For those who’re into biohacking or customized vitamin — and even in case you’re not — you’ve in all probability heard about steady glucose displays (CGMs). These wafer-thin disks stick with the again of your arm, with a tiny wire inserted slightly below the pores and skin to measure blood-sugar ranges. They ship minute-by-minute measurements to an app in your cellphone, which then sounds an alarm in case your blood sugar spikes or dips.
CGMs could 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 additionally to the intervals at which we feed ourselves, and the influence that bodily exercise and stress have on blood glucose,” says useful nutritionist Jesse Haas, MS, CNS, LN.
Whenever you see and really feel how a plate of pasta or a superb 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 additionally, it wasn’t.
I grew up in a household that liked meals, particularly carbs, and toast particularly. 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 residence I’ve lengthy maintained a strong Mediterranean weight-reduction plan, and I used to be a runner for years; for a time these wholesome habits have been sufficient to maintain the consequences of my eating life in verify.
Then the day arrived once I received a notice from my doctor about my current A1C blood check: It confirmed my common blood-sugar degree within the prediabetic vary. I wanted to make some way of life adjustments, so I began utilizing a CGM to assist me determine which shifts made a useful influence and which didn’t.
This labored effectively for me, however metabolic well being is complicated, and completely different our bodies want completely different interventions. So, when contemplating whether or not to speculate time, power, and cash right into a CGM, it’s price pausing to be sure you really want one. These are some things I realized from utilizing mine.

You might not know you will have dysregulated blood sugar.
The Facilities for Illness Management and Prevention (CDC) estimates that a couple of in three adults have prediabetes — and that greater than eight out of 10 don’t understand it. In keeping with Rita Rastogi Kalyani, MD, MHS, president-elect of drugs 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 regularly as really helpful. Even when they’re, physicians don’t at all times 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 have been good.
A couple of in three adults have prediabetes — and that greater than eight out of 10 don’t understand it.
But prediabetes could be critical. Not solely does it enhance the probability of growing sort 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 elements for growing sort 2 diabetes, in line with Kalyani, are being larger 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 elements.
Ladies who’ve had gestational diabetes or have polycystic ovary syndrome are additionally at larger threat. The ADA recommends common diabetes screenings in case you’re over 35 whether or not you will have any of those traits or not.
Due to my Asian American and Pacific Islander heritage, I’m not solely genetically predisposed to develop sort 2 diabetes but additionally liable to growing it even with a decrease body-mass index (BMI). The overall rule is that diabetes threat will increase at a BMI of 25 — however each the ADA and the CDC acknowledge that Asian People ought to display at a BMI of 23. (It’s essential 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) could 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 likely 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 weight-reduction plan 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 wish to be a human doing human life.”

A CGM might help you keep motivated.
A examine from the CDC’s Nationwide Diabetes Prevention Program exhibits that way of life adjustments are about twice as profitable as medicines at decreasing the danger of diabetes. Dropping just a little weight, altering your weight-reduction plan, and exercising frequently can all assist the physique regulate blood glucose. The truth is, the examine discovered that these adjustments can reduce your diabetes threat in half.
My doctor suggested I get a minimal of 150 minutes of cardio exercise per week; lose 5 to 7 % of my physique weight; eat fewer easy carbohydrates; and eat a weight-reduction plan 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. Once I did, my A1C improved, however quickly the need for sugar crept again. I reverted to outdated consuming habits, and after three months my A1C was again to five.9 %.
Way of life adjustments are about twice as profitable as medicines at decreasing the danger of diabetes.
“A1C lab checks could be run at 90-day intervals to watch blood-glucose averages, however a check-in each 90 days affords little accountability,” says Haas. “For people who find themselves actually enthusiastic about making a behavioral change, a CGM offers us real-time knowledge.”
This inside suggestions can be a fantastic supply of “inspiration, motivation, and accountability,” she provides. The CGM reveals exact details about how particular decisions have an effect on your physique, which might help you fine-tune the extra normal recommendation you may get out of your doctor or nutritionist.
Health and vitamin educator Mike T. Nelson, PhD, MSME, CSCS, CISSN, has given lots of thought to CGMs and motivation. He says it may be arduous to persuade the athletes he works with that they’ve dysregulated blood sugar. They is probably not feeling optimum, however when their way of life, sleep, and vitamin 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 occurring,’” he says.
That was true for me. I couldn’t change my habits till I went to see an endocrinologist and received a prescription for a CGM, which offered me with real-time suggestions on how my decisions have 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 in case you hope to get one coated by insurance coverage (although not all insurance policy cowl them). I used to be capable of get two CGM sensors, a month’s price, for a $75 copay. (If I hadn’t had insurance coverage, the price would have been double.)
Till lately it was robust to get a CGM and not using a prescription, however that’s altering. A rising variety of digital well being corporations, like Nutrisense, Ranges, and Zoe, are pairing CGMs with cellphone apps to watch blood-glucose ranges, observe vitamins, and provide customized dietary suggestions. As well as, Dexcom and Abbott, two of the first CGM producers in the US, lately gained FDA approval to launch over-the-counter variations of their glucose displays.

