IELTS Task 2 health essay: Band 9 sample & how to write it

Rising rates of obesity have become a pressing public-health concern in many parts of the world. This essay will examine the principal causes of this trend before proposing several measures that governments and individuals could take to reverse it.

The causes are largely rooted in modern lifestyles. The most significant is diet: cheap, heavily processed food high in sugar and fat is now widely available and aggressively marketed, while home cooking has declined. A second factor is the fall in physical activity; sedentary office work, reliance on cars, and screen-based leisure mean that far fewer people are active in daily life than in previous generations. Together, a higher calorie intake and lower energy expenditure inevitably lead to weight gain.

Fortunately, a range of measures could address the problem. Governments could regulate the food industry — for instance, by taxing sugary drinks, requiring clearer labelling, and restricting junk-food advertising aimed at children. Equally important is making physical activity easier and more appealing, through investment in parks, cycle lanes and affordable sports facilities. At an individual level, public-education campaigns can help people understand nutrition and take responsibility for their own habits.

In conclusion, the rise in obesity stems chiefly from poor diet and increasingly inactive lifestyles. Through a combination of sensible regulation, better infrastructure and public education, this worrying trend can realistically be slowed and even reversed.
