What Is Ketosis?
"Ketosis" is a word you'll probably see when you're looking for information on diabetes or weight loss. Is it a good thing or a bad thing? That depends. Ketosis is a normal metabolic process, something your body does to keep working. When it doesn't have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones. If you're healthy and eating a balanced diet, your body controls how much fat it burns, and you don't normally make or use ketones. But when you cut way back on your calories or carbs, your body will switch to ketosis for energy. It can also happen after exercising for a long time and during pregnancy. For people with uncontrolled diabetes, ketosis is a sign of not using enough insulin. Ketosis can become dangerous when ketones build up. High levels lead to dehydration and change the chemical balance of your blood. Ketosis is a popular weight loss strategy. Low-carb eating plans include the first part of the Atkins diet and the Paleo diet, which stress proteins for fueling your body. In addition to helping you burn fat, ketosis can make you feel less hungry. It also helps you maintain muscle. For healthy people who don't have diabetes and aren't pregnant, ketosis usually kicks in after 3 or 4 days of eating less than 50 grams of carbohydrates per day. That's about 3 slices of bread, a cup of low-fat fruit yogurt, or two small bananas. You can start ketosis by fasting, too. Doctors may put children who have epilepsy on a ketogenic diet, a special high-fat, very low-carb and protein plan, because it might help prevent seizures. Adults with epilepsy sometimes eat modified Atkins diets. Some research suggests that ketogenic diets might help lower your risk of heart disease. Other studies show sp Continue reading >>
What Does It Mean When My Blood Gets Acidic?
For real, not the alternative babble? That can be because of: Too little bicarbonate due to too much metabolic acid rests one can’t excrete due to renal failure (including severe dehydration). Ketosis due to the burning of fat in extremely low intake of carbs, this we also see it diabetic ketoacidosis where due to too little insulin in type I diabetes they can’t burn their glucose, become ketotic, blood glucose rise, the urinate a lot and get seriously dehydrated, hypotensive, so a potentially fatal condition. Too much CO2 (with water it becomes a weak acid H2CO3) in your blood due to lung problems so not being able to exhale it e.g. in COPD or other forms of respirator insufficiency. Continue reading >>
What Does It Mean That I Burn Fat Over Carbs?
Your body is always burning a combination of carbs (as glucose, stored in glycogen stores in the body) and fat. At rest, you're mostly burning glucose, with a small percentage of fat. Fat is converted to acetyl sugars through the beta oxidation process and then enters the Krebs cycle like a normal sugar, though it requires oxygen (thus, aerobic metabolism). When you start exercising, you initially burn ATP and ATP-PC for 30 seconds or so, then the glycogen stores take over the load (anaerobic metabolism). As the glycogen stores are used, the aerobic metabolism sources (fats) slowly ramp up. After the glycogen stores are depleted (it's never fully unused, it just ramps down), the aerobic metabolism mostly takes over. When you "hit the wall" while doing exercise it's possibly due to the fact that aerobic metabolism requires oxygen to complete the kreb's cycle. When they mean when they say: "burning fat over carbs" it means that you're utilizing your aerobic metabolism store more than your anaerobic metabolism store. Additionally, when your glycogen stores are low, your body can convert fat to glucose in a process called Gluconeogenesis. If that's what they're referring to, they're misunderstanding the process that a low-carb diet is utilizing to burn fat. In that case your body is still burning glucose, it just turns the fat into glucose in a multi-step process in order to keep your blood sugar stable. It's not as simple a process as simply eating carbs, but it's possible to sustain your body on it simply by eating protein and fats (and a very low percentage of carbohydrates). Gluconeogenesis in combination with aerobic metabolism is the basis of the Ketogenic diet and the initiation phase of the Atkins diet.

