This is the first of 3 methods in the series on "The Ideal Weight for Women – How to Get the Right Figure".
This method uses your BMI Ideal Weight to get a somewhat realistic estimate for how much weight you need to lose to be at your ideal weight.
First you need to know if you have a small, medium, or large body frame (click on the link to see the full method).
OK, now you know your body frame size, you need to know what your current BMI is:
BMI (formula in metric units) = Weight(kg) / (Height(m) x Height(m))
BMI (formula in lbs & ins) = Weight (lbs) x 703 / (Height(in) x Height(in))
Your results will fit in one of the below ranges:
Next you need to decide what BMI would be the ideal for your body frame.
If you take the NORMAL range for e.g. A small framed woman for e.g would aim for the lower end of the NORMAL range – so 18.5 — 20 would be ideal. A mid framed woman would look to be between 20 and 21 and larger frame women should go for 21 — 22.9. You get the idea.
And here is the formula to get your ideal weight from your ideal BMI:
Weight(kg) = BMI (ideal) x (Height(m) x Height(m))
Weight (lbs) = [BMI (ideal) x (Height(in) x Height(in))]/703
For a real life e.g. If I am a medium frame woman (I am), 53 kgs and 1.61m tall – with ideal BMI of 20 then this is my calculation:
Weight(kg) = 20 x (1.61 x 1.61) = 51.842 kgs
That's basically it. According to my BMI ideal, the BMI ideal weight I should aim for 51.8kgs or 114lbs. But unfortunately this method doesn't take into account my body composition or frame – which happen to be extremely important.
But fear not, for that – you need to look at the next post about how to "Calculate Your Ideal Weight According to Your % Body Fat".
