How do people become obese?

"Obesity" and being "obese" are words used by doctors to describe when a person (adult or child) is carrying extra weight on their body and that weight is being stored as fat. It is this extra fat that means that an obese person is more likely to suffer health problems than a person who is a healthy weight.

Our bodies do need a small amount of fat to be healthy. However, if we eat too much food (particularly fatty and sugary foods), the body has to store the extra energy in fat cells underneath our skin.

Sometimes, people eat the right types and the right amount of food, but they are not active enough. If we eat more than we burn up by being active and exercising, then the body is forced to store the extra energy by making it into fat, which is stored in the fat cells.

Having a tendency to put on weight does run in families. People who are overweight are likely to have genes that mean that it is easier for them to put on weight if they live an unhealthy lifestyle. However, if they live a healthier lifestyle it is entirely possible for them to avoid being overweight.

MEND helps children and families make changes to their eating and activity habits which allow them to manage their weight safely. Our Programmes help children grow up to lead healthier lives that continue into adulthood.