The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating
The only hard and fast rule of health is that health is personal and what works well for one person may not work for someone else. Aside from that rule, there are “frameworks” that seem to benefit large groups of people. One more level down from that are alternative strategies that benefit smaller groups. Ketosis is likely one of those alternative strategies that works well for certain, smaller groups of people. So, right off the bat I want you to understand that Ketosis might not be for everyone. I’m going to lay out the case for potential benefits of Ketosis. If it sounds interesting and beneficial to you, then consider trying it. (see our free cheat sheet to help you). What is Ketosis Ketosis occurs when liver glycogen gets depleted and the body burns fatty acids for fuel. The primary driver of this state is a very low carbohydrate intake. Often, it also requires a low protein, higher fat intake. You can also achieve a state of ketosis by not eating altogether. The creation of ketones is a byproduct of this metabolic state. Ketones are a source of fuel, just as glucose is a source of fuel. Ketones tend to have some added benefits, though. What role does Ketosis play in human health? Ketosis allows our bodies to function in the absence of carbohydrates, both physically and mentally. Instead of burning carbohydrates, or converting protein to glucose, the body burns ketones. This is pretty much a survival mechanism. It allows your body to function in a state of caloric deprivation. This is why ketosis often gets bad press (as it’s linked to “starvation”). Being a survival mechanism doesn’t make it invalid as a strategy, though. There can still be potential benefits to be had. Let’s cover a few of them… Ketosis and Accelerated Fat Loss Being in ketosis Continue reading >>
What Is Ketosis?
Most people have heard they should eat a low-carb diet for weight loss and/or better health, but the word “ketosis” might have some tilting their heads in confusion wondering what’s so special about this funny term. Don’t worry; we’ve got all the details you need to understand the process of ketosis in the body — and more importantly, how you can implement it in your own life! Before you can fully understand ketosis, let’s cover some simple facts about the body and energy. The primary source of energy in the body — which normally fuels every function of the body, from brain cognition to athletic performance — is glucose. You typically get glucose from your diet by eating carbohydrates like: sugar bread grains Beans and legumes fruit starchy vegetables These carbs either turn immediately into glucose in the body or are stored as glycogen in the body to be used as glucose later. However, sometimes the body will have a low supply of glucose, also known as blood sugar. This could be because a person is eating a low-carb diet. When there is no longer enough glucose for the body to use, it turns to an alternative source of energy: your fat stores. It takes the fat stores and the liver breaks them down to make glucose. And when this happens, elements known as ketones are formed as a byproduct of the process. There are three main types of ketone bodies that form in your body during when this happens: Acetate Acetoacetate Beta-hydroxybutryate (BHB) Once ketones are formed, your body can use them as alternative fuel. KETOSIS FOR WEIGHT LOSS Probably the most widely talked about use for ketosis right now is utilizing it for weight loss. In fact, the ketogenic diet is built around creating ketosis in the body. There are several benefits you can experience when you Continue reading >>
Ketosis, Ketones, And How It All Works
Ketosis is a process that the body does on an everyday basis, regardless of the number of carbs you eat. Your body adapts to what is put in it, processing different types of nutrients into the fuels that it needs. Proteins, fats, and carbs can all be processed for use. Eating a low carb, high fat diet just ramps up this process, which is a normal and safe chemical reaction. When you eat carbohydrate based foods or excess amounts of protein, your body will break this down into sugar – known as glucose. Why? Glucose is needed in the creation of ATP (an energy molecule), which is a fuel that is needed for the daily activities and maintenance inside our bodies. If you’ve ever used our keto calculator to determine your caloric needs, you will see that your body uses up quite a lot of calories. It’s true, our bodies use up much of the nutrients we intake just to maintain itself on a daily basis. If you eat enough food, there will likely be an excess of glucose that your body doesn’t need. There are two main things that happen to excess glucose if your body doesn’t need it: Glycogenesis. Excess glucose will be converted to glycogen and stored in your liver and muscles. Estimates show that only about half of your daily energy can be stored as glycogen. Lipogenesis. If there’s already enough glycogen in your muscles and liver, any extra glucose will be converted into fats and stored. So, what happens to you once your body has no more glucose or glycogen? Ketosis happens. When your body has no access to food, like when you are sleeping or when you are on a ketogenic diet, the body will burn fat and create molecules called ketones. We can thank our body’s ability to switch metabolic pathways for that. These ketones are created when the body breaks down fats, creating Continue reading >>
