    Thanks for posting this video (and your other ones). I have been eating porridge for breakfast for the last 15 years. 13 years ago I was diagnosed with diabetes. I have been using a cgm now for 3 months. I stopped the porridge yesterday. Today was the first day with no insulin and no spikes.

      I had a patient on 20 units of long acting insulin in the morning. He would have a hypo most afternoons! I stopped his porridge and his insulin and the next day he was terrific. His Hbaic is 5.2% off all insulin. So it sounds like you are similar!

      I'm very interested: my girlfriend eats lots of 'Bircher' muesli. A very simple version of it: porridge oats soaked in cold milk with maybe just 7 or 8 raisins. I've always assumed that not cooking it might result in slow release of carbs and lowish blood sugar spikes. Might this not be the case? [Ah: 7:43 - Bircher's also potentially a problem...]

      Oatmeal, which most people consider "healthy", has a macronutrient profile that's over 90% carbohydrates. Porridge is even higher.

      Thank you Penny. I have stayed off the porridge but I had to go back to the insulin. I tried stopping it again a month ago but blood glucose became unstable within a week. I have a cgm. Thankfully my readings are still improving with a Hba1c estimated at 7.1. I was about 5kg overweight and that is now dropping. Energy levels are improving and brain fog has lifted.

      I have oatmeal with 300 g of skyr yoghurt which is very low in sugar and very high in protein, + half a green apple or a full one mixed in there, delicious and keeps me full and satisfied for hours, no spike. I'd never eat that alone or just milk tho.
      Also need to mention, I'm in France, might be different oats.

    I am reactive hypoglycemic also. I have the same reaction to oats as Doctor Figtree. As I have aged, my A1C has moved into the pre-diabetic range. I purchased a CGM about 2 weeks ago so that I could get a closer look at my blood sugar. The CGM data revealed to me that my blood sugar levels were all over the place. My lows were around 55mg/dl and my highs were at 180mg/dl. As I started watching my carb intake, I was able to remove the highs and the lows from my blood sugar range. Now I am between 88 and 135. Within a week I notice a drop in my weight, and I was feeling better overall. For me, the CGM is a window into how food effects my blood sugar so I can make the corrections now before it is too late. Thanks for the video; conformation for me!

    This was SO informative! She experiences what I’ve been dealing with for most of my life. A huge spike in blood sugar and then a big drop when I eat certain things - mostly grains, even whole intact grains. When I was diagnosed with reactive hypoglycemia some years ago I was told that it was a rare condition. I’ve discovered since then that a lot of people have it but most people don’t recognize it fir what it is. I tried an experiment based on info I got from your previous videos in that I ate a healthy serving of protein prior to eating oatmeal. It worked! My blood sugar only rose 30 points rather than 100! But I think that the best thing for me to do is to just stop eating those things that causes the high/low roller coaster. Those spikes really can’t be good.

    • @nourishedbyscience
      @nourishedbyscience  ปีที่แล้ว +11

      Yes, I agree that these issues do seem more common than we used to think. Now, with many people who don't have diabetes wearing CGMs, we are getting much more data, anecdotally and also from scientific publications, suggesting that spiking followed by hypoglycemia is not all that rare even among people with normal fasting glucose and normal HbA1c.

    Thank you for this! I've been having the same problem for years. I've been having horrible anxiety attacks and sometimes depression out of no where and recently found out it was my reactive hypoglycemia that caused it. I've found that I also get the same reaction to sugar free foods.

    • @RickinICT
      @RickinICT 8 หลายเดือนก่อน +2

      I wonder if the reaction to sugar-free foods is because when you taste the 'sweetness' of the food r beverage, your body dumps a first-phase insulin response in anticipation of the increase in blood sugar. Of course, since the 'sweetness' it detects isn't really sugar, there's no glucose spike. Instead, all that insulin just drives your regular glucose into your cells and out of your blood, causing hypoglycemia.
      I always had a similar reaction to drinking an artificially sweetened beverage on an empty stomach. I get a little dizzy and 'punchy' (almost like I've got a slight alcohol buzz). I never really thought about the blood sugar angle before. I quit drinking soda altogether many years ago now, so I hadn't thought of this reaction in years.

