When is the best time to test for a scan?

Whilst not always possible, the best possible time to scan would be under the following conditions:

  • First thing in the morning after emptying the bladder
  • In a fasted state (i.e. no food)
  • Well hydrated
  • No consumption of caffeine or caffeine-containing supplements
  • No training or activity that raises body temperature

How does BIA technology differ from a DEXA measurement?

BIA uses a multi-frequency currency to measure the resistance of the current flowing through tissue.  DEXA is a dual-energy x-ray that measures the density of tissue and is the gold standard of Bone Density measurements in medicine.

Whilst the BIA system has been validated in scientific literature as having a high correlation with the DEXA, there will still be variances between a BIA and DEXA which could be due to:

  • Different time of the day
  • Different food contents & hydration as well as medications or supplementation that read differently through the resistance of BIA
  • DEXA treats breast implants as a foreign tissue and is included in the bone measurement whereas BIA treats breast implants as fat tissue and included in the fat measurement
  • Different DEXA machines can also show quite varied results depending on the brand of DEXA

How does BIA technology differ from a Skinfold measurement?

Skinfold measurements are a measurement of subcutaneous fat only and will never reflect the Total Body Fat measurement on the BIA scan, which also includes visceral fat as well as subcutaneous fat.

Skinfold measurements are subject to a very high degree of inaccuracy and rely on a skilled individual to take the measurements who is qualified in anthropometry.  Unless you can anticipate the exact same skinfold pinch every time, the consistency in readings is often unreliable.

Of course, skinfold measurements are beneficial for physique competitors who use skilled coaches to measure a subcutaneous metric, but, this is only fat tissue under the skin.

Why do results change slightly between different BIA devices?

It is not recommended to compare and track scan results between different brands of BIA devices.

Some brands of BIA use pre-set algorithms so it will not be correctly reflecting your body composition as per your gender, height and age. As referenced in published validated studies, the accuracy of BIA is reliant on 5 factors which are (i) Gender, (ii) Age, (iii) Height, (iv) Weight & (v) Impedance Value.  As with other types of body composition measurement devices such as a DEXA scan, the accuracy of the algorithm relies on population statistics.

We recommend that you use the Evolt 360 Scan as a baseline measurement and keep using the Evolt 360 scan to measure progression in a standardized state.

How often is it recommended to scan?

To ensure consistency of progressive measurements that are consistent with your training and nutrition goals, we recommend scanning every 6-8 weeks.  You should expect to see a result in 4 weeks if you are following the right training and nutrition protocols.

I did a follow up scan and I lost muscle and gained fat?

There are various reasons this scenario can occur. Firstly, you should check whether your nutrition has been sufficient to meet your calorie deficit requirements.

Conversely, it is also common for people to severely reduce calories and increase cardiovascular training in an effort to see significant and quick weight loss.  Severe calorie reductions will mostly see weight lost in skeletal muscle mass and increase in body fat if the training demands are too high.

This scenario can be common in people who commence HIIT style training with severe calorie restriction.

We recommend checking your macronutrient requirements using MyMacros on the Evolt Active App and testing with at least 2 weeks full adherence.

It is also important to check that you scanned under the exact same circumstances as you did previously ensuring the same food consumption, same hydration, same time of the date, same un-trained status, same medications and/or supplements and also the same week in the menstrual cycle (if you are female)

I didn't get the results I was hoping for?

As previously mentioned, it is firstly important that your first and follow up scan is completed under the exact same circumstances being the same time of day, same food consumption, same hydration, same time of the date, same un-trained status, same medications and/or supplements and also the same week in the menstrual cycle (if you are female)

Depending on the time frame between scans and the results you were looking to achieve, ensure that you have followed/checked the following steps –

  • Full adherence to training activity.
  • Full adherence to nutrition strategy inclusive of meeting calorie deficits or surplus and ensuring the right macronutrient break down for your goal.
  • Ensure supplementation and/or medications remain the same during the time frame.

Essentially though, if results are not as expected, changes need to be made to either your training or nutrition protocols.  The beauty of being able to scan on the Evolt 360 is the ease at which you can assess feedback on whether your nutrition and training is right for the goal you are trying to achieve.

I’m competing in Bodybuilding, will the Evolt 360 track my prep?

Yes, the Evolt 360 will track changes for a Physique contest whether it be for a bikini athlete or bodybuilder.

Physique sports such as bodybuilding are judged purely in a physical visibility sense so genetics and muscularity become an important aspect.  In terms of body fat, physique athletes are not judged on a body fat percentage measure so determining body fat for the stage is impossible to ascertain given that some people can look visibly leaner whilst carrying a higher body fat percentage.

From an individual perspective, the physique athlete should use the Evolt 360 to track their progression throughout the contest prep then use those metrics to gauge their progression in future contest preps.

If there is a significant change during the contest prep such as the addition of supplementation or anything that significantly affects hydration, be aware that there may be some inconsistencies in readings.  To ensure consistency and reliability in progressive readings, consistency around conditions must be maintained

I look lean but my body fat is high?

Visible leanness does not always reflect an individual’s body fat percentage.  In other words, some individuals can look leaner than they actually are.  This can be for a number of reasons; however, one reason could be due to the fact that the high body fat is made up of significantly high visceral fat mass which is the fat that surrounds internal organs.  As you cannot see visceral fat visually, this can sometimes be the reason that some people can look leaner than they think.

