How to find your ideal weight!How to find your ideal weight!

My BMI says I am at the low end of normal weight, but I know I need to gain weight in order to have healthy levels of body fat. When I was at a healthy level of body fat (%15 or so), I was already in the middle of the scale for a normal weight. Even when I was "overweight" according to BMI, I had an acceptable level of fat. You just really have to know your own body, I guess. Everyone's different."

Think about how tough it is to create something that can take ONLY someones weight/height and then classify their health...Of course there are going to be "normal" fat out of shape people, and "overweight" and even "obese" perfectly healthy ripped people. But for how little information it works with, give it credit where credit is do. Nothing is perfect."

BMI, or body mass index, is a simple and widely used method for estimating body fat. BMI was developed by the Belgian statistician and anthropometrist Adolphe Quetelet. It is calculated by dividing the subject's weight by the square of his/her height, typically expressed either in metric or US "Customary" units. You can use BMI to estimating your ideal weight:

Metric: BMI = kg / m2
Where kg is the subject's weight in kilograms and m is the subject's height in metres.
US/Customary: BMI = lb * 703 / in2
Where lb is the subject's weight in pounds and in is the subject's height in inches.
The current definitions commonly in use establish the following values, agreed in 1997 and published in 2000:
* A BMI less than 18.5 is underweight
* A BMI of 18.5–24.9 is normal weight
* A BMI of 25.0–29.9 is overweight
* A BMI of 30.0–39.9 is obese
* A BMI of 40.0 or higher is severely (or morbidly) obese
* A BMI of 35.0 or higher in the presence of at least one other significant comorbidity is also classified by some bodies as morbid obesity.

In a clinical setting, physicians take into account race, ethnicity, lean mass (muscularity), age, sex, and other factors which can affect the interpretation of BMI. BMI overestimates body fat in persons who are very muscular, and it can underestimate body fat in persons who have lost body mass (e.g. many elderly). Mild obesity as defined by BMI alone is not a cardiac risk factor, and hence BMI cannot be used as a sole clinical and epidemiological predictor of cardiovascular health."
