Body composition and body weight

Body composition describes the Body composition and body weight of fat and non-fat mass in your Natural remedies for sore throat. and Weighh, R. Minus Related Compsition. Several techniques described in the literature are more accurate than the techniques described above, but the expense of purchasing costly equipment or the time required to perform the measurements may not make their use feasible by the military services.

Body composition and body weight -

It is a tool for indicating weight status in adults and general health in large populations. BMI correlates mildly with body fat but when used in conjunction with a body fat measurement gives a very accurate presentation of your current weight status.

With that being said, an elevated BMI above 30 significantly increases your risk of developing long-term and disabling conditions such as hypertension, diabetes mellitus, gallstones, stroke, osteoarthritis, and some forms of cancer. For adults over 20 years old, BMI typically falls into one of the above categories see table above.

DXA body composition analysis Dual X-ray Absorptiometry DXA is a quick and pain free scan that can tell you a lot about your body. Composition analysis available. Example analysis from a DXA scan PDF Fat: function, metabolism and storage Although body fat endures a negative reputation, fats and lipids play critical roles in the overall functioning of the body, such as in digestion and energy metabolism.

Since muscle contains more water than fat, the device is able to differentiate between the tissue and estimate how much of each you have. Dual-energy X-ray absorptiometry DXA : This is a scan that uses low-dose X-rays to measure the density of different tissues in your body.

It can provide accurate, reliable, and detailed information about your bone mineral density, muscle mass, and fat mass.

However, it is also expensive and requires specialized equipment and trained personnel; often in a hospital or clinic. Some tips for improving your body composition are: Eat a variety of foods that provide adequate protein, carbohydrates, and fats.

Protein is especially important for building and maintaining muscle mass. General recommendations are 0. However, if you are doing a lot of exercise then recommendations may be higher; work with a dietitian for personalized targets.

Limit processed foods that are high in sugar, salt, and trans fats. These foods can increase inflammation and contribute to weight gain and chronic diseases. Instead prioritize whole food snacks like fresh fruits, nuts, or unsweetened yogurt.

Do resistance training at least two to three times per week to build muscle strength and endurance. Resistance training involves lifting weights or using your own body weight to create resistance against gravity.

Do aerobic exercises like brisk walking, jogging, dancing, or playing sports. Choose an activity that you enjoy and can do consistently, aiming for at least minutes of moderate-intensity activity per week. Aerobic exercise can help you burn fat, improve your endurance, lower your blood pressure, and improve your mental health.

According to this hypothesis, when individuals attempt to lose weight below a set level, body defense mechanisms come into play that limit the amount of weight lost unless there are major changes in lifestyle, eating, and exercise Keesey, ; Keys et al.

Studies in humans have shown that there is frequently minimal or no relationship between food intake and body fatness for individual people Thomas et al. Because a number of recent articles have reviewed methods for assessing human body composition Buskirk, ; Heymsfield and Waki, ; Lukaski, ; Smalley et al.

This section will begin with a brief review of the operational definitions used in this report, followed by an overview of methods for assessing body composition as directly applied to the military services. Body composition, in the context of these proceedings, refers to the relative proportion of lean body mass LBM and body fat mass BFM within the body.

LBM can further be subdivided into muscle mass, body water, and bone mass. These two approaches are commonly referred to as a two-compartment model LBM and BFM or a four-compartment model BFM, muscle mass, body water and bone mass for assessing body composition. Because the main concern of the military is LBM and BFM as related to performance, the two-compartment model is generally used by the services.

However failure to account for differences in bone density can lead to systematic errors in measurements, so the two-compartment model must be used with caution when applied to an individual.

Fat-free mass FFM refers to the portion of the body remaining after all fatty substances are extracted. For the purposes of this report, FFM will be used interchangeably with LBM.

The most commonly used anthropometric assessments are height, weight, skinfold thicknesses, body diameter, and body circumference measurements.

Numerous previous studies in the literature have used combinations of anthropometric measurements to estimate body fat. It is well recognized that there are problems with this approach.

A major criticism of the use of anthropometric data to calculate body fat is that the formulas are based on population data, and when such formulas are used to calculate body fat of an individual, a significant error may result Lukaski, In other words, the formula may have a small error when predicting body fat for a population but a greater error for predicting body fat for a given individual.

