Stelo Glucose Biosensor & App - 2-Pack (Up to 15 Days Each). iOS & Android

I’m in the 50+ range and my lab tests were generally normal, as of lately with slightly elevated fasting glucose. Until I developed an early cataract and my eye doctor asked me if I was diabetic. What!? I decided to get the Dexcom Stelo because the reports are more aligned with what a doctor would want to see.I put the 1st sensor where it is recommended, the back of my arm. Then I went on to have breakfast. ham and cheese omelet, ½ a bagel with cream cheese and a glass of orange juice. And then my world came crumbling down. My glucose was already high, 120 and after 40 minutes it shot up to 240!!!! I was lucky I had the chance to hop on a treadmill and I walked that off until I saw 80. About 40 minutes.From that point my world had completely changed. My insulin is not performing as it should, hence the cataract and other health issues.I then began a quest to keep that glucose stable and I have to say, now 45 days into this project I lost 10lbs (from 180 to 170) just by monitoring what I eat and walking more. I still eat pizza and chocolates, but not to the rate I used to and thanks to the CGM I now know when to stop or mitigate a spike.Is it perfect? Absolutely not. Is it accurate? Not really. But it gives you an important view of what is happening in your body, glucose related.Does it hurt? No, but sometimes it is uncomfortable. Well there is a needle in your skin and as you can see from the images a fairly big one. yeah, yeah, it is made of soft whatever, but it is a needle. So if you bump on the sensor, put pressure on it or anything that may move that needle inside you skin you will feel something. It is not pain, oh my god let me rip this out of my body, but you do feel something.PLACEMENT - VERY IMPORTANTThe first one as I mentioned was on the back of my left arm. This location gave me steady almost uninterrupted readings. But I’m a side sleeper and I worried (for 14 nights) that I could be sleeping on top of the sensor. So the 2nd sensor I decided to move a bit inwards my arm. I carefully selected a region between my biceps and triceps muscles. From reading other reviews, sticking it on a muscle is a big no no, so I did not want to try that.That place I would not sleep on top of it, but I did not account for walking. And as my arm moved back and forward the sensor was being hit. And of course I went to a Disney park and walked 20,000 steps (no exaggeration here) daily. So the second sensor did bother me a bit. I felt some pain at times and it began "timing out” a lot. Still negligible for what I need but there were many, many times the sensor did not record a reading. You see gaps in the dots.The third sensor I decided to, as instructed by internet knowledge, put it on a fatty place so I chose the lower center of my belly fat, right below my belly button. And I learned two very important things.One - the first 6 hrs your readings will be high, much higher than normal. I noticed that with my 2nd sensor and confirmed it with my 3rd. The reason being is that your body is reacting to a foreign object so it is sending “healing” power to the region. Apparently glucose is part of the healing process. I don’t know the biology behind it but a quick research online and with AI, yeah it does happen. Some people even put a new sensor 12 hrs before activating it to get consistent readings.Two - reading from my belly fat is incredibly inconsistent. First I thought there is a sensor issue because after a meal it shoots up to 170 in 20 minutes, then comes crashing down, then up, then down. Like a roller coaster. Readings from the back of my arm were much more consistent. Going up to 140 at most, and slowly coming down. So again, I’m not a doctor or a bio whatever expert, but a quick research shows that this does happen. And it sort of makes sense. I have 0 fat on the back of my arm but some noticeable fat on my belly. Now I have the proof of why. For whatever reason the human body circulates more glucose on fatty areas than on lean ones. Hence why you have stored fat!!! Makes sense, no?At any rate I’m still trying to understand the whole placement and readings, but my next sensor will go back to the back of my arm for sure.The ProsIncredible Metabolic Insight: This device completely takes the guesswork out of nutrition. I learned very quickly that my body reacts to "healthy" foods (like fruit) with significant glucose spikes. It taught me that I don't necessarily have to cut foods out entirely, but rather manage my portions to keep my levels stable.The App Experience: The software is intuitive and makes the data easy to digest. Watching the real-time difference between a high-carb meal and a keto-friendly meal is a masterclass in how your specific metabolism works. The last update now uses AI to look at