Why Your “normal” Blood Sugar Isn’t Normal (part 2)

Why Your “normal” Blood Sugar Isn’t Normal (part 2)

Hi, I just found this site and would like to participate. I will give my numbers, etc. First, my last A1c was 6.1, the doc said it was Pre-diabetes in January of 2014, OK, I get it that part, but what confuses me is that at home, on my glucometer, all my fastings were “Normal” however, back then, I had not checked after meals, so maybe they were the culprits. Now, I am checking all the time and driving myself crazy. In the morning sometimes fasting is 95 and other times 85, it varies day to day. Usually, after a low carb meal, it drops to the 80’s the first hour and lower the second. On some days, when I am naughty and eat wrong, my b/s sugar is still low, and on other days, I can eat the same thing, and it goes sky high, again, not consistent. Normally, however, since February, my fbs is 90, 1 hour after, 120, 2nd hour, back to 90, but, that changes as well. In February, of 2014, on the 5th, it was horrible. I think I had eaten Lasagne, well, before, my sugars did not change much, but that night, WHAM-O I started at 80 before the meal, I forgot to take it at the one and two hour mark, but did at the 3 hour mark, it was 175, then at four hours, down to 160, then at 5 hours, back to 175. I went to bed, because by that time, it was 2 AM, but when I woke up at 8:00 and took it, it was back to 89!!!! This horrible ordeal has only happened once, but, I have gone up to 178 since, but come down to normal in 2 hours. I don’t know if I was extra stressed that day or what, I am under tons of it, my marriage is not good, my dear dad died 2 years ago and my very best friend died 7 months ago, I live in a strange country, I am from America, but moved to New Zealand last year, and I am soooo unhappy. Anyway, what does confuse me is why the daily differences, even though I may Continue reading >>

Video: What Eating “high-fat” Or “keto” Does To Your Blood Sugar

Video: What Eating “high-fat” Or “keto” Does To Your Blood Sugar

What happens to your blood sugar when you eat fat? The steps you need to stabilize your blood sugar and increase your fat-burning hormones (by following a Fat Fueled, keto eating style). Up until I found keto (high-fat, low-carb living) I was in the “eat every 2-3 hours in order to control blood sugar” camp. What I didn’t know, was that the constant eating; generally of carbohydrates, was exactly what was causing my blood sugar irregularities – constant “hangry” feelings, hypoglycemia, insulin resistance, and more. After a couple of weeks of eating Fat Fueled, keto, I no longer struggled with hypoglycemia. It was as if my sugar lows just… disappeared. And I’m not the only one that’s experienced massive changes to blood sugar shortly after shifting to a Fat Fueled, keto life. I invited Dietitian Cassie on the show today to help explain exactly what happens to our blood sugar when we eat fat – the ins and outs of insulin resistance, actions that affect blood sugar, how to use carb-ups to heal insulin resistance and much more. Today’s keto video encourages us to use dietary fat as our ally, to rely on it to support balanced blood sugar, thriving hormones and a healthy body. For video transcription, scroll down. Highlights… What foods affect blood sugar How dietary fat affects your blood sugar If combining carbohydrates and fat is a good thing How fat cells are created How to get into fat-burning mode Signs and symptoms of insulin resistance and insulin sensitivity How cortisol (and a poor sleep) affects your blood sugar How carb cycling and carb refeeding can help bust through insulin resistance How to heal yourself from insulin resistance Resources… Watch the video: When to know it’s time to carb-up (and how to do it) Step-by-step guide on goin Continue reading >>

High Blood Sugar In Ketogenic Dieters! Plus A Special Surprise (hint: Genotypes And Metabolism)!

High Blood Sugar In Ketogenic Dieters! Plus A Special Surprise (hint: Genotypes And Metabolism)!

A while ago Michael and I were discussing future article topics. There are truly a plethora of avenues to go down in this area of research and there is no lack of things to research and comment on. But even though I have a couple of pretty cool MCT articles sitting around on my desk, I want an interesting topic. I want something new. Something challenging. Besides, everyone is drinking the MCT koolaid these days. It’s become passe. (Also, it upsets my stomach and I have a personal vendetta against it. So there.) What’s new? There has to be something new! Michael pointed me to one of his old articles on physiological insulin resistance as an idea. I brushed it off at first. Dismissed it as a quirk. But then I thought about it. WHY does blood glucose rise in response to a low carb diet? It truly is an interesting question. What does it say about low carb diets if they induce an almost diabetic effect on circulating glucose? Thus my research began. This short abstract confirmed that it is normal for people on low carb diets to experience a rise in blood glucose levels. Because it’s a non-open journal (shame!), there’s a one-sentence explanation given: A decrease in first-phase insulin secretion may partially contribute to the short-term LC/HFD-induced increase in postprandial plasma glucose levels. First phase insulin secretion? There’s a first phase? So… There’s more than one phase to insulin secretion? I had no idea. Call me ignorant but I had no idea until this point that there was more than one phase to insulin secretion. This article delves deeper into the signaling involved in (what I learned is called) biphasic insulin secretion. The first phase of insulin secretion lasts approximately 10 minutes, and the second phase of insulin secretion picks up afte Continue reading >>

