Relative Fat Mass (RFM) Calculator

Relative Fat Mass Calculator

• The Relative Fat Mass Calculator helps you to find the Relative Fat Mass (RFM) value of your body to stay healthy.
• Relative Fat Mass Calculator predicts body fat mass using only two body measurements - height and waist circumference. 
• RFM Calculator estimation is more accurate than the well-known body mass index (BMI), which often misclassifies obesity.
• Relative fat mass (RFM) as a new estimator of whole-body fat percentage ─ A cross-sectional study in American adult individuals by Orison O. Woolcott & Richard N. Bergman.

 

Steps To Calculate Relative Fat Mass

1. Select Your Gender
2. Enter Your Waist (cm) & Height (ft)
3. Check the Result of RFM Relative Fat Mass

 

Relative Fat Mass Formula

 

Here is a formula for Relative Fat Mass For All.

 

Relative Fat Mass For Adult Males	RFM =  64 – 20 x (Height / Waist circumference)
Relative Fat Mass For Adult Females	RFM = 76 – 20 x (Height / Waist circumference)

 

Where:

• Height in meters
• Waist circumference in meters

 

Is RFM better than BMI Calculator?

The latest study and research show that Relative Fat Mass (RFM) is more precise than Body Mass Index (BMI).

 

Relative Fat Mass Normal Range

 

BFP Category	Females (%Fat)	Males (%Fat)
Essential Fat	10-13%	2-5%
Athletes	14-20%	6-13%
Fitness	21-24%	14-17%
Average	25-31%	18-24%
Obese	32% & higher	25% & higher

 

 

Guide For Measuring Waist Circumference

1. Wear little cloth as possible.
2. Stand straight with your feet close together.
3. Keep your arms down at the sides.
4. Take the measurement after the end of a normal expiration.
5. For Males: Measure the circumference of the waist across the belly button. Repeat the measurements twice and take the average.
   For Females: Measure the smallest circumference of the waist, (The smallest circumference is usually halfway between the lower point of the sternum and the belly button) roughly one inch above the belly button. Repeat the measurements a few times and take the smallest value.

 

Calculate Relative Fat Mass

• The Relative Fat Mass (RFM) index estimates body fat percentage based on every person’s ratio of height and waist measurements. 
• This relative fat mass index is considered a simple anthropometric procedure, easier to estimate than other body fat percentage methods, and more accurate than the body mass index (BMI).
• RFM has been generally validated research established gender-specific cut-off points for obesity.

 

Common Formula

The above individual formulas for men and women can be combined like this.

RFM = 64 − (20 × (Height ÷ Waist) ) + (12 × Sex)

 

Healthy Range Body Fat Percentage for Men and Women

Here are the exact healthy range body fat Percentage Distributions for Men and Women using the DXA scan. 

 

Health Range	Women	Men
Essential Fat	16.1-18.8%	6.8-9.4%
Athletic	19.7-25%	10.3-16.5%
Fit	25.9-28.6%	17.4-20.0%
Acceptable	29.4-34.8%	20.9-26.1%
Obese	35.7%+	27.0%+

 

• Body fat percentage distribution and the distribution of fat itself differs for adult men and women. 
• Starting around puberty, men and women will start to show different fat distribution patterns.
• Since caliper and DXA estimates of body fat differ, we need to use two scales to present health breakpoints with body fat percentages. 
• RFM body fat percentage health status scale comes from ACE, the American Council on Exercise.
• Anything in 'Acceptable' weight roughly maps to 'Overweight' in the BMI Calculator presented scale. 
• 'Essential Fat' is 'Underweight' and can be quite hazardous. 
• Men and women will likely encounter massive drive to eat food, and women of childbearing age might lose their menstrual cycle.
• Please consult a medical professional for any advice, especially if these estimates put you on the extremes of the scale.

 

Tips For Healthy Relative Fat Mass

• To keep your body fat ratio at a healthy level and free from diabetes and heart disease, you must take good care of yourself. 
• This means practicing the time-tested combination of good nutrition and regular exercise. 
• Of course, you should always consult with your healthcare provider before undertaking any diet or exercise program.

 

Diet

• Maintain a regular diet of fresh vegetables and fruits
• Choose whole grains and lean sources of protein
• Drink water over sugary beverages
• Eliminate or limit processed foods including snacks such as chips, cookies & candy
• Keep an eye on your portion size

 

Daily Exercise

• Choose movement when possible throughout the day; for example, take the stairs instead of an elevator when given the choice
• Consider a short walk daily
• Ride your bike or stationary bike
• Work in your yard
• Take a swim
• Lift weights

 

Relative Fat Mass RFM vs BMI

• Relative Fat Mass (RFM) identified a simpler and more accurate way of measuring body fat than BMI: the RFM. 
• RFM showed better accuracy than BMI and had fewer false negative cases of body fat-defined obesity among women and men. 
• As you can probably guess, the RFM is quite a bit different from the BMI. 
• The BMI formula uses both your height and your weight to calculate your number, which in turn is used to determine whether you’re underweight, overweight, obese, or have a normal weight. 
• It’s not exactly a secret that many experts consider the BMI to be an inaccurate measure of body fat; after all, a BMI cannot distinguish between body fat, bone mass, and muscle. 
• Heck, by the BMI standards, a lot of bodybuilders might be considered “overweight” or even “obese.” 
• The RFM, on the other hand, only uses your height and weight circumference measurements — but it still does a better job than the BMI at calculating your body fat percentage, experts say. 
• In the study, researchers looked at more than 300 potential formulas for estimating body fat using a large database of 12,000 adults. 
• Then, they calculated the RFM for 3,500 patients and compared the results to the participants’ outcomes from a high-tech body scan known for accurately measuring body fat, along with tissue, bone, and muscle. 
• Of all the formulas used, the RFM results were the closest to the precise measurements offered from the body scan.
• RFM is a new index for measuring body fatness that can be easily accessible to health practitioners trying to treat overweight patients who often face serious health consequences like diabetes, high blood pressure, and heart disease.

 

Summary

Overall Relative fat mass Calculator estimation is more accurate than the well-known body mass index (BMI), which often misclassifies obesity. Check More Medical Health Related Calcultor on Drlogy Calculator to get exact health solution.