a picture of your food and then give you an estimated breakdown of Carbs, Fiber, Protein and fat as well as calories. You can also scan a barcode and it will tell you exactly what the food you are consuming is (if it was made in America - no international barcode yet). So for a diet perspective it is an invaluable tool to correlate a particular food combination with your glucose.Clever Application: The applicator is well-designed for those of us who are squeamish. It’s a "push-button" system that applies the sensor instantly. You don't even see the needle/filament until you take the device off days later, which is a huge plus if you have a phobia of needles.Reports: The reports are invaluable. Very detailed and almost medical grade data. They are also interactive when viewing with your browser. You can mouse over a specific reading and it shows what the reading number is. Very insightful especially for night readings. I used to have the Somogyi effect (glucose crashes at 2am then rises high to compensate and you wake up at 120), and now it's almost under control. No more night sweats, waking up thirst, yada, yada, yada.The ConsPhysical Discomfort: While the application is "painless" in the moment, the wearability can be hit-or-miss. I experienced some itchiness and sensitivity in my arm throughout the week.Placement is Critical: If you don't get it in the "sweet spot," it can be uncomfortable. I felt some random pains and had trouble sleeping on that side. I even had to cut a tricep workout short because it felt like the filament was agitating the muscle or a nerve.DIY Medical Hurdles: Since this is a one-size-fits-all applicator for a medical-grade device, there is a small margin for error. If it doesn't sit perfectly under the skin, you’re going to feel it for the duration of the wear.Accuracy "Mood Swings": This is the biggest sticking point. While some sensors are spot-on, others can be 30–60 points off compared to a finger-prick test. It’s better for seeing trends (spikes and dips) than for trusting the exact number to the digit. But this also may be a placement issue. Hard to say.Support: This is a DIY thing. Do not expect anyone to help you on the phone even if you have a defective sensor.Overall SummaryThis biosensor is a 5-star tool for data, but a 4-star experience for comfort. If you are following a specific health protocol (like the Frank Suárez "Metabolism" principles) or trying to optimize your weight lifting and diet, the information you gain is invaluable. It transforms your body from a "black box" into a readable map, showing you exactly how much glucose your body tolerates at any given time.And by understanding your specific metabolism you can control your diet and exercise to dial your glucose to a healthy pattern hence increasing your health and lifespan.Recommendation: BUY, especially if you are serious about fitness or metabolic health. Just be very mindful of your placement during application to ensure it doesn't interfere with your sleep or workouts!

If I could give it less than 1 star I would. Sensor worked for only 8 days, and then gave me a “Signal Loss” message. I went through all the trouble shooting steps in the app, and checked all my phone settings. Signal NEVER came back. App says if signal loss lasts longer than 3 hours, contact customer service. I went through the app to manufacturer’s website. Customer service is an automated chatbot called SteloBot. Eventually, I was able to request chat with a live agent in the Philippines, which is also where their technical “support” is. The agent said they would request a Case ID be assigned and open an investigation, and that I would hear back in 1-2 business days. The next day, which was Saturday, I received an e-mail with a case ID number, and a link to fill out the customer service form. There was space to provide details of what the issue was as well as the sensor serial #. Before I could submit the form on Sunday, I received another e-mail saying that if I didn’t respond within 24 hours, they would consider the case closed. I submitted the form. The Stelo/DEXCOM system, acknowledged receipt of the form, and again said I would hear back in 1-2 business days. 8 days later I still had not heard back, so I again went through the Customer Service rig-a-marole, to finally contact a live agent. They were polite and apologetic,and they requested a “reinvestigation” . I received an e-mail later that day saying, my “customer service issue could not be validated” (whatever the hell that means), and that they would not replace the faulty sensor. I contacted customer service AGAIN, and asked what “could not be validated” meant. I was told the “computer investigation” said the signal came back after 10 mins. I told the agent that was not correct. The app said “Signal Loss” and the signal NEVER came back. I