More About Obesity
The terms "overweight" and "obesity" refer to a person's overall body weight and whether it's too high. Overweight is having extra body weight from muscle, bone, fat, and/or water. Obesity is having a high amount of extra body fat.
The most useful measure of overweight and obesity is body mass index (BMI). BMI is based on height and weight and is used for adults, children, and teens.
Millions of Americans and people worldwide are overweight or obese. Being overweight or obese puts you at risk for many diseases and conditions. The more body fat that you have and the more you weigh, the more likely you are to develop:
- coronary heart disease (also called coronary artery disease)
- high blood pressure
- type 2 diabetes
- breathing problems
- certain cancers
Your weight is the result of many factors. These factors include environment, family history and genetics, metabolism (the way your body changes food and oxygen into energy), behavior or habits, and more. You can't change some factors, such as family history. However, you can change other factors, such as your lifestyle habits.
You can take steps to prevent or treat overweight or obesity. Follow a healthy eating plan and keep your calorie needs in mind. Do physical activity regularly and try to limit the amount of time that you're inactive.
Weight-loss medicines and surgery also are options for some people who need to lose weight if lifestyle changes aren't enough.
