern States with Persistent High Obesity Rates: Tamil Nadu, Kerala, Andhra Pradesh, Telangana, and Karnataka consistently reported high obesity levels, with a notable rise over the survey period. Example: In Kerala, a significant portion of the population—both men and women—crossed the obesity threshold by 2019-21.
- States with Accelerated Growth in Obesity: States in the South and North-West witnessed faster increases in obesity, reflecting a shift toward unhealthy dietary habits like increased consumption of fried foods and aerated drinks. Example: Punjab experienced a sharp increase in the share of obese women, making it one of the top states for rising obesity.

Way forward:
- Strengthen Multi-Sectoral Collaboration: Enhance coordination between health, education, and food regulatory bodies to implement comprehensive obesity prevention programs. Example: Integrate nutrition education in school curricula and expand community-based health screenings.
- Promote Sustainable Food Systems: Encourage the availability of affordable, nutritious foods and regulate ultra-processed foods through taxation and clear labeling. Example: Introduce subsidies for healthy food options and enforce strict advertising regulations for unhealthy products.
