Keto-adaptation (on A Zero Carb Diet)
For a comprehensive page on keto-adaptation and performance by the experts visit this page, or just read The Art and Science of Low Carbohydrate Living which covers this subject in depth and many others: According to Owsley “The Bear” Stanley This is not a dedicated nor complete article, this page is an extract from Owsley’s correspondence with others. See this page for more info. Keto-adaptation on zero carbs should be complete in 3-4 weeks. Ketosis is the situation in which ketones are voided in the urine. It takes place within a few hours of blood glucose stabilising and no glucose entering from the diet. At this point many of the body-structures, such as the brain and deep dense tissues like cartilage and tendon will still require glucose and will not take up the ketone by-products of fat metabolism. So the excess ketones are voided and the necessary glucose is obtained from glycerol and liver glycogen. If carbs continue in small amount, this condition will persist. If however carbs do not reappear in the diet, then the body begins to adapt to using the ketones as food hence the term keto-adaptation. During the period of adaptation, energy levels are subjectively low. As the body begins to run most of the glucose-dependent tissues on ketones, energy increases several fold and some additional benefits are realised, such as a lack of ‘hunger pangs’, increased endurance time, increased strength, a feeling of well-being, and rapid bodyfat loss. Keto-adaptation takes time, from a very minimum of about 2 weeks in a very remarkable person, to from three to six weeks in most people. This is a very hard but very important first hurdle to overcome in getting comfortable in the all-meat dietary path. A person in permanent ketosis will feel tired, lacking in energy mo Continue reading >>
Of The Keto Diet?
There are many awesome benefits that come with adopting a low-carb ketogenic diet, such as weight loss, decreased cravings and even possibly reduce disease risks. With that being said, it’s also good to talk about possible ketosis side-effects when ingesting these specific ketone supplements, so you know fully what to expect when you get started on this mission. If you’ve already heard about some of the side-effects that come with this special diet and are starting to freak out, don’t panic. We’re going to break down everything you need to know when it comes to what your body will experience when using these supplements for the first time. It’s important to remember, not everyone experiences side-effects when starting a ketogenic diet and thankfully, the symptoms are all very temporary and it can pass very quickly. It varies with the individual, but just to make sure all your bases are covered, we’re going to break down each possible side effect that you could possibly experience. 1. Flu Symptoms Within the first 2-4 days of beginning this diet, a common side-effect is known as the “ketosis flu” or “induction flu” because it mimics the symptoms of the actual flu. This means you might experience: Headaches Lethargy Lack of motivation Brain fog or confusion Irritability Although these symptoms typically go away completely within a few days, they are also completely avoidable if you stay very hydrated and increase your salt intake and like always, be sure you're eating enough fat. 2. Dizzyness & Drowsiness As you start dumping water, you'll lose minerals such as salt, potassium and magnesium. Having lower levels of these minerals will make you tired, lightheaded or dizzy. You may also experience muscle cramps, headaches and skin itchiness. Fatigue Continue reading >>
The 4 Ketosis Symptoms You Should Be Looking For
Ketosis is the condition in which your body begins burning fat instead of carbs for its energy source. The benefits of ketosis range widely, but some of the best include: fat loss increased endurance less cravings shredded physique neurological optimization But how do you know when you’re in ketosis? Are there symptoms that you’re in ketosis? Is there a way to “feel” like you’re in ketosis? Obviously the best way to see if you’re in ketosis is to test you breath, blood, or urine. However, we’ve constructed the following list to help you detect the signs that you’ve transitioned into ketosis and turned your body into a fat burning machine! If you’ve been on the Ketogenic Diet for at least a week, run through this list of ketosis symptoms, and see if they fit what you’re experiencing! 1. Ketosis Breath A popular report from many low-carb and keto dieters is that their breath is less than desirable. The smell has been compared to fingernail polish remover, which is believed to come from the presence of acetone. Acetone is, of course, a ketone body, and is also found in many brands of nail-polish remover. 2. Keto Flu After a life full of ingesting large portions of carbs for energy, dropping carbs and moving into ketosis can often result in ketosis symptoms known collectively as the “keto flu.” It’s not unheard to feel light-headed, fatigued, or anemic when your body runs out of carb stores and begins turning to fat for its fuel source. You might feel irritable, or short-tempered; this is your body’s natural reaction to having sugar removed. Much like an addict in rehab, when you cut out mass amounts of processed sugars, you turn into a bit of a monster. Ketosis symptoms also include nausea, or stomach aches. These can be caused by your stomach r Continue reading >>
Is There A Dark Side Of Ketosis?