Lose Weight By Achieving Optimal Ketosis
Do you want to lose weight? Here’s number 16 of my 18 best tips. All of the published tips can be found on the How to Lose Weight page. Before we get started, here’s a short recap of the tips so far: The first and most crucial piece of advice was to choose a low-carb diet. The next were eating when hungry, eating real food, eating only when hungry, measuring progress wisely, being persistent, avoiding fruit, beer and artificial sweeteners, review your medications, stressing less and sleeping more, eating less dairy and nut products, stocking up on vitamins and minerals, using intermittent fasting and finally, exercising smart. This is number sixteen: 16. Get into optimal ketosis Warning: Not recommended for type 1 diabetics, see below. We’ve now arrived at tip number 16. If you’re still having trouble losing weight, despite following the 15 pieces of advice listed above, it might be a good idea to bring out the heavy artillery: optimal ketosis. Many people stalling at weight plateaus while on a low carb diet have found optimal ketosis helpful. It’s what can melt the fat off once again. So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume less calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect. Video course Do you know exactly how to eat a low-carb and high fat diet (LCHF)? This is required for ketosis. If not the easiest way is watching this high quality 11-minute video course on how to eat LCHF, and the most important things to think a Continue reading >>
Not to be confused with Ketoacidosis. Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Ketosis is a result of metabolizing fat to provide energy. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose. It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body. Ketone bodies are formed by ketogenesis when liver glycogen stores are depleted (or from metabolising medium-chain triglycerides). The main ketone bodies used for energy are acetoacetate and β-hydroxybutyrate, and the levels of ketone bodies are regulated mainly by insulin and glucagon. Most cells in the body can use both glucose and ketone bodies for fuel, and during ketosis, free fatty acids and glucose synthesis (gluconeogenesis) fuel the remainder. Longer-term ketosis may result from fasting or staying on a low-carbohydrate diet (ketogenic diet), and deliberately induced ketosis serves as a medical intervention for various conditions, such as intractable epilepsy, and the various types of diabetes. In glycolysis, higher levels of insulin promote storage of body fat and block release of fat from adipose tissues, while in ketosis, fat reserves are readily released and consumed. For this reason, ketosis is sometimes referred to as the body's "fat burning" mode. Ketosis and ketoacidosis are similar, but ketoacidosis is an acute life-threatening state requiring prompt medical intervention while ketosis can be physiological. However, there are situations (such as treatment-resistant Continue reading >>
Tweet Ketosis is a state the body may find itself in either as a result of raised blood glucose levels or as a part of low carb dieting. Low levels of ketosis is perfectly normal. However, high levels of ketosis in the short term can be serious and the long term effects of regular moderate ketosis are only partially known at the moment. What is ketosis? Ketosis is a state the body goes into if it needs to break down body fat for energy. The state is marked by raised levels of ketones in the blood which can be used by the body as fuel. Ketones which are not used for fuel are excreted out of the body via the kidneys and the urine. Is ketosis the same as ketoacidosis? There is often confusion as to the difference between ketosis and ketoacidosis. Ketosis is the state whereby the body is producing ketones. In ketosis, the level of ketones in the blood can be anything between normal to very high. Diabetic ketoacidosis, also known as DKA, only describes the state in which the level of ketones is either high or very high. In ketoacidosis, the amount of ketones in the blood is sufficient to turn the blood acidic, which is a dangerous medical state. When does ketosis occur? Ketosis will take place when the body needs energy and there is not sufficient glucose available for the body. This can typically happen when the body is lacking insulin and blood glucose levels become high. Other causes can be the result of being on a low carb diet. A low level of carbohydrate will lead to low levels of insulin, and therefore the body will produce ketones which do not rely on insulin to get into and fuel the body’s cells. A further cause of ketosis, less relevant to people with diabetes, is a result of excessive alcohol consumption. Is ketosis dangerous? The NHS describes ketosis as a pote Continue reading >>
What Is Maturity? How Can The Maturity Of A Person Be Defined?