Another problem with anthropometric measures is observer error. Hodgdon Chapter 4 discussed the difficulty of training military personnel to accurately measure skinfolds and body circumferences. After performing trial skinfold measurements, only 24 percent of personnel were proficient.

However, 68 percent of trainees had reached proficiency after only 45 measurements of body circumferences. In cross-validation studies, the standard errors for the formulas used by the different services ranged from 3.

Thus, based alone on errors in measurement and inherent individual differences, these data indicate that it would be possible to inappropriately target an individual for separation or to reject a new recruit.

Due to these concerns, the military should consider the importance of validation of their measurements through multiple observations on each individual.

When measurements of height and weight are combined with measurements of waist and hip circumferences, a better assessment of long-term health risk may be obtained. Increasing evidence suggests that the deposition of fat in the abdominal area, particularly in the intraabdominal depots, is associated with a variety of diseases including hypertension, diabetes mellitus, hyperlipoproteinemias, and increased cardiovascular risk NIH, Using these measurements to screen recruits at accession may help select individuals with lower long-term risk for health problems.

Using them in older military personnel also may identify individuals, with or without obesity, who are at increased health risk, and who should receive special attention for weight or body fat reduction. Densitometry has generally been considered the standard against which all other techniques for measuring body composition are compared.

However, the formulas on which this method is based were calculated originally from carcass analysis of only seven individuals Brozek et al. In this procedure, which assumes the two compartments of LBM and BFM, the density or specific gravity of the body is measured by weighing the body in air and under water, with correction made for residual air in the lungs Behnke et al.

The relative proportion of the two compartments is calculated, with assumptions made about the density of the two compartments.

The density of the body fat is assumed to be constant. Although interstitial muscle fat has a slightly higher density than depot fat, this assumption does not usually lead to a significant error. Much more of a problem is the assumption of a density for LBM, because it can be quite variable depending on age, race, physical activity, gender, and possibly other variables, such as bone mass.

Underwater weighing has also not been well standardized. For example, the influence of age, gender, race, and ethnic group has not been evaluated. The relatively greater lean mass, particularly bone mass, that is present in many Blacks further adds to the inaccuracy of the formulas for this population.

The Committee recognizes that underwater weighing could eventually be improved if the two-compartment model in present use applied densities for lean body mass that are specific for age, gender, and ethnicity.

As with the calculation of body composition from anthropometric data, underwater weighing measurements may have significant error. The technique requires special equipment and highly specialized training, which limit its use to specialized facilities.

Expensive equipment and the time required to train technical staff, coupled with the fairly long time it takes to do a measurement of a single individual, precludes this technique from being useful for accession or retention screening of military personnel.

The principle on which bioelectric impedance analysis BIA is based is that lean tissue conducts electricity better than does fat tissue.

Electrodes are placed on the arms and legs, and a low-level current is run through the individual. Impedance—resistance to the flow of electricity—is measured, and the percent body fat is calculated by a formula Segal et al. This technique has been standardized for several populations, but as with the techniques mentioned above, it is less accurate when used in a given individual.

Some training is required to achieve reasonable reproducibility, and there is significant interobserver variation. Segal et al. It would appear that BIA, particularly with the most modem equipment, is preferable to anthropometry.

However, BIA as commonly used at present, does not give any information on regional fat distribution which may be of military interest and importance. More research is needed to validate this technique. Several techniques described in the literature are more accurate than the techniques described above, but the expense of purchasing costly equipment or the time required to perform the measurements may not make their use feasible by the military services.

These techniques include dual photon absorptiometry, neutron activation, whole body potassium 40 counting, electromagnetic conductance, and body water measurement by radioactive or stable isotopes. Advances in the development of multicompartmental chemical approaches to the determination of body composition in humans have recently been summarized by Heymsfield and Waki Most of these techniques would be of great research interest for validating simple measurements that can be used on a large scale in the military, but they are less practical for routine use.

Of these methods, only dual photon absorptiometry has potential for routine use as a secondary measure of body composition by the military see review in Chapter Like many new techniques additional validation studies are needed.

This equipment also requires a substantial financial investment and specially trained personnel to operate. Many studies have documented an increase in body weight and percent body fat with increasing age, at least over the age range of active duty military personnel Borkan et al.