  • @lauraleilyn
    @lauraleilyn ปีที่แล้ว +13

    Finally received this diagnosis after years of symptoms. The hypoglycemic effect really knocks me out, and usually comes on very suddenly. I become so hazy and very cold, and fall asleep drooling for about an hour. Not cool when driving....
    I've been on a very low carb diet for a couple of years now and it has helped tremendously. but I must say that it does occasionally still happen even with a protein rich meal. It seems like after an extra hard workout or maybe if my sleep is off, idk.
    Also, I learned that any amount of alcohol has the same effect. Cutting it out entirely has been beneficial in every way :)

      I deal with reactive hypoglycemia post meals. Also exercise induced hypoglycemia. Even a walk I’ll crash into the 50’s. I also have it while sleeping. I have to treat and eat during the night several times. It is so hard on my body. Still trying to figure out what diet to follow. I always have a protein shake before a complex carb meal, which includes fats and fiber to help stabilize, which helps with the spikes. But I always have the crashes. All day long. Randomly. Very frustrating. Thinking of trying a very low carb diet, carnivore or keto.

    @lauragaimon7742 ปีที่แล้ว +4

    Great video!! it helps to realize I am not crazy. This is how my doctor treated me when I went to the Dr with my glucose monitor, asking if I was feeling bad after a "healthy" breakfast (bread with jam) I was spiking and falling down (from 210 to 50) . And he told me it is normal to spike and you are healthy because your body recovers by itself. What an advice coming from a Dr.!!! I ignored it and started to do my own research, and after doing low carb and eating more consciously about what I eat, the order and the combination, I feel much better. THANKS!!

    • @nourishedbyscience
      @nourishedbyscience  ปีที่แล้ว +2

      Thanks for sharing. Yes, bread with jam is an extremely glycemic meal, and really not to be recommended, not even for people with normal glucose tolerance. Based on my research, an increase in blood sugar to 180 mg/dL or higher is not physiologically normal, and reactive hypoglycemia is also not normal. Good for you for educating yourself. Just make sure to be clear that being on a lower carb diet may impair your first-phase insulin response, so while eating generally low-carb, we need to stay particularly clear of highly-glycemic naked carb meals.

    I was diagnosed with reactive hypoglycaemia in December 2022 and was under the assumption that once the blood sugar goes low they are not coming back to normal range until i eat something. This was not completely true, my blood sugar did come back to normal range after the episode even without eating. With the help of CGM I discovered this and now I am aware how high carb and refined sugar behave on me. My anxiousness to eat every few hours is now reduced and this is because of CGM. I always want to try the CGM but this video pushed me further to buy one. Thanks for the video and the interview.

    • @susankaroly-smith2073
      @susankaroly-smith2073 ปีที่แล้ว +4

      Yes, I had the same experience! Once I was on a walk and the CGM gave me a warning as my glucose was falling too low too quickly (due to the excercise, I expect) - I felt a bit shaky, but I recovered quickly without eating anything. When I got home, I could see that my levels never actually reached the hypoglycemic range - stopped falling at exactly 3.9 mmol/L (70 mg/dl) and recovered without any intervention. Now I don't freak out if I feel an episode developing because I know it can reverse itself - still it's better to avoid them if possible as they can be scary!

I had been experiencing exactly what the doctor is talking about and I have been explaining to doctors with the horrible feeling, the anxiousness frustrating etc. you name it! Have been hospitalized couple of times with symptoms that I thought only God will understands me. Because you talk to doctors and people and they tell you you are anxious for nothing. And the sad thing you want to hear is to find a way to manage your stress level. Like you are causing your own problem. I have been experiencing this almost a year now with admissions yet no solution or find the cause of my symptoms. At times my sugar levels will be 60s feeling like passing out. But I am not diabetic so no one is taking me serious.

