Healthy Living Blog: Why Your DEXA Scan Doesn’t Tell the Whole Story about Bone Loss and What to Do Instead with Zora Benhamou

Are you brushing off joint stiffness, hip pain, or that suspicious DEXA scan result your doctor told you to manage with a walk and some calcium? If you are, you are not alone and this conversation is going to change how you think about your bones.

I recently sat down with Zora Benhamou, a gerontologist and founder of the Hack My Age podcast, and this episode stopped me in my tracks. Zora has spent years studying aging and longevity from every angle (biological, psychological, sociological) and she has been extremely public about her own bone health journey, including navigating osteoarthritis severe enough to require hip replacement surgery. She is someone who walks the talk, does all the right things, and still found herself dealing with something most of us never expect.

If you have ever felt confused about bone loss, scared by a diagnosis, or frustrated that the advice you are getting feels woefully inadequate, this one is for you.

What Is a Gerontologist and Why Does It Matter?

Most of us have never heard of a gerontologist, or we confuse it with a geriatric physician. Zora explains it simply: a geriatric physician treats older adults, but a gerontologist studies the entire arc of aging from birth to death. This field looks at why we age, how disease develops across a lifetime, and what we can actually do to change the trajectory. And critically, it is not just about biology. It is about psychology, sociology, community, and lifestyle woven together.

This broader lens is exactly what makes Zora’s perspective so valuable. Because when it comes to bone loss in midlife, it is never just one thing.

Osteoporosis vs. Osteoarthritis: These Are Not the Same Thing

One of the biggest misconceptions Zora clears up immediately is the difference between these two conditions. They are frequently confused, and getting it wrong can delay proper care.

Osteoporosis is the loss of bone density. Your bones become more fragile and porous over time, and the scary part is that you cannot feel it happening. It is often called the silent disease because by the time most women receive a diagnosis, significant bone loss has already occurred. Fractures become more likely, and the consequences (especially as we get older) can be life-altering.

Osteoarthritis is something entirely different. It is not a bone density issue. It is a degeneration of the joint itself: the cartilage breaks down, you lose range of motion, pain sets in, and spurs can develop. It is progressive and deeply uncomfortable. And here is what surprised me most: you can have one without the other. Zora had severe osteoarthritis that ultimately required hip replacement surgery, yet her bone density scans showed strong bones throughout. They are separate conditions with separate risk factors and different solutions.

Zora’s Personal Story: When Doing Everything Right Still Is Not Enough

Zora was first told she had osteoarthritis in her late 40s and, like many of us would, she basically shrugged it off. She had the resources, the knowledge, and the connections, and she went after it with everything she had. PRP injections. Regenerative medicine. Biohacking protocols. For a while, it helped. Pain decreased. She got some range of motion back.

Then menopause arrived, hormones shifted, and the interventions that had been working stopped being enough.

When her doctors finally told her surgery was the only real path forward, Zora says it hit her hard…not just physically, but emotionally. She is the aging-well person. How could this be happening to her?

The answer came down to genetics and risk factors she was born with. She had nine of the twelve known risk factors for osteoarthritis, including a structural bone issue present from birth, hypermobility, hormonal changes from menopause, being female, and a history of athletic injury including a torn ACL she never had surgically repaired. The research showed that exercising had likely delayed surgery, not caused the problem. But ultimately, some things cannot be biohacked away.

This matters because so many women blame themselves. They feel like failures when their bodies do not respond the way they expect. Zora’s story is a powerful reminder that genetics and physiology are real and that sometimes the most empowering thing you can do is understand your starting point rather than shame yourself for it.

What Does Osteoarthritis Actually Feel Like?

Zora says this is a question nobody had ever asked her before, and it is one of the most important.

The early signs are subtle. You start losing range of motion in specific movements like positions that used to feel easy become blocked or stiff. For Zora, who had been hypermobile her whole life, the loss of that range was one of her first red flags. Eventually, getting into a car became a careful, calculated movement. Activities that require hip rotation started requiring a workaround.

Then comes limping…and often you do not notice it yourself. Someone else points it out. Your body is compensating for pain, shifting weight, finding angles that protect the joint.

The critical distinction: normal stiffness from aging is one thing. When movement starts requiring workarounds, when you are reorganizing your daily life around a joint, when someone tells you that you are limping it’s a red flag worth investigating with imaging, not dismissing.

Why Your DEXA Scan Is Not the Whole Story

The DEXA scan is the current gold standard for bone density testing. You lie on a table, a scanning arm passes over you in about five minutes, and it produces a T-score that tells your doctor how your bone density compares to a young adult reference range.

Here is the problem: it only measures density, not quality or strength. Zora references a striking statistic: a significant percentage of people who experience osteoporotic fractures actually have DEXA scores in the normal range. A normal number does not guarantee fracture protection.

Zora advocates for a newer scan called the REMS  (Radiofrequency Echographic Multi Spectrometry) scan. This ultrasound-based technology measures both bone density and bone quality, giving a more complete picture of actual fracture risk. It is non-invasive, radiation-free, and produces immediate results.

