IBW

Today most of us are weight conscious . Many people get tensed even if they gain one pound extra . So for all health & weight conscious people I am sahring some formulas which are used by Dieticianas to calculate the Ideal body weight & other related aspects.

IDEAL BODY WEIGHT( I B W ) :

Ideal body weight is that weight which is associated with least mortality. Ideal body is calculated by using various formulas.One of the simplest formula is BROCA’S INDEX.

BROCA’S INDEX :

1) I B W of a man in Kgs :
HEIGHT OF A MAN IN CMS MINUS 100
Therefore I B W of 6 feet tall man will be =182.8-100 = 82.8 Kgs

2) I B W of a woman in kgs :
HEIGHT OF A WOMAN IN CMS MINUS 100 + SUBTRACT 10% FROM IT.
Therefore IBW of 6 feet tall woman will be = 182.8-100 = 82.8 – 8.2 =74.6 Kgs.

REMEMBER:
1) 1 FEET = 12 INCHES
2) 1 INCH = 2.54 CMS.
3) This formula is used only to calulate IBW of individuals above 18.

WAIST TO HIP RATIO ( WHR)

1) WHR for man :
WAIST IN INCHES DIVIDED BY CIRCUMFERENCE OF HIP
WHR greater than 0.95 is harmful.

2) WHR for woman :
WAIST IN INCHES DIVIDED BY CIRCUMFERENCE OF HIP
WHR greater than 0.8 is harmful.

BODY MASS INDEX ( BMI )

BMI IS CALCULATED AS ,
WEIGHT IN KGS OF A PERSON
—————————————————————
SQUARE OF HEIGHT OF THE PERSON IN METRES
Therefore BMI OF 6 Feet man weighing 90 kgs is
= 90 / 1.828 X 1.828 =26.9

REMEMBER :
1) BMI ranging from 20-25 indicates the individual is normal.
2) BMI ranging from 25-27 indicates……………….. over weight
3) BMI ranging from 27-29.9 indicates……………………….obese
4) BMI ranging from 30-40 indicates…………..Grade 2 obesity.
5) BMI above 40……………………………………………Grade 3 obesity