I can’t remember what appetizer she pointed to, but the woman sitting to the left of me said this so casually, and several folks at the table knew exactly what she meant, confirming what I’d long suspected: Ketogenic diets have officially gone mainstream – or recognizable at a party mainstream at least – in 2017. Let’s back up and demystify ketosis, which simply means you’re utilizing ketone bodies – more commonly called ketones – rather than glucose as your body’s primary fuel. Just like your car uses gasoline, your body needs fuel. That usually means glucose. But let’s say you’re on a very-low carbohydrate, higher-fat diet. Your body doesn’t get a lot of glucose, which primarily comes from carbohydrate and to a lesser degree protein. That means your liver’s backup glucose (glycogen) also becomes in short supply. Unlike your car, your body doesn’t just shut down. Thankfully, you have an alternative fuel source called ketones. Ketones are organic compounds your liver always makes. You’re cranking out ketones right now as you read this. During starvation or (more likely) when you restrict carbohydrate and increase fat intake, your body uses ketones as its primary fuel. In other words, when your body doesn’t receive or can’t make enough glucose, it shifts to this alternative fuel. Almost every organ can utilize ketones except for your red blood cells (which don’t have ketone-metabolizing mitochondria) and liver. Your liver, in fact, does the heavy lifting. This hardworking organ metabolizes fat into three ketone bodies: acetoacetate (ACA), beta-hydroxybutyrate (BHB), and acetone.(1) BHB is the first substrate that kicks ketosis into action. Among its benefits, BHB reduces chronic inflammation and restores healthy inflammation levels. In Continue reading >>
How A Ketogenic Diet Can Help Manage Cortisol Levels
Fatigued individuals often experience erratic cortisol levels. Fortunately, there are things that we can do to better manage our stress response and related hormones. Lifestyle changes such as exercise and stress management therapy can have a powerful effect on our brain’s stress response. Diet is another example of the things that we can control, and one diet has demonstrated great potential for regulating hormones. It is known as the ketogenic diet, and its impact on cortisol levels can be dramatic. The Ketogenic Diet Examined To better understand how a ketogenic lifestyle can impact your cortisol levels – and by extension, your adrenal fatigue – it is helpful to first understand how ketosis works and how your body reacts to this state. Once that is understood, then the benefits of a ketogenic diet will become clear. Ketosis Defined Ketosis is a metabolic state in which the body burns ketones produced by the liver instead of glucose so that it can avoid using protein from the muscles as fuel. This body state occurs when you deprive the body of carbohydrates and force your glycogen levels down from their normal highs. This low-carbohydrate lifestyle is an outlier in the Western world, where most citizens and their governments have long adhered to and promoted the idea that the majority of a person’s diet should be comprised of carbohydrates. It must be observed, however, that ketosis is not just something that can be induced through diet. It can also be a natural state. However, for the purpose of controlling cortisol levels, the goal of achieving ketosis is an intention act that relies on dietary changes for its success. How the Body Adapts to Ketogenic Diets There has been quite a bit of debate over the safety of ketosis over the long term. While high levels Continue reading >>
Ketosis – What Is That All About?
