What Does Ketosis Smell Like

What Is Acetone?

What Is Acetone?

You can find it in paint thinners, nail polish, and the manufacturing of plastics. But it’s also found naturally (and safely) in the human body, especially in those following a ketogenic diet. What we’re talking about here is acetone, a ketone body produced in the ketosis process, which has many benefits in the body. But what is acetone, exactly? What role does it play in ketosis? Those are questions we’ll be diving into below so you can better understand how this molecule fits into your ketogenic diet and why it’s important. What is Acetone? Acetone is a type of ketone. When someone is eating a high-fat and low-carb diet (namely, the ketogenic diet) or goes through prolonged fasting and there isn’t enough glucose in the body for fuel, the liver starts breaking down fatty acids for energy for the body and the brain. This is the process known as ketosis, the primary function and goal of the ketogenic diet. When ketosis happens, water-soluble molecules called ketone bodies, or just simply “ketones,” are released. These three ketones are: Acetoacetate Beta-hydroxybutyrate Acetone Acetoacetate is created first, followed by beta-hydroxybutyrate and acetone. Acetone is created spontaneously from the breakdown of acetoacetate and is the simplest and most volatile ketone. It diffuses into the lungs and exits the body from exhaled breath. Acetone Benefits on the Ketogenic Diet One way that those on a keto diet ensure they maintain their ketosis, and receive the benefits of ketosis, is by measuring the amount of acetone on the breath. Typically, the higher amount of acetone present, the further they are into ketosis. Weight Loss Benefits There are many reasons someone might choose to follow a keto diet and put their body in ketosis. Benefits of being in ketosis incl Continue reading >>

The Causes And Solutions For Bad Breath (ketosis Breath)

The Causes And Solutions For Bad Breath (ketosis Breath)

If you’re on a low-carb diet, not all the outcomes are good. One of the side effects you could notice is bad breath. It’s commonly nicknamed ketosis breath, whether it happens when following the ketosis diet, but it can happen with all low carb/high protein diets. In fact, bad breath is becoming an epidemic. This is because so many people now are following these low carb diets. So, you’re definitely not alone. In fact, scientists say that 40% of people on these types of diets report bad breath as one of the worst side effects. I’ve been in your position before with my low carb diets. Your best friend likely has, too. We just get so embarrassed about our bad breath that we tend not to mention it. We just hope that we can mask it with some breath mints. But what is the real cause of bad breath on the ketosis diet? Just why do low carb diets make us stink? And is there anything that we can do to stop the problem? I can share some very positive news. You can stop ketosis breath becoming an issue. You don’t need to become part of the growing epidemic. I’m going to share everything that you can do to stop ketosis breath becoming a problem. So, Why Do We Get Bad Breath? Let’s start with how low carb diets work. When we stop feeding ourselves as many carbs, our bodies have to get the energy in other ways. They do this through the burning of fat, which means the release of ketones in the body. It’s a chemical process since the body can’t create the carbohydrates that it would need to help It’s this process that is causing the bad breath. The great news is that you’re sticking to your diet and you will see a smaller waistline. It will be successful, and you will be able to lose weight. Of course, the downside is that you have to deal with the breath. The mos Continue reading >>

Ketone Smell

Ketone Smell

Home The last few 100s I've finished, my wife has informed me I have a keytone smell that permeates throughout my body as well as my breath. She has also noticed this to a lesser degree when I've been building mileage. Could this be the result of fat metabolism? It usually subsides after 24-36 hours. Anyone else experience this or are their spouses keeping quiet? I've never really had this problem until the last fews years. Harry Strohm I am not an expert but it is my understanding that a keytone smell would be associated with protien conversion not fat converson. Paul Comet Are you on a diet? Sounds like ketosis. When I fasted on water and vitamin pills for 8 days, I had that smell big-time. I recall reading that the smell comes from muscle tissue being destroyed. But I'm no expert on physiology. Scott Weber When Al Howie brought up diabetes and ketones, here's what he was referring to: When too little insulin is present, your body cannot use glucose for energy. It is then forced to break down fat for energy. Your body produces ketones (acids) and releases them into the blood and urine. When people with Type I diabetes do not take enough insulin, especially in times of stress or illness, ketones are produced. Large amounts of ketones can lead to diabetic ketoacidosis, a medical emergency. Karl King Ketosis is a result of profoundly low carbohydrate availability and is normally associated with prolonged starvation. The take home message is: eat something, preferably some carbos. I try to run with an intake of 30 to 50 calories per mile and have never experienced a ketone aroma when I run, though I've noted it in others after a long run. Dr Martin W. Fryer, (PhD School of Physiology & Pharmacology University of New South Wales) Without trying to be too technical I think Continue reading >>

How Do You Know You Are In Ketosis?

