Obesity and its negative effects on our collective health has been covered repeatedly in the news. There are ways of defining being overweight or obese, most based on height, weight and body mass index (BMI). Body composition is another means of analyzing percentage of body fat, and another tool to help guide and follow treatment.
Let’s start with the numbers: accurate weight and height are a starting point. Getting your body mass index (which you can do here once you have your height and weight) is helpful in determining whether your weight is appropriate for your height. But to be truly accurate about weight, body fat and its affect on health, knowing what percentage of your body tissue is fat specifically can be helpful. Here is where radiology can help: DEXA is the most accurate means of assessing body composition.
DEXA is known most commonly for measuring bone mineral density. This can identify those with osteoporosis or those beginning to show signs of bone loss. Knowing your bone mineral density is increasingly important with age, and preventing fractures is a goal.
DEXA (or Dual Energy X-ray Absorptiometry if you want to know the words behind the acronym) is the most accurate method of assessing body composition. A DEXA scan is a medical test and is considered the Gold Standard in body composition testing with over 99% accuracy. This imaging technique using low dose x-rays can evaluate bone density, fat density and lean body mass. DEXA gives a total picture of body composition, useful for planning a course of action and then seeing the success (we’ll think positive!) of those actions.
Eating well, exercising regularly, talking to your doctor or consulting with a dietician are all actions that can help you on the way to better numbers. Decreasing body fat percentage while maintaining healthy lean body mass is the goal. Decreasing body fat percentage is as significant as overall weight loss to your health.
So start with your numbers and move from there. You have the power to get yourself on the road to your best possible health! And we’re happy to help in any way we can, from sharing healthy recipes to exercise tips and tricks to advising you on your DEXA scores to cheering you on and educating you along the way!
