LET’S GET PHYSICAL
One of the indicators of healthy physical body is the body mass index (BMI), which is the ratio of weight to the height. Although BMI doesn’t measure the body fat, it is useful in estimating the ideal body weight based on the height of the person.
The body mass index is computed by the person’s body weight in kilogram divided by the square of his height in meter. It usually diagnoses weight problem.
For example, a 5’2 person weighs 106 lbs. To get the height in meters, multiply 5.2 (height in feet) by 12 and multiply again by 0.0254. (Answer: 1.58 meters) For the weight, divide 106 lbs by 2.2 to get the weight in meter (Answer: 48.18 kgs). Then, divide 48.18 by the square of 1.58 (which is 2.4964). His BMI is 19.2997. Ideal BMI is 18.5 to 24.9, which means if your BMI falls within that bracket, your weight is normal.
Another measuring instrument that is widely used is the waist to hip ratio (WHR), the ratio of the circumference of the waist (usually located right above the hip bone) and hip (the widest part). It shows what body type you have: are you a pear-shaped or an apple-shaped?
For the waist circumference, the target measurement is 31 inches for women and 35 inches for men.An indicator of health risks, WHR is computed by dividing the waist circumference by the hip circumference. For example, the waist measures 26 inches, while the hip is 34. If you divide 26 by 34, the answer will be 0.7647. Ideal WHR is less than 1 for men and less than 0.85 for women.
Physical activity such a walking and running can do a lot, but it should hand in hand with good nutrition. – Ma. Glaiza Lee
