Body Composition & Metabolism Analysis

We Offer Accuracy and Expertise with

Body Composition and Metabolism Testing

This is what makes Bodyology unique in its field of body fat and metabolism testing. We offer unbeatable accuracy of a laboratory technique coupled with expert advice, making sure you get the results and information you need.

Only by accurately assessing body composition and metabolic rates with a test can we know exactly what makes up someone’s weight and energy expenditure. The results of body fat and metabolism testing can then be used to guide individuals regarding nutrition and exercise. A body composition test is the single best way for a person to get the “whole picture” of what’s really going on in their body, and to then make changes leading towards better health.

Body Composition Analysis

Body composition, or fat vs. fat-free (lean) mass, has long been considered by fitness and medical experts as one of the best determinants of health status and disease prediction. Testing can help to determine a person’s overall health. Body composition reflects the results of a person’s physical activity and nutritional practices and a body fat test can be the first step to regaining health. Purely using body weight can be very misleading, because a scale can’t tell the difference between a kilogram of fat and a kilogram of muscle. However body fat testing can determine what is fat and what is muscle.

Sedentary people can easily gain fat and lose muscle without any noticeable change in their weight. A person undertaking an exercise/weight training program may also not experience a significant change in weight, yet their muscle mass is most likely increasing, while they are also probably losing body fat. A body composition test will reveal these important shifts in body composition that a scale cannot.


Your resting metabolic rate (RMR) is the amount of energy (measured in calories or kilojoules) that your body uses at rest. Knowing your RMR is important regardless if your goal is to lose weight, gain muscle, run harder or even taper leading into a key race as is enables you to accurately determine your total energy expenditure, and this determines your diet accordingly. Using a Metabolic Cart (Indirect Calorimetry) is the most effective way to measure your metabolic function in real time where we measure your energy expenditure through your expelled breath.

Ideal % of Body Fat

It is important to acknowledge that a certain amount of body fat is needed to ensure good health and that whilst a test may reveal a high fat percentage and health goals may include reducing body fat, the ultimate goal should not be to try to eliminate body fat. Whilst acknowledging that, it is important to note that excess body fat has been linked to increased prevalence of diseases such as cancer, diabetes, and heart disease.

Impotence and sexual dysfunction, as well as reduced libido, energy levels, and overall quality of life are also often associated with excess body fat which can be revealed by a simple test. Worldwide overweight and obesity numbers amongst adults in developed nations have reached epidemic proportions. And don’t be fooled; Australians are amongst the world leaders. Adding further to this dilemma is the increasing rate of childhood and adolescent overweight and obesity.

Due to differences in visceral fat (deeper fat tissue located around internal organs) levels and body fat distribution, males and females have different levels of desirable body fat percentage. Personal % body fat targets need to be based on an individual age, lifestyle, diet etc and should be done in consultation.

To provide you some guide, below are some % ranges that we typically see at through our testing:

Generally active and healthy balance diet: Men – less than 20%, Women – less than 30%

Highly competitive team sports (rugby, ALF etc): Men 12-17%, Women 20-25%

Highly competitive endurance athletes (triathlon, run, cycle etc): Men 10-15%, Women 15-22%

Body Sculptures and Bodybuilders at competition stage: Men 5-10%, Women 10-18%

The method of Body Fat Testing Matters

There are many options when it comes to a body composition and metabolism testing. Measurement techniques can vary greatly, however many body fat testing methods can become very difficult to perform, are relatively invasive, and many field methods of body fat testing used are highly inaccurate.

Skinfold Callipers and Bioelectric Impedance (as used in body-fat scales) have error factors of up to +/-8%. This means that a Skinfold or Bioelectric Impedance test measurement of 20% body fat could actually be as low as 12% or as high as 28%. Whilst using experienced technicians and following proper protocol can reduce this error, these body fat testing methods still present as problematic.

Inaccurate information from improperly performed body fat testing can be very dangerous if used for developing nutrition and training programs. This exemplifies the importance of using an accurate test method when assessing body composition.

Many potential clients in Melbourne will let pride or fear get in the way of undergoing body composition testing. We suggest that if you are aware that you may be overweight and your goal is to reduce body fat, then it is imperative to get baseline measures with body fat testing so that we can monitor your progress. There is no other way besides a body composition test to determine whether your body is responding to the changes you have made in exercise and nutrition. Without monitoring progress (or lack of progress) with a body fat test, people become locked in cycles of training for zero results. Wouldn’t you want to know if you were wasting your time, and if there were other options to overcome plateaus? A body fat test can give you the most accurate assessment of your progress.