    Thanks for another great video. After watching your videos, finally felt like I was listening to someone very reasonable. It feels like when it comes to diet, masses are always chasing different extreme diets, like Keto or complex carbs or whatever. In my view the best diet is called moderation, eat in moderation with a mix of different healthy foods, you have nothing to worry about.
    After watching your videos I was very much inspired to buy the CGM, so over the black Friday sale (over $200 for 2.... very expensive without prescription) got the Libre 3 for both me and wife. Both me and my wife's A1C hovers borderline pre-diabetic around 5.7 or so. We did not change a thing on our diet, we just wanted to see what our bodies does after every meal we eat. The results were truly eye opener for us. We rotate breakfast among different things we consider 'healthy', the one that barely budged the needle on sugar was eating two poached eggs, followed by an apple. I have been eating that most mornings for many years now. Even homemade fruit smoothie with just water and ice as a base was not that great, but what that means is, smoothies are usually bad, but not fruits eaten by themselves.
    Eating white rice with animal protein increased the sugar the least (around 140), but rice with vegetables and lentil soup caused spike as high as 160. I experimented with the idea you presented in a different video about freezing the carb after cooking. So started cooking rice good for few days and left them in the refrigerator. Interestingly, there was no change for us in the CGM reading between freshly cooked vs refrigerated. I guess different people react differently to same food.
    As a part of our experiment, we did confirm that even a gentle walk after every meal greatly reduces the chance of a huge sugar spike. The sweat spot seems to be walking 30 minutes after a meal.
    Last but not least, being a moderate scotch drinker, I was very excited to find out what CGM will show after I start drinking. Surprisingly, no matter how much carb I ate along with my scotch, my blood sugar dropped to 85 and it stayed there for 2 to 3 hours. Finally after 4 hours or so, the blood sugar started to spike as if I had just eaten an hour ago. Same behavior with beer even though beer has a lot of carb.
    Did a quick google, and read that after sensing alcohol, liver deprioritizes sugar processing and starts processing alcohol, so sugar level drops because processing sugar takes backstage for a bit. Is that a correct assessment?
    Again pretty amazing to see it firsthand!!!

      The impact of alcoholic beverages on blood sugar is complex, and varies greatly depending on the type of beverage consumed, the timing relative to food intake, the composition of that food, and there are also big differences between people in this regard. I'll make a separate video about alcohol and blood sugar regulation soon, as it's been requested by several people.
      Best wishes to you and your wife.

      This is the best video I've seen on this issue, thank you doctor and thank you for having Dr Penny on to share her experiences.
      Like Dr Penny, I've always had a tendency to go hypoglycaemic after a carb-based breakfast, and discovered that a hearty eggs and bacon breakfast fixed that problem (I have now stopped having them on toast).
      Two years ago I underwent an Ivor Lewis Esophagectomy due to oesophageal/stomach cancer. Since my stomach is now a fraction of its original size, I now suffer constant bouts of dumping syndrome, both early and late. The 'late' episodes almost always bring on episodes of hypoglycaemia, sometimes seriously low (2.4mmol/L).
      I have used Libre2 CGM's to learn of my blood sugar variations but due to the high cost I'm not using them presently.
      It's now obvious to me after watching your video that excess carbs are the cause, and although I had cut down knowing they were bad, I now will be making more educated decisions to reduce carbs further.

    My personal experience confirms Dr. Figtree's hypothesis. My husband was a type 2 diabetic and I suffered from reactive hypoglycemia. We started a low carb diet, which cured his diabetes, but the diet also cured my reactive hypoglycemia. It's interesting that adding fat can prevent the massive spike and subsequent drop. I miss oatmeal, so maybe I'll try it as a side dish to a high fat meal on occasion and see what happens.

    I think this was one of the best videos to date! 🥇 A few observations. The poor who could use a CGM just can't afford it. Many of them do takeout with delivery charges 33:23 when they should make their own meals so more education is needed. A few years back I became tired after having my weekly pizza 🍕 in my late 50's, beginning of last year January 2023 I started making my own 🍕. Using a no sugar, some fiber, wheat crust & control the quality of toppings with protein & some greens. I also just started grating my hard cheese. I'm not getting sleepy after my pizza anymore. I also removed over 17 days of calories. The one disagreement I have with Dr Lutz is that I believe in count cal's & knowing your macros is very beneficial. Today when I have pizza 🍕 my total carb's for the day are now in the low 30's. My total sugar intake is 45g with an equal amount of fiber 45g making my net sugar zero. This has been a three year journey all changes done based on my own observations & before watching these type of educational video's. Last years blood work were mostly optimal too! Looking to tweak that a bit more this year. I hope some of this might help others make changes for their health. You can do it! 🍀

    I have the same diagnosis as Dr. Figtree. I took the 6 hrs glucose tolerance test and at the 3rd hour my BS spiked up to 200 and dropped to 32. It was horrible. Took me years to be able to regulate my BS. I cannot eat too much in one sitting. So I nibble all day. Salads do help me a lot. And yes, constantly hungry in the 3-4 hours.