How Do You Know You Are In Ketosis?

I've not noticed any of these alleged ketosis symptoms and I've gone weeks without consuming carbs. This includes extended periods of fasting. I think I notice a few changes in mood during periods when I'm in extensive ketosis, but nothing that would suffice to serve as an indicator. I think it needs to be recognised that ketosis is not a binary in/out affair and also that just eating a high fat diet doesn't necessarily mean you'll be in deep ketosis. This table is fantastic. It shows that the levels of ketones in the blood vary as follows: 0.1 for a normal diet, up to 0.3 on a 12-24 hour fast, up to 1 during late pregnancy, 0.7-1 in a 5-10 day old baby, up to 2 post-exercise, 2-3 on a 48-72 hour fast, up to 3 on a high fat diet, 4-6 in late pregnancy after 48hours fasting and up to 25 in an untreated diabetic. I think this shows that eating high fat is not the be all and end all, and exercise and fasting are major factors and also that ketosis is not a radically unusual state, but rather something that neonates and pregnant women routinely enter (without bizarre symptoms). Notably the liver can hold up to 100-120g of carbohydrate, so you may not quickly enter ketosis after ceasing to eat carbs, your stored glycogen (and any excess protein) will see to your body's needs for some time. If, as is common among paleos, you're eating quite a lot of meat, then you'll be generating a lot of glucose endogenously- more than enough to limit ketosis (which seriously begins once you exceed more than 25% of calories from protein). Also I do wonder how low carb "very low carb, (no fruits)" is, since you can be extremely high carb without eating any fruit. If you really want to be sure you're in ketosis, then do some intense exercise and eat not too much protein and lots of coconut (w Continue reading >>

Ketosis Symptoms

Ketosis Symptoms

Ketosis symptoms are a result of the way the body gets rid of the excess ketone bodies which build up in the blood stream when a person eats a low carb, ketogenic diet. In short, the body has three ways of dealing with excess ketone bodies: First, the muscles liver and brain can burn them for energy in the cells. Second, the body can breathe ketones out through the lungs. And third, the body can flush ketones out through the kidneys and urine. Legionella Testing Lab - High Quality Lab Results CDC ELITE & NYSDOH ELAP Certified - Fast Results North America Lab Locations legionellatesting.com The ketosis symptoms associated with the benign dietary ketosis caused by eating a low carb, ketogenic diet are not dangerous. They may differ for each individual, with the most common symptoms being: Ketosis breath, which has a fruity odor, and the person in deep ketosis may feel a sort of slight burning in the nose and a slight smell of ammonia. Dry mouth, which is alleviated by drinking more regular tap or bottled water. (Reverse osmosis water will make this worse.) In the first week of beginning a ketogenic diet, most people experience frequent urination followed by fatigue, as insulin levels come down, and the kidneys release extraneous water stores. Minerals such as sodium, magnesium and potassium are also lost with excreted urine, and it is the mineral loss that causes the fatigue. This can be offset by eating more salt, drinking more fluids, and increasing the intake of magnesium and potassium containing foods. (Dairy foods and avocados are high in potassium, and you can drink broth for more sodium.) A slight headache at first which goes away in a few days. This is usually a sign of not getting enough salt. Ketone bodies become detectable in the urine. Ketone bodies are molecu Continue reading >>

What Is Ketosis?

What Is Ketosis?

What is ketosis? Being in ketosis is truly a magical thing. Ketosis happens when your body starts producing ketone bodies instead of utilizing carbohydrates as energy. Both can be used as energy sources, but I find that converting to a fat-burner over a carbohydrate-burner to be most favorable. Signs of being in ketosis There are a few signs that could suggest you’re in ketosis: a metallic taste in mouth strong smelling urine random bursts of happiness (it’s weird, but it’s true!) decreased appetite How to get into ketosis The best way to get into ketosis is to immediately drop all major carb sources in your diet and focus on high-quality fats. Some find that going extremely low carb for a couple days will jumpstart ketone production and ultimately reaching a state of ketosis. Initially when you first remove a majority of carbohydrates from your diet, most people experience signs of lethargy and flu-like symptoms. This is what people consider the “low carb flu.” The low carb flu could last anywhere from a couple days to a couple weeks. It’s important to stay extremely hydrated on a ketogenic diet, so much make sure you’re getting enough water and electrolytes. If you’re one of the lucky ones, you won’t experience any low carb flu symptoms at all. Carbohydrate tolerance varies from person to person to maintain a ketogenic state. Some report that they can eat up to 80 grams and still be in ketosis. A safe spot for most people seems to be between 20-30 grams. Benefits of being in ketosis You will find it hard to believe that an array of benefits can be obtained from following a ketogenic diet, but the proof is in the research! Some of these include: Effortless weight loss Awesome blood sugar regulation Reduced blood pressure Reduced inflammation Appetite Continue reading >>