To illustrate why this matters: her husband is a fit, 65-year-old man who walked across Europe for 11 months carrying a 40-pound pack. His REMS scan showed osteoporosis by density standards, but his bone quality was very strong. Had he taken only a DEXA, he might have been prescribed medication he did not need.

The takeaway is not to dismiss bone scans. It is to understand that a number is one piece of information in a bigger picture. Are you athletic or sedentary? What are you eating? How is your protein intake? What is your strength training history? These factors matter enormously, and no score can capture all of them.

Why Bone Loss Accelerates After Menopause

Estrogen, progesterone, and testosterone are not just reproductive hormones. They are protective hormones, and one of their critical roles is maintaining bone health. They are anti-inflammatory, they help lubricate joints, and they actively slow the breakdown of bone tissue.

Bone loss actually begins in our mid-thirties…we just do not feel it and typically do not get screened for it until our mid-sixties when insurance may finally cover the test. By then, many women are already well into osteopenia or beyond.

Zora explains that research shows even very small amounts of estrogen in the bloodstream can make a meaningful difference. The threshold for stopping bone loss is low, and the threshold for actively building bone back is not dramatically higher. For women considering hormone therapy, bone health is one of the clearest and most widely agreed-upon benefits.

For women who cannot or choose not to take hormones, Zora is equally clear: HRT is one tool in the toolkit, not the only one. There are absolutely other paths to building and protecting bone, and she outlines all of them.

What Actually Works to Build Bone Density

Impact and Load

Bones need a mechanical signal, like a force, to stimulate new bone formation, and that signal has to be strong enough. Walking produces about one to one and a half times your body weight in force. Running gets closer to three times. To trigger meaningful bone building, research suggests you need approximately four times your body weight in force.

Jumping off an eight-inch step produces about four times your body weight. Adding a small rebound after the jump pushes it to five times.

The protocol Zora references is surprisingly simple: jump off a step 10 times, rest briefly, repeat for three rounds. Three times per week. Research cited in the episode showed approximately a 1% increase in hip bone density in six months using this approach.

An important caveat: if you already have significant bone loss or joint issues, please work with your doctor before starting any jumping or high-impact protocol. Build gradually and get cleared first.

Strength Training

Lifting heavy weights does two things for bone: the muscles pulling against the bone during contraction send a building signal, and the bending force of a heavy load does the same. This is why people with higher muscle mass tend to have better bone density. Progressive overload matters. You have to keep challenging your body over time, not just maintain what you are already doing.

Vibration Plates

Vibration plate technology does show positive results for bone density, but with nuance. Not all vibration plates operate at the frequency range linked to bone benefits in research. If you have had any joint replacements, spine surgeries, or hardware implanted, get surgical clearance before using one and build back gradually.

Sleep and Stress

Bones do not build efficiently without sleep. Neither does muscle. If you are prioritizing supplements and exercise but running on poor sleep and chronic stress, you are working against yourself. The stress response has measurable negative effects on bone metabolism, and this is not soft advice, it is physiologically relevant.

Nutrition and Supplements for Bone Health

Protein first. Bones need protein just as much as muscles do, and most midlife women are under-eating it. Zora aims for 30 to 40 grams per meal across three meals a day.

Essential amino acids bridge the gap when whole food intake falls short. Both Zora and Natalie use Kion Aminos for this reason – to ensure all nine essential amino acids are present to support bone, muscle, and cellular repair.

Broad mineral support matters because bone metabolism depends on far more than just calcium. B Minerals is something both incorporate to cover that base, with the understanding that what you absorb matters as much as what you take.

AlgaeCal is a bone-centric supplement Zora has recently added. Rather than isolated calcium or a general mineral blend, it contains approximately 13 minerals specifically relevant to bone health plus the algae source itself has bone-supportive properties. Both Zora and Natalie are currently taking it and plan to retest.

Calcium from food, like cottage cheese, yogurt, leafy greens, remains one of the most bioavailable sources. Food first, supplements to fill gaps.

Test before you supplement. Zora’s strongest overall recommendation is to work with a functional medicine practitioner to identify actual deficiencies rather than guessing. If your gut is not absorbing nutrients well, even a thoughtful supplement routine may not deliver what you expect.

A Word on GLP-1s and Bone Loss

This area is early in research, but the concern is straightforward: if significantly reduced appetite leads to under-eating protein and key nutrients, bone building is compromised the same way any malnutrition affects it. If you are using a GLP-1, prioritizing protein intake and resistance training is not optional. It is essential.

The Fear Factor

There is a spectrum here. Some women truly do have fragile bones that require aggressive intervention. But many women are being grouped into the same fear bucket when their actual fracture risk is lower than a number on a scan suggests.

The goal is not to dismiss bone health, but quite the opposite. The goal is to be appropriately informed, not paralyzed. Fear drives stress, and chronic stress has measurable negative effects on bone metabolism. Getting stuck in anxiety about a number may actually work against the very thing you are trying to protect.

Get your baseline. Understand the full picture. Take the steps within your control. Do not let a single number define your trajectory.
