(a) The most commonly used formulae for you to know whether you are underweight within the health range or overweight is known as Body mass index (BMI). This is how it is calculated.
(a) Measure your height in inches.
(b) Square that height in inches for example if your height in inches is 82 inches
Multiply 82 x 82 =
(c) Measure your weight in pounds. Let us take it to be 120 pounds.
Body Mass Index = 82 x 82 x 703
120 x120I know you have not forgotten how to use mathematical constants. 703 is constant.
After calculating your BMI, the following guidelines will be very important.
(a.) A BMI of less than 18 means you are underweight.
(b.) A BMI of less than 18.5 indicates you are thin for your weight.
(c.) A BMI between 18.6 and 24.9 indicates you are at healthy weight.
(d.) A BMI of between 25 and 29.9 suggests you are overweight for your height.
(e.) A BMI of 30 or greater indicates obesity. If you are obese try consulting for ways on how to loss weight. I suggest you try the following:
(a.) Choose the best program to loose weight do you want an Q-book that will help you with information and tips of loosing weight using raw food. You may also decide to a product that is healthy in the market and known to help many loose weight.
Okay that having been said it is important to know that BMI is not health science. This formulae has limitations and weaknesses. BMI does not take into account muscle or your overall body type. BMI should be used as a guideline. BMI does not take into account your body fat percentage.
The history of this formula
Credit is given to Ancel keys for making this formula popular in a 1972 paper. However he explained that BMI was appropriate for population studies not individual diagnosis. This is the guideline used in every weight loose program and it is important that it is clearly understood. Don’t forget BMI is a relationship between height and weight.
(b) Waist to hip ratio
Recent no search has found that the waist to hip ratio provides a much better indicates than BMI of whether an individual has too much body fat. If you decide to you this formula that following guidelines should help.
(1) Generally the waist hip ratio should not proceed about 0.9 for men and 0.8 for women.
The importance of this formula is that it takes into account the accumulation of fat which the dangers the following assumption has to be made the person in discussion does not loose any muscle. Anyway formula must have there assumption just to us at least have some guidelines. Then the ideal weight will be:
Ideal Weight = Lean Body Mass = 156 = 15% /1-15% = 184 1 - Desired fat percentage =1 – 15
How do you calculate your body fat percentage?
Your body fat percentage is the percentage of fat your body contains. If your weight 200 pounds and 10% fat it means that your body consists of 20 pounds fat and 180 pound lean body mass (bone muscle, organ tissue blood.). The body fat formula should be used in the morning.
(a) Body fat formula for women.
(1) Factor 1
(Total body weight x 0.732) + 8.987
(2) Factor 2
Wrist measurement (at fullest point) / 3.140
(3) Factor 3
Waist measurement (at naval) x 0.157
(4) Factor 4
Hip measurement (at fullest point) x 0.249
Culprit in weight increase.
(c) Ideal body weight formula
Many experts in Health and Fitness having understood the limitations of Body Mass Index have to come up with formula that takes into account body fat. One such formula is the one formatted by Marc Perry of Buitlean. Com. This is the formula.
Lean Body Mass1 - Desired Body Fat percentage
What is lean Body Mass (LBM)
This is your fat mass; that every thing in your body that’s not fat: your bones, blood, muscle and organs.
How do you arrive at your lean Body Mass?
Lean Body Mass = Your Body Weight x Your constant body fat percentage
An example will do at this point. If a person has a weight of 200 pounds and 22% body fat how do you arrive at his LBM:
200 x 22% = 200 x 22/100 = 44
Thus 200 – 44 = 156 pounds
To arrive at the ideal weight will depend on what that person desires. What if the above person desires an ideal body fat of 15% what will be his ideal weight.
Note: When calculating this person’s ideal weight
Lean Body Mass = Factor 1+Factor 2 – Factor 3 - Factor 4 + Factor 5
Body Fat Weight = Total body weight - Lean Body Mass
Body Fat Percentage = Body Fat Weight x 100
Total body weight
Body Fat Formula for Men
1) Factor 1
(Total body weight x 1.082)+ 94.42
2) Factor 2
Waist measurement x 4.15
Lean Body Mass
Factor 1- Factor 2
Body Fat Weight = Total body weight - Loan body mass
Body Fat percentage = Body fat weight x 100 Total body weight