What’s it all about? Is it good for you? Is it bad for you? What’s it like? How do I ‘do’ ketosis? How do I know I’m in ketosis? The questions everyone who’s Banting wants the answers to. Ketosis, in chef speak, is quite simply a state your body enters once it has been deprived of glucose. Your body switches to burning fat for energy (stored fat or fat that you have eaten) instead of glucose. A side-effect of that process is the release of ketone bodies into the blood stream. When you’re starved of glucose, your body has no choice but to burn fat for fuel, so it needs little explanation as to why ketosis works at melting fat like a blow heater on an ice sculpture. Ketosis comes with some added extras, namely a commonly noted sense of euphoria or lucidity and increased energy levels. A downside includes toothbrush-proof halitosis, which stems from the secretion of ammonia through the lungs as a side effect of burning all that fat. Some people on low-carb diets have reported kidney stones, gallstones and a number of other ailments. Scientific research on both sides of this debate is being done all the time, but in our experience from talking to the members of our community and tracking their data, it is generally a case of what was done before they started Banting and not Banting itself. But, this post isn’t here to debate that, it serves as a ‘how to’ and not as a ‘you should’. Eat more buttery or creamy sauce on your steak and eat less steak. Your body can convert protein into glucose so too much meat will hinder your progress. What doIdo? Theoretically it is very easy. Avoid anything with high carbs in it. If you’re not sure what those might be, consult the Real Meal Revolution ‘Red List’. Even dipping your toe into the red list will ruin Continue reading >>
Source Ketosis is the name for a state achieved on a low-carbohydrate diet. According to WebMD, when you are in ketosis, it means your body is burning fat for energy. When that happens, your body releases ketones into your bloodstream, and you are in ketosis. This state may cause a host of temporary symptoms. Understanding the Symptoms Many dieters develop symptoms that let them know ketones are present. For many people beginning a low-carb diet, ketosis kicks in after a few days of strict adherence to the diet. In fact, many low-carbohydrate plans, such as Atkins and paleo, have an initial phase in which dieters take in extremely low amounts of carbohydrates (usually less than 25 grams per day) to kick start ketosis. You can test for ketones in the urine using ketosis strips, or rely on symptoms to tell you ketosis has been achieved. Early Stages Symptoms of ketosis vary, depending how long you've been in the state. In the early stages, the symptoms may be a bit unpleasant. However, as your body adapts to ketones in the bloodstream, symptoms may decrease. Early symptoms usually last for several days or up to a week in some people. This period of symptoms is sometimes called the keto flu. It may continue until your body is used to burning fat instead of glucose. Afterwards, the levels of ketones should lessen, but that doesn't mean you aren't losing weight. It means your body has found a balance and is no longer producing excess ketones. According to Diet Doctor, early stage symptoms include: Flu-like symptoms, such as fatigue and headache Nausea Brain fog Constipation Leg cramps Feeling unusually thirsty Irritability Heart palpitations Dry mouth Ketosis breath, which smells fruity and unpleasant Decreased energy and weakness Dizziness Sleep problems Cold hands and feet Continue reading >>
When Not To Be On A Ketogenic Diet
When Not To Be on a Ketogenic Diet A ketogenic diet is a very low carbohydrate, moderate protein and high fat based nutrition plan. A ketogenic diet trains the individual’s metabolism to run off of fatty acids or ketone bodies. This is called fat adapted or keto adapted, when the body has adapted to run off of fatty acids/ketones at rest. This nutrition plan has been shown to improve insulin sensitivity and reduce inflammation. It also improves cellular healing and mitochondrial biogenesis which supports stronger and healthier cells. All of this leads to reduced risk of chronic disease as well as improved muscle development and fat metabolism (1, 2). Where Ketosis Can Be Extremely Beneficial There are certain cases, where I typically recommend a ketogenic diet as the research appears to support that ketosis significantly improves the functionality of these individuals. Overweight or Obese Neurodegenerative Conditions such as dementia, Alzheimer’s and Parkinson’s Most Cancers but especially those of the brain, nervous system and blood (leukemia) Chronic Pain Seizure Disorders Non-Elite athletes or individuals looking for higher mental & physical performance The final one is the area that I and many others who have pursued a state of ketosis fall into. At this point in my life, I have no chronic diseases, I feel great 99% of the time, but I am always looking to improve my productivity and performance. I have found being in mild-ketosis to be one of the best ways to improve my energy, mental acuity, creativity, physical strength and overall life performance. There is no one diet that works perfectly for everyone. Ketosis has the potential to benefit everyone, but under unique circumstances it would not be warranted. Here are a list of special cases where long-term st Continue reading >>
Why Do I Have No Energy On Paleo?
