Overweight happens when a person has too much body fat. It is a health problem affecting people allover the world. In fact, more than one billion people worldwide are suffering from overweight.

Here are two main reasons why overweight occurs. Firstly, eating too much unhealthy food high in sugar and fat can lead to weight gain. Lack of physical activity is another factor. When we don't move our body enough, excess fat can accumulate.

Overweight can harm us in many ways. First, it raises the risk of severe health problems, like high blood pressure, heart disease, and even some types of cancer. It can also affect our self-confidence and mental health. Lastly, it forces our bodies to work extra hard to carry the extra weight, making everyday activities harder.
