Everyone, no matter their age, should strive to keep their BMI in the healthy range. A BMI of between 25 and 29.9 generally indicates that a person is overweight, and a BMI over 30 indicates obesity. It is also possible for a person to be underweight when their BMI is below 18.5. However, it is worth noting that the standards for BMI vary by gender and other factors, and BMI does not account for body frame size or athleticism.
People with a high BMI are considered overweight and should be concerned with things like high blood pressure, diabetes and high cholesterol. According to the CDC, weight loss of only 10 percent of the body weight can lower the risks of these and other diseases.Learn more about Fitness & Exercise
