Nutrisense review: a pricey way to learn a little


Standing in my rest room, staring on the needle poking out of a steady glucose monitor (CGM), I began having second ideas.

CGMs measure glucose ranges in interstitial fluid — the fluid between your cells. In contrast to conventional fingerprick exams, they may give you real-time knowledge about your blood sugar ranges, they usually’re usually utilized by folks with Kind 1 diabetes to handle their situation. However Nutrisense and different firms like Levels and January are proposing that nondiabetics can use blood sugar knowledge to shed some pounds, optimize health positive aspects, and enhance their total metabolic well being. After all, these startups nonetheless have lots to show. When The Verge appeared into these units final yr, it was unclear whether or not CGMs had been efficient for folks with out diabetes, particularly when it got here to targets like weight reduction.

However I occur to be the type of person who firms like Nutrisense try to court docket. I don’t have diabetes, I eat effectively, and I train usually. Nevertheless, my household historical past and polycystic ovary syndrome (PCOS) analysis put me at a heightened danger of diabetes. My medical doctors say shedding weight will assist with the metabolic signs related to PCOS. Fueling correctly for races and exercises has all the time been a wrestle for me. On prime of real-time glucose monitoring, Nutrisense additionally pairs you with a dietician to make sense of your outcomes. On paper, the maths provides as much as me doubtlessly benefiting from CGM use — even when the proof isn’t absolutely there but.

In the end, I gritted my enamel and jammed a needle-bearing sensor into my arm.

How we fee and assessment merchandise

The way it works, setup, and elimination

As a result of CGMs require a prescription, it’s a must to take a questionnaire to see whether you’re eligible to make use of Nutrisense. If you’re, a Nutrisense physician will difficulty your prescription. After, you get despatched a package containing Abbott’s FreeStyle Libre CGM and two bandages. Individually, you obtain the Nutrisense app after which observe a collection of useful video tutorials that stroll you thru assembling the applicator and “putting in” the CGM sensor in your physique. When that’s performed, you slap the bandage over the CGM and hover your telephone close to the sensor to take your first measurement. It makes use of NFC, so it’s the identical movement as utilizing your telephone to pay for one thing on the retailer, simply on the again of your arm.

There’s a useful walkthrough within the Nutrisense app while you first get the CGM.

For the primary day, the sensor must be calibrated. Afterward, you’re inspired to log your meals and workouts so you possibly can immediately see how they affect your blood glucose ranges. The sensor solely retains about eight hours’ value of knowledge, so that you’ll should scan at the least thrice a day to make sure you don’t lose knowledge. (This may be annoying, and I did lose just a few hours right here and there.) After 14 days, you exchange the CGM and begin another time. For the primary month, Nutrisense offers you complimentary entry to a nutritionist who’ll assessment your knowledge, level out traits, and reply any questions you may need. (After that first month, it’ll price you $100 additional monthly.)

Not me nervously laughing whereas studying the instructrions.

I hate needles. For sure, I used to be a bit freaked out on the prospect of jamming this into the again of my arm.

That is straightforward to jot down out after the very fact, however I used to be sweatin’ throughout the complete setup course of. In contrast to a noninvasive system like Lumen, which claims to measure your metabolism by way of your breath, CGMs pierce your pores and skin with a small, skinny needle. The CGM Nutrisense makes use of is not any exception, and I hate needles the way in which Indiana Jones hates snakes. (I’m frankly unsure how I sat by means of three tattoos with out fainting.) It doesn’t assist that the applicator makes loud noises as you assemble it and incorporates a visual needle.

So I used to be shocked once I really felt nothing because the needle went in. The sound of the applicator was extra horrifying than the precise movement of jamming the applicator into my arm. Each the covid-19 jab and the flu shot are exponentially extra painful. That is probably since you insert the CGM into the fattiest a part of your underarm, whereas a vaccine goes straight into muscle.


Our photographer documented my complete emotional journey of carrying the CGM.