For the majority of people, LBM decreases with age and body fat increases with age, even if body weight does not change. This fact is recognized by the military's age-adjusted standards for body weight, body fatness, and performance.

Alterations in body composition with age also exacerbate the problem of differences in accession versus retention standards for excess body weight and body fatness. The rationale for the difference between accession and retention standards in some branches of the military appears to be related to high levels of physical activity during basic training, which usually produce losses in body fat and gains in LBM.

Obese individuals who do not lose sufficient weight or body fat are discharged from the service. However, individuals who lose weight and meet the service retention standards may be at increased risk to regain this weight with advancing age, may encounter increasing difficulty in achieving the body fatness standards, and may consume more resources in the form of weight reduction programs or in administrative costs for separation from the service.

Women have a higher percentage of body fat than do men. Frisancho has documented the gender-related difference in body composition based on data from the National Health and Nutrition Examination Survey NHANES I and II.

For individuals 25 to 54 years old of average frame, fiftieth percentile triceps skinfold thicknesses ranged from 11 to 15 mm for men and 19 to 30 mm for women depending on height and weight.

The corresponding ranges for subscapular skinfold thicknesses were 13 to 18 mm for men and 12 to 29 mm for women. Lohman reviewed data on skinfolds and body density and the relationship to body fatness and concluded that skinfolds predict body density with standard errors of measurement close to that expected based on known biological and technical factors.

Most of the error was associated with variance related to age and gender. The biological variation in predicting body fat from densitometry was estimated at 3. Based on densitometry, Smalley et al.

These results from the general U. population thus provide the rationale for current gender differences in body fat standards in the military services.

The majority of studies evaluating body composition have been done in Caucasians. Many investigators have recognized that the methods currently used do not accurately predict body composition in Blacks, and their applicability to other racial and ethnic groups, such as Asians, Hispanics, and Native Americans is uncertain Malina, ; Mueller et al.

A number of speakers at this workshop discussed the problems of measurement of body composition in racial and ethnic groups see Chapters 6 , 10 , 11 , and There is general agreement that Blacks have relatively greater bone mineral mass, and there is some evidence that muscle mass may be different in Blacks and Caucasians Cohn et al.

Formulas for calculating body composition that have been developed predominantly from Caucasians or even from mixed groups may not adequately predict body composition in racial and ethnic subgroups.

The problem is further complicated by marked differences in body composition depending on socioeconomic status Bray, ; Cohn, a; Goldblatt et al. Some of the observed differences in body composition may also be explained by the fact that the socioeconomic status of Blacks on the average is lower than that of Whites.

Evaluating differences in ethnic groups is also complicated because new immigrants have smaller stature and lower body weights than do later generations see Chapter The rationale for current standards for body weight and body composition in the military is that these measures are correlated with performance of military duties, appearance, and overall health.

In contrast to past standards, which were designed to exclude underweight or chronically ill individuals from active duty, the primary concern of the current standards is to address excess weight in the military population.

Specifically, excess weight or body fatness is thought to impair military performance. Since and particularly since , weight standards have been used to ensure that all personnel are able to meet the physical demands of their duties under combat conditions and to present a ".

trim military appearance" AR , The Army further states that excessive body weight ". denotes a lack of personal discipline, detracts from military appearance, and may indicate a poor state of health, physical fitness, or stamina" AR , The relationship of body weight and composition to performance in the military is addressed below and a discussion of appearance standards follows.

Indicators of physical performance currently used by the military services are shown in Table The relationship of body weight and various components of body composition to successful performance of these activities varies with the activity. In most tasks involving physical work, objects—including the body—must be moved through space.

The greater the body weight in general, the more energy that must be expended simply to move the body see Chapter 7. Cureton et al.

These authors found with this added-weight model that with increased body weight there was a decrease in running performance. The changes in oxygen consumption and running time reported in Cureton's study were similar to those seen with cross-sectional studies done with volunteers with different body weights.

These results suggest that an added-weight-based performance model used by Cureton et al. Studies conducted by Vogel and Friedl, and separately by Harman and Frykman see Chapters 6 and 7 , also suggested that excess weight diminishes running performance and that, conversely, lower body weight is associated with relatively better running performance.

