    Very much looking forward to your deep-dive. CGMs are a great tool in terms of recording data - but like any data you have to look at it properly.

    thats all ok . But there is something going on though! I tried it and surprisingly lost 90% of my Cravings for sweets over the day, Eat less portions, and have a way deeper sleep all of a sudden. Loosing weight is a good goal, but I am not talking about counting Calories here. Idc about those monitors right now, bc i am in the Phase of finding out how it feels not to be dictated by Cravings or Hunger all day long 24/7... But I am starting to get courious what ARE the ups and downs of my shugar levels in my blood. Those Monitors are kinda cheap and easy to use . And why not have a tool for yourself for a while to see whats going on and how it Feels, instead of leaving this all to the Doctors all the time...?Nothing wrong with that I say.. . And Btw. unless you have identical twins you cant really compare peoples bloodsugars or glucose levels to one another... bc they are just not the same or equal enough...

    I wore them for a year and a half as a diagnostic tool since blood sugar was affected by a gi illness I had. To my understanding, spiking blood sugar isn't always a bad thing, it's if you're constantly bouncing around in my experience. Swinging 100 one way and the other within the 'healthy range' every three hours or so still feels awful! Highly recommend that doctors get well versed in using these as diagnostic tools with their patients, this would not have been nearly as effective without the guidance I received to get my blood sugar regulated and then we could focus on the underlying problem. Feel so much better these days, don't have to wear these anymore, and I blissfully have no idea what my current blood sugar is.

    Glucose levels are influenced by so many factors: food, stress, sleep, hormones, alcohol, exercise, heat and cold, etc. The value of a CGM is it can help you identify patterns. Glucose spikes are completely normal, what’s important is keeping your variability nice and tight. I think people just need to be educated on how to use the CGM correctly👍🏻

    Diabetic here. Please don't buy these things if your pancreas works. You can be misled because of the following reasons: Your sensitivity to insulin changes throughout the day, so when you eat is a factor Exercise can change how efficient insulin is in your body, Certain foods can prevent spikes in the short term for example high fibre foods Everyone's gut microbiome is different, and you may have a pathology that causes spikes that had nothing to do with food Lastly, a glucose spike will be handled by your sodding pancreas, calm the f down

    Did you know that high insulin causes damage to your arteries? Did you know that carbs causes inflammation in your body and pain? Anyone who has an increase in their insulin should avoid foods that spike their insulin because they will eventually get clogged arteries I know. As stated before, people who are insulin resistant needs to know what foods not to eat meaning they need to know when they get spikes after eating certain foods, and what to stay away from. This is prevention and correction of diabetes and insulin resistance and the cgm is a great tool for that.

    Not sure I agree. I’m insulin resistant, and tracked food while pregnant for 6 months because of gestational diabetes. The certain foods that spiked my blood sugar had consistent spikes within 5 point I’d say. Unfortunately “healthy” individuals vary. I wouldn’t trust any studies unless I knew there was a wider test population and knew what tests were given that determined “healthy”. Also- weight, BMI, age etc.

    CGMs are probably most valuable for analyzing trends in glucose levels as opposed to looking at individual glucose spikes. A single glucose spike is not really that interesting unless it's absolutely massive, but constant glucose spiking/maintained high glucose over long periods is indicative of poor diet or general metabolic issues that can be discussed with a healthcare professional that can help you interpret the data.

    I don’t think we know at the moment! What this study shows is that even in lab-controlled conditions you don’t get the same response to the same meal twice. Is there going to be enough signal in the noise to work out that if you eat pasta when you’re tired the day after an exercise session it’s bad? Out in the complex real world, it might well be impossible to extract meaningful data. We just don’t know at this point, and this study is evidence against the hypothesis that it will be possible.

    Yes the problem with CGM is it can never find out the peak of blood sugar. It reads from interstitial fluid that means if someone is having a actual glucose level of 130mg/dl CGM will not show this and because insulin is getting released also in the body the 130 will be dropping minute by minute that means the interstitial fluid will also be getting lower glucose minute by minute from the blood vessels so due to this the interstitial fluid glucose level will never reach to the peak due to dropping level of glucose. CGM is a pure gimmick.

Once Apple releases the watch with built CGM, it’ll be game over for these other companies which charge a fortune for these disposable devices. I very much look forward to that.

    Your short-term carb consumption history affects current readings. When you eat or snack on carbs you spend your rapid release insulin storage and it takes hours to replenish it. Even a small amount of carbs can cause a big spike if not given enough time for beta cells to recover its insulin storages.

    This one is bad advice. Of course, a detailed measurement by CGm requires a detailed tracking of the context. A 2-dimensional approach like measuring grams of carbs is certainly no sufficient. It is probably not even about carbs themselves, but the context, which may be even more important than the carbs. (Ii thought you were a biologist, are you?). CGM is not a CCM, it is measuring glucose, NOT carbs. It is precisely the non-carb component which those devices allow you to learn about. For example: please tell me how a HbA1C of 5.8 is possible with less than 30% carbs evenly distributed, no free sugar, tons of fiber, on a calorie restricted, low protein diet of 2000 kcal per day? see, only a CGM can answer that. Eating habits, meal composition etc etc are all documented to be important factors. So it is VERY easy to create a "random" cloud of readings

    Telling healthy people to look at their blood sugars in case it spikes is a clear example of the blind leading the blind and will only lead to loads of stress. Blood sugar spikes don't matter. This happens because (surprise surprise) you get energy from food. What you get from your food goes into your blood (specifically the plasma) and it takes a little time for it to get used or stored. What you ate, how much you ate, what you ate it with, what you drank with it and how much, what your body is doing, what you were doing recently, time of day and more all affect how much of a spike you get and this is all normal, it doesn't matter. It's not a bad idea for the average person to know what their observations are on average. This would be at most, once a week finding out what your heart rate, blood pressure and blood sugars are at rest, but (unless specified by a doctor or other professional) that should be the most you do. Obsessing over medical observations leads to stress and no observable benefits, it's best not to worry about it. If you have a problem, see your doctor.

    We live in clown world. Your blood sugar is SUPPOSED to go up after a meal. A "spike" in blood sugar isn't bad. What's bad is if it goes up super high and stays elevated for a long period of time. That is causes by insulin resistance. And what causes insulin resistance is FAT. Dietary fat and too much fat on the body. Look up Mastering Diabetes or McDougall to learn how to fix insulin resistance. It's not the carbs! It's the fat that causes the problem.