checked multiple times a day for the remaining time the sensor was supposed to be working. Never came back. I asked if there was anyway they could just replace the sensor anyway, and was told that it was not possible for her to override the computer’s decision. I told her once again that the “computer investigation” was incorrect, and that there was no communication between the sensor and the app on my phone, after the initial signal loss and that the signal never came back. I was told that they could not manually issue a request to replace the sensor. For what it’s worth, there also seemed to be no mechanism to attempt to re-pair the sensor with my phone, or the app installed on my phone. While it was working, the app/sensor worked okay. Be aware, the sensor DOES NOT measure actual blood glucose. It measures the amount of glucose in your interstitial fluid in your tissues, just beneath your skin. If you’re diabetic and/or need your exact blood glucose, this is NOT the device for you. I’m almost 70. Blood glucose was not diabetic level, but was higher than my doc would have liked on my last 2 physicals. My wife is an RN, and thought these might be a good indicator of what affected my blood glucose and by how much. The accuracy is roughly + or - 10%. Just be aware of that. It’s more for blood glucose trends than actual, accurate blood glucose, so if you’re diabetic and need exact blood glucose, you probably don’t want to rely on this product. The customer service for this product is EXTREMELY WEAK in my opinion. Let’s face it, we paid Amazon roughly about $110 for a two pack of these sensors. The manufacturer probably pays around $10-15 per sensor. The fact that they refused to acknowledge a faulty sensor and wouldn’t replace it tells me all I need to know. Yup, you guys got me for $110, and saved $10-15 on replacing a sensor, so in theory, you got me, ONE TIME, for $125, but I will never again by ANY product associated with Stelo/DEXCOM, and I will discourage family and anyone else who is considering it, from purchasing one of their products.For what it’s worth ; out of curiosity, just checked other reviews of this blood glucose monitor. They actually have a higher percentage of 1 star reviews than 5 star reviews. What does THAT tell you. AVOID THIS PRODUCT !!!! WOULD NOT RECOMMEND/WOULD NOT BUY AGAIN/ABSOLUTE CRAP !

I used Abbott’s continuous glucose monitor Lingo for a couple of years and several months ago switched over to Stelo. I made the change because Lingo maxes out at 200 versus Stelo’s maximum of 250. I often have glucoses that go in the 200-250 range and Lingo did not tell me how high they actually were.Application of each monitor is quite similar. Stelo differs only in that you actually push a button once you have placed the application device in the proper location and pushed down, while the Lingo applicator fires automatically. Stelo also comes with an additional adhesive ring that you place around the monitor. When done correctly, the attachment is very secure and I had no problem with Stelo prematurely falling off. (I actually had no problems with Lingo either).Stelo takes a reading every fifteen minutes, versus every five minutes on the Lingo. The app on the phone is very good, showing a graph of current readings as well as averages over the past 1, 3, 7, 14, and 30 days.Accuracy of the spot readings was, however, problematic at times. In a random sampling comparing blood prick level to the Stelo, only about one-third of the readings were within 10% of the correct value. Most were too high, sometimes by a lot. One time the monitor showed over 250 while the finger stick showed 167.Stelo says you can contact them if the monitor seems defective, and I did so in this one case. I filled out a form online and they promptly sent me a replacement. Lingo was also quite good with replacing monitors that seemed defective. In that case, I would talk to an actual customer representative.Stelo does not calculate a HgA1c based on average values, but it is easy to do yourself. Despite the discrepancies I described above, my most recent calculated HgA1c based on a thirty-day average was exactly (and surprisingly) equal to a value measured at the same time in a lab draw.Stelo is explicitly intended for people who are not on insulin, and based on my experience, I would certainly not want to use it to estimate an insulin dose. However, if you are a non-insulin diabetic or simply interested in blood glucose trends, the monitor is quite helpful. (Many insurance policies don’t reimburse for monitors in this population.) With the device, you can get an estimate of what type of foods cause glucose spikes and also a rough idea of how high they are. I find a monitor like this is most useful to see which foods cause glucose spikes and to get a rough idea how high the spike is.

