Good Question: Why should I know my Body Mass Index?
Folks in Lexington were just placed in a not so good category..
Men's Health Magazine says Lexington is among the most sedentary cities in the country.
While many disagree with that label, they do agree being active is key to maintaining your health.
Knowing your numbers, like weight, cholesterol, blood pressure can all be helpful, but what about BMI.
"BMI is body mass index and it's a tool used to measure weight in adults," said Bridget Adams, a nurse practitioner with the Little Clinic.
Adams uses a graph to help determine a person's BMI.
By using a chart that plots your height in inches and your weight you will find your body mass index.
"There are four categories underweight, normal weight, overweight and obese," said Adams.
Underweight-18.5 or lower
Normal Weight: 18.5-24.9
Overweight-25 to 29.9
Obese-30 or greater
The higher the number the more risk.
"That can put you at more risk for cardiovascular disease, diabetes, pre-mature death, arthritis a number of diseases," said Adams.
To lower your BMI, Adams says it has to be a change in lifestyle by getting more exercise and improving your diet.
The CDC $150 billion is spent each year on obesity related diseases.
You can stop by any Little Clinic location in Lexington to have your BMI checked.