Because sit-ups and push-ups involve lifting the body, these studies indicate that increased body weight is associated with lesser performance. Therefore, as supported by the work of Harman and Frykman Chapter 7 , smaller, lighter-weight individuals do well with these tasks of muscular strength and endurance.

Unfortunately, performance on the standard physical training PT test does not correlate well with measures of military performance, because there is little need for unloaded running, sit-ups, or push-ups in normal daily military activity.

Although overweight individuals do relatively poorly and underweight individuals do relatively well on PT tests, the usefulness of these measures as a predictor of military performance is limited. Unlike measures in the PT tests described above, load carrying ability and lifting have a more direct relationship to military performance.

Harman and Frykman Chapter 7 noted that moderately overweight individuals performed reasonably well in load carrying ability as assessed by km marches with packs. In contrast, underweight individuals frequently underperformed. These authors noted that LBM was the best predictor of load carrying and lifting abilities, as discussed below.

These authors also described studies of the ability to push loads and produce torque and concluded that underweight individuals perform relatively poorly on these tasks, while overweight individuals generally perform adequately, perhaps due to their relatively greater LBM. However, both load carrying and lifting ability, as well as performance during running, sit-ups, and push-ups, are impaired in significantly obese individuals.

As noted above, the compartments of the body may be divided into LBM and BFM. Some of the speakers noted that being underweight and overfat is a problem that may be more significant than overweight as a predictor of poor military performance, which further emphasizes the importance of distinguishing overweight from overfatness.

The data are quite clear that the best correlations of all aspects of physical performance are with LBM. Cureton Chapter 5 found that exercise performance of fit, normal-weight individuals decreased with increasing weight added by a weight belt and shoulder harness.

Their performance was similar to that of obese individuals of similar LBM, but greater body weight. Harman and Frykman see Chapter 7 discussed the relationship of LBM in a variety of tasks relevant to military performance.

LBM was the best predictor of performance capability as assessed by maximal aerobic capacity, treadmill run time, and minute run distance.

These studies pointed out that body fatness was not a strong predictor of run time on an individual basis. Fatness was associated with longer load carrying time to cover a given distance, and LBM was associated with faster load carriage time.

Thus, lean individuals with a small LBM, or obese individuals with a high body fatness, would be expected to do poorly on load carrying tests. These studies also found a low but positive correlation of percent body fat with lifting ability, probably because individuals with more fat tend to have greater LBM.

As described above, LBM is positively associated with the ability to push, carry, and exert torque. LBM was a better predictor of performance ability with these tasks than was percent body fat.

There was a weak trend for fatter people to push and exert torque better, probably because they could use their fat mass to generate momentum. Harman and Frykman Chapter 7 concluded that minimum LBM standards may be more important to military performance than are maximum percentage body fat standards.

They suggested that recruits should be required to meet standards for both minimum LBM and maximum percent body fat. They further suggested that recruits be required to pass physically demanding performance tests that closely simulate military tasks before entry into the service.

Many police and fire departments currently require such tests before accession. There is a lower level of physical performance for the average woman versus the average man, due in large part to the lower LBM and not to differences in body fat.

Cureton see Chapter 5 evaluated running performance in men versus women and found that most of the difference in performance could be explained by the differences in LBM, but there were also differences in energy efficiency during running. He stated that other investigators have not found this difference in running efficiency, so more research is needed to determine if all of the differences in performance between men and women.

can be explained on the basis of differences in LBM, or if there are more fundamental differences in muscle function. In contrast to the findings above, Jones et al.

Chapter 9 found that increased body fatness had a weak but positive correlation with lower run times in women trainees. The explanation for this finding is not clear, but may relate to the greater LBM of the somewhat fatter women. By having more stringent body fat standards for women, women inducted into military service are selected for performance abilities closer to those of men than to those typical of the average American woman.

These less-fat women service personnel may be better able to carry out the tasks involved in normal military operations. Jones et al. Army trainees at Fort Jackson, South Carolina, in two studies in and Women trainees suffered significantly more injuries than did men 50 percent versus 27 percent.

These injury rates, however, did not correlate with body fatness. In both men and women, there was instead a significant correlation of injury rate with body mass index BMI.

Individuals at the lowest quartile and the highest quartile of BMI had significantly greater injury rates than did individuals in the middle two quartiles. Jones also found that greater aerobic fitness, as measured by 1-mile and 2-mile runs, was strongly associated with a decreased risk of injury.