I used to be most nervous about inserting the CGM, however it was truly more durable to take away on the finish of my 14 days. There have been no official directions for this half, so I simply… pulled it off. What made it arduous was that the bandage Nutrisense offers you is kind of sturdy, and I had hassle ripping it off my pores and skin. Afterward, I had adhesive residue on my arm for 2 days although I scrubbed actual arduous within the bathe. You may as well see hint quantities of dried blood on the used CGM, and there was a small puncture mark on my arm. It healed inside a day, however Nutrisense recommends rotating arms to offer your pores and skin a few weeks to get well.

All about glucose

Utilizing Nutrisense is just like meals logging. You’re speculated to scan the sensor just a few instances a day and log all of your meals and train. Scanning brings up a squiggly line of your blood sugar ranges, and your meals / exercises are represented by purple dots on that line. Different components, like sleep, are proven as blue dots. Nutrisense interprets your knowledge in two buckets. First, there’s your glucose knowledge, and second, there’s your dietary knowledge. So that you can get essentially the most out of it, you actually do should be diligent about logging your meals.

I hate long-term meals monitoring. Whereas maintaining a tally of macros might be useful and insightful for coaching and weight reduction, no app I’ve ever examined does an excellent job of creating this handy. Nutrisense isn’t an exception, although it’s one of many higher implementations I’ve seen lately. On prime of looking a database or scanning barcodes like different calorie-tracking apps, you possibly can write out an outline or snap an image of your meal. Nutrisense’s AI will then populate your log with these gadgets. It’s not good — the AI will get elements fallacious, and also you’ll have to repair it manually. Nevertheless it offers you a beginning place. I used to be additionally impressed with the help for worldwide meals. I might log gimbap, tteokbokki, and Indian takeout with relative ease. That isn’t all the time the case.

Within the second shot, you possibly can see my glucose spike after a run the place I pushed myself.

Scanning and logging are the straightforward components. Deciphering the info, nevertheless, comes with a studying curve. For blood glucose, there’s the self-explanatory day by day common and a extra sophisticated Each day Glucose Rating. The latter includes your highest day by day glucose worth, common worth, adaptability (time spent above your glucose threshold), and variability (how intensely your glucose “swings”). I want that had been it, however there’s extra. Within the app’s Insights tab, you’ll discover different values, like how lengthy you spent throughout the perfect vary, variability, common, min, max, sleep common, and morning common.

Every metric is color-graded. Inexperienced is nice, orange is okay, and purple signifies areas of enchancment. In keeping with Nutrisense, you need to keep inside 70 to 140 milligrams per deciliter 95 to 100% of the time. You additionally need your variability to remain underneath 14mg/dL and in your morning and sleeping glucose averages to be between 70 and 105mg/dL.

In the meantime, every part you eat is given an total Meal Rating that’s made up of 4 metrics: peak, publicity, stability, and restoration. Peak is your highest glucose worth inside two hours of consuming; publicity is how sturdy your glucose response was; stability measures the best versus lowest values inside a two-hour consuming window; and restoration is how shut you get to your premeal ranges after two hours. Nutrisense makes use of the identical color-based grading system right here, too.

You simply maintain your telephone as much as the CGM to sync knowledge. Feels type of like contactless funds.

Nutrisense has a crap ton of academic materials throughout the app to elucidate all of this in additional element. I went by means of about two hours of it and barely scratched the floor. On the finish of the day, I relied primarily on the coloured grading scheme and would learn descriptions to remind myself what every submetric was and why it mattered.

In the end, I didn’t study a ton of latest issues about my blood sugar and consuming habits, however I appreciated having visible affirmation. I do know that I get cranky and sleepy if my blood sugar is low, however it’s vindicating to see the connection represented on a graph. I don’t want a CGM to inform me that tteokbokki — a dish that’s 90 p.c rice cake — will spike my glucose ranges, so I ought to in all probability have a protein together with it. It was extra attention-grabbing to see how the identical meal eaten at completely different instances of day might induce completely different responses. As an illustration, my nutritionist identified {that a} serving to of butter rooster curry produced a much less intense spike once I ate it for lunch versus a late-night dinner. Maybe essentially the most fascinating factor to me was how my glucose skyrocketed proper after a tough run — which is sensible as a result of your physique releases glycogen to gasoline that type of train. Conversely, a power coaching session registered as a comparatively flat line.

