MONITERING BODY FAT
Medifit Biologicals prefers medical grade method to monitor the body fat percentage as follows. Medical methods used are highly sophisticated, accurate and widely accepted by medical fraternity.
DUAL ENERGY X-RAY ABSORPTIOMETRY (DEXA)
X-ray beams pass through different body tissues at different rates. So DEXA uses two low-level X-ray beams to develop estimates of fat-free mass, fat mass, and bone mineral density. DEXA is typically only used for this purpose in research settings.
- Equipment is expensive and cannot be moved
- Cannot accurately distinguish between different types of fat (fat under the skin, also known as “subcutaneous” fat vs. fat around the internal organs, or “visceral” fat)
- Cannot be used with pregnant women, since it requires exposure to a small dose of radiation
- Most current systems cannot accommodate individuals with a BMI of 35 or higher
COMPUTERIZED TOMOGRAPHY (CT) AND MAGNETIC RESONANCE IMAGING (MRI)
These two imaging techniques are now considered to be the most accurate methods for measuring tissue, organ, and whole-body fat mass as well as lean muscle mass and bone mass. CT and MRI scans are typically only used for this purpose in research settings.
- Allows for measurement of specific body fat compartments, such as abdominal fat and subcutaneous fat
- Equipment is extremely expensive and cannot be moved
- CT scans cannot be used with pregnant women or children, due to the high amounts of ionizing radiation used
- Some MRI and CT scanners may not be able to accommodate individuals with a BMI of 35 or higher
