BMI Calculator BMI (Body Mass Index)

is a measurement of body fat based on height and weight that applies to both men and women between the ages of 18 and 65 years. BMI can be used to indicate if you are overweight, obese, underweight or normal. A healthy BMI score is between 20 and 25. A score below 20 indicates that you may be underweight; a value above 25 indicates that you may be overweight. You can calculate your BMI by using our BMI Calculator below. Please remember, however, that this is only one of many possible ways to assess your weight. If you have any concerns about your weight, please discuss them with your physician, who is in a position, unlike this BMI calculator, to address your specific individual situation.

Underweight Information

BMI is equal to or less than 18.5 (Underweight)
A lean BMI can indicate that your weight maybe too low. You should consult your physician to determine if you should gain weight, as low body mass can decrease your body's immune system, which could lead to illness such as disappearance of periods (women), bone loss, malnutrition and other conditions. The lower your BMI the greater these risks become.

Underweight Treatment

The best way to add weight is to increase your intake of complex carbohydrates, particularly whole grain ones. Foods like whole wheat bread, muffins, pasta, crackers, and bagels are good to include. Also, legumes and fruits would be wise choices.
In order to gain weight, you will have to eat more calories. You will need to include regular exercise and strength training into your lifestyle in order to prevent gaining too much weight as fat. And, as I mentioned, those extra calories should come mainly from additional carbohydrate.
To start, set up a realistic goal weight for yourself. You may need to resign yourself to a less than (what you may consider) an ideal weight. Make good nutrition your priority, and weight gain the second.
It is best to gain weight slowly and steadily. This will help to ensure that your weight gain is in the form of lean body mass and not excessive fat. Don't try to gain more than 1/2 pound a week.

Normal Weight Information

BMI is between 18.5 and 24.9 (Normal Weight)
People whose BMI is within 18.5 to 24.9 possess the ideal amount of body weight, associated with living longest, the lowest incidence of serious illness, as well as being perceived as more physically attractive than people with BMI in higher or lower ranges.

Overweight Information

BMI is between 25 and 29.9 (Overweight)
People falling in this BMI range are considered overweight and would benefit from finding healthy ways to lower their weight, such as diet and exercise. Individuals who fall in this range are at increased risk for a variety of illnesses. If your BMI is 27-29.99 your risk of health problems becomes higher. In a recent study an increased rate of blood pressure, diabetes and heart disease was recorded at 27.3 for women and 27.8 for men. It may be a good idea to check your Waist Circumference and compare it with the recommended limits.

Overweight Treatment

Your body weight is controlled by the number of calories you eat and the number of calories you use each day. So, if you consume fewer calories than you burn, you will lose weight. You can do this by becoming more physically active or by eating less.
You didn't put on extra weight overnight so it is equally unrealistic to take it off quickly. Record a goal that you can reach in one month that is 4 to 8 pounds less than you weigh now. Set a goal you know you can achieve.
Here are some very simple changes that you can start today that will greatly improve your chances of weight loss success:

Eliminate Red Meat

If foods like burgers are basic to your current diet, cutting out red meat can go a long way in helping you make healthier meal choices. Build your meals around fish or poultry.

Cut out fried foods

Grill, bake, roast, broil or boil your food. This also means doing without French Fries and snack foods like Potato Strings, Chips,...

Start with a soup or a salad

By starting dinner with a soup or salad, you will curb your hunger, which will in turn help you keep portion sizes in check and prevent you from overeating.

Stop Cola consumption

For every 20 ounces of Coca-Cola you drink, you're consuming 250 calories. If you're trying to consume around 1500 calories a day in order to lose weight, you can blow your entire calorie budget on soda!

Drink water

Reach for the goal of eight glasses a day. Even if you don't drink eight, you're drinking more than usual.

Obesity Class 1 Information

BMI is between 30-34.99 (Obese Class 1)
Individuals with a BMI of 30-34.99 are in a physically unhealthy condition, which puts them at risk for serious illnesses such as heart disease, diabetes, high blood pressure, gall bladder disease, and some cancers. This holds especially true if you have a larger than recommended Waist Size. These people would benefit greatly by modifying their lifestyle. Ideally, see your doctor and consider reducing your weight by 5-10 percent. Such a weight reduction will result in considerable health improvements.

Obesity Treatment

The method of treatment depends on your level of obesity, overall health condition, and motivation to lose weight.
Treatment includes a combination of diet, exercise, behavior modification, and sometimes weight loss drugs. In some cases of severe obesity, gastrointestinal surgery may be recommended.