      @@nourishedbyscience Yes, my primary doctor referred me to two endocrinologists and neither could figure out what was causing the RH. It’s very strange. All the doctors were certain the condition would lead to diabetes but it hasn’t. All grains and grain products cause my RH along with concentrated sugars. Dried fruit by itself, like the raisins I carry for extreme lows, will affect me the same as grains. Raisins work great to raise a bad drop but I need to get to a good protein source within an hour to prevent a rebound. Yet I can put two cubes of table sugar in my morning coffee and my blood sugar remains stable. I guess everyone has different triggers and maybe that’s why a physiological cause is so hard to find.

    Hello Mario, I just recently found your channel and have watched a couple of your videos. Thank you for your videos and expertise. I had an annual physical this past March and was diagnosed with Prediabetes. My hbA1C was 5.7 and my fasting was 99mg. Previous to this discovery, I had been working on losing weight, by reducing my caloric intake, to reduce my blood pressure and dependence on BP meds. My physical , in March, was at the time that I had dropped from 213 lbs down to 180 lbs for a total weight loss of 33 lbs. I was taken off of my BP med at that time. I purchased a glucose monitor and started checking my glucose levels 4X /day. Once for fasting and then after 3 meals/day. Before I lost weight, I thought I was eating healthy meals. For breakfast I would eat Minute Oatmeal/daily loaded with fresh fruit. One cup of blueberries, 2 slices of Cantaloupe, a handful of Walnuts, 2 slices of Pineapple, 3 to 4 Strawberries and 1 banana! I must've have been consuming 140 + grams of carbs! Also, all that fruit turned into sugar quickly. I constantly ate bananas and other fresh fruit at each meal. I'd wager to say that that's what triggered my hbA1C to rise and or triggered insulin resistance. I'm 76 years old. My father and an older brother were diagnosed with Diabetes/Prediabetes respectively. My father didn't develop Diabetes until he was in his late 80s. Currently, I'm not eating any sweets, bananas(less fruit) nor any white breads, also I only eat about 6 berries like raspberries, black berries or blue berries and a half of 1 strawberry. My fasting glucose now ranges from 86mg - 92mg. One hour after eating, my glucose registers usually less than 140 and sometimes 145 but most of the time it's in the 120s. After 2 hours my glucose registers around 102 except when I'm at 145mg it sometimes doesn't drop much or drops down to 125mg. Is the most accurate reading 2 hours after you eat or 1 hour? Also, I have continued to lose weight and have stabled out at 172 lbs. I'm trying to gain some weight back to 180 lbs but am have a difficult time gaining while not consuming too many carbs. I've added almond butter, cheeses, butter on toast. Typically breakfast is 2 eggs with 2 Ezekiel pieces of bread, a handful of Walnuts and sometimes a small container of Chobani zero sugar Yogurt. I alternate breakfast with steel cut Oats, with Walnuts, some almond butter , Yogurt or 1 egg. No matter how much fat I add I'm still not gaining. Should I go see an Endocrinologist to rule out Pancreatic Cancer? How can I gain back some weight? Sorry for the lengthy comment. My wife and I also walk almost daily so I end up burning up some of my caloric intake walking. Thank you , in advance, for your response.

      Hi Gary,
      Thank you for sharing. To your questions:
      - I cannot answer your question whether 1 or 2 hours after a meal is more accurate. Both together matter, and also the level around 30 min after the meal. If you are up for it, you could measure 30 min, 60 min, and 120 min for a few meals only, to see your typical pattern to your typical meals and then measure only at those time point(s) that are most informative to you.
      - You mention that you think that your high consumption of fresh fruit and berries may be a cause of your elevated HbA1c and potentially insulin resistance. You know your body best, but from a scientific point of view, there are no data to suggest that eating fresh, whole fruit or berries has negative long-term effects on blood sugar regulation. And even the acute glucose response tends to be modest with fruit and particularly berries.
      - You also seem to be wondering why you continue to lose weight. That's something I cannot comment on, because that would cross the line to providing personal medical advice. I therefore suggest you discuss this with a physician or dietitian.
      Best wishes to you,

I exercise for more than 1 hour every day and eat almost a non-carb diet every meal (with the only carbs in beans and nuts). With an HBA1C of 6.0, a fasting glucose level of 96-106, I am concerned that there is something else that is not picked up in my blood glucose tests. I do not have a CGM but intend to get one so that I get better data throughout the day. Not only I am concerned with my pre-diabetic condition, I am also concerned about cancer risks. I have lost about 5kg (11 lbs) over the last five years and now weight a meager 110 lbs. I wonder if this weight loss (and inability to regain any weight) is due to the lean diet (with plenty of protein and fat but no carbs) or due to the regular exercise (more than 1 hour per day with both cardio and weight training) or due to something else. Any comments would be greatly appreciated.