Diabetes Forum The Global Diabetes Community Find support, ask questions and share your experiences. Join the community My diagnosis of pre-diabetes or diabetes seems to be dependent on the practice nurse or GP. However after following a "healthy" diet including fruit, veg, cereals, etc. my fasting blood glucose gradually rose to 7.7 mmol/l. I dramatically reduced my carb intake and am now on a ketogenic diet with consistent fasting levels of between 4.6 and 5.0. I would gratefully welcome your opinion as to whether I am diabetic or not? FBG isn't that great an indicator of whether you have Type 2 or not as it represents your blood sugar levels at that precise moment in time. Did you have an HbA1c test as well? That will let you know your average blood sugar levels for the past 2-3 months (we all vary) and is usually used for diagnosis. Your keto diet will be great for keeping your levels down and so you are certainly controlling your condition. Probably not cured but certainly in remission. Hope that helps. At this point, I think the label doesn't matter, as long as you stick to a keto diet. The label comes from western medicine, which is based on western issues, like the western diet in particular. BUT, either way, you're at risk for diabetes eating a carb-heavy diet. Thanks guys, I very much appreciate your comments. Type 1 now. Still love my keto diet in all my stages of D. I teuely believe I held off the inevitable insulin LADA by a keto diet. kokhongw I reversed my Type 2 Well-Known Member That you have had elevated fasting level typically means that you have insulin resistance and loss in beta cells function/mass, but not enough to be considered clinically diabetic.

Fasting Physiology – Part Ii

Fasting Physiology – Part Ii

There are many misconceptions about fasting. It is useful to review the physiology of what happens to our body when we eat nothing. Physiology Glucose and fat are the body’s main sources of energy. If glucose is not available, then the body will adjust by using fat, without any detrimental health effects. This is simply a natural part of life. Periods of low food availability have always been a part of human history. Mechanisms have evolved to adapt to this fact of Paleolithic life. The transition from the fed state to the fasted state occurs in several stages. Feeding – During meals, insulin levels are raised. This allows uptake of glucose into tissues such as the muscle or brain to be used directly for energy. Excess glucose is stored as glycogen in the liver. The post-absorptive phase – 6-24 hours after beginning fasting. Insulin levels start to fall. Breakdown of glycogen releases glucose for energy. Glycogen stores last for roughly 24 hours. Gluconeogenesis – 24 hours to 2 days – The liver manufactures new glucose from amino acids in a process called “gluconeogenesis”. Literally, this is translated as “making new glucose”. In non-diabetic persons, glucose levels fall but stay within the normal range. Ketosis – 2-3 days after beginning fasting – The low levels of insulin reached during fasting stimulate lipolysis, the breakdown of fat for energy. The storage form of fat, known as triglycerides, is broken into the glycerol backbone and three fatty acid chains. Glycerol is used for gluconeogenesis. Fatty acids may be used for directly for energy by many tissues in the body, but not the brain. Ketone bodies, capable of crossing the blood-brain barrier, are produced from fatty acids for use by the brain. After four days of fasting, approximately 75 Continue reading >>