Maturity is never a destination that you reach someday upon growing up. It's more like certain amount of common sense or general knowledge as well as sufficient control upon your emotions that you gather into action in times of need. Lets visit a few examples to drive the point home. It not immature to cry. Crying merely helps us vent out our emotions. Crying and doing nothing about what was lost is a sign of cowardice. The act of recognizing what needs to be done at that point of time is brilliance and determination. But the act of realizing that something needs to be done and staying out will yield no outcomes is maturity. It is not the merely the ability to make big decisions at a prestigious position, but also the conscious choice to understand the small pieces that fit in to make the greater things. When at a bus stand, or any public place and someone throws a plastic wrapper towards a dustbin, but the wrapper falls on the ground. You get conscious that everyone’s watching and so its normal to feel hesitant to do the cleanup. But if you just pick up the wrapper and put it back in the dustbin without thinking of others, that’s maturity. When a friend or a stranger picks up an argument with you, and you know fundamentally that you are right, but still give up the argument because it seems to you that the point is not worth wasting your time and energy, that’s maturity. When a friend fails to keep his word and you choose not to be mad at him/her. Instead you decide not to rely on him/her further but still be friends, that’s maturity. When you have a lot of work piled up and you have just the weekend to finish it off, but your friends are calling you for a road trip after a long time. You are uncertain what to do. You had waited for a long time to get together Continue reading >>
Why Are Answers On Quora Collapsed?
I’m asked to answer this. There are already a boatload of answers, so I doubt I’m adding much to the discussion. But I’ll chime in with my 1½ cents (I’m underbidding the competition here, so take this for what it’s worth). Quora’s official answer (Quora's answer to Why are answers on Quora collapsed?) is the top answer to the question, but to be fair, it isn’t actually helpful—at least, point 3 thereof isn’t; it contains what I view as a significant misrepresentation to the effect that “editing” will save an answer. In fact, only very rarely will editing undo a collapsed answer. Duplicate answers (more than one answer on the same question page) are collapsed automagically, whether or not they say the same thing. The (only) way you can end up with duplicate answers is through merging of questions. Quora policy on merging is that “if all answers are equally applicable to both questions, they should be merged.” Or put another, simpler, way, if the two questions mean the same thing they should be merged. Now it turns out that whether two questions will actually mean the same thing might be in the eye of the answerer, and bad or even random merges are common on Quora. I’ve occasionally answered what were two questions when I started and come back to find the question merged and I then have one answer (apparently the answer that had more “views” at the time of the merge) visible and one collapsed. Here’s Quora’s official announcement about how merging works. Introducing Question Merging by Laura Scharff on The Quora Blog I don’t have a big problem with the “one-answer-per-question” rule, and when I find out that someone has merged two questions I answered, I will sometimes edit the visible answer so that it contains the contents of b Continue reading >>
Ketosis: What Is Ketosis?
Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates. Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly. Problems associated with extreme levels of ketosis are more likely to develop in patients with type 1 diabetes compared with type 2 diabetes patients. Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose. Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid. As ketone levels rise, the acidity of the blood also increases, leading to ketoacidosis, a serious condition that can prove fatal. People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to avoid or treat diabetic coma. Some people follow a ketogenic (low-carb) diet to try to lose weight by forcing the body to burn fat stores. What is ketosis? In normal circumstances, the body's cells use glucose as their primary form of energy. Glucose is typically derived from dietary carbohydrates, including: sugar - such as fruits and milk or yogurt starchy foods - such as bread and pasta The body breaks these down into simple sugars. Glucose can either be used to fuel the body or be stored in the liver and muscles as glycogen. If there is not enough glucose available to meet energy demands, th Continue reading >>
7 Signs You Might Be In Ketosis When Doing The Ketogenic Diet
One of the main goals of starting the ketogenic diet is to get your body into a metabolic state known as ketosis. Note: If you don’t know what the ketogenic is all about then check out the Ketogenic Diet: Beginner’s Guide to Keto and Weight Loss. This is when your body starts to produce a lot of ketones to supply energy for your body. Why is this good? Because it means your body has converted from a sugar-burner to a fat-burner. If your body is burning fat for energy then something amazing starts to happen. The fat on your body starts to disappear. But how do you know when you’re in ketosis? Besides using test strips or an instrument there are some signs that your body will give. 7 Signs You Might Be in Ketosis These don’t 100% guarantee that your body is in ketosis but if it is in ketosis then these signs will appear. 1. Weight Loss One of the obvious signs of ketosis is weight loss but this can also be pretty deceptive because many people don’t experience the kind of weight loss that they expect. This can happen for a variety of reasons but when you get close to entering ketosis or do enter ketosis you’ll find that you lose a healthy amount of weight quickly. For example, when you switch to low carbs you usually experience significant weight loss in the first week. In fact, my wife lost 12 lbs in the first 28 days of Keto and I lost 13. This isn’t your body burning fat but finally being able to release the water that was being held by the fat cells. If your fat cells don’t release this water then they can’t flow through the bloodstream to be used as fuel so losing water weight is a good thing. After the initial rapid drop in water weight, you should continue to lose body fat consistently if you are able to stick with the low-carb aspects of the diet Continue reading >>
What Is Ketosis Diet And What Does It Contain?
A keto diet is well known for being a low carb diet, where the body produces ketones in the liver to be used as energy. It’s referred to as many different names – ketogenic diet, low carb diet, low carb high fat (LCHF), etc. When you eat something high in carbs, your body will produce glucose and insulin. Glucose is the easiest molecule for your body to convert and use as energy, so it will be chosen over any other energy source. Insulin is produced to process the glucose in your bloodsteam, by taking it around the body. Since the glucose is being used as a primary energy, your fats are not needed, and are therefore stored. Typically on a normal, higher carbohydrate diet, the body will use glucose as the main form of energy. By lowering the intake of carbs, the body is induced into a state known as ketosis. Ketosis is a natural process the body initiates to help us survive when food intake is low. During this state, we produce ketones, which are produced from the breakdown of fats in the liver. The end goal of a properly maintained keto diet is to force your body into this metabolic state. We don’t do this through starvation of calories, but through starvation of carbohydrates. Our bodies are extremely adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the main energy source. Cholesterol. A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. Weight Loss. As your body is burning fat as the main source of energy, you will essentially be using your fat stores as an energy source while in a fasting state. Blood Sugar. Many studies show the decrease of LDL cholesterol over time and have shown to eliminate ailments such as type 2 di Continue reading >>
What Is Ketosis? Hint: It Can Help You Burn Fat & Suppress Your Appetite
We’ve longed been told that calorie restriction, increasing exercise and reducing dietary fat intake are the keys to weight loss. But, if you’ve ever attempted to control your weight by subsisting on fewer calories — especially from mostly bland “diet foods”— you’re already probably aware that this typically produces minimal results and is extremely hard to stick with long-term or consistently. Considering the high rates of obesity now facing most developed nations — along with an increased risk for health conditions like diabetes or heart problems as a result — researchers have been anxiously working on how to suppress appetite and achieve weight loss in a healthy, sustainable manner. The keto diet has emerged over the past several decades as one potential answer to this large-scale weight loss problem. (1) While there are some differences in opinion, depending on who you ask, regarding the best approach to very low-carb dieting, studies consistently show that the ketogenic diet (also called the keto diet) produces not only substantial weight loss for a high percentage of people who adhere to it, but also other important health benefits such as reductions in seizures, markers of diabetes and more. The keto diet revolves around eating foods that are high in natural fats, consuming only moderate protein and severely restricting the number of carbs eaten each day. Even if you don’t have much weight to lose, entering into a state of ketosis can be helpful for other reasons — such as for improved energy levels, mental capabilities and mood stabilization. What Is Ketosis? Ketosis is the result of following the ketogenic diet, which is why it’s also sometimes called “the ketosis diet.” Ketosis takes place when glucose from carbohydrate foods (like Continue reading >>