    I've seen some tech bros that started wearing CGMs when they don't need one, because they think the key to longevity is to have as little spiking as possible. It seemed dumb to me, but my mom had some extras so I tried it. And I'm SO GLAD I did! My a1c has been hovering right under the pre diabetic cut off for years and with both of my parents having type 2, I figured I'd just get it eventually and there wasn't much to do except try my best to eat healthy and exercise. Despite doing my best though, I'm still carrying 40 or 50 extra lbs. But within just a few days of wearing the CGM I figured out the pattern that was keeping my bg up, and I was able to change things up and now I'm excited for my next doctor visit. My sugar cravings and urge to overeat disappeared. I'm losing weight. I lost 6 or 7 lbs in one month WITHOUT TRYING. I see a lot of people jumping to ozempic, but I think they should try a CGM first. There might be something that's easily fixable.
    In my case, it was my gastroparesis. When food sits in my stomach, my bg stays elevated. Not crazy high. But if it's at 120 all nigtt long, every night, it causes a problem. So I started intermittent fasting. I've done it before, but looking back, I was still having tea with honey during my supposed fasting times and I wasn't doing it every day. I was having "cheat days". But this time I was strict. My numbers started improving right away. About 10 days into it, I noticed I wasn't craving sugar anymore. Less than a month in, my urge to overeat disappeared. And the thing is, everyone with gastroparesis is told to eat small meals throughout the day. But in MY case, it was screwing me over. I deal with nausea, bloating, etc but I don't puke. So shortening my eating window hasn't caused a problem. If I was the type of gastroparesis patient that struggled to gain or maintain weight, it might be an issue, but I'm clearly getting enough calories.
    Other than that, I learned I can't eat naked carbs. I knew you were supposed to pair carbs with fat, fiber, and protein to prevent unnecessary spiking, but it wasn't really REAL to me until I had the numbers right in front of me all the time. So now I eat at least a good bit of protein with each meal and snack. I struggle more with fat and fiber because of the gastroparesis but protein seems sufficient to prevent spiking.
    My bf actually does have type 2. You wouldn't know it by looking at him. He's very muscular and fit. He refuses to do fingersticks and just finds out every doctor visit if he's on the right track. His last visit 2 days ago he did not get good news, so he let me put a CGM on him finally. I'm excited to see what he finds out.
    I don't think I need my CGM long term. Now that I'm doing better, this will probably be my last one. It comes off today. If anything changes, or I start struggling again, I'll put one back on. But as a "healthy" non diabetic person, this was an invaluable and illuminating experience. I'm really hoping I can head off the diabetes. Maybe I'm not destined to get it just because my parents have it. I have information that they didn't have. They both wear a CGM now, but imagine if they'd been able to wear one BEFORE they became diabetic. Honestly, I think everyone should try it for a month. I'm sending a few to my friend in the UK that can't afford them out of pocket. His wife is struggling with gastroparesis and reactive hypoglycemia. I hope she finds out as much as I did so she can start feeling better.

    I have four years had issues with reactive hypoglycemia and have managed it on my own with a low-carb diet. One thing that makes it concerning is that depending on what activity you are doing when you have that low blood sugar,such as driving or doing something where cognitive accuracy matters greatly, the impact can be very important. I get something like brain fog and feel weak an unable to concentrate when this happens. Not good.

    Although not as convenient, you can also use a standard blood glucose monitor (ie the kind that requires you to prick your finger to get a drop of blood), to see if you suffer blood sugar spikes. If you test (say) 30 minutes after you eat, you can see if your glucose spikes. The advantage of a standard glucose monitor is that it is cheaper than a CGM.