One of the biggest reasons why people try Paleo in the first place is to get more energy. They read the testimonials from people who went from constantly-exhausted couch potatoes to vibrant, joyful CrossFit athletes, and they want that transformation for themselves. It’s perfectly understandable to expect that a healthier diet will give you more energy – which is why it’s such a betrayal when sometimes, it doesn’t. If Paleo means spending all day in a haze of exhaustion and brain fog, something’s gotta give. So what could cause this sudden dip in energy when eating healthier foods is supposed to make you feel better? First off, start with the obvious. If you’ve just quit caffeine, if you’re not getting enough sleep regularly, or if you’ve just made another drastic life change, your diet should not be the first place to look for answers. But assuming that nothing else is responsible, it’s reasonable to start troubleshooting your food to make sure you’re not accidentally shooting yourself in the foot with your efforts to eat better. Fatigue Culprit #1: Transition For the first 3 weeks or so of your new Paleo lifestyle, the most likely culprit is simply the transition period. Changes, especially big changes like your entire diet, are exhausting. That’s one of the reasons why habit has such a strong power over us: it takes less energy just to do whatever we’re used to doing. Until you get into a routine, you have to use willpower, and that’s draining, both mentally and physically. Your brain is working a lot harder than it usually has to, so it’s no surprise that you’re tired. On top of that, Paleo tends to be lower in carbs, with most of your calories coming from fat. If you’re switching from a high-carb diet, there’s usually a week or two Continue reading >>
7 Ways To Fight Fatigue On A Low-carb Diet
You have just started a low-carb diet. It’s going ok. Except that you are exhausted all the time. Tiredness is a common low-carb diet side effect, especially in the beginning. Moving from carbs to fat as your main fuel source is a major change for your body. Your metabolism needs time to adjust. Until it does, you might feel tired, and experience low-carb flu symptoms. The duration of this period varies for each individual – it can last from several days to a couple of weeks. Here are some tips on how to speed up this transition and feel better throughout. 1. Eat enough fat Once you cut your carbs, dietary fat becomes your main source of energy. Make sure you are getting enough. On any low-carb high-fat (LCHF) diet, most of your calories should come from fat – about 60%-80%. Check the fat intake guidelines of your chosen diet plan. This is not easy for beginners. Our perception of fat has been destroyed by years of negative propaganda in the media. You need to make an effort to include extra fat to your diet. Otherwise you could fall behind. Not enough fat means less fuel for your body, and less energy. Here’s how to crank up the amount of fat in your diet: Eat fatty meats (for example, sirloin or rib-eye steak, pork belly, lamb neck, bacon, sausages), poultry with skin, fatty fish like salmon and mackerel. Jazz up your cooked vegetables and salads with plenty of butter and high-quality vegetable oils (coconut oil, avocado oil, flax oil, cold-pressed olive oil) Use full-fat cream (or maybe even butter!) in your tea and coffee Choose snacks with some fat in them, for example, cheese, macadamia nuts, brazil nuts, avocados Use high-fat sauces (e.g Bearnaise) and condiments (e.g. mayonnaise) – preferably home-made More tips on how to eat more fat 2. Eat regularly Continue reading >>
Does A Low-carb Diet Make You Tired?
