DEXA Body Composition Scans for Optimizing Health

Dec. 6

There’s no shortage of tools to measure our fitness. Watches, rings, scales, CGMs, and blood pressure cuffs cover a lot of bases. But, if you're seeking a comprehensive understanding of your body's internal composition, there's no better tool than the DEXA scan.

What is a DEXA scan?

Originally designed to evaluate bone density, the DEXA scan has evolved into one of the most reliable methods for body composition analysis. It uses two different X-ray energies to take images of the body, allowing it to differentiate between bone, fat, and lean tissue.

Why Get a DEXA Scan?

Precision and Consistency: DEXA is the gold standard for body composition analysis. Unlike other methods, which can vary significantly depending on hydration levels or meal timing, DEXA offers consistent results. It’s the difference between a rough estimate and a precise assessment.

Bone Health: Given its roots in bone density measurement, DEXA provides valuable data on bone health. This is particularly important for women aged 35-60—as they transition through menopause, a phase when bone density often declines. Healthcare providers use DEXA scans to help identify osteoporosis.

Segmental Analysis: Ever wondered if your right arm has more muscle than your left? Or how the muscle distribution in your legs compare? If you’re a fitness buff, you’ll love that DEXA compares one limb to the other, enabling you to adjust your training to achieve the perfect symmetry of Arnold Schwarzenneger.

Beyond the numbers

Metrics like weight and BMI (Body Mass Index) can be deceptive and are comparable to a good guess. A person might fall within a "healthy" BMI range but have a high percentage of body fat and low muscle mass—posing significant health risks. Conversely, someone with a higher BMI might have a muscular build and low body fat, making them far healthier than the numbers might suggest. DEXA gives you the whole picture without the guesswork. A clear and accurate understanding of your body weight, visceral fat, lean tissue, and skeletal health.

What This Means for Your Health

Understanding your body composition has profound implications for health and longevity:

Metabolic Rate: Lean mass burns more calories than fat, even at rest. Knowing your precise amount of lean mass can help determine your resting metabolic rate, and whether you may want to make changes to improve it.

Know Your Risk: A high percentage of body fat, especially visceral fat (the kind stored deep in your belly, surrounding internal organs), is associated with a greater risk of chronic diseases like heart disease and type 2 diabetes.

Personalized Fitness and Nutrition: With a detailed understanding of your body's composition, fitness and nutritional plans can be tailored to your needs. Whether the goal is to build muscle, lose fat, or maintain your current body composition, DEXA provides the blueprint.

In a world where health advice is ubiquitous and hard to trust, the insights from a DEXA scan offer personalized and actionable data that you can rely on. If you genuinely care about your health and want a deeper understanding of your body, a DEXA scan provides a clear picture of what’s happening beneath the surface. Not just what the scale says.
