Carbohydrates: How Low Is Too Low?

Carbohydrates: How Low Is Too Low?

The term "low carb" is not easily defined. Low as compared to what? The Recommended Dietary Allowance (RDA) for minimum carbohydrate intake, as set by the Institute of Medicine's Food and Nutrition Board, is 130 grams per day. This is the level which dietitians are taught to instruct people never to go below "in order to maintain brain function." This recommendation is based on the central nervous system's daily requirement for about 130 grams of glucose (NOT carbohydrates). Further confusing the issue, the Reference Daily Intake (RDI) for carbohydrate (also set by the Food and Nutrition Board) "to meet the needs of 97-98% of healthy individuals" is 300 grams for a diet containing 2000 calories and 375 grams for a 2500- calorie diet (You can see find these numbers in the Daily Values section on any nutrition facts label). Why the disparity? Because the Board recommends that carbohydrates make up 45-65% of caloric intake. For someone eating 2000 calories daily, going with the average of 55% , this is 1100 calories or 275 grams of carbs. Not exactly 300 grams, but close. I'm not sure why the Board didn't set the value at 250 grams, or 45% of calories, since this would still be more than sufficient to meet people's needs and is nearly double the RDA. But for whatever reason, the RDI I is set at 300 grams. So is low carb anything below 300 grams, then? Well, few people would argue that eating 280 grams of carbs a day constitutes a low-carbohydrate diet. Most would consider less than 150 grams to be low carb, or moderately low carb at the upper limit. Of course, there's a big difference between 15 grams of carbohydrates vs. 149 grams per day. Also, are we talking about total carbs or digestible ("net") carbs, calculated by subtracting the fiber from the total carb content? S Continue reading >>

How Many Carbs Should I Eat To Prevent Ketosis?

How Many Carbs Should I Eat To Prevent Ketosis?

When you’re on a low-carb diet, your body kicks into action, breaking down fats into ketone bodies to use for energy. This increase in ketones -- called ketosis -- is a normal adaptation to cutting carbs. In fact, the switch to ketosis is why low-carb diets work. Even though you could eat enough carbs to prevent ketosis, it's important to clarify why you want to avoid it. There's nothing unhealthy about ketosis, so you may just need to correct any misinformation to make the best decision for your weight-loss goals. Video of the Day Deal With Concerns Over Ketosis Ketosis is often confused with ketoacidosis, which is unfortunate -- ketosis is normal, while ketoacidosis is a dangerous condition related to type 1 diabetes. Most people on a low-carb diet tolerate ketosis without any problems. Then after the pounds are dropped, carb intake is gradually increased so you're out of ketosis by the time you reach the maintenance phase. If you decide to stay in an induction phase longer than the low-carb plan recommends, consult your doctor to be safe. People with type 1 diabetes are at risk for developing ketoacidosis from lack of insulin. Due to the complex metabolism of diabetes, they end up with high levels of blood glucose and ketones, which upsets the body's normal acid-base balance. When that happens, ketosis becomes ketoacidosis, causing symptoms like thirst, frequent urination, dry mouth, nausea, belly pain, rapid breathing and fruity-smelling breath. If you have symptoms, contact your doctor immediately -- diabetic ketoacidosis is a medical emergency. You may be wary about ketosis because you've heard about "ketosis flu." It's not really flu, but in the first few days or weeks of a low-carb diet, some people experience headaches, dizziness, fatigue, constipation or wea Continue reading >>

Metabolic Effects Of The Very-low-carbohydrate Diets: Misunderstood

Metabolic Effects Of The Very-low-carbohydrate Diets: Misunderstood "villains" Of Human Metabolism

Go to: The Ketone Bodies are an Important Fuel The hormonal changes associated with a low carbohydrate diet include a reduction in the circulating levels of insulin along with increased levels of glucagon. This activates phosphoenolpyruvate carboxykinase, fructose 1,6-biphosphatase, and glucose 6-phosphatase and also inhibits pyruvate kinase, 6-phosphofructo-1-kinase, and glucokinase. These changes indeed favor gluconeogenesis. However, the body limits glucose utilization to reduce the need for gluconeogenesis. In the liver in the well-fed state, acetyl CoA formed during the β-oxidation of fatty acids is oxidized to CO2 and H2O in the citric acid cycle. However, when the rate of mobilization of fatty acids from adipose tissue is accelerated, as, for example, during very low carbohydrate intake, the liver converts acetyl CoA into ketone bodies: Acetoacetate and 3-hydroxybutyrate. The liver cannot utilize ketone bodies because it lacks the mitochondrial enzyme succinyl CoA:3-ketoacid CoA transferase required for activation of acetoacetate to acetoacetyl CoA [3]. Therefore, ketone bodies flow from the liver to extra-hepatic tissues (e.g., brain) for use as a fuel; this spares glucose metabolism via a mechanism similar to the sparing of glucose by oxidation of fatty acids as an alternative fuel. Indeed, the use of ketone bodies replaces most of the glucose required by the brain. Not all amino acid carbon will yield glucose; on average, 1.6 g of amino acids is required to synthesize 1 g of glucose [4]. Thus, to keep the brain supplied with glucose at rate of 110 to 120 g/day, the breakdown of 160 to 200 g of protein (close to 1 kg of muscle tissue) would be required. This is clearly undesirable, and the body limits glucose utilization to reduce the need for gluconeogenesis Continue reading >>