A low-carb diet, whether it's Atkins, ketogenic or a Paleo plan, promises weight loss and vitality. Not everyone thrives on such a diet, however. Carbohydrates are the body's primary source of fuel -- too few can mean your energy levels plummet. In addition to possible side effects such as constipation, headaches and weakness, you may also experience tiredness and fatigue. Video of the Day What Counts as Low-Carb? The publication "Dietary Guidelines for Americans, 2010" recommends you get between 45 percent and 65 percent of daily calories from carbohydrates, including those found in breads, pasta, vegetables and fruit. Although many diet plans reduce your intake of carbohydrates, a true low-carb diet limits your intake of carbs to fewer than 150 grams per day, according to a 2007 paper published in the "American Journal of Clinical Nutrition." Ketogenic diets, which are ultra-low-carb plans that may be followed during certain phases in bodybuilding or to treat specific medical conditions, may restrict you to just 30 to 40 grams per day. Cut out most grains, breads, pizza, fruit and sugar to reduce your carb intake to low levels. Your body uses carbohydrates as an immediate source of fuel. Carbohydrates raise your blood sugar and, in turn, stimulate certain brain chemicals that blunt your appetite and make you feel good. Many athletes, especially endurance athletes, need carbohydrates to perform at their best. When you limit carbohydrates, your body may feel weak and lack energy. You'll switch from burning carbohydrates for fuel to burning fat, a process called ketosis, which requires extra energy from your body. The resulting ketones can cause side effects, such as nausea, lightheadedness and tiredness. Athletes who stick to low-carb plans may feel exhausted by their w Continue reading >>
Symptoms Of Ketosis:
If you are considering the ketogenic diet or have already started down this carb-free road, you may wonder what you can expect. Here’s the thing. Ketosis looks different for everyone, but I will share many of the most common symptoms with you today. If something other than what’s listed here is happening to you, just do a quick Google search for that symptom and keto. You should be able to find what you’re looking for! The Early Signs: The early signs of ketosis vary from person to person. The biggest impact on how quickly you notice the symptoms of ketosis will have a lot to do with how you ate before you started the diet. If your diet was very high carb, you might get hit pretty quickly and furiously with what we like to call the “Keto Flu.” This can last anywhere from 3 days to a week or more. Once your body has adapted to burning ketones for energy instead of glucose, you’ll be golden so don’t give up! Here’s what you can expect within the first 2-3 days of starting the Ketogenic Diet: Fatigue & Weakness (lack of concentration) Headaches Metallic taste or sweet taste in your mouth (I experienced this, and it tasted like blood in my mouth) Lightheaded / Dizzy upon standing Heightened Thirst Hunger / Sweet or Carb Cravings Dry Mouth possibly paired with “Keto Breath.” Stomach Discomfort / Mild Nausea / Cramping Trouble Sleeping or Staying Asleep (early waking) Water weight loss (perhaps an excessive loss of weight within the first two weeks) Frequent Urination Allergies or cold like symptoms may flair up For the ladies: Period issues: You may experience a longer, shorter, earlier, later period because of Keto. Seriously it causes all of that. Each woman is different, and I have experienced every one of those issues with my period since starting ket Continue reading >>
How Long Does It Take To Feel Increased Energy And Mental Clarity After Starting The Ketogenic Diet?
