I'm new to this forum. I have been eating relatively low carb (60 grams) for about 4 months now. Eating this way has allowed me to keep my blood sugars in a pre-diabetic/normal range, lose weight and feel so much better! I have been keeping a food journal and although my fasting numbers had been staying in the 80's before, now I am seeing them in the high 90's/low 100's every morning and throughout the day as well. Upon reviewing my journal I see that my carbs have dropped more like down to 30 or so a day ( maybe I've been a bit too compulsive about this???). Anyway, I'm wondering if anyone else has see this happen to them - is it possible I have lowered my carbs too much and have actually shot myself in the foot? Or bitten the hand that feeds me??? Is it possible that not eating enough carbs could raise my blood sugar? Sometimes before a meal comes around feel hungry and then when I check my sugar at the meal it is higher (like 110 or 120) and I don't want to eat many carbs then for fear of making it worse. Is my thinking all wrong?This last month for me has been extremely busy (lots of visitors and then a two week trip away from home.) Thanks in advance for any counsel you can give. I have spend hours reading here and have learned so much already! As a long term type 1 and on a very low carb diet I can tell you without doubt that you must measure or otherwise limit the proteins, fats, and green vegtables taken in. That was the biggest surprise to me. I need to take a bolus of insulin with everything I eat to keep the sugars level. If I eat an extra helping of salad I will need to ca Continue reading >>
How Low Is Low Carb?
Many agree: People with diabetes should eat a low-carb diet. Last week we looked at what “carbs” are. But what is meant by “low?” How much carbohydrate should you eat? The Dietary Guidelines for Americans, 2010, (PDF) recommend that healthy people get 50–65% of their calories from carbohydrates. A study posted on the American Diabetes Association (ADA) Web site agrees. For a woman eating a below-average 2,000 calories a day, 50–65% would be 250–325 grams of carb a day. The Dietary Guidelines call for “a balanced diet that includes six one-ounce (28.3 g) servings of grain foods each day.” This would mean 170 grams of carbohydrate from grains alone each day. And the average American diet includes many other carb sources. Most men eat closer to 3,000 calories a day, so their numbers would be higher. Sixty percent of 3,000 would be 1,800 calories, equivalent to 450 grams of carbohydrate each day. Anything less than the recommended range is sometimes considered “low-carb.” Most popular low-carb diets, like Atkins, South Beach, Zone, and Protein Power, are much lower, from 45% of calories down to 5%. Many diabetes experts recommend somewhat lower carb intakes than ADA does. On our site, dietitian Jacquie Craig wrote, “Most people need between 30–75 grams of carbohydrate per meal and 15–30 grams for snacks.” So that sounds like between 120 and 300 grams a day. Dr. Richard Bernstein, an MD with Type 1 diabetes and a long-time advocate of the low-carb approach to diabetes, suggests much lower intakes. He says eat 6 grams of carbs at breakfast, and snacks, 12 grams each at lunch and dinner. So that would be about 40 grams of carbs per day. If 12 grams per meal sounds like a small amount, it is. It’s about the amount in an average slice of bread. An Continue reading >>
Too Few Carbs = High Blood Sugar
LowCarbSite.com is a community forum dedicated to low carb and Atkins diet. To participate in the discussions or get full access, please register , the registration is completely free and takes less than one minute. Here is a question I have for those of you more familiar with diabetes then I am. I have a friend who is diabetic, takes a generic glucophage type drug, and has been advised that she should eat at least 45 g of carbs at each meal. Now, when she eats fewer carbs, it seems her blood sugar goes really high. This seems strange to me. Can someone help me understand how that works? Metformin and low-carb work wonders for me. It also seems to be the treatment of choice at the PCOS forums I frequent. I can't understand the results your friend is seeing Bliss but I'm IR, not yet diabetic. I was told metformin works by sensitising your body to it's insulin. This should cause the carbs ingested to be better utilised. I don't see how eating less sugar makes more sugar in the blood. I've been wrongly advised in the