Obesity is one of the leading causes of death and disability in the United States. But being overweight is not always due to a lack of willpower or exercise. Sometimes your family history may be to blame. For some people, no amount of dieting or exercising alone will help.
The Difference Between Overweight & Obese
People who are overweight or obese have an increased risk of developing health problems, such as diabetes and heart disease. If you have a body mass index (BMI) of 25 to 30, you are considered overweight. If you are overweight, losing even 5 percent of your body weight reduces your risk of developing chronic conditions. If you have a BMI greater than 30, you are considered obese.
What Is Obesity?
Obesity is a condition in which the body stores excess energy in the form of fat. You are considered obese if you weigh 20 percent or more over your ideal body weight or have a body mass index (BMI) of 30 or more. Obesity is also categorized by severity:
Class 1: BMI of 30 to <35
Class 2: BMI of 35 to <40
Class 3: BMI of 40 or higher
Morbid obesity is a condition in which individuals are at least 100 pounds over their ideal weight or have a body mass index (BMI) of 40 or higher. Morbid obesity can result from emotional, biochemical and genetic influences. It is a potentially dangerous condition because it is a risk factor for other medical problems that may lead to disability and early death.