I would love to say that the numbers are accurate. But if you poke your finger, you will see they're thirty to fifty digits off. But that's not the main reason why I'm leaving this review. I have ordered through Amazon many times and I've ordered through their direct website stello and the first time I ordered it through stello. It seemed to work pretty good, but the numbers were way off again. Thirty to fifty digits, and when I had one that literally came disconnected after five days. Even after the patch was on, I told them to send me another one, and they never responded back. They wanted nothing to do with it. I tried to call them. I just got a digital bot, and they never helped me. Here is my advice. If you're reading this, i'm prediabetic, and i'm doing the best, I can to keep my numbers low, and i've poked my finger one sixteen times one day, because of so many errors from those glucose monitors that you get at walmart, or any brand for that matter. Long story short, is this? I believe that stello sends all their glucose monitors to Amazon amazon stores them for who knows how long until they sell. And then you get one and number one, the batteries don't last. As long as they're supposed to 15 days, not even close, usually half. If not less and second, the sticky part of the sensor seems to always come off. Whenever I check after about a week, I looked in the mirror one morning and it was barely hanging by the edges. The bottom edges under my arm. And I thought, how accurate could that be? I don't even think it was still in me. But for some reason, I was still getting a number at that time, I was really shocked with that. So while I have used these for 2 to 3 months straight, I will say that you might wanna try lingo. It's a more up-to-date app. It seems to be closer to 5 to 10 digits off. They're not gonna be a hundred percent accurate. Unless you poke your finger and like doing it. But they give you the gist of how you're glucose is going. But the lingo seems to be all right, way better. The very first time I use a glucose monitor which was with lingo. And I'm going back to it now. I like that I can get it at Walmart and I know it's fresh, I know that Walmart says they stock Em every 2 or 3 days, so people are getting Em, they're not dead batteries, they stick on real good. Yes, you can go on Amazon and get patches to cover them. Pulling Em off and it's extremely painful. Just like if you get a stello and you put the patch on, I only did that once after that. It's like tearing a couple layers of skin off your arm, very painful, more than putting it on. In fact, putting it on doesn't hurt at all, so you don't need to worry about that. But just my advice to you. Read this first make your choice. Yourself, i'm going back to lingo, get them at walmart, about a dollar less, you can get two week increments, one pack or whole months and buy two packs, but they're fresh, they're fully charged. And I don't seem to have a problem with them coming off. And when it's time to take em off, they don't hurt.