past to eat a certain amount of carbs but that was to ensure my sugar didn't drop too low since I was taking meds, not that it would go too high if I didn't eat enough. :S[/b] I've had another think about it Bliss and it just seems wrong. The only thing I can think is that when she ate less carbs they were higher GI or that she ate less protein with the smaller meal. Protein would have slowed down the carb burning. this is how I understand insulin levels. Most of us are insulin resistant - our bodies produce too much insulin when we eat carbs, which then turns to fat. And so we stop eating carbs and lose weight. Once we have developed diabetes our bodies stop producing insulin altogether and so we must take insulin in a pill or intravenous form. I would say t Continue reading >>
Carbohydrates And Blood Sugar
When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage. As cells absorb blood sugar, levels in the bloodstream begin to fall. When this happens, the pancreas start making glucagon, a hormone that signals the liver to start releasing stored sugar. This interplay of insulin and glucagon ensure that cells throughout the body, and especially in the brain, have a steady supply of blood sugar. Carbohydrate metabolism is important in the development of type 2 diabetes, which occurs when the body can’t make enough insulin or can’t properly use the insulin it makes. Type 2 diabetes usually develops gradually over a number of years, beginning when muscle and other cells stop responding to insulin. This condition, known as insulin resistance, causes blood sugar and insulin levels to stay high long after eating. Over time, the heavy demands made on the insulin-making cells wears them out, and insulin production eventually stops. Glycemic index In the past, carbohydrates were commonly classified as being either “simple” or “complex,” and described as follows: Simple carbohydrates: These carbohydrates are composed of sugars (such as fructose and glucose) which have simple chemical structures composed of only one sugar (monosaccharides) or two sugars (disaccharides). Simple carbohydrates are easily and quickly utilized for energy by the body because of their simple chemical structure, often leading to a faster rise in blood sugar and insulin secretion from the pancreas – which can have negative health effects. Complex carbohydrates: These carbohydrates have mo Continue reading >>
A Guide To Healthy Low-carb Eating With Diabetes
Diabetes is a chronic disease that has reached epidemic proportions. It currently affects over 400 million people worldwide (1). Although diabetes is a complicated disease, maintaining good blood sugar control can greatly reduce the risk of complications (2, 3). One of the ways to achieve better blood sugar levels is to follow a low-carb diet. This article provides a detailed overview of low-carb diets for managing diabetes. If you have diabetes, your body cannot process carbohydrates effectively. Normally, when you eat carbs, they are broken down into small units of glucose, which end up as blood sugar. When blood sugar levels go up, the pancreas responds by producing the hormone insulin. This hormone allows the blood sugar to enter cells. In healthy people, blood sugar levels remain within a narrow range throughout the day. In diabetes, however, this system doesn't work the way it is supposed to. This is a big problem, because having both too high and too low blood sugar levels can cause severe harm. There are several types of diabetes, but the two most common ones are type 1 and type 2 diabetes. Both of these conditions can be diagnosed at any age. In type 1 diabetes, an autoimmune process destroys the insulin-producing beta cells in the pancreas. Diabetics must inject insulin several times a day to ensure that glucose gets into the cells and stays at a healthy level in the bloodstream (4). In type 2 diabetes, the beta cells at first produce enough insulin, but the body's cells are resistant to its action, so blood sugar remains high. To compensate, the pancreas produces more insulin, attempting to bring blood sugar down. Over time, the beta cells lose their ability to produce enough insulin (5). Of the three nutrients -- protein, carbs and fat -- carbs have the grea Continue reading >>
Healthy Carbs For Diabetes
