In the event you’re into biohacking or customized diet — and even when you’re not — you’ve in all probability heard about steady glucose displays (CGMs). These wafer-thin disks keep on with the again of your arm, with a tiny wire inserted just under the pores and skin to measure blood-sugar ranges. They ship minute-by-minute measurements to an app in your telephone, which then sounds an alarm in case your blood sugar spikes or dips.
CGMs may be helpful for anybody who struggles with blood-sugar administration — or who wonders whether or not they do. “We are able to use CGMs to get a bunch of knowledge about how the physique responds not simply to how we eat but in addition to the intervals at which we feed ourselves, and the affect that bodily exercise and stress have on blood glucose,” says practical nutritionist Jesse Haas, MS, CNS, LN.
Whenever you see and really feel how a plate of pasta or a great morning exercise have an effect on your blood sugar, she provides, you can begin to attach this info to different alerts out of your physique. “That may be actually empowering.”
Because it occurs, Haas is my nutritionist. I sought her out after discovering I had excessive blood sugar. That was a shock — but in addition, it wasn’t.
I grew up in a household that beloved meals, particularly carbs, and toast specifically. At household breakfasts, my grandfather stored a four-slot toaster and a loaf of nation white on a bar cart at his elbow. Upon request, he’d ship slices of piping scorching toast flying down the desk. (You need that butter to soften!)
As an grownup, my skilled life has revolved round writing about meals. At house I’ve lengthy maintained a stable Mediterranean eating regimen, and I used to be a runner for years; for a time these wholesome habits had been sufficient to maintain the results of my eating life in test.
Then the day arrived once I acquired a observe from my doctor about my current A1C blood check: It confirmed my common blood-sugar stage within the prediabetic vary. I wanted to make some life-style adjustments, so I began utilizing a CGM to assist me establish which shifts made a useful affect and which didn’t.
This labored effectively for me, however metabolic well being is complicated, and totally different our bodies want totally different interventions. So, when contemplating whether or not to speculate time, vitality, and cash right into a CGM, it’s value pausing to be sure to really want one. These are some things I discovered from utilizing mine.

Chances are you’ll not know you might have dysregulated blood sugar.
The Facilities for Illness Management and Prevention (CDC) estimates that multiple in three adults have prediabetes — and that greater than eight out of 10 don’t realize it. In line with Rita Rastogi Kalyani, MD, MHS, president-elect of medication and science for the American Diabetes Affiliation (ADA), there could also be many causes for this, together with that most individuals in all probability aren’t getting a fasting glucose or A1C check frequently as really helpful. Even when they’re, physicians don’t all the time flag a prediabetic quantity.
The blood-sugar vary for prediabetes is 5.7 to six.4 %; diabetes is 6.5 % or above. I had been hovering at 5.9 %, however my very own doctor hadn’t talked about it, probably as a result of my different well being markers had been good.
Multiple in three adults have prediabetes — and that greater than eight out of 10 don’t realize it.
But prediabetes may be critical. Not solely does it enhance the chance of growing kind 2 diabetes however the situation additionally raises the danger of coronary heart illness, stroke, and nerve harm. Diabetes itself can result in extra main problems, together with kidney failure and blindness.
Among the many threat components for growing kind 2 diabetes, in accordance with Kalyani, are being increased weight, having a household historical past of the illness, and being in a high-risk group — African American, Latino, Native American, Asian American, or Pacific Islander. Hypertension and dyslipidemia (a metabolic dysfunction involving abnormally excessive or low ranges of lipids within the blood) are different potential threat components.
Ladies who’ve had gestational diabetes or have polycystic ovary syndrome are additionally at increased threat. The ADA recommends common diabetes screenings when you’re over 35 whether or not you might have any of those traits or not.
Due to my Asian American and Pacific Islander heritage, I’m not solely genetically predisposed to develop kind 2 diabetes but in addition prone to growing it even with a decrease body-mass index (BMI). The final rule is that diabetes threat will increase at a BMI of 25 — however each the ADA and the CDC acknowledge that Asian Individuals ought to display at a BMI of 23. (It’s necessary to notice that BMI itself is an unreliable measurement of physique composition and well being, which can be another excuse to easily get screened it doesn’t matter what.)
The indicators of dysregulated blood sugar (additionally referred to as dysglycemia) may be refined. I usually felt cranky or bodily shaky between meals and drained after meals, however I assumed everybody did.
“The signs of dysglycemia are sneaky,” says Haas. “We don’t take into consideration issue concentrating or making choices as signs of low blood sugar. And we are inclined to affiliate the extra cognitive, emotional, and psychological signs — like anxiousness, irritability, or melancholy — with one thing apart from biochemistry, however that’s part of it too.”
She provides that the restrictive consuming patterns lauded by eating regimen tradition have additionally helped normalize the signs of low blood sugar. “This units us as much as have a extremely distorted expectation of what it feels prefer to be a human doing human life.”