For greatest outcomes, accomplice with knowledgeable and set objectives.
Nelson suggests setting parameters in your CGM use. The primary is to you should definitely work with a well being skilled. This might 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 persons are attempting to do their greatest, they’ll simply get hung up on a quantity — a quantity that’s not at all times good or at all times unhealthy.”
The second parameter: Know your objectives. “Work out what you wish to be taught from this knowledge forward of time,” advises Nelson. “You want a speculation and a few experiments so to be taught from it.”
Know your objectives. “Work out what you wish to be taught from this knowledge forward of time.”
The preliminary revelations from my very own CGM allowed me — with assist from my endocrinologist — to know tips on how to start decreasing 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 deal with the subtler questions, like, Why am I having low blood sugar within the morning? Can I’ve some grains in my weight-reduction plan? What ought to I do if I’m experiencing excessive blood sugar over a long run? I’d have been fairly misplaced with out this steerage.
The third parameter Nelson suggests: Be prepared to alter. As soon as you identify how you should regulate your weight-reduction plan and way of life, 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 people who’re inclined to get extra anxious once they’re getting lots of enter,” Haas explains.
She suggests anybody with disordered consuming could wish to avoid 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 provoke individuals to make sweeping vitamin choices — even when every little thing 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. Individuals 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 occurring in your physique.
Metabolic well being influences all of the physique’s techniques, so blood-sugar regulation has a broad influence on well-being. These are just some examples of what blood-sugar measurements can reveal.
• Stress: After we’re nervous, triggered, or in a annoying scenario, the physique releases cortisol, which raises blood glucose, Haas explains.
• Sleep: There are a lot of potential causes for poor sleep, and a CGM can reveal if blood sugar is what’s maintaining you awake. Our physique’s pure circadian rhythms increase blood-sugar ranges at evening, 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 can even disrupt your blood sugar.”
• Weight administration: A CGM can present how completely different meals have an effect on our blood sugar. This suggestions might help us regulate our weight-reduction plan in favor of larger 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 will additionally present you the constructive influence of a postmeal stroll in actual time.

Except you will have diabetes, a CGM is a spot to go to, to not dwell.
Specialists agree that for most individuals who don’t have diabetes, a CGM is greatest used as a short-term intervention. Nelson recommends sporting a CGM for 2 weeks to determine 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 info 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 can be actually going to maneuver the needle.”
Haas goals for 3 months with a CGM to determine a baseline. “Ninety days is sufficient time to concentrate on just about something — and to actually create a brand new behavior.”
Past that, she suggests utilizing the CGM for brief intervals a few occasions a yr to assist behavior upkeep. A CGM can be helpful anytime you’re present process a notable transition, equivalent to perimenopause, throughout which the physique’s wants are more likely to change.
“[It’s good for] any huge life change the place stress is excessive and relearning self-care is actually important,” she advises.

A CGM may give 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 realized 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 every little thing goes higher if I load up on protein and fiber; I want a small snack earlier than mattress; and, wow, does public talking give me a spike — regardless that I form of dig speaking to a crowd.
Most significantly, the CGM plus some wonderful healthcare recommendation helped me determine tips on how to preserve my blood sugar pretty balanced — and I received my A1C down to five.4 %. My endocrinologist tells me that if I preserve it down, I’m much less more likely to develop sort 2 diabetes. That’s life-changing drugs.
“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 lots of different measurements within the physique that you may push round that a lot. And you’ll see a reasonably large change, generally briefly order.”