Nutrisense encourages experiments like these. That could possibly be numerous enjoyable! Particularly in case your data of dietary science might be summed up as “low-carb diets are in style for weight reduction.” However in the event you’re already acquainted with all of this, it’s much less thrilling. Extra of a “huh, would you take a look at that” than an “oh wow, that is blowing my thoughts!”

I’m smiling, however I’m actually considering, “Holy shitballs, it truly didn’t damage?!”

Living proof, my two weeks with Nutrisense indicated I used to be already doing every part proper — which was then confirmed by my nutritionist. My common glucose rating was 99. They informed me my baseline glucose traits had been effectively throughout the optimum vary of 70–90mg/dL, my highest spike by no means breached 140mg/dL, and I had “glorious glycemic variability” with a median of 11mg/dL. That was good to listen to contemplating I ate worse and exercised lower than traditional in these two weeks. Nonetheless, it was neat to have somebody interpret the info and be available to reply questions.

However the backside line was there wasn’t a lot for me to enhance. My glucose minimal was the one metric in orange as a result of I skipped just a few meals, and I had none within the purple zone. If I weren’t a reviewer, my two-week experiment would’ve price me a number of hundred {dollars} to study I’m already managing alright.

Accessibility is the most important difficulty

My largest downside with Nutrisense is that it takes a sure revenue degree simply to attempt it out.

My eyes practically popped out of their sockets just like the Tex Avery wolf once I noticed how a lot Nutrisense prices. It’s $399 for the no-commitment one-month plan, $299 month-to-month for the three-month plan, $250 month-to-month for the six-month plan, and $225 month-to-month for a 12-month plan. As talked about earlier, all plans get you a free month of nutritionist help, however you’ll should tack on $100 month-to-month after that. There’s no possibility for a free trial, and as soon as your plan ends, it’ll routinely renew on a month-to-month foundation except you pause or cancel. At a minimal, you’re $2,700 yearly on the 12-month plan or $3,800 in the event you shell out for the nutritionist help. Personally talking, I wouldn’t have been in a position to afford this expertise if I weren’t a reviewer — there’s no free trial for most individuals.

That’s a lotta moola, although the majority of the fee is the CGM itself. In keeping with Nutrisense’s FAQ page, the CGM it makes use of is not lined by any insurance coverage firms, although you need to use an HSA or FSA to assist with the fee. To be honest, different CGM startups are equally priced, however that merely underscores that, in the mean time, that is an extremely area of interest product.

Nutrisense’s CGM program could possibly be academic, however the value of entry is simply too steep for the typical particular person.

From my very own expertise as a wearables reviewer and somebody with PCOS, that’s so irritating. Behavioral change is tough, shedding weight is tough, and managing power circumstances is actually arduous. We gained’t have a greater concept if CGM applications like Nutrisense are efficient for nondiabetics in the event that they aren’t utilized by a wider inhabitants. However realistically talking, I don’t suppose the typical particular person would pay this a lot and scan a number of instances a day for a number of weeks or months with out at the least some expectation of capital-R outcomes. What’s extra probably is all that effort, time, and cash helps you study a bit bit extra about your self, and also you might see some outcomes over an prolonged timeframe. Even then, there’s no assure it offers you the answer you’re in search of. Is that definitely worth the value of entry?

If in case you have the means to attempt Nutrisense, I’m not going to cease you. Rising tech is, by definition, unproven, however typically you simply don’t query why one thing works for you. I firmly imagine it’s your proper to determine what that factor is. However as with Lumen, I might say it is best to go in with tempered expectations. I hoped to seek out out one thing I didn’t already know or had ignored. What I obtained was an underwhelming however sobering reminder that there’s no magic bullet for power circumstances.
