The Top 10 Ketosis Mistakes And How To Prevent Them
What mistakes are you making when it comes to your health? I know I’ve been making plenty. That’s why I’m tracking my data in this recent ketosis experiment that I’m doing. What about you? Most people think that the ketogenic diet is just “low-carb” which leads them to make many mistakes that prevent them from not reaping all of the benefits of ketosis that they could. What benefits? How about an improved immune system, increased longevity, lower inflammation, effortless weight loss, decreased hunger, reduced risk for disease and more. Read on to know the top 10 ways that people make mistakes with ketosis and how you can prevent them. 1: Not tracking protein intake By far the biggest problem with a ketogenic diet is not tracking how much protein you are eating. The far majority of people are simply eating too much lean protein, which ends up kicking them out of ketosis. Protein can turn into carbs by a metabolic process called gluconeogenesis, meaning “making new carbs.” This then spikes insulin, and reduces ketone levels. Even though you are eating super low carb, this could make your body switch back and forth between energy systems, which will lead to high levels of fatigue or “low carb flu.” The easiest way to avoid this mistake is by tracking your ketone levels to see how you respond to different amounts and different types of meat. Everyone is different, so the only way you can tell is by tracking. I “listened to my body” before and it didn’t work. I wasn’t in ketosis when I thought I was. I also thought ketosis kind of sucked. It didn’t, I was just wrong. The only way you know is by tracking. If you consume more fat with protein, it will slow this effect. So think fattier cuts of meat, and less muscle meat. But wait, are you going to Continue reading >>
Is It Possible To "screw Up" Your Metabolism?
Our brains, in relation to weight, are responding, adapting and planning "machines." Just for a single example, the brain of an anorexic has learned that it is STARVING - that food is very, very, very scarce and that it needs to absolutely maximize any "energy" (food) that it gets. Given that our brains/bodies are not separate, and "metabolism" is a whole-body process/event, this has profound implications.Just because in time the body/brain begins to be fed does not mean that it will just "snap to" and interpret this as the new "normal." It has learned, sometimes over many years that food is extremely scarce and when the next food/energy is coming is unpredictable and can take a loooooong, looooong time from last ingestion and even then will be in a scarcity amount. Thus, it responds accordingly. Even yo-yo dieting brings about huge changes. And that makes sense as well. Our brain is our "regulator." It learns with yo-yoing another version of the above. Who knows when the next time of scarcity with come... The implications are very real for those who have been substantially overweight, eating disordered, have a history of yo-yoing 10 lbs up and down, sometimes many, many times in their lives. One of my favorite pieces on this is Ned Koch's blog piece on compensatory adaptation...which doesn't just apply to eating...but to all behaviors and delves into the less than conscious mechanisms that are at work in response to even subtle signals in this adaptation process. What it boils down to for me, in "person-speak" is that we are constantly signaling and communicating with our bodies/brains and our bodies/brains in turn are continuously responding and adapting...for better or worse. We may not think or know we are "communicating," but we are. For me, Dr. Sharma is high, hig 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 >>
How Does The Ketogenic Diet Affect Your Metabolism?
Dr. Eric Westman explains the impact that low carbohydrate diets have on the human metabolism. This video is part of a debate featuring Dr. Eric Westman, co-author of “The New Atkins For A New You.” Dr. Westman practices and teaches at Duke and is not an employee of Atkins. He is, however, one of the leaders of ketogenic diets and the metabolic theory of cancer movement. This video discusses how the ketogenic diet can be used to treat and maybe someday even prevent some forms of cancer (Youtube). Advertisements Continue reading >>
What Everybody Ought To Know About Ketosis
Recently I wanted to explore the world of Ketosis. I thought I knew a little bit about ketosis, but after doing some research I soon realised how wrong I was. 3 months later, after reading numerous books, listening to countless podcasts and experimenting with various diets I know have a sound understanding of ketosis. This resource is built as a reference guide for those looking to explore the fascinating world of ketosis. It is a resource that I wish I had 3 months ago. As you will soon see, a lot of the content below is not mine, instead I have linked to referenced to experts who have a greater understanding of this topic than I ever will. I hope this helps and if there is something that I have missed please leave a comment below so that I can update this. Also, as this is a rather long document, I have split it into various sections. You can click the headline below to be sent straight to the section that interests you. For those that are really time poor I have created a useful ketosis cheat sheet guide. This guide covers all the essential information you should know about ketosis. It can be downloaded HERE.