As previously mentioned, it is important to assess consistency in readings and under the following conditions –

  • First thing in the morning after emptying the bladder
  • In a fasted state (i.e. no food)
  • Well hydrated
  • No consumption of caffeine or caffeine-containing supplements.
  • No training or activity that raises body temperature

Despite body fat reading higher than expected by the individual, the validity and reliability of the Evolt 360 will provide consistency in progressive readings.

Why does my weight and body fat fluctuate throughout the day?

Body composition metrics will fluctuate throughout the day due to changes in blood volume, hydration, gut contents and body temperature.  This is why a standardized protocol for scanning must always be adhered to ensure consistency of scanning results.  Scanning in the morning will differ from scanning in the afternoon or night due to all of these changes that occur.

I am an endurance athlete, why is my visceral fat high?

In some instances, individuals who have significant training loads such as an endurance athlete can sometimes be in an overtrained state and cannot ingest enough nutrients to compensate for the activity expended which can result in hormonal shifts, inflammatory conditions which results in reduced skeletal muscle mass.

Whilst high visceral fat can be attributed to a number of different variables, some endurance athletes can have a higher visceral fat due to an increase in cortisol production and break down of skeletal muscle mass.  Other factors could be genetic in nature, however, unless an individual has scanned using BIA technology or performed a DEXA scan, they would essentially be unaware of their visceral fat level.

Is the BIA scanner safe to use?

Bioelectrical Impedance Analysis has been used in medicine for many years and is safe to use as it does not use any form of radiation.


The EVOLT 360 is a body composition analyser. It provides a quick, non invasive, easy measurement of your body composition delivering a guideline of your lean body mass, body fat mass & percentage, skeletal muscle mass, visceral fat level, fitness age, fitness score plus much more.

Who should not use the Evolt Scanner?

We do not recommend the use of BIA technology for individuals who may be pregnant or have an implant device such as a cardiac pacemaker or implantable cardioverter defibrillator.

What is the difference between Mineral Content and Bone Density?

Bone Mineral Content refers to the calculation of the weight of the bone mineral which can be established via BIA readings.  Bone Mineral Density refers to the density of the bone which can establish a diagnosis of conditions such as Osteoporosis, treatments relating to osteoporosis or risk of fracture injuries.  Bone Mineral Density tests are performed by a qualified radiographer using a DEXA scan.

How do medications affect your result?

Whilst it is important to always scan under the exact same conditions for consistency and repeatability, there are a number of medications that can alter a scan result where the medications significantly change hydration status, blood volume and temperature changes.  The most notable being –

  • Medications that influence ICW / ECW (intracellular water • & extracellular water) and Nitrogen retention – influence interpretation of protein/mineral measures, soft lean mass etc. Creatine, anabolics, beta 3 agonists, peptides etc will influence the result.
  • Hydration status – as in euhydrated in this case and
    influence of things like caffeine intake, pre-workouts,
    diuretics, thermogenics. (dehydrated normally • overestimates body fat).
  • Other medications that may influence blood volume
    including things like Metal Plates, Pins & Gut contents. •
  • Water Compartmentalization including Sodium • and Potassium (intracellular electrolyte) retention particularly from the use of diuretic medications.
    • Iron status – anaemia vs hemochromatosis – high ferritin = increase red blood cell mass = increase blood viscosity = influence BIA interpretation of total body water and lean body mass – as in register higher soft tissue and total body water, therefore, may result in reduced measure of total body fat etc (anaemia may do opposite).
    • Drugs that increase blood flow via vasoconstriction – changes blood volume and ECW / TBW ratio which influences the interpretation of fat mass.
  • Stimulants (Ritalin, Dexedrine, Adderall).
  • Pseudoephedrine (Sudafed).

Will the scanner read me correctly if I use anabolic steroids?

As previously mentioned, steroid medications and other medications that alter hydration status such as creatine, beta 3 agonists, peptides etc. will influence the result where it relates to Lean Body Mass, in particular, Total Body Water.

It is important to always scan under the same conditions each time with the same variables to ensure consistency and repeatability of results.

Will eating a meal before the scan affect my results?

Consuming food will show a minor change in your scan result.  It is always best practice to scan on an empty stomach, however, you can still scan after eating a meal, so long as you re-scan under the exact same conditions each time you scan.


The scan process is easy and takes less than 2 minutes.


You do not need to remove any clothing unless it is heavy or bulky. Shoes and socks must be removed and feet and hands must be disinfected before a scan. Please ensure all items are removed from your pockets. (I.e. Phones, keys, coins etc.)


Once you have completed the scan process you will receive an email. Click on the link and sign into Evolt Active. Your result will be displayed on the “Scan Stats” on your “Profile”.


Place feet correctly, hold handles firm, completing covering palm and placing thumb on the button. Keep your arms off your body and keep still and do not move or speak during your Evolt 360 scan.


The frequency of measurement is fully dependent on each individual or program. Generally, people like to scan every 4-6 weeks to accurately track and monitor their progress to ensure their diet is correct for their training regime. Not only that, it’s super motivating to see your results change!


A full scan explanation can be found on the back of your scan result sheet or login to Evolt Active to view your result online.