The 4 Ketosis Symptoms You Should Be Looking For

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 >>

Ketogenic Diet & Body Odor

Ketogenic Diet & Body Odor

Pills, powders, shakes -- Americans are willing to do whatever it takes to lose weight, even risk unpleasant odors emitting from their bodies. High-fat, low-carb diets such as the Atkins diet, also referred to as ketogenic diets, induce ketosis, which causes you to lose your appetite. But ketosis has a number of unpleasant side effects, including body odor and bad breath. Consult your doctor before starting a ketogenic diet. Video of the Day About the Ketogenic Diet The ketogenic diet was first introduced in the 1920s by Dr. Russell Wilder as a method of controlling epileptic seizures, according to Dr. Liu Lin Thio, assistant professor of neurology at Washington University School of Medicine. Starvation had been used as a way of treating seizures since ancient times, says Thio, and a high-fat, low-carb diet mimicked starvation. The diet, however, is not meant to be followed for a long period of time and is deficient in a number of essential nutrients including B vitamins, vitamins C and D, magnesium, calcium and iron. Modified ketogenic diets, such as the Atkins diet, are less restrictive but produce similar results. The Chemistry Behind the Diet Normally, your brain uses glucose as a source of energy. Glucose comes from the breakdown of carbohydrates found in foods such as bread, fruit and milk. But during times of starvation, your body uses your stored fat for energy instead. The fat is broken down in the liver and made into ketones, then transported to the brain to be used as energy. The goal of the ketogenic diet is to get you into ketosis, which is characterized by high levels of ketones in your blood. For weight loss, ketosis prevents you from feeling the hunger pangs associated with most low-calorie diets, says Dr. John McDougall. Chemically, ketones are a type o Continue reading >>

5 Strategies To Overcome Keto Breath

5 Strategies To Overcome Keto Breath

5 Strategies to Overcome Keto Breath The ketogenic diet has absolutely exploded in popularity over the last few years and for good reason. The benefits of a low-carb, high-fat, moderate-protein diet are astounding and include improvements in inflammation, metabolism, brain function, and the list goes on. Because I often recommend this type of eating style, I have become well aware of some of the challenges that people face when making the switch and one of the biggest complaints I get is keto breath. Shortly after beginning a ketogenic or low-carb diet many people report a persistent breath odor or bad taste in the mouth. This is very common and fortunately it can be negated when you follow the right steps. This article goes over 5 strategies to overcome keto breath naturally. Causes of Keto-Breath A ketogenic diet has many great health benefits, including reducing inflammation and improving fat burning and brain function. While ketones have an incredible therapeutic impact in our body, they also cause a fruity breath. However, many times the cause of the bad breath is not the ketones…but excess protein or possibly poor oral hygiene or digestive distress. When it comes down to it, there are only two primary causes of bad breath that are directly related to a ketogenic eating style and they are: Ketones on the breath and over-consumption of protein. Breathing off Ketones: When we start burning fat as a primary fuel source over carbohydrates our bodies produce different byproducts as a result. The main byproduct of burning fat are the ketone compounds and, although these are what we want for energy, one type of ketone in particular (acetone) is released in the breath and may have a fruity odor in higher amounts (1). There are 2 ways to see if this is from ketones. The f Continue reading >>

