overweight
noun
We refer to overweight to a person’s weight which is above what is considered to be normal for our health. People who are overweight find it harder to move around and may have more health problems. You can be overweight for many reasons, but especially if you have an unhealthy diet.
When your weight is much higher than what is considered to be overweight, then you have a serious health condition (not a disease in the UK) known as obesity.