      To figure out if your struggles are related to hypoglycemia, I think wearing a CGM for 2-4 weeks can be very helpful. One mixed meal test can be hit or miss. If you just eat your regular meals and can see the ups and downs in your blood glucose, that can provide much more insight.

If I eat protein and fat first then the carb 5-10 mins later my blood sugar spikes a little then stabilizes.
    I’ve had reactive hypoglycemia for 14 plus years and have seen many doctors in regards to this and never knew what was going on until now. I still have about 30 more lbs to lose but I’m pretty sure I’ll have to eat low carb for the rest of my life. 😊

    Since blood sugar spikes occur after meals, prior to buy a CGM, I thought to do it the cheapest way, by using a simple glucometer with which I took for few days FG and BGs after one hour and two hours post each of the main 3 meals. Enough to get an idea of glucose behavior, actually shocked by the 190 reading one hour after dinner on which I had crab hamburger, green salad (oil & vinegar), 75gr of homemade bread and 1 free alcohol beer (330ml), instead of 130 (heavy breakfast with cereals, oats, milk, fruits, nuts), 150 (100gr pasta lunch, glass of wine, strawberries and 15gr of dark chocolate).
    FG averaging around 90, no hypo glucose effects, I realized, watching the table kindly provided by you, that beer has a very high glycemic index, but never thought it could be so devastating?

    I have some similar experiences to what is described here. I started wearing a CGM periodically because I was feeling groggy, flushed, diaphoretic and unwell in the afternoons 1-2hrs after eating (particularly higher carb or more processed foods). I didn’t find a clear answer with random/symptom triggered blood glucose testing. I thought I might have postprandial hypotension, but didn’t see associated low blood pressures when I checked. I later performed a home OGTT and noted very high sugars at about 45 min postprandial (204mg/dl ) but didn’t meet criteria for actual DM or pre-DM since the sugars came down into the normal range soon after. In the course of my normal (not low carb diet), my sugars are usually in the ‘normal’ range, but when I eat more simple carbohydrates (particularly without fat and protein alongside) I get sugar spikes to about 145-150mg/dl followed by a pattern of lower level spikes for the next few hours…these hours are associated with feeling headachy and mentally sluggish. eating an apple for an afternoon snack will give me symptoms, but an apple with peanut butter may not. A serving of fresh grapes will trigger symptoms, but grapes with cheese usually will not. My worst symptoms are temporally associated with the time right before and right after the large initial spike….my question is what does this signify? I know I have some insulin resistance because I have polycystic ovarian syndrome have been on metformin for over a decade as treatment for that. I try to generally eat healthy and I have a normal BMI currently. My hemoglobin A1c is normal. I have interpreted my CGM results/ symptom pattern to signify that I have much more insulin resistance than my lab results indicate and maybe even have occult diabetes that is masked/compensated by the metformin and health conscious diet.

    I really enjoy this kind of content and if wish there was more research and detail on the actual intake patterns of food
    The salmon and chocolate cake example is a really interesting example and exploring all other potential combinations would really prove valuable.
    This could help us as a population diminish the effects of certain foods that are just too comfortable to avoid all together. The combination and that matched with the total calorie intake over a period of time would really make a big difference.

    Thank you both for the excellent video. I certainly recognised myself jn Penny s experiences. The CGM was an eye opener and explained so much about why i can feel so tired and low. Those low sugar episodes are horrid and i find now i can tell my sugar is high by the jittery dast heart beat feeling. Porridge was a shock when i saw the blood sugar spike as i love porridge! After lots of experiments, i found a spoonful of chopped nuts in a grain and seed porridge brought the spike down to normal and is delicious. Thank you so much for these great videos.

    • @nourishedbyscience
      @nourishedbyscience  29 วันที่ผ่านมา

      Sorry to hear. I strongly recommend you discuss this with a doctor as soon as possible. There are medical conditions that can cause this, and they are not to be taken lightly.
      Aside from this, once you have been cleared by a doctor, you may want to experiment with this here:
      - Keep your intake of carbs modestly low, but at a regular level from meal to meal. That is because your beta-cells' ability to make insulin is reduced if one meal is very low in carbs, and that can give rise to a spike followed by hypoglycemia. Therefore, if you eat high carb one meal and low-carb the next few meals, this can result in a propensity to spike excessively to any higher-carb meals. And spikes are often a cause of hypoglycemic episodes.
      - Particularly limit all high-glycemic index foods. I have a video and a poster about this if you search on my channel.
      - Always eat a bit of fiber-rich veggies or a salad first, then a few bites of a protein-rich food, and then some lower-glycemic index carbs
      - Also minimize very low-carb, high-protein meals. Note that protein also stimulates insulin release, and this can trigger low blood sugar in some people.
      - For someone like you, it may be useful to always include some fat in all meals. A high-fat intake can keep blood glucose elevated for an extended period of time, which isn't usually ideal, but can be helpful to minimize the risk of hypoglycemia.
      Let me know how this goes.
      Best wishes,
      Mario