Is Your Fasting Blood Glucose Higher On Low Carb Or Keto? Five Things To Know

Is Your Fasting Blood Glucose Higher On Low Carb Or Keto? Five Things To Know

This past spring, after 18 months of great success on the keto diet, I tested my fasting blood sugar on my home glucose monitor for the first time in many months. The result shocked me. I had purchased the device, which also tests ketones, when I was diagnosed with pre-diabetes in the fall of 2015. As I embarked on low-carb keto eating, I tested my blood regularly. Soon my fasting blood sugar was once again in the healthy range. I was in optimal ketosis day after day. Not only that, I lost 10 lbs (5 kg) and felt fantastic — full of energy with no hunger or cravings. Before long I could predict the meter’s results based on what I was eating or doing. I put the meter away and got on with my happy, healthy keto life. When my doctor ordered some lab tests this spring, I brought the meter out again. While I had no health complaints, excellent blood pressure and stable weight, she wanted to see how my cholesterol, lipids, HbA1c, and fasting glucose were doing on my keto diet — and I was curious, too. To check the accuracy of my meter against the lab results, on the morning of the test I sat in my car outside the clinic at 7:30 am, and pricked my finger. I was expecting to see a lovely fasting blood glucose (FBG) of 4.7 or 4.8 mmol/l (85 mg/dl). It was 5.8! (103 mg/dl). What? I bailed on the tests and drove home — I didn’t want my doctor warning me I was pre-diabetic again when I had no explanation for that higher result. The next morning I tested again: 5.9! (104). Huh??? For the next two weeks I tested every morning. No matter what I did, my FBG would be in 5.7 to 6.0 (102 to 106 mg/dl), the pre-diabetic range again. One morning after a restless sleep it was even 6.2 mmol/l (113 mg/dl). But my ketones were still reading an optimal 1.5-2.5 mmol/l. I was still burnin Continue reading >>

High Fasting Blood Sugar On Keto?

High Fasting Blood Sugar On Keto?

The more I coach people through a ketogenic lifestyle, the more I become familiar with small nuances that can affect different peoples experience. For example, there are a number of people who experience high fasting blood sugar upon waking in the morning. These individuals would express that they were following a ketogenic diet and were in a fasted state so it doesnt make sense to have elevated blood sugar. What you are going to find out in this article is that this effect may actually be much more normal than you think. In fact, it may not even be an issue. That being said, for some people it may actually be a sign of something undesirable going on with their metabolism. This article will help you troubleshoot what is likely to be causing your high fasting blood sugar. When someone has elevated fasting blood sugar and is NOT following a ketogenic lifestyle, it is likely that they are suffering from insulin resistance. Insulin resistance is characteristic of pre-diabetes and diabetes , as well as metabolic syndrome. This is when your cells stop listening to insulins signals to let glucose into the cell and instead allow glucose to continue circulating in the blood. This is often due to a high sugar diet that constantly bombards insulin receptors to the point where they become desensitized. Think Little Boy Who Cried Wolf, but with your cells. This is called pathologic insulin resistance as it is considered a disorder and increases your risk of many different diseases . In diabetics, there are 2 common ways that high fasting morning blood sugar arises. The first reason is the Dawn Phenomenon and this impacts individuals who are following a ketogenic lifestyle as well. Overnight as we sleep between the hours of 2-8am a slurry of hormones including cortisol, growth hormo Continue reading >>

The Ketogenic Diet And Insulin Resistance

The Ketogenic Diet And Insulin Resistance

We recently touched on how you can use the ketogenic diet to control symptoms of diabetes such as elevated glucose and triglycerides. In this article, we examine research showing the impact that the ketogenic diet has on levels of the hormone insulin, a key regulator of blood sugar in the body. What is Insulin’s Role in the Body? Before we look at the research, we need to know our main players. Insulin is a protein-based hormone produced by beta-cells located in the pancreas. The pancreas, which is located under the stomach, also produces enzymes that aid with digestion. Insulin’s primary purpose is to regulate the metabolism of fats and carbohydrates. The digestive system breaks down carbohydrates, such as sugars and starches, into a molecule called glucose. This compound can be used by cells to produce energy through a process called cellular respiration. Insulin allows cells in the body absorb glucose, ultimately lowering levels of glucose in the blood stream. After a meal is consumed, blood glucose levels increase and the pancreas responds by releasing insulin into the blood. Insulin assists fat, liver, and muscle cells absorb glucose from the blood, resulting in lower levels of blood glucose. Insulin stimulates liver and muscle tissues to store excess glucose as a molecule called glycogen and also reduces glucose production by the liver. When blood sugar is low, the hormone glucagon (produced by alpha-cells in the pancreas) stimulate cells to break down glycogen into glucose that is subsequently released into the blood stream. In healthy people who do not have type II diabetes, these functions allow levels of blood glucose and insulin to stay in a normal range. What Is Insulin Resistance and Why Is It a Problem? Unfortunately, for many Americans and other peopl Continue reading >>

