How to Lose Your Visceral Fat (The Dangerous Fat) Faster - Dr. Mandell

Subcutaneous fat and body composition -

New clients walk into our classes on a daily basis hoping that exercise will be the panacea. Yet, efforts such as these to achieve thinness are often based on popular misconceptions about body weight and body composition. Being thin does not necessarily reduce one's health risk. In fact, obsession with becoming thin often leads to serious eating disorders such as anorexia and bulimia.

Thinness simply refers to weighing less than the recommended values in age-height-weight tables. Leanness, on the other hand, refers to the muscle, bone, and fat composition of your body weight. Although some lean individuals may actually weigh more than their "tabled" ideal body weight, low body fat lessens the risk of health problems.

Understanding and being able to explain the difference between healthy leanness and undesirable thinness is one important concept the fitness instructor, personal trainer, and exercise leader must share with clients. In addition, there are some other reasons to become more informed about body composition: o To develop complete physical fitness profiles for clients.

o To monitor body fat loss and muscle growth resulting from exercise. o To provide baseline data for nutritional counseling and treatment of obesity. o To describe changes due to growth, development, maturation, and aging. o To maximize the performance of athletes.

Article Pag e. Getting a Grip on Body Composition By Len Kravitz, Ph. and Vivian H. Heyward, Ph. Body Composition The body is composed of water, protein, minerals, and fat. A two-component model of body composition divides the body into a fat component and fat-free component.

Body fat is the most variable constituent of the body. The total amount of body fat consists of essential fat and storage fat. Fat in the marrow of bones, in the heart, lungs, liver, spleen, kidneys, intestines, muscles, and lipid-rich tissues throughout the central nervous system is called essential fat, whereas fat that accumulates in adipose tissue is called storage fat.

Essential fat is necessary for normal bodily functioning. The essential fat of women is higher than that of men because it includes sex-characteristic fat related to child-bearing. Storage fat is located around internal organs internal storage fat and directly beneath the skin subcutaneous storage fat.

It provides bodily protection and serves as an insulator to conserve body heat. The relationship between subcutaneous fat and internal fat may not be the same for all individuals and may fluctuate during the life cycle.

Lean body mass represents the weight of your muscles, bones, ligaments, tendons, and internal organs. Lean body mass differs from fat-free mass. Since there is some essential fat in the marrow of your bones and internal organs, the lean body mass includes a small percentage of essential fat.

However, with the two-component model of body composition, these sources of essential fat are estimated and subtracted from total body weight to obtain the fat-free mass. Practical methods of assessing body composition such as skinfolds, bioelectrical impedance analysis BIA , and hydrostatic weighing are based on the two-component fat and fat-free mass model of body composition.

Standards of Body Fatnessary Our bodies require essential fat because it serves as an important metabolic fuel for energy production and other normal bodily functions. Body fat percentages for optimal fitness and for athletes tend to be lower than optimal health values because excess fat may hinder physical performance and activity.

When prescribing ideal body fat for a client, you should use a range of values rather than a single value to account for individual differences.

As a result of these changes, men and women who weigh the same at age 60 as they did at age 20 may actually have double the amount of body fat unless they have been physically active throughout their life Wilmore et al.

Table 1. Body Composition: A round table. The Physician and Sportsmedicine, 14 3 , Assessing Body Composition The search for valid methods of measuring body composition that are practical and inexpensive is an ongoing process for exercise scientists and nutritionists.

Standard age-height-weight tables derived from life insurance data often incorrectly indicate individuals to be overweight. Some practical methods of measuring body composition include skinfolds, circumference girth measures, hydrostatic weighing, bioelectrical impedance, and near-infrared interactance.

Other advanced methods discussed in research journals include isotope dilution, neutron activation analysis, magnetic resonance imaging, and dual-energy x-ray absorptiometry. This error factor may be increased dramatically due to the skill or lack of it of the technician taking the measurements.

The following sections will focus on three body fat measurement techniques that are often accessible to fitness professionals: hydrostatic weighing, bioelectrical impedance, and skinfolds. Hydrostatic Weighing Hydrostatic weighing is a valid, reliable and widely used technique for assessing body composition.

It has been labeled the "Gold Standard" or criterion measure of body composition analysis. It is based on Archimedes' principle. This principle states that an object immersed in a fluid loses an amount of weight equivalent to the weight of the fluid which is displaced by the object's volume.

This principle is applied to estimate the body volume and body density of individuals. Since fat has a lower density than muscle or bone, fatter individuals will have a lower total body density than leaner individuals.

As the person is being submerged, the air in the lungs must be exhaled completely. The air remaining in the small pockets of the lungs following a maximal expiration is referred to as the residual lung volume.

The residual lung volume may be determined using a number of laboratory techniques or it is often estimated using age, height, and gender-specific equations. Once your body weight, the underwater weight, and the residual lung volume are known, total body density may be calculated.

From the total body density, the percent body fat can be estimated using the appropriate age-gender equation. One limitation of hydrostatic weighing is that it is based on the two- component model fat and fat-free mass which assumes when calculating total body density that the relative amounts and densities of bone, muscle, and water comprising the fat-free mass are essentially the same for all individuals, regardless of age, gender, race or fitness level.

It is now known that this is not the case. For instance, the fat-free body density of young Black men is greater than that of white men. Because of this, the lean body mass is overestimated and the body fat is underestimated for many Blacks.

Also, after age 45 to 50, substantial changes in bone density, especially in women, invalidate the use of an assumed constant value for fat-free body density when converting total body density to percentage of body fat. This is why age and gender specific equations need to be used for estimating body fat.

As researchers learn more about age-related changes in bone mineral, hydrostatic weighing will eventually provide a more accurate prediction of body fat for older men and women. Bioelectrical impedance analysis BIA is based on the fact that the body contains intracellular and extracellular fluids capable of electrical conduction.

A non-detectable, safe, low-level current flows through these intracellular and extracellular fluids. Since your fat-free body weight contains much of your body's water and electrolytes, it is a better conductor of the electrical current than the fat, which contains very little water.

So this technique is essentially an index of total body water, from which fat-free mass is estimated. The popularity of the BIA method has grown significantly over the last few years because it is painless, quick, and easy to administer the test.

To take the test, you lie on a testing table or floor and electrodes are attached to your hands and feet. You do not feel a thing as the current passes through your body.

Average time for administering this test is about 10 minutes. No eating or drinking within 4 hours of the test 2. No exercise within 12 hours of the test 3. Urinate within 30 minutes of the test 4. No alcohol consumption within 48 hours of the test 5.

There is a tendency for BIA to overestimate percent body fat in very lean clients and underestimate body fat in obese clients. All in all, if the guidelines for testing are followed, the BIA method is a satisfactory method for assessing body composition of most people.