    I have been suffering from this my whole life I described it to my thyroid diet (endocrinologist ) and he told me 20 yrs ago . He said we don’t need to test you , that’s what you have . I will have a full blown melt down one hour after I eat a donut . I feel like I am going to pass out , start shaking , become confused , and sometimes start crying and sweating for no known reason . My sister , dad, and niece have had similar symptoms their whole lives. I am now 58 yrs old and just had my first A1C test , coincidently my accident , because the lab ran it when the test wasn’t ordered (they were just ordered to run TSH thyroid test . The results came back and the nurse said casually that “you know your A1C is 5.8 so you are prediabetic. “. Gee , my endocrinologist isn’t concerned and didn’t notice . An endocrinologist is a diabetes doctor !!! BTW, I am not overweight and work out regularly

    I get glucose spike and severe hunger after having oatmeal. My blood glucose used to drop so low I got the shakes and dizzy spells. I have found a lot of medical practitioners who advise me to drink a glass of orange juice or eat a slice of bread to bring my blood glucose up to a normal level. I consider such advice as wrong.
    Yesterday I got up with a fasting glucose of 3.5 mmol/l, had a cup of coffee, took the dogs for a 60 minute walk after which I visited 4 stores for grocery shopping, all of it I classify as very mild exercise after which my glucose tested at 4.3 mmol/l.
    My observation is that in the event of very low blood glucose a short brief exercise will allow my body to react to the possibility of hard work and automatically correct my glucose level.
    In the past I have even peddled my exercise bike very hard for two minutes with the same result so definitely no orange juice or bread for me.

    My CGM has changed my life as well. After gaining 30lbs during covid, I searched for a plan that would help me lose weight and after wearing a CGM, I see that I have hypoglycemia….which explains why I so quickly gained weight during covid (i abandoned my low carb lifestyle). I eliminated all high carb foods and I now have lost almost 35lbs since last October (2022). I now feel so empowered to avoid foods that spike my blood sugar and I’m so much more happy.

    Thanks for the video. When I eat carb rich foods like 2 slice of bread my sugar goes up from 100 to 200 in 30 minutes and come down to 100 in an hour. But the story is different if I exercise after this meal. If I exercise my sugar goes down to high 50s and recover after 5 minutes and go back to 100 s which is my baseline. Luckily I was not symptomatic . CGM helped me to identify this problem. If I exercise on empty stomach then my sugar doesn’t drop and stay very steady. Very interesting findings about myself. I am going to to cut down my carbs and add more fat and protein to reduce the spike and resulting excess insulin production.

      Nora,
      I know that the narrative in the low-carb community tends to be that carbs are bad, and I respect anyone's opinion here. However, I will say that fully glucose tolerant people can eat all the carbs they want and still keep their blood sugar in the 70-140 mg/dL normal range. And I don't see any evidence that fluctuations in that normal range are harmful in the long run. Also, some of the healthiest and most long-lived populations in the world eat largely plant based high-carb diets; sure, that's observational evidence, but we don't have any such compelling long-term outcome data on any low-carb diet. And I am saying that as someone who absolutely is a fan of low-carb or keto dietary approaches. I just feel that if the data suggest that there are many paths to health, then that's a good thing. Low-carb is not a great fit for everyone, just like low-fat is not a great fit for everyone.
      Warmly,

    At age 34 I was diagnosed with gestational diabetes and was told I was hypoglycemic at times I remember the shakiness if I ate bare carbs but was offered no coaching/advice. Now at age 72 found out I am pre-diabetic and I am wearing a cgm. If I eat any carbs like yams, beans etc I spike way up and then get reactive hypoglycemia -so it continues. I am slim, have always exercised and eaten healthy foods. Now the only things I can eat without big spikes are protein (mostly salmon) and veges. Wish I had had the cgm and knowledge I now have all those years ago and likely would have a lower HB A1C now.

