VEI Check · Body Composition

Muscle and fat balance before the scale:
body composition testing

The body composition test uses multi-frequency bioelectrical impedance analysis (BIA) to quickly look at the balance of muscle, fat and body water. It reveals details of your body's makeup that weight alone cannot, and we use it to guide your exercise, diet and body contouring care.

What We Measure

This non-invasive test is done fully clothed: you stand barefoot on the footplate and hold the hand grips.

Skeletal muscle mass and lean body mass
Body fat percentage and fat mass
Estimated visceral fat and abdominal indicators
Segmental analysis (balance of arms, legs and trunk)
Body water (intracellular and extracellular) and phase angle (depending on the device)
Basal metabolic rate and reference targets for weight and muscle

Who It May Suit

People who want a baseline for weight management or exercise planning
People who want to check changes in their body regularly during care
People who also want to check metabolic health, such as blood pressure, blood sugar and lipids, as needed
People who want to keep a record of their body composition during body contouring care

Before Your Test

Avoid large meals for 2 to 3 hours before the test and drink fluids as usual
Avoid alcohol for 24 hours and vigorous exercise for 8 to 12 hours before the test
Empty your bladder within 30 minutes before the test
Remove metal accessories and wipe off any lotion or cream on your hands and feet
Menstruation, swelling or acute illness can affect results, so we discuss rescheduling if needed

How a Visit Works

The visit takes about 15 to 20 minutes, including a review of your results. Re-measurement is usually done every 4 to 8 weeks or according to your care plan.

Check-in and consultation: we review your goals, medical history and medications
The measurement is taken with shoes and socks off (about 2 to 3 minutes)
We explain the key numbers and give practical advice on protein intake, activity and hydration
We schedule your next measurement and, when needed, move on to a weight management consultation or other care

Who Should Talk With Us First

People with a pacemaker or other implanted electronic device (we do not perform the test because it uses an electrical current)
People who are pregnant (we discuss timing or other options)
People with wounds or infection at the contact areas, or a severe fluid imbalance

The VEI Clinic Approach

An internal medicine specialist reviews your body composition results with you and, when needed, links them with other tests such as blood work to set a care plan.

What body composition numbers mean and how to manage them can vary from person to person, and the specialist decides after your consultation which care is suitable. This test is not emergency care, so if you have emergency symptoms, call 119 or go to an emergency room.

FAQ

Frequently asked questions

How long does the test take?

The measurement itself takes about 2 to 3 minutes, and the whole visit, including consultation and results, takes about 15 to 20 minutes.

Why do my results vary slightly each time?

Meals, hydration, exercise, alcohol, menstruation or swelling can affect the results. Preparing the same way each time makes changes easier to compare.

How often should I be measured?

Usually every 4 to 8 weeks, or as set by your care plan.

Can I be tested if I have a pacemaker?

Because the test uses an electrical current, we do not perform it for people with a pacemaker or other implanted electronic device. We will discuss other ways to check.
