Body Mass Index Bmi Are You At A Healthy Weight

The body mass index,​ or​ BMI,​ helps clarify an​ important distinction between being overweight or​ being obese. if​ you weigh too much,​ you're obviously overweight. But if​ you have a​ very high proportion of​ body fat,​ you're obese. Based on​ your body mass index,​ your doctor or​ other health professional will classify your weight as​ healthy,​ overweight,​ or​ obese.

According to​ the​ National Heart,​ Lung and Blood Institute (NHLBI),​ the​ BMI "describes body weight relative to​ height and is​ correlated with total body fat content in​ most adults". in​ almost all cases,​ this means that the​ BMI will accurately reflect your weight and proportion of​ body fat as​ a​ function of​ your height and weight when categorizing you as​ healthy,​ overweight or​ obese.

Calculating your approximate body mass index is​ relatively straightforward,​ although you'll probably need a​ calculator just to​ save time. to​ get your BMI,​ multiply your weight in​ pounds by 703. Next,​ divide that result by your height in​ inches. Then divide that result by your height in​ inches one more time.

As an​ example,​ let's say you weigh 180 pounds and are 5 feet 10 inches tall.

Multiply 180 by 703 to​ get 126,​540. Next,​ divide this by 70 (70 inches is​ the​ same as​ 5' 10") to​ get 1807.7. Now,​ divide 1807.7 by 70 one more time. the​ result -- 25.8-- is​ your approximate BMI or​ body mass index. if​ you don't have a​ calculator handy,​ you can get the​ same result using the​ free interactive BMI calculator at​

If the​ above example sounds you,​ you might be surprised to​ learn that you're ever so slightly heavier than your doctor might like. a​ BMI from 18.5 up to​ 25 is​ considered healthy,​ from 25 up to​ 30 is​ classified as​ overweight,​ and 30 or​ higher is​ obese.

Generally,​ says the​ NHLBI,​ the​ higher a​ person's BMI,​ the​ greater the​ risk for health problems. in​ addition to​ causing your BMI to​ skyrocket,​ excess body fat is​ a​ well recognized health risk. Men and women with waist lines in​ excess of​ 40 and 35 inches,​ respectively,​ are much more at​ risk for health problems like Type 2 diabetes,​ high blood pressure and high cholesterol.

Like every rule of​ thumb,​ this one also has it​ exception. Body builders,​ for example,​ often have a​ body mass index above 25 and sometimes even above 30. in​ this case,​ however,​ the​ higher BMI reflects the​ fact that body builders have more muscle mass without having more fat.

Finally,​ there's still only one sure way to​ lower your BMI if​ you're overweight or​ obese: Eat less and exercise more. Your body will burn more calories than you eat and your body mass index will go down over time.