10 Signs And Symptoms That You're In Ketosis

10 Signs And Symptoms That You're In Ketosis

The ketogenic diet is a popular, effective way to lose weight and improve health. When followed correctly, this low-carb, high-fat diet will raise blood ketone levels. These provide a new fuel source for your cells, and cause most of the unique health benefits of this diet (1, 2, 3). On a ketogenic diet, your body undergoes many biological adaptions, including a reduction in insulin and increased fat breakdown. When this happens, your liver starts producing large amounts of ketones to supply energy for your brain. However, it can often be hard to know whether you're "in ketosis" or not. Here are 10 common signs and symptoms of ketosis, both positive and negative. People often report bad breath once they reach full ketosis. It's actually a common side effect. Many people on ketogenic diets and similar diets, such as the Atkins diet, report that their breath takes on a fruity smell. This is caused by elevated ketone levels. The specific culprit is acetone, a ketone that exits the body in your urine and breath (4). While this breath may be less than ideal for your social life, it can be a positive sign for your diet. Many ketogenic dieters brush their teeth several times per day, or use sugar-free gum to solve the issue. If you're using gum or other alternatives like sugar-free drinks, check the label for carbs. These may raise your blood sugar levels and reduce ketone levels. The bad breath usually goes away after some time on the diet. It is not a permanent thing. The ketone acetone is partly expelled via your breath, which can cause bad or fruity-smelling breath on a ketogenic diet. Ketogenic diets, along with normal low-carb diets, are highly effective for losing weight (5, 6). As dozens of weight loss studies have shown, you will likely experience both short- and long Continue reading >>

Low-carb Diets Can Cause Bad Breath

Low-carb Diets Can Cause Bad Breath

Low-carb diets may be good for your waistline, but you might not be able to say the same for your breath. Low-carb lifestyle junkies are more likely to suffer from a seldom discussed side effect of such diets -- halitosis, aka bad breath. And since more than 25 million people say they have tried the Atkins diet (not to mention other low-carb eating plans), according to the National Marketing Institute, bad breath may be an epidemic! Bad breath in the low/no-carb sect is often caused by certain chemicals that are released in the breath as the body burns fat. They are called ketones, and entering into a fat-burning state of ketosis is the hallmark of the Atkins diet. So the good news is that if your breath stinks, you're probably doing a good job of sticking to that low-carb diet. "Carbohydrates aren't readily available, so you start to use other fats and proteins as your source of energy, and as a result you are going to get a breath problem," explains Kenneth Burrell, DDS, the senior director of the council on scientific affairs of the American Dental Association. Pass the Bread? This is not an oral hygiene problem, Burrell says, so "all the brushing, flossing, and scraping of the tongue that you can do is not possibly enough to overcome this." The bottom line is that you must "reconsider the diet and modify it so this doesn't happen," he says. Sure, "there may be some ways to mask it by using mouthwashes, but you can't overcome the fundamental problem other than by changing the diet -- or at least introducing some carbohydrates." "It's a difficult problem to solve because if one uses any sucking candy or lozenge, one has to be careful that it has no sugar in it" as sugar is a big no-no on many low-carb eating plans, says S. Lawrence Simon, DDS, a New York City periodon Continue reading >>

How To Detect Ketosis

How To Detect Ketosis

How can you tell if your low-carbing efforts have been effective enough to induce ketosis? Learn how to check your ketones! The state of ketosis The state of ketosis means that the body has switched from depending on carbohydrates for energy to burning fats for fuel. This means not only dietary fats (olive oil, guacamole, deep-fried pig ears), but also all the jiggly bits around your waist — clearly a desirable state for anyone looking to shed extra weight. When the body metabolizes fat, it generates molecules called ketones (also known as ketone bodies). As you restrict carbohydrate intake and amp up the dietary fat, more fat is metabolized and a greater quantity of ketones are created. Most of the cells in your body — including those in your brain — are able to use ketones for energy, although many people experience a few days’ adjustment period, often called the low carb flu. One of the varieties of ketones generated — acetone — cannot be used by the body and is excreted as waste, mostly in the urine and the breath. Conveniently, this makes it very simple to measure whether or not you are in ketosis. Upon entering ketosis, some people report a distinct change in the smell of their breath as a result of the extra released acetone. It could be “fruity” — it’s been likened to overripe apples — or even “metallic.” If you notice this happening during your first few days of changing your diet, it could be a good sign you’re in ketosis. The unusual smell isn’t anything dangerous, but it could be annoying. Drinking plenty of water should help, or get yourself some sugar-free gum. Most people report “keto-breath” diminishing after the first few weeks. Detecting ketones in urine The more accurate way — and the one we recommend — to check f Continue reading >>

