How to Prepare for Your Appointment

DexaFit Body Scan
Click each item to read the instructions
1) Fasting & Activity
Fast for 2 hours prior to your scan. Limit physical activity (no exercise) and stay hydrated.
2) Clothing
Wear athletic attire or casual clothing without any metal.
3) Remove Metal Items
You’ll be asked to empty your pockets and remove metal items like watches, belts, glasses, and jewelry.
4) Supplement Restrictions
Avoid taking any calcium supplements in the 24 hours prior to the scan.
5) Recent Imaging Restrictions
No gastrointestinal contrast, barium or other contrast mediums and radionuclides within 7 days of your appointment.
6) During the Scan
During the scan you will relax on an open-air DEXA scan table. The process is quick and uses minimal radiation, equivalent to about four bananas worth of exposure, or a few hours of natural background radiation. The DexaFit scan is a straightforward, non-invasive procedure designed for your comfort and convenience, providing valuable insights into your body composition.

VO₂ Max Fitness Test
Click each item to read the instructions
1) Fasting & Activity
Fast for 3 hours prior to your test (water is fine). Limit your physical activity before your visit (no exercise). Get adequate sleep the night before.
2) Clothing
Wear workout clothes and athletic shoes (the test is done on a treadmill or a Peloton bike).
3) Stimulant Restrictions
Avoid taking any caffeine or stimulants the day of your test.
4) During the Test
During a VO₂ Max test, you’ll perform a graded exercise test on a treadmill or bike, starting at low intensity and gradually increasing to your maximum effort. You’ll be fitted with a mask that measures your oxygen consumption and CO₂ output, providing data on your aerobic capacity. The test is designed to safely determine your fitness level under careful monitoring.
RMR Metabolic Test
Click each item to read the instructions
1) Fasting & Activity
Fast for at least 5 hours prior to your test (water is fine). Limit physical activity (no exercise) beforehand. Get adequate sleep the night before (the test is ideally performed in the morning).
2) Clothing
Wear comfortable clothing. Casual and even business attire are also acceptable for this test, as you will just be relaxing in a chair.
3) Stimulant Restrictions
Avoid taking any caffeine or stimulants the day of your test, and avoid alcohol and smoking for at least 48 hours beforehand.
4) During the Test
Your RMR accounts for about 70% of your Total Daily Energy Expenditure (TDEE). Knowing it is essential for accurately gauging your daily calorie needs. This information is critical whether you’re aiming to lose weight, build muscle, or maintain your current state. It’s the foundational number on which your nutrition and fitness plans should be built.

Red Light Therapy
Click each item to read the instructions
1) Hydration
Drink plenty of water before and after your session.
2) Skin
Skip heavy makeup, and don’t apply oils, lotions, or moisturizers within an hour of your session, since they can keep the light from reaching your skin.
3) Clothing
Wear light clothing such as shorts, a tank top, a sports bra, or a bathing suit. You won’t fully undress. Bring your own eye protection if you like.
4) During the Session
You’ll lie flat on a table for up to 20 minutes. 15 to 20 minutes a day is the most you need; more time does not add more benefit.
Red light therapy is a service of DexaFit Burlington, an independently owned and operated Licensed Operator of the DexaFit brand.