How To Find Your Ketogenic Diet Carb Limit

How To Find Your Ketogenic Diet Carb Limit

There is no legitimate carb limit for keto. The keto gods won’t banish you to burn in sugar hell forever if you eat an extra blueberry. The truth is that every person has a different carb limit that they should stick to so that they can trigger ketone production. This “carb limit” also changes depending on the day. Whether your body achieves ketosis or not — the main reason why you are limiting carbs in the first place — depends on many factors. Some people may be able to get into ketosis with a slightly higher carb intake while others need to restrict their carbs below 35 grams per day. So, what does this mean for you? How can you find your very own keto carb limit? Finding Your Keto Carb Limit Although everyone may need to restrict their carbs to slightly different amounts to get into and stay in ketosis, there is a carb limit that almost anyone can use to achieve results. This keto carb limit is 35 grams of total carbs and 25 grams of net carbs. (Net carbs are found by subtracting the grams of the fiber from the total grams of carbs.) If net carbs are further limited to less than 20 grams, then most people will get into ketosis even more quickly. Keeping your carbs consumption at this level and rarely going above it is a reliable way to stay in ketosis (as long as you eat the right amount of protein — more on that later). To figure out how to track your carbs and stay below the carb limit, here’s a guide you can use to keep it as simple as possible. And here is a brief list of what you should and shouldn’t eat to achieve ketosis: Do Not Eat Grains – wheat, corn, rice, cereal, etc. Sugar – honey, agave, maple syrup, etc. Fruit – apples, bananas, oranges, etc. Tubers – potato, yams, etc. Do Eat Meats – fish, beef, lamb, poultry, eggs, etc. Lea Continue reading >>

It varies per individual but a healthy individual can prevent ketosis with 100 to 120 grams of carbohydrates. How many grams of protein are recommended per day? For sedentary adults, about 0.8 grams per kilogram of body massis recommended. If, for instance, you are 70 kg, it is recommended that you have: 70 kg x 0.8 grams protein per kg per day = 56 grams protein per day However, it should be noted that this is the general rule forsedentary adults. It is widely agreed that up to 1.8 grams perkilogram of body mass are needed for active adults engaged instrength training or intense endurance training. For the averageperson, the easiest way to determine how much protein is needed itto divide their weight in half. For example, a 150 pound personwould need 75 grams of protein a day, ideally.

The Carbohydrate Needs Of Adult Females

The Carbohydrate Needs Of Adult Females

Normal Suggested Amount of Fat and Protein Intake for Women Carbohydrates are one of the main sources of energy for your body, and your brain's preferred energy source. Plant foods are the best sources for carbohydrates, of which there are three types: sugars, starches and fiber. Sugars combine to form starches, which enzymes in your body break down during digestion, and fiber, for which people lack the enzymes to break down. Not consuming enough carbohydrates could leave you feeling weak and fatigued. Adult females should consume at least 150 grams of carbohydrate per day to avoid ketosis and provide enough fuel for the central nervous system. Ketosis occurs when your body doesn't have enough glucose for fuel. This can cause symptoms including bad breath, fatigue, headaches and nausea. Very low carbohydrate intakes can also make it difficult for you to consume the required amounts of vitamins and minerals. The 2010 Dietary Guidelines for Americans recommends you get between 45 percent and 65 percent of your calories from carbohydrates. If you consume 2,000 calories per day, this means you should consume between 225 grams and 325 grams of carbohydrates each day. Most of these carbohydrates should be from nutrient-dense whole foods rather than processed foods made with sugars and refined grains. Although fiber isn't digested, it helps clean out your digestive tract and limits your risk for constipation and other digestive complaints, high blood pressure, diabetes, high cholesterol and obesity. Adult women under 51 years old should consume at least 25 grams of fiber per day, and those aged 51 or older need at least 21 grams of fiber per day, according to the National Academy of Sciences' Institute of Medicine. Consuming processed foods with a high glycemic load may incre Continue reading >>

Sort type 2 is the more common type where cells resist insulin. Cells fail to respond to insulin or the insulin amount is insufficient). This condition tends to occur as a consequence of obesity. The pancreas produces enough insulin but the cell surface receptors have lost much of their ability to recognize the insulin and don't respond. Dietary carbohydrate does not cause diabetes. Many people with this type of diabetes are obese. Obesity is clearly a factor in this type. As the incidence of obesity in the U.S. has risen in recent decades, the incidence of diabetes has followed.

