Did you know that almost 400 million children around the world will be living with obesity by 2035? That’s 100% more than in 2020. Childhood obesity can profoundly affect physical, social and emotional wellbeing, academic performance and self-esteem. This often carries through to adolescence and into adulthood.

Young people are being let down by systemic factors – like aggressive food marketing and unequal access to healthcare – that make it difficult to lead healthy lives. It’s time they were involved in developing solutions for a better future.

Have you ever thought about the language people use when discussing obesity? It is common to see obesity talked about in a negative way which risks reinforcing stereotypes, simplifying the causes of obesity and contributing to weight stigma. There are also many misconceptions about obesity – like the idea that obesity is the fault of the individual.

Use our resources to understand the roots of obesity, take part in collaborative action, and learn how to talk about the topic in an inclusive way with friends, family, and youth groups.