A CGM may help you keep motivated.
A research from the CDC’s Nationwide Diabetes Prevention Program reveals that life-style adjustments are about twice as profitable as medicines at reducing the danger of diabetes. Dropping a bit of weight, altering your eating regimen, and exercising commonly can all assist the physique regulate blood glucose. In reality, the research discovered that these adjustments can reduce your diabetes threat in half.
My doctor suggested I get a minimal of 150 minutes of cardio exercise every week; lose 5 to 7 % of my physique weight; devour fewer easy carbohydrates; and eat a eating regimen wealthy in greens and fruits, fiber, and wholesome fat, like avocado, nuts and seeds, olive oil, and fish.
I used to be already doing most of that, although I did want to chop again on the cake and toast. After I did, my A1C improved, however quickly the need for sugar crept again. I reverted to previous consuming habits, and after three months my A1C was again to five.9 %.
Life-style adjustments are about twice as profitable as medicines at reducing the danger of diabetes.
“A1C lab checks may be run at 90-day intervals to observe blood-glucose averages, however a check-in each 90 days provides little accountability,” says Haas. “For people who find themselves actually thinking about making a behavioral change, a CGM offers us real-time knowledge.”
This inside suggestions will also be an ideal supply of “inspiration, motivation, and accountability,” she provides. The CGM reveals exact details about how particular decisions have an effect on your physique, which may help you fine-tune the extra common recommendation you would possibly get out of your doctor or nutritionist.
Health and diet educator Mike T. Nelson, PhD, MSME, CSCS, CISSN, has given loads of thought to CGMs and motivation. He says it may be exhausting to persuade the athletes he works with that they’ve dysregulated blood sugar. They is probably not feeling optimum, however when their life-style, sleep, and diet habits are all fairly good, they’re usually satisfied there’s no want for change.
“There’s one thing about precise knowledge, seeing their blood-glucose numbers — then they’re like, ‘Oh, there is one thing happening,’” he says.
That was true for me. I couldn’t change my habits till I went to see an endocrinologist and acquired a prescription for a CGM, which supplied me with real-time suggestions on how my decisions had been affecting my physique.

Getting a CGM is turning into simpler.
CGMs are nonetheless used primarily by individuals with diabetes, and also you want a prescription when you hope to get one coated by insurance coverage (although not all insurance coverage cowl them). I used to be capable of get two CGM sensors, a month’s value, for a $75 copay. (If I hadn’t had insurance coverage, the fee would have been double.)
Till not too long ago it was robust to get a CGM with out a prescription, however that’s altering. A rising variety of digital well being corporations, like Nutrisense, Ranges, and Zoe, are pairing CGMs with telephone apps to observe blood-glucose ranges, monitor vitamins, and provide customized dietary suggestions. As well as, Dexcom and Abbott, two of the first CGM producers in america, not too long ago gained FDA approval to launch over-the-counter variations of their glucose displays.

For finest outcomes, associate with an expert and set targets.
Nelson suggests setting parameters in your CGM use. The primary is to you should definitely work with a well being skilled. This may help you place the suggestions you get into a bigger context. “You want somebody that will help you determine it out,” he says. “Even when individuals are attempting to do their finest, they’ll simply get hung up on a quantity — a quantity that’s not all the time good or all the time dangerous.”
The second parameter: Know your targets. “Work out what you wish to study from this knowledge forward of time,” advises Nelson. “You want a speculation and a few experiments to be able to study from it.”
Know your targets. “Work out what you wish to study from this knowledge forward of time.”
The preliminary revelations from my very own CGM allowed me — with assist from my endocrinologist — to know methods to start reducing my A1C: Reduce down on easy carbohydrates; enhance the fiber, fats, and protein in my meals; and get extra common train.
Then I began working with Haas for dietary fine-tuning. She helped me handle the subtler questions, like, Why am I having low blood sugar within the morning? Can I’ve some grains in my eating regimen? What ought to I do if I’m experiencing excessive blood sugar over a long term? I’d have been fairly misplaced with out this steerage.
The third parameter Nelson suggests: Be prepared to alter. As soon as you determine how that you must regulate your eating regimen and life-style, be able to do it. Your partnership with a well being skilled can present accountability.