The low carbohydrate diet craze to lose weight fast: Adkins, The Zone and South Beach diet, do these diets really work? The answer is yes, but how healthy are they? That is still left up to debate. There are no long term statistics on how these diets affect our health years down the road. But there is some information about what happens to your body while on these diets today. First of all, carbohydrates are natural organic substances such as sugar, starch and cellulose. They are a major source of quick energy for our bodies. Are there good and bad carbs? Well, some foods offer no nutritional benefit beyond calories, for example, sugar. So those would be listed in the bad category. Other whole grains such as whole-wheat pasta, brown rice or oatmeal, offer many vitamins, minerals, and fiber that promote health. So these would be listed in the good category. In theory, a carbohydrate raises the blood sugar, which then raises the insulin level to store that sugar in the fat cells to use later as energy. They say that a lower intake of carbohydrates at meals causes the body to use the already stored energy that is stored as fat. The initial weight loss from a low carbohydrate diet is: stored carbohydrates (glycogen) and fat. When your body burns glycogen, water is released and you lose weight. When you burn fat, you release byproducts called ketones. Your kidneys remove these byproducts through your urine. The build up of ketones can leave a person feeling fatigued and nauseated. There is new research that shows ketosis adversely affecting test performance that required higher mental processing. (Not good during finals or midterms!) Further research is needed to confirm this new information and the long term effects of putting your body into a ketotic state, even for a sho Continue reading >>

5 Most Common Low-carb Mistakes (and How To Avoid Them)

5 Most Common Low-carb Mistakes (and How To Avoid Them)

A few months ago, I read a book called The Art and Science of Low-Carbohydrate Living. The authors are two of the world's leading researchers on low-carb diets. Dr. Jeff S. Volek is a Registered Dietitian and Dr. Stephen D. Phinney is a medical doctor. These guys have performed many studies and have treated thousands of patients with a low-carb diet. According to them, there are many stumbling blocks that people tend to run into, which can lead to adverse effects and suboptimal results. To get into full-blown ketosis and reap all the metabolic benefits of low-carb, merely cutting back on the carbs isn't enough. If you haven't gotten the results you expected on a low-carb diet, then perhaps you were doing one of these 5 common mistakes. There is no clear definition of exactly what constitutes a "low carb diet." Some would call anything under 100-150 grams per day low-carb, which is definitely a lot less than the standard Western diet. A lot of people could get awesome results within this carbohydrate range, as long as they ate real, unprocessed foods. But if you want to get into ketosis, with plenty of ketoness flooding your bloodstream to supply your brain with an efficient source of energy, then this level of intake may be excessive. It could take some self experimentation to figure out your optimal range as this depends on a lot of things, but most people will need to go under 50 grams per day to get into full-blown ketosis. This doesn't leave you with many carb options except vegetables and small amounts of berries. If you want to get into ketosis and reap the full metabolic benefits of low-carb, going under 50 grams of carbs per day may be required. Protein is a very important macronutrient, which most people aren't getting enough of. It can improve satiety and incr Continue reading >>

I realize that this is highly variable, but what number of grams have you guys found to be the threshold? I suppose if you are right at the threshold, you'll be passing in and out of it, so maybe we'd want a 10g buffer or something? Personally, I'd like to stay outside of it, but only just, and am wondering what the general rule of thumb is these days. I do strength-increasing workouts and walk around a lot, but I avoid what most consider to be "exercise." 1 Worst Carb After Age 50 If you're over 50 and you eat this carb, you will never lose belly fat. HealthPlus50 I was at 3 servings of fruit a day for a while (roughly 75g of carbs) but feel like I might be able to go a little lower.