However, he pointed out that despite the correlation between poor fitness and injury and between poor fitness and fatness, there was no correlation between fatness and injury. Chapter 9 speculated that women and men with a low BMI do not have sufficient muscle mass to endure vigorous physical training under the conditions present in military basic training programs.

Again, this seems to suggest that the absolute amount of LBM is a critical factor and provides justification for assessment of LBM and physical performance ability in military recruits before accession. BMI is related to all causes of mortality and increased morbidity from specific diseases such as cardiovascular disease, hypertension, and diabetes mellitus.

Bray reviewed a number of prospective and retrospective studies that included data on the effects of being overweight on health. Bray concluded that fat distribution, particularly increased abdominal fat, was a more important risk factor than overweight for morbidity and mortality.

Mortality ratio and body mass index. Data from the American Cancer Society study have been plotted for men and women to show the relationship of body mass index to overall mortality.

In particular, as shown in Figure , there is an increased risk of hypertension, gall bladder disease, and diabetes with increased abdominal fat. The percentage of the population affected increases with greater obesity.

Given the high cost of obesity in terms of health risk, Bray recommended large-group behavior modification in the work place as the most cost-effective treatment for obesity. Relationship of the abdominal waist to gluteal hips circumference ratio to various risks of obesity.

Copyright , George A. Bray, M. Used by permission. Body fat distribution may be more important than total body weight or body fatness as a risk factor for several diseases including hypertension, diabetes, and cardiovascular disease. Increased abdominal fat, as assessed by a high waist-to-hip circumference ratio increases health risk for these diseases.

Complicating these observations is the fact that body fat distribution differs among racial and ethnic groups Cohn et al.

Few studies have addressed the health risks of different racial and ethnic groups with similar degrees of abdominal overweight. Evaluation of ethnic group differences is complicated by the fact that new immigrants have a smaller stature and lower body weights than do later generations see Chapter Furthermore, some of the factors that are said to predict health risks are different among ethnic groups.

Haffner et al. Stevens et al. Recent research Dowling and Pi-Sunyer, also indicates ethnic variability of these risk factors. More research is needed in this area. Part of the rationale for a body composition that is, body fat standard in the military is that, according to AR and similar statements from the other services, all personnel are to ''.

present a trim military appearance at all times'' AR , A "trim military appearance" is a subjective criterion that is difficult to define in any scientific sense. Currently, this determination is made by local commanders who are not provided with standardized criteria on which to base their decisions.

Although there would be little trouble finding consensus among multiple observers on grossly obese or overweight personnel in terms of meeting an appearance standard, a direct generalizable relationship between body fat content and military appearance is not likely to be observed.

Not everyone stores fat in their body the exact same way. It is also subject to human error depending on who is performing the test.

Bioelectrical Impedance Analysis BIA uses a low electric current that travels through the body to estimate fat free mass.

Since electricity can only travel through water, and each bodily tissue contains varying amounts of water, the flow of the electric current is impacted by the conductivity of each tissue type. For example, muscle holds more water than fat, so the flow of the current becomes less interrupted low impedance when a person has more lean mass and more interrupted high impedance when they have more body fat.

Because of the way these tools function, hydration status can significantly impact the accuracy of the results. There are multiple types of BIA tools available on the market. Many are portable and extremely affordable, including bathroom scales and handheld machines.

There are also more advanced BIA machines that use electrode placement on the body. Hydrostatic or underwater weighing is a form of densitometry that uses your body weight on land and in water, along with water displacement to estimate your body composition. This method is based on Archimedes' principle, the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object.

Muscle does not weigh more than fatbut it is denser and takes up less volume per pound. In other words, muscle sinks and fat floats, so a person with more muscle mass will weigh more underwater than a person with a higher percentage body fat 789.

When performing underwater weighing, a person is required to expel all air from their lungs during the test, as any extra air will impact water displacement. The test is typically repeated three times and the average underwater weight is used.

To get a Hydrostatic body comp test look for fitness companies or online companies that have a traveling van or station on site to perform the test. Air displacement works similar to water displacement except an air controlled chamber resembling an egg-shaped pod is used.

A BodPod uses a mechanical diaphragm to create small volume changes in a confined and controlled space and then measures pressure responses.