    • @nourishedbyscience
      @nourishedbyscience  10 หลายเดือนก่อน +2

      It's wonderful to hear that you are figuring this out. However, please consider that blood sugar spikes followed by reactive hypoglycemia could be made more likely if your general diet is low-carb and you then consume a high-carb meal only occasionally.
      In other words, if you want to figure out your body's ability to handle different high-carb foods, it would be best to do this after having eaten a normal- to high-carb diet for at least a couple of weeks. That is because a low-carb diet lowers the first-phase insulin response, which makes spikes more likely.

    You mention that blood sugar spikes and reactive hypoglycemia in non-diabetics is an "under the radar" and potentially very common phenomenon. May I suggest another phenomenon that might be under the radar: raised early morning blood sugar levels. I'm non diabetic, and non pre-diabetic and recently purchased a glucose monitor. I did this because of the conflicting recommendations about "healthy" foods (for example oatmeal is often recommended as a healthy breakfast), and another youtube channel suggested the only way to know for sure about what foods spike your glucose is to actually measure it. Anyway, I've started measuring my waking blood glucose and find that it is sometimes unexpectedly high: commonly around 6.0 mmol/L (108 mg/dL), but sometimes as high as 7.0 mmol/L (126 mg/dL). I know that diabetics can experience an early morning glucose high, but perhaps this phenomenon is more common than realised in non-diabetics?

    • @nourishedbyscience
      @nourishedbyscience  ปีที่แล้ว +2

      Yes, the dawn phenomenon. It's a little less 'under the radar', I feel, because fasting glucose is one of the diagnostic criteria for pre-diabetes and diabetes, whereas blood glucose 30 min or 60 min after the meal are not considered at all.
      One thing you may want to consider is that there are circumstances where the dawn phenomenon is more pronounced. A common one these days is people on very-low-carb or keto diets.
      If there is no good explanation for this and fasting glucose concentrations >6 mmol/L are commonly seen, it may be advisable to speak about this with a healthcare provider.
      All the best,

    One major thing i will add to this is, it could be the mix of high fibre or high protein with sugar that will cause high spikes then hypo, it happens to me because these digest more slowly and the insulin over responds. I have liquid sugar it doesnt go near as high and goes back to base line. I think the slower digestion is causing the spikes and low blood sugar after.

    Fascinating. I have had reactive hypoglycemia for decades. I Found long ago moderating naked carbs is effective. I am now pre-diabetic and get spikes depending upon my food intake, high GI or large meals. But my concern more than the spikes is the increase in my running glucose average of 110 to 120. I literally run most of the day at the level. I eat low carb, low GI, lift weights, walk after eating but I can’t get the average down. My body will moderate down from a spike quite quickly just like this healthy doctor. But how can we moderate down the running average. I’m not certain spikes are all that surprising. It seems to me at a cellular level my body no longer uptakes the carbs. I appreciate your content!!

    Again your videos spark much interest and some frustration on my part. I exhibit both blood sugar spikes and reactive hypoglycemia. After years of being told there was not a diabetic drug that fit my situation (CPSS) I came across the subject of Alpha-glucosidase inhibitors, i.e, Acarbose. I tried it for a few months but the GI problems were too much. Acarbose raises both primary and secondary BA's. I already have too many of these. Acarbose also changes the composition of the microbiome and in my case causes dysbiosis. It did however lower my BS spikes by about 20% and alleviated my reactive hypoglycemia to a certain degree. Acarbose works in the enterocytes where it inhibits the enzyme which converts disaccharides to Monosaccharides (glucose). I then started to look for a natural element that would do the same. I wear a CGM and I noticed that my sugars didn't spike and I didn't have postprandial somnolence on "Taco Tuesdays". I looked into this and there it was. Capsaicin is a natural Alpha-glucosidase inhibitor (among other things of value to the hyperglycemia issue). It ranges between 20-80% (depending on plant variety )as efficient as acarbose but so far it doesn't have the BA and dysbiosis issues. One thing to note is that AGI's by their nature only work on glucose derived from the gut (diet) and not glucose the liver uses from storage and Gluconeogenesis which in my case is a sizable amount because of my BA/FXR situation.