1 / 9 Making the Best Carb Choices for Diabetes "When you say 'carbohydrate,' most people think of sugar," says Meredith Nguyen, RD, a registered dietitian and certified diabetes educator at the Methodist Charlton Medical Center Diabetes Self-Management Program in Dallas. But that's only half the story. Carbohydrates are also starches and valuable fiber, which are found in many nutrient-rich foods that should be part of a diabetes diet. Sugar is the basic building block that, depending on how it's organized, creates either starches or fiber. You need about 135 grams of carbohydrates every day, spread fairly evenly throughout your meals. Instead of trying to avoid carbs completely, practice planning your diabetes diet with everything in moderation. "There's nothing you can't have," Nguyen says. "The catch is that you might not like the portion size or frequency." Use this list of healthy carbohydrates to help you stay balanced. Continue reading >>
Why Low-carb Diets Aren’t The Answer
What raises blood sugar? The simple answer is carbohydrates. So why not just yank them out of your diet like weeds in your garden? Why not quash blood sugar by swearing off bread, pasta, rice, and cereal? Been there, done that. The low-carb craze is on the downswing, and that’s a good thing because over the long haul, very low carb diets simply aren’t good for you, as you’ll discover in this chapter. That doesn’t mean it’s not smart to cut back on carbs—but don’t go crazy. When low-carb diets first became popular, they seemed to be a breath of fresh air after the low-fat (and high-carb) diets that preceded them. Remember low-fat cookies, lowfat snack cakes, and low-fat everything else? With low-carb diets, suddenly people could load up on bacon and still lose weight as long as they were willing to eat hamburgers without buns and pretty much give up sandwiches and spaghetti. People were amazed at how effective these diets could be. Weight loss could happen very quickly, sometimes within days. And amazingly, it often seemed to come with added health benefits, including lower cholesterol, blood pressure, and triglycerides (blood fats linked to heart attacks.) The most extreme kind of low-carb diet was pioneered by the late Robert Atkins, M.D., whose first book, Dr. Atkins’ Diet Revolution, came out in 1972. It promised quick and long-lasting weight loss and prevention of chronic disease, all while allowing high-fat steak and ice cream. Since then, other, more moderate low-carb diets have allowed small amounts of carbohydrate-rich foods, but they still cut out most grains as well as starchy vegetables and even fruit. The Downsides of These Diets The Atkins diet and the many other low-carb diets that followed in its footsteps have turned out to be less effect Continue reading >>
Carb Controversy: Why Low-carb Diets Have Got It All Wrong.
Ask almost anyone what they need to do to lose a few pounds, and they’ll probably say: “Cut back on the carbs.” As a nutrition coach, I’ve heard it hundreds of times. While the low carb movement has waxed and waned in popularity since the Atkins revival of the late 90s and early 2000s, most folks now assume that carbohydrates are inherently fattening. Health-conscious diners order bunless hamburgers, skip the baked potato side dish, and send the bread basket back to the kitchen. (Or don’t, and feel guilty about it.) In the past few years, I’ll bet you’ve heard (or thought) at least one of the following: Carbs spike your blood sugar and insulin, which slathers on the body fat. Carbs, especially sugar and grains, cause inflammation. Carbs are not an essential part of the diet like fat and protein. Seems simple and logical. Which is the problem. These simplistic statements about “good foods” and “bad foods” ignore biological complexity and the bigger picture. Let’s look closer. Do carbs increase insulin levels? Yes, they do. Does increased insulin after meals lead to fat gain? No. (Insulin’s actually a satiety hormone — in other words, it makes you feel full — so the idea that on its own it leads to fat gain doesn’t make sense.) Are carbs really inflammatory? That depends. Are we talking about processed corn syrup? Probably. But if we’re talking about whole grains, not really. Are carbs less important than protein, fat, and the many micronutrients that contribute to our health? Well, if you’re talking about processed carbs, the answer is a resounding yes. But if you’re talking about whole, minimally processed carbs, that’s a different story. Can a low-carb diet work to help people lose weight? Of course it can. Is it because it is lo Continue reading >>
How Do Low-carb Diets Affect Blood Glucose Levels?