Ketoacidosis

Ketoacidosis

Ketoacidosis is a metabolic state associated with high concentrations of ketone bodies, formed by the breakdown of fatty acids and the deamination of amino acids. The two common ketones produced in humans are acetoacetic acid and β-hydroxybutyrate. Ketoacidosis is a pathological metabolic state marked by extreme and uncontrolled ketosis. In ketoacidosis, the body fails to adequately regulate ketone production causing such a severe accumulation of keto acids that the pH of the blood is substantially decreased. In extreme cases ketoacidosis can be fatal.[1] Ketoacidosis is most common in untreated type 1 diabetes mellitus, when the liver breaks down fat and proteins in response to a perceived need for respiratory substrate. Prolonged alcoholism may lead to alcoholic ketoacidosis. Ketoacidosis can be smelled on a person's breath. This is due to acetone, a direct by-product of the spontaneous decomposition of acetoacetic acid. It is often described as smelling like fruit or nail polish remover.[2] Ketosis may also give off an odor, but the odor is usually more subtle due to lower concentrations of acetone. Treatment consists most simply of correcting blood sugar and insulin levels, which will halt ketone production. If the severity of the case warrants more aggressive measures, intravenous sodium bicarbonate infusion can be given to raise blood pH back to an acceptable range. However, serious caution must be exercised with IV sodium bicarbonate to avoid the risk of equally life-threatening hypernatremia. Cause[edit] Three common causes of ketoacidosis are alcohol, starvation, and diabetes, resulting in alcoholic ketoacidosis, starvation ketoacidosis, and diabetic ketoacidosis respectively.[3] In diabetic ketoacidosis, a high concentration of ketone bodies is usually accomp Continue reading >>

Why Does Your Breath Stink On Low-carb Diets?

Why Does Your Breath Stink On Low-carb Diets?

Why It Happens Carbohydrates normally comprise your body's main source of energy, because carbohydrates break down quickly and easily into glucose and pass into cells, supplying them with the energy they need. When you follow a low-carbohydrate diet, your body doesn't ingest enough carbohydrate to fuel all your cells. So your body begins to break down stored fat as an energy source. During this process, your body creates incompletely burned byproducts called ketones. Ketones pass from your body in urine -- that's why people on low-carb diets often test their urine -- and, less pleasantly, through exhalation. Ketones produce an acetone-like smell, which causes the distinctive breath of ketosis. Carb Limits Not all people on a low-carb diet produce ketones. While everyone enters ketosis at their own pace, most people don't until their carbohydrate intake falls below 50 grams of carbohydrate per day, Dr. Peter Attia explains on his website, The Eating Academy. In many cases, you won't enter ketosis unless you take in 20 grams of carbohydrates or less each day, MayoClinic.com states. Some diets that call themselves low-carbohydrate diets deliberately keep the amount of carbohydrates you ingest well above this level, specifically to keep you from going into ketosis. Steps to Take Keto breath means that your diet is working; you're breaking down fat and using it for energy. But that doesn't mean you -- or your closest friends -- have to like it. You can take steps to reduce the smell. Drinking plenty of water washes the ketones out in your urine, leaving fewer to expel via your lungs. Gums, mints and other breath fresheners can help temporarily, but watch out -- many contain carbohydrates. Look for brands that use artificial sugars or you might unwittingly put yourself out of Continue reading >>

Ammonia Smell During Exercise On Ketogenic Diet – Q&a

Ammonia Smell During Exercise On Ketogenic Diet – Q&a

Question: My question relates to the pungent smell of ammonia in my sweat during a hard work out, seems to start about 45 minutes in and gets stronger from then. This started very soon after the diet. I have recently started a high protein slow carb diet,am drinking between 3 and 4 litres of water a day (currently 180lbs with 21% body fat)have plenty of energy and feel alert and well. From your work I gather this could be the result of ketosis and burning protein and fat for energy? Two questions please: 1. Is this OK? 2. Is there anyway to eliminate the smell? Answer: This is a fairly common report on very low-carbohydrate/ketogenic diet (defined, once again, as any diet containing less than 100 grams of carbohydrate per day), a report of a fairly strong ammonia smell in the sweat during exercise. As I discuss in detail in my first book The Ketogenic Diet this ammonia is produced due to the ultimate breakdown of ATP to ADP to AMP and ammonia. This appears to occur more readily when muscle glycogen is depleted (as occurs with the combination of of a very low-carbohydrate intake along with training) and may be part of the increased protein requirements that have been known to occur with endurance training (this is discussed in detail in The Protein Book). I would mention that it appears that this ‘protein breakdown’ is not actually coming from the breakdown of skeletal muscle itself; rather it’s from the breakdown of BCAA (branched-chain amino acids) within the free amino acid pool. So is this ok? So long as dietary protein intake is sufficient, I don’t see this as being any real problem. The effect is slight in terms of the absolute amount of protein being broken down (in terms of grams) and so long as protein intake is sufficient, there shouldn’t be any detri Continue reading >>