Stelo CGM Review: My 13-Day Experience as a PrediabeticBackground:As someone with HbA1c of 6.0 (prediabetic), I started using the Stelo Continuous Glucose Monitor (CGM) to get ahead of my condition. I also used a manual fingerstick glucometer to cross-check accuracy throughout.1. 3-Day Update (Early Impressions)Over the past 3 days, I carefully compared readings — taking at least 30 fingerstick samples and comparing each with corresponding data from Stelo. Consistently, the Stelo CGM showed readings 8 to 15 mg/dL higher than the fingerstick measurements.I understand that CGMs measure glucose in interstitial fluid, which can lag behind fingerstick readings from capillary blood by about 15 minutes. That said, the difference I observed was very consistent — Stelo was always higher..My Verdict:1. Stelo is a useful tool for identifying trends and patterns over time.2. It is not as precise for exact moment-to-moment readings.3. For accurate blood glucose levels, fingerstick testing should stay the standard..Notes: However, CGMs like Stelo can be very helpful for daily decision-making, meal timing, and understanding how lifestyle impacts glucose..If you're looking to spot trends and improve metabolic health, Stelo is an option - just remember to double-check with a manual test when precision matters.2. 10-Day Update (Mid-Way Review)By Day 5, accuracy dropped sharply:Stelo showed 25–30 mg/dL higher than fingersticks, even at rest.I fully admit I’ve pushed the sensor hard:-Daily gym workouts, heavy lifting, running.- Swimming 4+ times/week.Applied a Skin Grip patch, which impressively kept the sensor secure through sweat and water.Despite surviving physically, data quality of CGM declined:-Only helpful for general directional changes - rising, falling, or steady.-Not trustworthy for absolute numbers.Decision: I would keep it on for trend watching, but no longer trusted the data for actionable decisions.3. 13-Day Final Update (Sensor Fail)By Day 10:Readings became wildly erratic, jumping from e.g. 120 → 170 → 110 within minutes.No longer reflected any real trend or state.4.By Day 13:Battery died and I removed the CGM.Remarkably, Skin Grip still held tight.Final Verdict on Stelo CGM (Sensor #1)-Days 1–5: Solid performance, good directional data, valuable tool.-Days 6–10: Usable only for trend direction (rising/falling).-Days 11–13: Garbage — data was erratic, unreliable, and eventually the device died.Conclusion:If you're prediabetic and want to learn how your lifestyle affects your glucose, Stelo may provide short-term.But:-Don’t trust the exact numbers.-Be wary if you're physically active — sweat, motion, and water appear to impact accuracy over time.I’ll test the second sensor, but my expectations are modest.

I have been using the Stelo CGM for about 7 months and am just about to purchase the 7th box of 2. I have found it invaluable in figuring out management of blood glucose. The life-time of each sensor is a little uneven, but I have now used 15th sensor. Most have given the full 15 days and with many I have used most of the 12 hr grace period. On one the overpatch came loose about half-way through the 15 days and eventually that sensor failed. Since then I've treated my arm with Flonase and made sure that I can keep the sensor dry for at least 8 hours and have not had this problem. I had several sensors fail late in the 15 days and just replaced them. One failed for no apparent reason early in the 15 days (maybe day 6) and I appealed for a replacement but was denied. I got a prompt notification that my complaint was being reviewed but never heard another word. And herein lies the reason for 3 stars and not 5 stars. But it only took me an hour to figure out how to chat with the bot and how to file a complaint. I was a little irked but not sufficiently disappointed to bother with a review. But this past week I had another occasion to interact with Stelo customer service. It started the day after I started a new monitor. Once it was working and I was getting data, I discarded the applicsator with it's QR code and did not write down the code numbers. Unfortunately the next day I suffereed a cell phone disaster and not all of my data and apps could be recovered. That included my Stelo app. I uploaded the app again and recovered the data from the previous monitors but the new app couldn't pair with the current sensor although the sensor was still in place and presumably still recording data. This should be an easy fix. It must be possible to track a monitor. I probably spent 3-4 hours trying to get past the bot which repeatedly suggested that I could just use the code. I finally talked to a real person, a very nice customer representative who suggeste that I shouldn't have discarded the applicator with the code and should have kept the number. However she finally suggested a number I might try. The monitor briefly came to life before giving a sensor failure message. The customer service representatives told me there was no recovery once the failure message came up. She did provide the forms to file a claim which was denied the next day. This time I was notified. Customer service is worse than non-existent. If the website just said "all users are on their own", users would know where they stand. I probably would not be any more disappointed than i am now and would not have spent the better part of 4 hours on the Stelo website.Free Hint. Keep the applicator until you discard the sensor and write the code down--I use Notes on my cell phone for this.