A person's weight, age, gender, and height are recorded before the test and the chamber is calibrated. Then using the basic understanding, density equals mass over volume. Volume is measured using air displacement in the BodPod.

Then since both fat mass and fat free mass have known densities, the BodPod can estimate how much fat mass and fat free mass a person has. To get a BodPod test, you'll need to find a facility that will perform the test for you, and this is no easy feat.

Most BodPods are found in medical or health facilities and are not widely available to the public. A DXA or DEXA scan is the most accurate and advanced form of body composition analysis available. It uses x-ray technology to scan your body and provides a detailed assessment of how much muscle mass and fat mass you have down to the poundand exactly where fat and muscle is stored on your body.

For example, if your right arm has 0. This also means a DEXA scan will differentiate between subcutaneous and visceral fat. It can even tell you your bone density. Knowing your body composition is the first step in transforming your body and understanding your progress.

Check back every 8 to 12 weeks more frequently if using an at-home body composition scale to see if your body fat percentage or muscle mass is changing. And then fine-tune your nutrition and fitness habits based on your body composition results.

Diet and exercise both play a key role in improving your body composition, with nutrition making the largest impact. If you want to lose body fat, learn your daily calorie goals and start tracking your intake. Using a nutrition tracking app is one of the easiest ways to learn your calorie and macro goals, and to track your progress.

While calorie control is crucial for changing your weight, your macro balance is critical for supporting your body composition goals. If looking to lose weight, your goal is to lose more fat than muscle, and when gaining weight your goal is to gain more muscle mass than fat - and macros can help you achieve this.

Your unique macro requirements are dependent on your age, height, weight, gender, starting body composition, how much you exercise, and your individual health needs. And adjust fat and carbohydrates according to the type and amount of exercise you engage in. Once you know your goals, you can then track your daily macro intake using a nutrition tracking app to ensure you are staying on top of your nutrition needs.

You can easily get your daily macro goals using an online macro calculator or with a macro friendly tracking app. Exercise is not just to burn calories and fat, when looking to build or maintain muscle massthe type of exercise you choose becomes pretty important.

Just moving more can help you burn calories and lose body fat, but in order to build muscle you need to incorporate strength or resistance training. Lifting weights is a great way to support your lean mass and help you burn fat. Lastly, consistency is everything. Anyone can stick to a plan for a few weeks, but the real changes happen after months of consistency and hard work.

Of course this doesn't mean that you need to change everything all at once or suffer to see changes in your body - its finding the small adjustments that work for you and continually working on improving. Pick a small goal, like hitting your daily macros, and keep working on that one thing until you master it.

Then reassess your goals to add new ones or fine tune existing ones as needed. You also need to be patient and give your body time to see results. You cannot change your body composition in just a few weeks, it takes time and dedication.

You get out what you put in, so hang in there and be patient. The body of your dreams is coming. Want to make things easier on yourself?

The Truth Behind Body Weight and Body Composition - canfitpro

The weight on your scale measures how heavy you are in pounds or kilograms. Your BMI is a common measurement that healthcare providers use to quickly analyze your health data. It's worth noting that the BMI measure is outdated and flawed because it makes assumptions about your overall health by only considering two factors: your height and weight.

Specifically, your BMI is a ratio of your weight and height. A BMI chart breaks down this ratio into four categories:. Body composition offers a much more thorough assessment of your health than body weight or BMI because it measures what percentages of fat and lean mass make up your total weight.

While two people might weigh the same, they could have completely different body compositions. Having a well-balanced body composition sets you up for long-term health success. Body fat is necessary for survival and helps insulate protect you from extreme temperatures, cushions your organs, and stores energy.

However, too much body fat can decrease your quality of life by putting you at risk of sleep apnea , breathing problems, and body aches. If your body has a higher body fat percentage, you may also be at an increased risk of developing cardiovascular heart diseases , type 2 diabetes , several types of cancer, and premature or, early death.

That said, keeping your body fat low is more important than having a lower body weight. Your body fat can also vary by age. Your provider can also take all of these factors into account when helping you learn about your body composition and identify imbalances in body fat and lean mass you may have.

There are several different tests to measure body composition. Your healthcare provider can help you decide which assessment is best for you. Your options may include:. It's important to note that some people use weight scales to measure their body composition.
