Body Fat Measurement Comparing Percentage with Body Mass - Fat Loss Laser

Weight, Body Fat, Body Mass Index - What do all these numbers mean? And what do they really say about your health?

Some experts tagged BMI, or body mass index, as the most accurate way to determine the weight effect on your health. In fact, the most recent medical research uses BMI as an indicator of the health status and disease risk of someone.

The CDC provides the following intervals for BMI values ​​for adults:

Below weight less than 18.5 Recommended 18.6 to 24.9oweight 25.0 to 29.9Ebese 30 or greater

but others feel that body percentage-fat is really the way to go.

"BMI numbers are very general to be really helpful," says Tammy Callahan, Measurement Life Marketing Manager, which manufactures a fat analyzer for use in gyms and medical settings. "These numbers have been developed using data from a huge number of people. They say nothing about their own body composition, how much of their weight is fat and how much is muscles and tissues."

but do not throw away this IMC chart yet.

High Reps Vs Low Reps For Fat Loss - Body Fat Measurement Comparing Percentage with Body Mass

High Reps Vs Low Reps For Fat Loss
Are you at risk? "I am not against people who use devices to discover fat percentages, but it is a well-established fact that your IMC number tells you a lot about the risk of diseases, especially heart disease and diabetes" Says Harry Duval, PhD, associate professor of science for the exercise of the University of Georgia in Athens. "Fat percentages simply have enough research behind them yet to tell you how much risk of diseases you face."

You are probably familiar with the body mass index. BMI is an equation that gives you a numerical classification of your health based on height and weight. As your BMI rises, the same risk of developing weight-related diseases such as heart disease and diabetes. (To discover your BMI, use our calculator.)

But even the more and more people are using their IMC number as a general health indicator, the research on the percentage of fat is improving.

in September 2000, the American Journal of Clinical Nutrition published a study showing that the percentage of body fat can be a better measure of your risk of weight-related diseases than BMI. Steven Heatsfield, MD, Director of the Research Center Obesity at the Roosevelt Hospital of St. Luke, New York, and his colleagues rated more than 1,600 people from various ethnic origins. The researchers took body fat measurements and studied as their body fat related to the risk of disease.

"Many studies have BMI related to the risk of disease," Heymsfield noted. "What we did was correlate the percentage of body fat for BMI, allowing us to take the first step to link the body percentage to the risk of disease. This new survey reveals the value of evaluating body fat more directly using the latest technology Scientific to measure body-fat percentage, "he added.

Although several research studies have indicated that a high BMI is associated with heart disease, stroke, type 2 diabetes and some cancers, BMI does not distinguish muscle fat.

"If we think of BMI being an approximate measure of body fat, there are people - especially some highly trained athletes - who are overweight but not too," says Heymsfield. "Likewise, there are people who are of a normal weight according to BMI scales, but that are excessively. BMI is a broad and general measure of risk. Body evaluation is much more specific for your real content of fat and thus provides an image. "

Body Fat Measurement Comparing Percentage With Body Mass

How much fat is ok? The American Exercise Council provides the following tracks for the percentage of body fat:



Essential Fat













32% more

26% more


"What we want people to shoot is a range instead of a magical number," says Barbara J. Moore, PhD, president of form! America. "It's comforting to know that women can be and should be more fat than men. They have a totally different playback function and the biggest fat in women supports this reproductive function."

But not all fat percent measurements are the same. Some methods have high error rates. The two most common methods used are measurement of skin deployment and bioelectric impedner analysis

In the measurement of the skin fold, a trained specialist uses tweezers to measure specific spots on the body. These measurements are compared to a graph that estimates the percentage of fat. You may have seen this used in your physician's academy or office. These skin bending devices can also be purchased and used at home. However, the accuracy of this method varies greatly based on user skills. Bioelectric impedance analysis, the other common method, is the technology behind many percentage scales of fat sold for domestic use.

"Error rates for these can be as high as 8%, more or less," says Duval. "Other methods are highly accurate, but much more complicated, such as X-ray analysis, water displacement and others. That's why IMC has its place in weight management. It can be raw, but it gives you a good Risk idea quickly and easily. "

Duval says the percentage measurement of fat, despite inaccuracies, can be useful.

"In terms of ease of use and utility, BMI can not be beaten," he says. "But if a home, fat measuring device helps someone remain focused on your diet and level exercise and motivated to stay healthy, so I think the device has a place in weight management."