Low-carb diets are all about balancing blood sugar (blood glucose) levels. Beyond weight loss, we eat low-carb diets to keep our blood sugar normal and stable. To fully understand the connection, it's helpful to first familiarize yourself with how the body processes blood sugar in a normal state and even explore how that changes when there's a problem, such as in diabetics. What Do Carbohydrates Have to Do With Blood Glucose? Carbohydrates have everything to with blood glucose. All foods with carbohydrate -- whether rice, jelly beans, or watermelon -- break down to simple sugars in our bodies turning into glucose through metabolic processes. This process is what causes our blood glucose to rise. The carbohydrate in most starchy foods (potatoes, bread) is simply a collection of long chains of glucose, which break down quickly and raise blood sugar . What Do Our Bodies Do When Blood Sugar is High? When our blood sugar goes up, our body responds by secreting insulin to stabilize it. The sugar is then taken out of the blood and converted into fat; insulin's primary function is facilitating the storage of extra sugar in the blood as fat. Diabetics are unable to balance blood sugar when the process of converting food to energy takes place. When sugar levels are high, the ability of cells in the pancreas to make insulin goes down. The pancreas overcompensates for this lack of insulin and insulin levels stay high, as does blood sugar. Over time, the pancreas is permanently damaged and other bodily functions are affected such as hardened blood vessels, among other ailments. What are the Problems with Blood Sugar Going Up? However, for many people, this metabolic process works fine. Sometimes, though, people reach a point in their lives when it goes awry (or it doesn't work well Continue reading >>
Low Carb Vs. High Carb - My Surprising 24-day Diabetes Diet Battle
Twitter summary: What I learned from doubling my carb intake: the same average blood sugar, but four times as much hypoglycemia, more work, stress, & danger. As a teenager, I ate a high carb diet that included lots of Goldfish crackers, white sandwich bread, pasta, and white potatoes. It was tasty, but it put my blood sugars on a wild roller coaster every single day. Things turned around in college when I learned about nutrition, got on CGM, and spent time with health conscious friends. I soon realized that eating less than 30 grams of carbs at one time was a complete gamechanger. I’ve stuck with that approach ever since. But is this lower carb method actually better for my blood sugars, or have I just been fooling myself? To find out, I took on a somewhat terrifying self-tracking experiment: 12 days of my usual, lower-carb diet, which averaged 146 grams of carbs per day (21% of daily calories). My carbs were primarily from nuts, seeds, vegetables, and a bit of fruit. 12 days of a higher-carb, high whole-grain diet, which averaged 313 grams of carbs per day (43% of my daily calories). My sources of carbs were NOT junk food: plain oatmeal, whole wheat bread, quinoa, wild rice, and fruit. Neither of these was unrealistic. My lower-carb diet was nowhere near Atkins level (20 grams per day), and the higher-carb diet was consistent with the “average” 45% carb diet in people with diabetes (according to ADA). Even though this was a one-person (n=1) experiment, I wanted to be as scientific and fair as possible: eating whole, unprocessed foods in both periods; counting and tracking every single gram of carbohydrate (LoseIt! app); wearing CGM 24/7 and downloading the glucose data to document what happened (Dexcom G5 and Clarity); taking insulin before meals (5-15 minutes pr Continue reading >>
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 >>

Dear Mark: Does Eating A Low Carb Diet Cause Insulin Resistance?
157 Comments Despite all the success you might have had with the Primal way of life, doubts can still nag at you. Maybe it’s something you read, or something someone said to you, or a disapproving glance or offhand comment from a person you otherwise respect, but it’s pretty common when you’re doing something, like giving up grains, avoiding processed food, or eating animal fat, that challenges deeply-and-widely held beliefs about health and wellness. It doesn’t really even matter that you’re losing weight or seem to be thriving; you may still have questions. That’s healthy and smart, and it’s totally natural. A question I’ve been getting of late is the effect of reducing carb intake on insulin sensitivity. It’s often bandied about that going low carb is good for folks with insulin resistance, but it’s also said that low carb can worsen insulin resistance. Are both true and, if so, how do they all jibe together? That’s what the reader was wondering with this week’s question: Hi Mark, I’ve been Primal for a few months now and love it. Lowering my carbs and upping my animal fat helped me lose weight and gain tons of energy (not too shabby for a middle-aged guy!). However, I’m a little worried. I’ve heard that low carb diets can increase insulin resistance. Even though I’ve done well and feel great, should I be worried about insulin resistance? Do I need to increase my carb intake? I always thought low carb Primal was supposed to improve insulin function. Vince Going Primal usually does improve insulin sensitivity, both directly and in a roundabout way. It improves directly because you lose weight, you reduce your intake of inflammatory foods, you lower systemic inflammation (by getting some sun, smart exercise, omega-3s, and reducing or dea Continue reading >>
Will Low-carb Diets Cause Blood Sugar Levels To Drop?
