About three years ago, my doctor told me that I needed to lose belly fat. They didn’t care about my belly fat. This, he said while pinching me, was subcutaneous fat. What he wanted was for me to lose about five pounds of fat above my belly because that’s where the visceral fat is. Not to lose weight; My BMI and weight, they said, were fine. I needed it oil loss because I had borderline high cholesterol and one mildly elevated liver enzyme. Considering polycystic ovary syndrome (now known as polyendocrine metabolic ovarian syndrome), believed that type 2 diabetes was lurking in my face unless I quickly changed my body condition.

She told me to spend wisely – and commit to a healthy diet. I ignored the latter (and, after a few months, I changed after the doctors presented a questionable podcast). But I started playing more seriously with the scales of wisdom, and began a years-long journey of depression.

Smart scales use a technique called bioelectric impedance analysis (BIA) to give you a breakdown of your body fat, lean tissue, and bone mass. (Some advanced scales include other metrics, but it depends on the device.) The basic principle is that a weak electrical current is sent through your body. Fat, muscle, and other types of muscle all have different reactions, so based on the measured resistance, the algorithm then calculates how much of each you have. They are more accessible to consumers than other medical methods, but they can be very inaccurate. It is easy to have two BIA scales and get very different results.

For example, this morning I stepped on three smart scales: two from Withings (one only measures your feet; the other has body mass analysis), and the third from a company called Twin Health. When I go to my doctor for my monthly follow-up, I get weighed with an InBody scale, which is a smart version of the smart scales that people have at home. Two weeks ago, I went to the sports clinic to get my first Dual-Energy X-ray Absorptiometry (DEXA) scan, which shoots high-energy X-rays through your body to give a breakdown of your body, including bone density. It is often considered the “gold standard” in the medical field. None of these products have ever given me a single drop of body fat.

Instead, here are the latest stats for each level:

Of course, I wasn’t able to take all of these measurements in one day, so variations are to be expected. However, they were all taken within two weeks of each other, after fasting, and first thing in the morning. All these tools claim to be accurate. Withings says its BodyFit scale technology — which includes a retractable handle and eight electrodes — conducted an internal clinical audit of 80 participants and found a 99 percent correlation with DEXA scans. Let’s say the DEXA scan is very accurate. I’m looking for a difference of 5 to 12 percent between it and other materials. My highest and lowest readings differ by 17 percent. They are a very much difference.

And that’s just one metric. My metrics for lean mass (whatever but fat) are very different. DEXA, the Withings BodyFit, and InBody analyze your body by body parts, such as the torso, legs, and arms. Those readings also it varies from 5 to 8 percent. Some even compare bone density to visceral fat. Can you believe my measurements have a big difference there too?

For example, a DEXA scan says that I have very strong bones and that my bones make up about 4.1 percent of my total body weight. Withings says 3.7 percent. On a scale of 1 to 20, the two Withings scales estimate my visceral fat at 1.9 and 2.1, respectively. (1 to 12 is good, 13 to 20 is high risk.) InBody estimates at 14. My DEXA scan says I have 1.24 pounds of visceral fat and that, of course, I can get that number down to a pound or less.

Am I okay? Honestly, it depends on who you ask. I’m sure those who exercise a lot would say I’m fat and need to be locked in and molded. DEXA and InBody both gave me a C-grade on my body composition. Ten years ago, I probably would have been more concerned about health and trying to find out which devices were “more accurate” and “more accurate”.

The real truth is, it doesn’t matter.

I have no long term results of DEXA. Those scans are expensive (from $75 to $300 a pop), and in most cases, it’s recommended that you only take it every three to six months. But the photo is something I did to prove a point: the accuracy of these tools is not as important as it was. consistency. DEXA scans are very accurate, with a clinical margin of error of about 1 to 2 percent — but it also depends on the location, machine control, and fluid level. The first DEXA scan calculates your location. Subsequent scans are where you start to see more useful information as you progress. It’s true regardless the bodybuilding method of your choice – whether it’s a cheap test or the cheapest one you found in a Prime Day sale. As long as each method is “incorrect” at almost the same time of error each time, the most useful data they provide is your long-term experience.

Again, none of these tools ever wrote the same numbers for me. Even something as simple as my weight can vary by one or three-tenths of a pound, all the other factors that are controlled. But what they all he said doing and telling the whole story I love. Body fat and visceral fat decrease in the same way by a large amount. Weight loss remains flat or increases slightly. In methods that measure skeletal muscle, it decreased slightly. My bone density has not changed. Overall, these are signs that my treatment plan is working and point to the same mindset: prioritize rebuilding lost muscle, continue to monitor side effects, review my blood tests quarterly, and continue until the doctor is happy with where I am.

This concept also applies to other wearables, such as smart watches and basic fitness trackers. The daily numbers don’t mean as much as your weekly and monthly numbers. If you want to move more, it doesn’t matter if your Apple Watch says you took 9,000 steps and Whoop says you took 8,000. Worrying about what is “right” misses the whole point. The important thing is that any tracker you choose measures the same distance as the same number of steps (or GPS distance) every time.

There are nuances to this. I started getting a physical exam three years ago because the doctor scared the bejeezus out of me. Since then, I have tried about eight different scales and body-based technologies of various intelligences. Until my DEXA scan, I never had reliable information on my body fat percentage. I don’t do that. Here’s what I know: My body didn’t adapt to traditional activities. As a result, I have insulin. That makes it it is easier to store fat, which increases insulin resistance. I have never learned this from any BIA tool! Fixing on any metric – whether it’s clothing, a scale, or a blood test – has not been the key to unlocking my metabolic syndrome. I never prepared myself to get out of the lucky instincts.

Healthy and fit, I feel great. I have also had a serious problem. All my numbers right now paint a very mixed picture. I can get lost in the grass if I’m not careful. But what’s going on? I’m on a better path than I’ve ever been, and that’s the most important thing.