Blood Sugar Levels In Ketosis: Part Ii

Blood Sugar Levels In Ketosis: Part Ii

Welcome to Keto Sister. Last week’s post explained what happens to blood glucose levels as a result of eating a ketogenic diet. In sum, blood glucose (also known as blood sugar) decreases and is replaced in large part by a new fuel source, ketone bodies. Humans are always being fueled by two energy substrates: glucose and fatty acids. A person who eats a high carbohydrate diet burns more glucose as fuel, and a person who eats a high fat diet burns more fat as fuel. However, there is never a time at which a person stops burning one or the other. The implication for someone eating a low carb diet is that the body never replaces all glucose utilization with ketone bodies. Instead, the body reduces its glucose needs to the bare minimum and then it makes any needed glucose not taken in through the diet through gluconeogenesis. This is the normal, healthy process of fueling the body in the absence of dietary glucose. Elevated Blood Glucose There are many benefits of ketogenic nutrition when a ketogenic diet is implemented correctly. One of the benefits of eating low carb is blood glucose control, and this can be a big benefit to those who struggle with type 2 diabetes and obesity. As I mentioned last week, ideal blood glucose levels are between 81 and 109 milligrams per deciliter (see this post for details). However, it is a common occurrence for those following a very low carb diet to have elevated blood glucose levels. I mentioned the first two causes last week, but there is a third that is rarely discussed by those in the low carb arena. Admittedly, these concepts are not well understood by most people. Nevertheless, here is what we know about elevated blood sugar levels in ketosis: Physiological Insulin Resistance (PhIR). Eating a low carb diet in and of itself can indu Continue reading >>

What Is A Glucose Ketone Index And Why You Should Care

What Is A Glucose Ketone Index And Why You Should Care

Having high levels of ketones doesn’t mean you’re automatically getting all of the benefits. Luckily, research shows us that there’s an easy way to know if you’re in prime therapeutic mode so you can be confident you’re getting the best results. Ketosis can already be complicated if you don’t test and figure out what kicks you out. Once you start getting serious about ketosis and tracking ketone levels, you can usually step things up a notch with a simple calculation. You can become more specific with what works for you as an individual. How you do that is by calculating your glucose ketone index. The Glucose Ketone Index, or the GKI, is a ratio that researcher Dr. Thomas Seyfried has been using in his studies relating to both fasting and the ketogenic diet. There’s nothing fancy to this index, it is just a ratio of blood glucose levels to blood ketone levels. Having high level of ketones are great and all, but if you also have a super high level of blood glucose, you’re really just spinning your wheels and not getting any benefits of ketosis. And the real key here is to make sure that the ratio between glucose and ketone levels is as low as possible. If you’ve been following along, you’ll note I was pretty big on this glucose ketone index on my recent my four day fast and it actually dictated the time spent in the fast. But why did I care about this ratio, and why should you care? Why Should You Care? Dr. Seyfried does a lot of his research in the realm of cancer treatment and has noticed increasingly impressive therapeutic outcomes with the lower the glucose ketone index ratio gets. Dr. Seyfried claims that a GKI of lower than 1.0 is prime therapy for patients with cancer, and he has plenty of data to back this up. The graph above shows how tumor g Continue reading >>

How You Can Have High Blood Sugar Without Carbs

How You Can Have High Blood Sugar Without Carbs

How You Can Have High Blood Sugar Without Carbs Can you have high blood sugar without carbs? Well, its important to look at common beliefs about high blood sugar first. High blood sugar is bad. Carbohydrates raise blood sugar. Therefore carbohydrates are bad. The theory is simple, and yet incredibly flawed. The truth is, you can have chronically high blood sugar even while religiously avoiding every starch and sugar in sight. Low-carb forums are littered with posts asking a very relevant question: Why is my blood sugar so high when Im not eating any carbs? The answer is simple, yet often overlooked. The Hormone that Raises Blood Sugar: No Carbohydrates Required If the body were an engine, glucose would be its fuel. Most people think glucose only comes from carbohydrates (sugar and starch), but protein can also be turned into glucose when there arent enough carbs around to do the job. This is called gluconeogenesis, and its performed by one of the major stress hormones cortisol. When you have high cortisol levels (from diet, lifestyle, etc.), the cortisol rapidly breaks down protein into glucose, which can raise blood sugar levels considerably. For some folks, this results in chronically high blood sugareven if they are on a low-carb diet. The trouble is, cortisol isnt just breaking down the protein you eat. Its doing something far more destructive. The body is quite a smart machine, and it has no problem taking detours to get energy if necessary. If your body isnt getting the energy it needs from your diet, it has a back-up source: its own tissue. It sounds kind of cannibalistic, eating your own lean body tissue for energy. I mean, I seriously doubt any one of you would relish cutting off a chunk of your leg for dinner. I know I wouldnt. But every time your body uses c Continue reading >>

