Technology is advancing to the point where it’s now easier than ever to see just how effective a workout program or weight loss strategy is. With the introduction of DEXA scans in this market, you can get access to a broad range of data points that show everything from your body composition to your visceral fat mass. A DEXA scan is also known as a dual x-ray absorptiometry scan. It passes both low-energy and high-energy X-rays through your body.

Dr. Peter Attia has gained prominence over the last few years through his work in longevity science, metabolic health, and the optimization of human performance. He’s the author of Outlive, and focuses on using applied science of longevity to help his patients live longer and better lives. Dr. Attia has covered the importance of the DEXA scans and the VO2 Max on his book, blog, and podcasts. In this article, we will look at Peter Attia’s work more closely, while zooming on how to use the DEXA scan and the VO2 Max to assess and improve both longevity and healthspan.

What is Appendicular Lean Mass Index (ALMI)? Appendicular lean mass index (ALMI) is a measurement used in body composition analysis to describe the amount of lean muscle mass in the appendicular skeleton, which includes your arms and legs. ALMI is important for general health and longevity. It can be measured with the DEXA Scan.

You’re taking weight-loss drugs, or thinking about it, and want to know how much muscle you lost in the process? The easiest way to find out is to do a DEXA Scan with Fitnescity. Research found that 40% of weight people lose with Wegovy accounts for lean mass. With a DEXA scan and with the proper lifestyle modifications (exercise, increased protein intake), you can prevent muscle loss.

If you’ve been keeping up with the world of fitness, you’ve definitely seen the term VO2 Max before. After being used for decades to help athletes get a better view of their cardiovascular fitness and endurance, the VO2 Max is now becoming gradually mainstream. If you’ve measured your VO2 Max or if you have an estimate from your smart watch, you might be wondering what you can do to increase your number. Here’s what you need to know.

VO2 Max, which is the maximum rate of oxygen consumption attainable during exercise, is known to be a good indicator of cardiorespiratory fitness and exercise performance. However, recent research shows that VO2 Max is also closely linked to longevity. In this article, we’ll explore the relationship between VO2 Max and longevity.

If you've previously done a DEXA Scan and received Bone Mineral Density (BMD) results, you may be wondering how you can improve bone density. Bone mineral density tends to deplete with age, but lifestyle factors can exacerbate the process. However, it is possible to increase bone density. While we always recommend that you follow up with your doctor when it comes to bone health, here are some general tips.

We've previously covered "What Causes Visceral Fat?” and “What Are The Dangers Of Visceral Fat?” Here's what you need to know about reducing Visceral Adipose Tissue (VAT):

• Is there an acceptable amount of VAT?

• How can you measure Visceral Fat?

• How to reduce Visceral Fat

The key to strong bones, improved muscle tone, and reduced fat percentage is lifestyle modifications and a good training program. In order to make that happen, it’s necessary to gain a detailed insight into your body composition. That’s where the DEXA scan steps in. Read on to learn what DEXA is and how it works. When you are ready, visit Fitnescity, the national leader in DEXA Scan and VO2 Max testing.

The show uses a DEXA machine to get a more scientific, data-driven perspective on the impact of these dietary choices. You Are What You Eat brought the DEXA scan under the spotlight, and now a lot of people are interesting in experimenting with these scans themselves. Here's how you can design your own experiments.

The biggest misconception about body fat is that it’s always dangerous and unhealthy. Certain levels of VAT are important because they help protect your organs, surround important blood vessels, and supply blood to abdominal organs. As it cushions the organs, VAT can prevent damage. However, too much VAT is not good for you and may lead to major health problems. Since it can actively increase the risk of health problems, visceral adipose tissue is often referred to as “active fat.” Here are some of the dangers of Visceral Fat.

Visceral adipose tissue (VAT) is a type of fat that is located in the abdominal cavity and wraps around organs such as the intestines, pancreas, and liver. It is called visceral fat because this fat is close to viscera, i.e., internal organs. The abdominal area is quite stubborn. Most people struggle to lose weight in this specific area and find it difficult to tone their stomachs. Excess fat in the abdominal region results from various factors.

Losing muscle when you are attempting to lose weight can affect your health negatively. When it comes to weight loss, it’s important to strive to reach your ideal weight without compromising strong lean muscle. But since increasing muscle mass can in itself lead to weight gain, can you really build muscle while losing weight, and how can you do so?

Hit Netflix Documentary “You Are What You Eat: A Twin Experiment” is creating a big divide between proponents of a plant-based diet and the rest of the world. The documentary is based on a Stanford study that follows 22 sets of genetically identical twins as they go on opposing diets: ominvore and vegan. Amid this debate, many viewers decided to conduct their own experiments, including through the use of the DEXA scan.

New Netflix docuseries, You Are What You Eat, showcases the DEXA scan in a twin experiment. The four-series documentary is based on an 8-week study led by Stanford University’s Christopher D. Gardner. The study puts 22 sets of genetically identical twins on opposing diets and measures progress. Once of the first tests that that TV show highlights at the beginning of the show is the DEXA scan.

Here are the DEXA scan metrics that Dr. Peter Attia uses for his longevity framework:

• Visceral Fat

• Bone Mineral Density

• Muscle Mass

• Lean Tissue: Appendicular lean mass index (ALMI) and fat-free mass index (FFMI)

For a limited time, refer a friend and you will both receive a copy of Peter Attia’s book.

We are excited to share that we've recently made an update to Fitnescity reports.

The new Fitnescity "Snapshot" gives you a summary of all your results.  

The new “Trends” section, a popular feature, allows you to visualize changes in *all* your metrics in one place. 

The new Sports Medicine and Community Health (SMaCH) Lab at The University of Southern Mississippi (USM) has launched a partnership with national testing aggregator Fitnescity to utilize the expertise both entities can provide for wellness assessments.
