    Body Composition for Men

    The photos I've included in this guide are photos of the members of John Stone Fitness who have measured their body fat percentage in some manner (see next post), but whether that measurement accurately reflects that person's true body fat percentage, I can't say for sure. Usually, when a body fat percentage is reported, it's from a calculation by skinfold measurement via calipers.

    If you have pictures you'd like to have addded to this gallery, where the body fat percentage has been measured, and you can calculate your BMI, please send me a private message and I can add you into the appropriate spot. If I've added your pictures into this gallery and you'd like them removed, please also send me a message. Click on the user's name to reach their media gallery thread (or a link to his member profile).

    The Body Mass Index
    The body mass index is sometimes used to by doctors and other professionals as a measure of body fat. It does not, in fact, measure body fat, but because it is a quick and uncomplicated measure, it is used (sometimes inaccurately) to make some guesses about health risks in certain circumstances. Calculate your BMI
    The BMI chart is often divided into sections and labelled as follows:
    Obese = BMI of 30 or greater
    Overweight = 25-29.9
    Normal weight = 18.5-24.9
    As you will see from the photographs, these descriptors are not accurate in many cases, and are a very poor tool to assess health risk. In this circumstance, I simply use them as a measure of relative frame size. You can use this chart to see what weight corresponds to your height at a certain BMI level.

    Similarly, here are some values to determine possible incidences of being underweight. The WHO Expert Committee on Physical Growth has suggested the following classifications:
    mild underweight (BMI = 17.00-18.49 kg/m2),
    moderate underweight (BMI = 16.00-16.99 kg/m2), and
    severe underweight (BMI < 16.00 kg/m2).2

    Body Fat Percentage
    The ideal range of 5 to 25% body fat percentage accounts for nearly all healthy men. Of course, this is a huge range, and some of these values may be more aesthetically pleasing than others.
    over 25% - obese
    18 to 24.9% - acceptable level
    13 to 17.9% - men who are fit
    5 to 12.9% - most male athletes and fitness models
    Near the lower range of the body fat percentage scale, it becomes unsafe to maintain this level for more than a few hours or days.

    Measuring Body Fat Perentage
    Your body is made up of two components: lean body mass, which is the sum of the weight of your bones, muscles and organs, and fat mass. Your body fat percentage measures what proportion of your weight is made up of fat.

    The most accurate way to measure body fat is to use a DEXA scan. DEXA uses a whole body scanner and two different low-dose x-rays to read bone mass and soft tissue mass. It takes about 10-20 minutes to do a body scan. It provides a high degree of precision with a 2-3 % margin of error.

    Another precise method is hydrostatic weighing (underwater weighing). Your examiner first calculates your body density by measuring the amount of water you displace when you immerse yourself in water. Then a formula is used to calculate body fat based on your body density. The problem is finding a facility (University, major gym or fitness center) which has a hydrostatic weighing tank. The margin of error is around 2-3%, but the accuracy depends on the amount of air you expel.

    Measuring body fat with a set of body fat calipers is the most cost effective way to determine fat levels. Calipers are a pincher-like device that are used to pinch your skin in specific locations on your body, such as your waist. These measurements then are placed into a formula which calculates your estimated body fat percentage. Some formulas require 7 point measurements, some require 3 point measurements, and some use a value in between there. See the Body Tracker site as an example. Skinfold measurements are available at most gyms or health clubs that have certified fitness instructors. Skinfold measurements are only reliable if they are done correctly by experienced people. It can be as accurate as the other methods mentioned, but usually it is not.

    Body fat scales claim to measure body fat quickly and conveniently. These body fat scales use the Bioelectrical Impedance method to measure your body fat percentage. A low-level electrical current is passed through the body and the "impedance" or opposition to the flow of current is measured. The result is used in conjunction with your weight and other factors to estimate your body fat percentage. Only by following strict rules can, we may be able to get an accurate measurement of our body fat using these scales. This method can be accurate (4% margin of error) but the results are affected by hydration, food intake and skin temperature.

    The FitTogether Body Composition Report and the US Navy Circumference Method claim to determine your body fat percentage based on comparisons of your height, weight, and various girth measurments. These tests, though they often claim to be accurate within a few percentage points, quite often give markedly different results than those obtained by skinfold measurements.

    Links:

    Body For Life lists a body fat percentage for most of the photos in their before and after section. From looking at the pictures compared to other reported figures I've seen, I quite often feel that they overestimate the "before" number and they underestimate the "after" number.

    Here is a Body Fat Percentage Guide for Men, prepared by Jeremy Likness.

    Interesting!

    The problem I suppose is that people have different ideals about body weight, fat percentage, build, etc.. What looks good to me might look bad to someone else. :confused:

    Yes.
    Originally, I had some descriptive statements in some of the posts, but I took them out because I realized they were judgments, and not facts. Some people think a body fat below 10% is more attractive, and some people think a body fat percentage at a more moderate level is more attractive. Likewise with the BMI. The more examples I can get at different body fat percentages, the better people will be able to decide their own personal targets.

    Guava, I think this needs to be reworded, it's not really accurate. I know you know that BMI doesn't measure body fat, and we definitely don't want to confuse/misinform anybody reading this..

    It's really just just a calculation of a height/weight ratio. It's calculated by weight in kg / height in meters squared.

    I'm not sure yet of the best way to word this exactly..I'll try to think of something. You might want to mention that it is often incorrectly used in place of a body fat measurement because it is easier to calculate.

    I don't know...just don't say it measures fat. It's used (incorrectly) as a (very inaccurate) estimate of adiposity, but it doesn't really measure it. At all.

    Thanks Andrew. I wasn't happy about that wording either.
    I changed the description above, but let me know if you can come up with something a little more clear.

    This is a pretty cool thread Guava. It's neat to see how different bodyfat percentages look on different size people.

    And yay, I have the highest BMI for my before photo so far, I am so proud. :claphigh:

    Guava,..Just ran across this,..Very good idea,...It really helps us new to the lifestyle, to understand what we are looking at, or for. As mentioned beofre, different body shapes and sizes show fat differently,...This really helps,...

    Thanks much,...>>>--->

    Guava...take alook at my avatar...the site calculators I've used (U.S. Navy and others) list me at 20 to 22 percent bodyfat.

    Ya think???:eek: :(