Ketogenic Diet Foods To Avoid: 108 Foods That’ll Slow Your Fat Loss

Ketogenic Diet Foods To Avoid: 108 Foods That’ll Slow Your Fat Loss

There are 108 ketogenic diet foods to avoid that will slow down (or shut down) your body’s fat burning capability. Remember that carbs must be kept very low to remain in ketosis. Most people need to stay within 20-30 grams of net carbs per day, and protein shouldn’t make up more than 20-25% of total calories. Too many carb or protein-centric foods can very quickly bring you out of ketosis and slow down your body’s fat burning capabilities. This is why the foods below should be avoided on a ketogenic diet. Not to worry, though. We’ve made it easy for you with this cheat sheet covering the biggest keto foods to avoid and why. We chunked it down by macronutrient: Want a quick and easy meal plan that doesn’t include any of these keto-unfriendly foods? We’ve created one for you. Click here to get the FREE downloadable meal plan now. Carbs to Avoid on a Ketogenic Diet Grains All grains—and foods made from grains (yup, even whole grains)—should be avoided. Grains contain too many carbs and will interfere with ketosis, slowing weight loss. That includes*: Beans and Legumes Beans provide nutrition for those on a regular diet, but they’re not fit for the ketogenic diet due to their high starch (carb) content. Avoid legumes including*: Fruit is healthy, right? Sure, but that doesn’t mean they’re keto-compliant. Fruit is high in sugar and carbs, so is usually a no-go on the keto diet. That includes tropical fruits, fruit juices, dried fruits, and fruit smoothies (for the most part). If you do have fruit, choose lower-sugar options like blueberries, blackberries, and raspberries, and eat them sparingly. Starchy Vegetables Avoid any vegetables that grow beneath the ground and focus on more on the leafy greens. The high starch content of some vegetables (like tho Continue reading >>

Can You Eat Healthy, Complex Carbs While In Ketosis?

Can You Eat Healthy, Complex Carbs While In Ketosis?

Can You Eat Healthy, Complex Carbs While in Ketosis? One of the biggest rules on the ketogenic diet is keeping carb intake very low, which is necessary for ketosis . However, you might be wondering whether you can eat healthy, complex carbohydrates while in ketosis. Can they fit at all into a ketogenic diet, or should they always be eliminated completely? Whether you, a friend, or family member have pondered this question, this article will help clear things up by talking about the difference between carbohydrate types and whether or not healthy carbs can be a part of keto. Lets start by taking a look at the different types of carbohydrates. Theyre generally divided into three categories: simple carbs, starches, and fiber. Simple carbs are fast-acting, meaning theyre absorbed into the bloodstream almost immediately. They are commonly known as bad carbs. Simple carbs come from: Added sugars like cane sugars (white and brown), honey, agave nectar, maple syrup, powdered sugar, high fructose corn syrup, etc. Naturally occurring simple sugars found in fruits and milk. Starches are known as complex carbs and come from whole foods like rice, corn, potatoes, peas, beans, oats, breads, and pastas. Starchy carbs that are grains can be either whole grain or refined, meaning the bran and germ of the grain has been removed along with most of the nutrition and fiber. In normal nutrition terms, these complex carbs are often referred to as good carbs because they provide more nutritional value than simple carbs. However, in the context of a ketogenic diet, even complex carbs are a problem because they can kick us out of ketosis. Well get into that in a minute, but lets first look at the last type of carbohydrate. Fiber is a carbohydrate found in plant foods like vegetables, fruits, nu Continue reading >>

How Many Carbs Per Day On A Low-carb Ketogenic Diet?

How Many Carbs Per Day On A Low-carb Ketogenic Diet?

Although my initial plan was to include this post in All You Need to Know About Carbs on Low-Carb Ketogenic Diet, I decided it deserves to be discussed separately. How Many Carbs per Day to Stay in Ketosis? As described in my post How Does the Ketogenic Diet Work? Weight Loss and 3 Main Effects of Ketosis, weight loss on a ketogenic diet is achieved by limiting the daily intake of net carbs and getting your body in a metabolic state known as ketosis. While in ketosis, your body effectively uses fat for fuel. In general, the daily intake of net carbs required to enter ketosis could vary from 20 to 100 grams per day (and very rarely over 100 grams per day). Most people, who have experienced ketosis, claim to have reached that state at about 20-50 grams of net carbs per day. I'd suggest you start at 20-30 grams and see how you can adjust it for your needs. There are two ways to find your ideal net carbs intake: Low to high method Start from a low level of net carbs to ensure you quickly enter ketosis (~ 20 grams of net carbs per day). When you detect ketosis after about 2-3 days, start adding net carbs (about 5 grams each week) until you detect a very low-level or no ketones (using Ketostix or blood ketone meter). This is usually the most reliable and quickest way to discover your net carbs limit. It could be a bit hard the first couple of days, as you have to give up almost all carbs from one day to another but it will be worth it. This method is highly recommended. High to low method Assuming you're not in ketosis, start from a relatively high level of net carbs (~ 50 grams) and keep reducing (about 5 grams each week) until you detect presence of ketones. This is a less difficult approach but not recommended, as you may spend a long time out of ketosis before you find yo Continue reading >>
