Why are so many people not a healthy weight?

People might become overweight for lots of reasons – eating too much, or too much unhealthy food, not getting enough physical activity, or a combination of these. Our genes and environment also play a role.

Some people are or become underweight; among other reasons, this may be due to physical or other illness and stress.

Learn more about these reasons and the important concept of energy balance in this section.