Glucose Numbers And Ketogenic Diet

Glucose Numbers And Ketogenic Diet

GLUCOSE NUMBERS and KETOGENIC DIET When eating a ketogenic diet, the most exposure to carbohydrates is overnight especially towards morning as the liver produces glucose to keep your brain fueled and to prepare you for getting up. Therefore, if you are eating a very ketogenic diet, the blood ketones go up during the day as you burn more fat for fuel (as apposed to a high carb diet where the opposite happens). Something to consider, a ketogenic diet rapidly induces insulin resistance. This is a normal physiological response to carb restriction. Carb restriction drops insulin levels. Low insulin levels activate hormone sensitive lipase. This breaks down fatty tissue into ketone bodies (blood ketones). Your muscles prefer to run on ketones and so they become insulin resistant leaving the glucose in your blood for other cells (like the brain). However, while muscles are in “refusal mode” for glucose any glucose put into your bloodstream, from food or gluconeogenesis (blood glucose made from protein or other tissues), will rapidly spike blood glucose. This is fine if you stick to LC in your eating. It also means that if you take an oral glucose tolerance test you will fail and be labelled diabetic. In fact, even a single high fat meal can do this, extending insulin resistance in to the next day. So if you are getting a blood glucose test, you can increase your carbs to 150 grams a day for 3 days prior and your blood glucose levels will show normal according to the standards. Otherwise, you can look at a better marker for metabolic syndrome which is you HbA1c levels. If these are low (5.5 or less is what a doctor will define as low diabetes risk, 5 or less is ideal), it doesn’t matter what your fasting blood glucose levels are. Also an interesting note, when mice in a r Continue reading >>

How To Lower Your Blood Sugar Naturally

How To Lower Your Blood Sugar Naturally

Processed foods like cookies, cakes, and candy (and even starchy plant foods like rice, beans, and potatoes) can cause rapid increases in blood sugar levels. After one meal containing these foods, blood sugar can get so high that insulin can’t keep up. Side effects like fatigue, blurred vision, headaches, trouble concentrating, and frequent urination can result. If you consume high-carbohydrate foods every day, you increase your risk of type 2 diabetes — the medical diagnosis for having chronically high blood sugar levels that are caused by diet and lifestyle. (This is different from type 1 diabetes — a condition where the body produces little to no insulin.) Over 422 million people have diabetes worldwide, and their high blood sugar levels are destroying their bodies. To know if your blood sugar levels are chronically high, many doctors will check your A1C levels. A1C stands for glycated hemoglobin, which is formed when blood sugar attaches to hemoglobin (the oxygen-carrying protein in red blood cells). A1C tests measure the percentage of your hemoglobin that has blood sugar attached to it. If blood sugar levels have been high for the past 3 months, then more hemoglobin will be glycated. Thus, A1C testing provides an accurate measurement of how high your blood sugar has been over the past two to three months. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates pre-diabetes. Below 5.7 is considered normal. Earlier in this article, we explored how you can raise your blood sugar. Just eat cookies, cakes, rice, potatoes, and other high-carbohydrate foods, and you will be on the fast track toward diabetes. Following this logic, won’t eating fewer carbohydrates lower your blood sug Continue reading >>

The High Blood Glucose Dilemma On Low Carb (lc) Diets

The High Blood Glucose Dilemma On Low Carb (lc) Diets

If you are on a ketogenic or very low carb (VLC) diet (e.g. with 50-100gr carb/day and/or eating ketone producing MCT oils such as coconut oil), you may have a dilemma of having high Blood Glucose (BG) despite eating LC: If you are keto adapted, that is, your body is using ketones and even though you have sufficient insulin (say >5 microU/ml) your body tries to keep your BG higher than necessary, e.g. above 100-110 mg/dl. That is your BG set-point is always high. If you try to lower the set-point to say 80s, by water Intermittent Fasting (IF), then your body starts to convert your muscles into glucose to keep its high BG set-point. So, you may have a slightly lower BG, but you lose some muscle mass. Having a high set-point has many other problems, e.g. if you eat something with a little bit more carb, say a small fruit, your BG shoots up to 130s and stays there for hours. This may be due to something called "Physiological Insulin Resistance (PhIR) by Petro Dobromylskyj. He wrote many good articles about it -???thanks Petro--in his blog Hyperlipid. Apparently, PhIR is a normal reaction of the body and quite different from Pathological Insulin Resistance (PaIR). It seems that the main difference between PhIR and PaIR is that insulin is at a normal level in the former and abnormally high in the latter. (PaIR is obviously type2 diabetes.) If I understand correctly, PhIR is kind of IR only in the muscle tissue, that is only the muscles do not react to insulin and NOT use glucose even though it is available. However, if you are eating too much protein, the liver may also be considered IR, because it tries to keep the BG high by converting proteins to glucose, even though BG is already too high, that is, it also may not be responding to insulin. (I think working muscles can us Continue reading >>