CGMs can stoke anxiousness.
Whereas a few of us discover the real-time suggestions of a CGM motivating in a wholesome approach, that’s not true for everybody. “There’s a warning for folk who’re inclined to get extra anxious after they’re getting loads of enter,” Haas explains.
She suggests anybody with disordered consuming might wish to keep away from a CGM, particularly these inclined to excessive meals restriction. “It’s not all good, proper?” she provides. “That’s a part of customized healthcare — reflecting and self-selecting.”
Nervousness round blood-glucose numbers may additionally provoke individuals to make sweeping diet choices — even when the whole lot else is okay. Nelson has watched purchasers undertake a ketogenic protocol after seeing borderline excessive blood sugar on their CGM, which might simply find yourself being an overcorrection.
“I get nervous when individuals take knowledge out of context,” he says. “It occurs with heart-rate variability, it occurs with sleep knowledge, it occurs with a CGM. Persons are so into optimizing that they’re worrying about stuff they only shouldn’t be nervous about.”

Monitoring your blood sugar can train you numerous about what’s happening in your physique.
Metabolic well being influences all of the physique’s programs, so blood-sugar regulation has a broad affect on well-being. These are only a few examples of what blood-sugar measurements can reveal.
• Stress: Once we’re nervous, triggered, or in a worrying state of affairs, the physique releases cortisol, which raises blood glucose, Haas explains.
• Sleep: There are lots of potential causes for poor sleep, and a CGM can reveal if blood sugar is what’s conserving you awake. Our physique’s pure circadian rhythms elevate blood-sugar ranges at night time, a surge referred to as the daybreak impact. For individuals with dysglycemia, this surge tends to have an effect on sleep high quality.
The reverse can be true. “It’s not simply that dysglycemia disrupts sleep,” says Haas. “Poor sleep also can disrupt your blood sugar.”
• Weight administration: A CGM can present how totally different meals have an effect on our blood sugar. This suggestions may help us regulate our eating regimen in favor of higher blood-sugar regulation. “We’re telling our pancreas, ‘Hey, we’re good. We’re going to cut back the glucose burden so that you simply’re not exhausted pumping out insulin.’ And that’s going to assist weight steadiness,” Haas explains.
• Train and athletic efficiency: CGMs can present us how train impacts our blood sugar, together with how shortly we’re recovering from strenuous exercises. They’ll additionally present you the optimistic affect of a postmeal stroll in actual time.

Except you might have diabetes, a CGM is a spot to go to, to not stay.
Consultants agree that for most individuals who don’t have diabetes, a CGM is finest used as a short-term intervention. Nelson recommends sporting a CGM for 2 weeks to ascertain a baseline. He believes it’s paramount to keep away from knowledge overwhelm, and counsels his health purchasers not to have a look at their knowledge for the primary week. He does this to stop them from making dramatic adjustments on their very own with out his enter.
After reviewing the information from the primary week, Nelson and his purchasers determine on three or 4 areas of focus for the following spherical. “By the tip of two weeks, they’ve some actionable knowledge and a pair issues that we’ve discovered which might be actually going to maneuver the needle.”
Haas goals for 3 months with a CGM to ascertain a baseline. “Ninety days is sufficient time to concentrate on just about something — and to essentially create a brand new behavior.”
Past that, she suggests utilizing the CGM for brief durations a few instances a 12 months to assist behavior upkeep. A CGM will also be helpful anytime you’re present process a notable transition, corresponding to perimenopause, throughout which the physique’s wants are prone to change.
“[It’s good for] any huge life change the place stress is excessive and relearning self-care is admittedly essential,” she advises.

A CGM can provide you a greater understanding of what your physique wants.
For me, the CGM was the equal of a front-row seat on the carb-tolerance present: I discovered that rutabagas don’t work for me however lentils do. That I can eat brown rice if it’s had an evening within the fridge growing resistant starches. Not so with candy potatoes: Even a wee dollop is an issue.
There have been different nice classes, too, like the whole lot goes higher if I load up on protein and fiber; I would like a small snack earlier than mattress; and, wow, does public talking give me a spike — although I form of dig speaking to a crowd.
Most significantly, the CGM plus some glorious healthcare recommendation helped me determine methods to preserve my blood sugar pretty balanced — and I acquired my A1C down to five.4 %. My endocrinologist tells me that if I preserve it down, I’m much less prone to develop kind 2 diabetes. That’s life-changing medication.
“That’s the attractive factor a few CGM,” says Nelson. “You can also make large adjustments to your knowledge with easy interventions. There aren’t loads of different measurements within the physique that you may push round that a lot. And you’ll see a reasonably large change, typically briefly order.”
