Delhi's air quality worsens as pollution may contribute to weight gain

Air quality in Delhi has worsened significantly, with several areas recording an Air Quality Index (AQI) above 400, indicating 'severe' pollution. Anand Vihar reached an AQI of 433, while other areas also reported very poor air quality levels. This decline in air quality follows the Diwali celebrations and has raised concerns about health impacts beyond respiratory issues. Research suggests that air pollution may contribute to weight gain through mechanisms like inflammation, insulin resistance, and hormonal imbalances. Poor air quality can also lead to reduced physical activity and changes in gut microbiota, both of which may promote weight gain. Increased oxidative stress and brain inflammation further disrupt appetite regulation, potentially leading to overeating.