I’m currently on the Keto Diet, so I’m speaking from my personal experience. For me it took about 2 weeks but I was kinda doing it wrong at first. I was still eating too many carbs and then I wasn’t eating enough fat. I have to tell you that it is an awesome diet! Brain fog is real! Be warned though, you need to eat enough calories or you’ll lose muscle mass as well. Also, as meat is expensive, this diet will be expensive too. Calculate your Basal Metabolic Rate and aim for at least that many calories. You can use BMR calculators such as this one. The length of time will likely vary depending on your age, height, gender, and weight, (or caloric requirements) as well as how often you workout and what your body fat percentage is currently like. I’d guess between 2–3 weeks. This is not the kind of energy you were expecting…? Personally, I wouldn’t exactly characterize it as increased energy, just consistent energy. Before I went keto, I would have spurts of energy and constantly grow tired shortly after eating. I had to take excessive amounts of caffeine to stay awake. This never happens anymore. It’s not a cure-all. Sometimes I don’t get enough to eat or I don’t get enough sleep so I still can get tired but it’s nothing compared to before. Nevertheless, a cup of coffee is usually plenty enough to help me during these times. I’ve been on the Keto diet for almost 3 months. I lost over 25 lbs and went down from about 28% to 17%< body fat and I don't feel sick or tired all the time, infact I feel great! Some people adjust the macros (i.e. 65% fat 30% protein 5% carbs or 60% fat 30% protein 10% carbs) and they do just fine. Find what works for you, any reduced carbs will be helpful to your long term health but it may or may not get you all the way to Continue reading >>
Keto Flu Symptoms, Low Carb Headache And Fatigue In Ketosis
I would have it as a guess that more than half of the people I have seen on the Ketogenic Diet have experienced to some degree what is known as Keto Flu or Low Carb Flu. Mostly a feeling of fatigue, slight headaches or nausea overcomes them. The symptoms of Keto Flu / Low Carb Flu usually occurs in the first two weeks of a person beginning a ketogenic diet and entering into ketosis. They can come and go if you’re not getting the right nutrition. Share the Infographic above on your site! The other half follow what is recommended and replenish themselves with essential minerals and electrolytes that are being depleted. These electrolytes are flushed from their bodies as they rid themselves of the water retention and sodium their old high carb diets made them hang on to. What are the symptoms of Keto Flu or Low Carb Flu? The symptoms of Keto Flu as you begin to restrict your carbs and enter into a state of ketosis varies from individual to individual. They differ in duration and severity, dependant on what high fat, low carb foods you include in your ketogenic diet and their mineral content. The Most Common Keto Flu Symptoms Experienced are: What is known as a Low Carb Headache, Diarrhea Fatigue Weakness Nausea Dizziness Low Blood Pressure Brain Fog What Causes Keto Flu / Low Carb Flu, Fatigue, Headache and other Symptoms of Ketosis? Firstly I’d like to bring this away from the technicalities of minerals and nutrients for a second and get people thinking laterally about what they are embarking upon. Essentially when going into a Ketogenic Diet, Ketosis or most Low Carb Diets, we are breaking an addiction. Most western populations are drawn to carbohydrates, or put even more simply sugar! Sugar gives us an instant rush and satisfaction as it flows through our bodies, co Continue reading >>
First Week: Top 3 Keto Conundrums
The low carb lifestyle is known to sculpt some serious fat off your body. Many followers of the keto diet experience rapid weight loss, low hunger levels, and good energy levels. Since you cut out most of the high sugar foods, controlling your calories becomes a breeze. Sounds like an easy plan to success, right? Those who joined the ketogenic army can attest that the early weight loss comes with a toll. The first week of low carb living can be daunting, both mentally and physically. As your brain and body are adapting to a life without glucose, you may become outright miserable. Don’t go shoving cake down your neck just yet – the misery passes. To have an idea what you’ll go through, check out these common side effects that most go through when switching to a keto diet. Usually they only last for the first few days to a week, but preparing yourself for what might come will always help. Mental and Physical Fogginess The first major sign – coming 2 or 3 days into your ketogenic transition – will be the fogginess. You’re brain likes to take it easy and it if had a choice, would run on only glucose. As your body is switching from glucose to ketones as its main source of energy, your body will continue to burn the last stores of glycogen. This results in a foggy haze that might make it hard to concentrate. You might find yourself staring into space or feeling lethargic, but have no fear – it will pass. Headaches might pound at your door, nausea can pit in your stomach, muscle cramps can ruin your day and irritability can spark arguments, but knowing this can help you plan. Switch your diet in the middle of the week, so you will have the weekend to fully rest and recover from your transition. What we suggest is to go super low carb for the first week, which mea Continue reading >>