Video of the Day If you're accustomed to eating a very high-carb diet and suddenly switch to a very low-carb diet, you could experience rather dramatic drops in your blood sugar during the first few days or weeks of your transition. This low blood sugar can cause notably uncomfortable side effects and intense cravings. Carbs and Blood Sugar Your body converts consumed carbohydrates into glucose, a type of sugar. When the glucose enters your bloodstream, it leads to an increase in your blood sugar level. The pancreas produces insulin in response to spikes in blood sugar, which helps your body store the sugar for energy. This insulin release subsides when your cells absorb the sugar and your levels stabilize. In a healthy body, the surge of blood sugar and insulin is relatively moderate and keeps you evenly motoring through your day. When you eat lots of carbohydrates, your body's blood sugar remains consistently high and your system constantly pumps out insulin. This chronic elevation of blood sugar and release of insulin causes inflammation, an increase in fat storage and an inability to burn stored fat. Chronically high blood sugar levels increase your risk of disease, including heart disease and type 2 diabetes. You crave carbohydrates regularly for energy, because your body isn't efficient at using stored fat for fuel. How a Low-Carb Diet Impacts Blood Sugar If you regularly consume a large amount of carbohydrates, especially refined ones like white bread and soda, you may experience a notable drop in blood sugar when you drastically reduce your carb intake. In the first week of carb reduction, your body will seek to maintain your high sugar intake. You'll crave carbohydrates and may even feel weak because your body hasn't yet become efficient at burning fat for fuel Continue reading >>
Is Low-carb Eating Really Better For Blood Sugar?
A review of popular low-carbohydrate diets finds that while restricting carbs can reduce blood sugar in the short run, evidence in support of long-term benefits is lacking. While very low carbohydrate diets (LCD) promise to cut blood sugars, a review of popular LCDs finds that while very low-carb eating can reduce blood sugar in the short run, little evidence exists to show long-term benefits. The study, published online in the Journal of the American Osteopathic Association, reports that while LCDs may be “slightly better than low fat diets for weight and triglycerides management” they are “not superior for the management of blood glucose, blood pressure, or cholesterol levels.” However, researchers note that physicians should be aware that “available evidence for LCDs is limited because of variable definitions, lack of long-term studies, and lack of patient adherence.” Diets considered ranged from very low carb—less than 20 to 60 grams per day—to less restrictive diets that averaged about 130 grams per day. The American Diabetes Association says diets should be tailored to individual needs, but recommends starting at 45-60 grams of carbohydrates per meal. “Patients can likely follow a version of the low carbohydrate diet for longer than the studies suggest, but we don’t know the health effects of a very low carbohydrate ketogenic diet of less than 20 grams of carbs per day,” says Heather Fields, MD, an author of the study and a doctor of integrative medicine at the Mayo Clinic in Phoenix, Arizona. “With so few people adhering to a truly ketogenic diet long term [more than a year], we will likely never be able to study the health effects in a meaningful way.” Dr. Fields finds that if type 2 patients have not had success with a plant-based, who Continue reading >>
How Many Carbs Should A Person With Diabetes Eat?
Knowing how many carbs you should consume isn't as tricky as you may think. By Franziska Spritzler, RD, CDE Figuring out how many carbs to eat when you have diabetes can seem confusing. Meal plans created by the American Diabetes Association (ADA) provide about 45% of calories from carbs. This includes 45–60 grams per meal and 10–25 grams per snack, totaling about 135–230 grams of carbs per day. However, a growing number of experts believe people with diabetes should be eating far fewer carbs than this. In fact, many recommend fewer carbs per day than what the ADA allows per meal. This article takes a look at the research supporting low-carb diets for diabetics and provides guidance for determining optimal carb intake. What Are Diabetes and Prediabetes? Glucose, or blood sugar, is the main source of fuel for your body’s cells. In people with diabetes, the body’s ability to process and use blood sugar is impaired. Although there are several types of diabetes, the two most common forms are type 1 and type 2 diabetes. Type 1 Diabetes In type 1 diabetes, the pancreas is unable to produce insulin, a hormone that allows sugar from the bloodstream to enter the body’s cells. Instead, insulin must be injected to ensure that sugar enters cells. Type 1 diabetes develops because of an autoimmune process in which the body attacks its own insulin-producing cells, which are called beta cells. This disease is usually diagnosed in children, but it can start at any age, even in late adulthood. Type 2 Diabetes Type 2 diabetes is more common, accounting for about 90% of people with diabetes. Like type 1 diabetes, it can develop in both adults and children. However, it isn’t as common in children and typically occurs in people who are overweight or obese. In this form of the d Continue reading >>