Update 5/26/26: I gave Stelo another try and I believe there is detail left out on how to apply with a better success rate. Before you press the button, you have to push the device down all the way onto your arm hard enough to not see the clear incasing of the needle (see picture). I left a star off because the adhesive stickers do not last the duration of the device. They should include a sticker for every 5 days. Within 10 days, I have to take the sticker off because at this point it is lifting.Old review March 2026: Both sensors did not work. One sensor never connected no matter what I try to do. I restarted my phone. I uninstall the app and reinstall the app. Nothing would help sync the sensor. So I peeled it off and I tried to set up the second sensor that comes in the box this sensor connected, and I felt hopeful. My first reading was 85 and then it showed that it was drastically dropping. After about 15 minutes, the sensor was coming with a reading of less than 70. Even after I had a piece of candy the number would not go up. I decided to get some sleep and after resting for 3 hours, I woke up and saw that the sensor had stopped reading and disconnected, saying that the cycle was done.I am very disappointed with how expensive this product is and it doesn’t seem to work. The only thing good about this device is that applying it was fairly easy and pain-free.I have put in a claim and complaints with the manufacturer and requested a resubmission for the item that I bought.Unless I can get some working sensors, I cannot in good faith suggest this product.

FINAL UPDATE (April 25) I’ve officially finished my journey with the second sensor, and I’m pleasantly surprised! This time it lasted the full 15 days. I had also +12 h, it seems the Grace Period are designed specifically so you can install a new sensor and let it calibrate without losing data continuity.​When Stelo recently disappeared from Amazon for a few days, I found a solution and bought another "titan" in the CGM world -Lingo. This will be a great comparison!​First impressions of Stelo vs Lingo:​Stelo Cons: It is more expensive.​Stelo Pros: The kit includes an extra protective overpatch (Lingo doesn’t), and the applicator feels much more premium - higher quality, solid, rubberized plastic compared to Lingo’s simpler construction.​This review has already become a "Talmud," so I’ll post the detailed comparison in my upcoming Lingo review. Happy shopping, everyone!------------‐--------------------------------------Why that was in my wishlist? Because I wanted to see what is invisible to the naked eye. Stelo is the first CGM cleared for over-the-counter sale. It is officially NOT intended for people on insulin because it lacks active alerts and frequent samplings. However, it is an invaluable tool for biohackers and individuals exploring their own biology to fine-tune their diet and lifestyle. If you, like me, have an irrepressible urge to control everything around you, this device will become your best ally. It lifts the veil of mystery and shows your body’s real-time reactions to food.​Installation & Setup:* ​Placement: I chose the arm I sleep on the least. Look for "the fluff": the sensor must sit in the subcutaneous fat layer. Do not attach it directly to the muscle. Flex your arm to find a spot that remains soft and stays away from joints.* ​Preparation: Do not use oils or heavy moisturizers on the skin that day. Wipe the area with an alcohol pad and let it dry completely. If the area is hairy, it’s worth using a razor for better adhesive contact. Avoid scars or skin irritations.​How it Works:*​Update Frequency -data syncs automatically every 15 minutes.​* Glucose in the interstitial fluid (where the sensor sits) lags behind blood glucose by about 15 minutes. This is a physiological fact, not a device error.*​There can be a slight margin of error. Especially, the first 24 hours, the sensor is "settling in". I installed mine in the evening, and by night, it showed values at the very bottom of the normal range.​My Personal Experience:​* I took showers and went to the pool, everything was perfect. The adhesive didn't peel or itch.* ​The "Shot": The needle is hidden inside the applicator and is invisible during the "fire." It’s incredibly fast and painless, which was crucial for me as I fear the sight of blood and needles.​*The App Interface. One downside for me is that you can't see specific numbers for past readings, only the current one and the overall graph. The graph lacks a fine grid (e.g., every 10 units); the 70-140-250 spread is too wide for tracking. If I missed a setting for this, please let me know in the comments!​I conducted a small experiment to see how different "shields" affect a glucose spike from a "carb bomb" (a can of pineapple juice).​Day 1: Just the juice (fast spike).​Day 2: Protein first, then juice.​Day 3: Fats first (egg yolks), juice.​Day 4: Fiber (psyllium husk), juice.​Day 5 (The Grand Finale): A complex mix of fats, proteins, and fiber (Avocado + Eggs + Psyllium).The results a little surprised me. The highest spike wasn't from the juice alone, but from juice after protein. Fats and fiber significantly smoothed the peaks. The most intense hunger occurred after drinking juice on an empty stomach, it was actually easier for me to skip breakfast entirely. The most satisfying day was the last one with the complex breakfast. You can see the summarized data in my attached chart. I’ve always known I love fatty foods, despite the common narrative that "fats are the enemy." Now I value them even more—they are delicious and provide long-lasting satiety. Calories matter, but they aren't everything.​My Conclusion:Numbers-whether on stelo, the scale, or a calorie counter- are just numbers. What matters most is how you feel. Understanding your internal reactions turns anxiety into awareness.​I am not a doctor, so everything described in my experiments is my personal user experience. My charts are an illustration of my body’s reactions, not a guide for yours. Any anomalies in your data or questions regarding your health should be discussed with a doctor, not self-treated.​P.S. I have one more sensor left, so my journey isn't over. I think the next part of my research will focus on physical activity!UPDATE (March 26): How I got a FREE replacement.​My sensor died on day 14 , just hours after I posted my first review. The app will ask you to toggle Bluetooth and restart your phone. That didn't work for me.I took a screenshot that my session ended early, just in case. I was devastated because I hate English phone calls - they are a nightmare for me. But I found a way to get a replacement without talking to anyone!​Here is the step-by-step:​Go to Settings -> Support -> Contact in the Stelo app. It will take you to their website.​IMPORTANT: Log into your account on the website and add the address BEFORE starting the chat. If you don't, the bot might glitch and ask you to restart the whole conversation because it won't remember chat history.​Don't send long texts, the chat bot doesn't like "walls of text", just say: "Session Ended Early." It will then trigger the replacement form.​Have your box ready: You will need the SN (found on the side of the box next to the number 21). I checked the installation date in the app, based on the schedule-specifically, when the first entries appeared.​The Result: I submitted my claim on the morning of March 23. I got an email with a Case Number immediately, and 30 minutes later - an approval!​Today is March 26, and the new sensor is already in my hands in Camas, WA. That is incredible speed!Update (April 19). I know how activity influence blood sugar after a "sugar bomb" (pure pineapple juice) right now.* 1 cup of pineapple juice on an empty stomach.​* Compare a sedentary morning vs. two different walking strategies.​Day 1: Bed Rest. Ispent the morning in bed reading books with my daughter. Result: My sugar spiked from 115 to 163.​Day 2: Walking AFTER the Juice. I drank the juice at home and then immediately went for a 1-hour walk. The peak was still high 165, but the duration was much shorter. Walking AFTER helps clear sugar from the blood faster, but it does NOT prevent the initial peak itself.​Day 3: ​I started my walk first. After completing one-third of my usual route, I drank the juice (which I had in my pocket) and continued walking. ​Result: This was the most effective method. The peak reached 145. By "pre-heating" my body began burning the energy immediately.​Pay attention area under the Curve. I looked at the total glucose load on my body:​Day 2 - even with a high peak, the total load dropped by 34% because the sugar cleared so quickly. ​Day 3- the total load decreased by nearly half (-42%) compared to lying in bed.​Bonus Discovery 🥥 ​I also tested how my body reacts to coconut dark chocolate treats like dessert:​1 candy: Almost no change on the chart.​2 candies: Created a noticeable "hill" toward the top.​3 candies: Caused a full-blown spike.​Final Note: The sensor is incredibly sensitive. On the third day you can see chart reversal at the end, because as soon as I returned home and ate my husband's pancake, the reading jumped from 101 to 113.

Check if compatible. I have a fairly modern One Plus phone so thought it would work but even with buying a VPN so could access as if USA not UK it did not work.