The Ketogenic Diet's Effect On Cortisol Metabolism
(Related post: Red Light, Green Light: responses to cortisol levels in keto vs. longevity research) One of the myths surrounding ketogenic diets comes from misunderstanding the role of cortisol — the "stress hormone". In a previous post, we addressed one of the arguments behind this myth: the idea that to activate gluconeogenesis (to make glucose out of protein), extra cortisol must be recruited. That is just factually incorrect, as we showed in the post. The other argument, which we address here, is more complex. Like the previous cortisol myth, it involves a faulty chain of reasoning. Here are the steps: Ketogenic diets may raise certain measures of cortisol. Chronically elevated cortisol is correlated with metabolic sydrome, and therefore higher cortisol measures may indicate the onset of metabolic syndrome. Therefore, ketogenic diets could cause metabolic syndrome. Metabolic syndrome is a terrible and prevalent problem today. It is that cluster of symptoms most strongly identified with diabetes — excess abdominal fat, high blood sugar, and a particular cholesterol profile — but also correlated with other life-threatening conditions such as heart disease and cancer. In this post, we're going to explain some of the specifics of cortisol metabolism. We'll show how this argument is vague, and how clarifying it leads to the opposite conclusion. The confusion may all stem from misunderstanding one important fact: different measures of cortisol are not equivalent. First, though, there is an important reason why the argument doesn't make sense. We already know that a ketogenic diet effectively treats metabolic syndrome. As we will describe below, it turns out that certain cortisol patterns are strongly linked to metabolic syndrome, and might even be a cause of metabol Continue reading >>

Metabolic Damage And Keto Adaptation – Why And How.
I have been getting questions about how to keto adapt, and how long does keto adaption take etc. and does keeping calories up while keto dieting, does this reduce metabolic damage or adaptation even if your carbs are very low? So what this question is kind of centering on is the concept about metabolic damage and adaptation. My take is that your body becomes very efficient at burning calories when you drive your calories lower and lower and do more and more steady state cardio. I’m not talking about 1 or 2 – 45 min cardio sessions a week, I’m talking more about one or two hours of cardio per day. So this is a high amount of cardio and very low calories. Essentially what you’re doing is you’re just kind of metabolically shocking your system and your body responds by becoming a lot more efficient. Now these mechanisms of efficiency are starting to get studied in the scientific world but that’s basically kind of what we are talking about. Right now there isn’t much evidence, but they do believe something is there. The basis of these adaptations is definitely present. So how this does relate specifically to a ketogenic diet, and you know because your carbs are really low, can you still keep your calories high so you don’t get these metabolic adaptations. And the answer is yes. So what about ketosis? Let’s Get Scientific for a Moment This is a really important key to remember, ketosis is not weight loss, instead ketosis is actually a metabolic state when fat is being burned as your primary fuel source and then ketones are being produced. Ketones are by products of fat metabolism. Fat is getting oxidized at a very high rate, which results in ketone production and then you can measure ketones in either your urine (not recommended as I discuss here in my TOP K Continue reading >>
What is ketosis? Ketosis is the physiological state where the concentration of ketone bodies in the blood is higher than normal. This is generally agreed to be at beta-hydroxybutyrate (BHB) concentrations greater than 0.5 mM. How to achieve ketosis? Ketosis occurs either as a result of increased fat oxidation, whilst fasting or following a strict ketosis diet plan (ENDOGENOUS ketosis), or after consuming a ketone supplement (EXOGENOUS ketosis). When in a state of ketosis the body can use ketones to provide a fuel for cellular respiration instead of its usual substrates: carbohydrate, fat or protein. Why does ketosis exist? Normally, the body breaks down carbohydrates, fat, and (sometimes) proteins to provide energy. When carbohydrate is consumed in the diet, some is used immediately to maintain blood glucose levels, and the rest is stored. The hormone that signals to cells to store carbohydrate is insulin. The liver stores carbohydrate as glycogen, this is broken down and released between meals to keep blood glucose levels constant. Muscles also store glycogen, when broken down this provides fuel for exercise. Most cells in the body can switch readily between using carbohydrates and fat as fuel. Fuel used depends on substrate availability, on the energy demands of the cell and other neural and hormonal signals. The brain is different as it is dependent on carbohydrates as a fuel source. This is because fats cannot easily cross the blood-brain barrier. The inability to make use of energy within fat poses a problem during periods where there is limited carbohydrate in the diet. If blood glucose levels fall to low, brain function declines. Relatively little energy is stored as carbohydrate (2,000 kCal) compared to fat (150,000 kCal). The body's store of carbohydrates runs Continue reading >>
Ketogenic Diet: Lose Weight With Ketosis
If you’ve faced a health or weight loss plateau, you might have heard about the ketogenic diet. But what is ketosis? Going into ketosis, or a state of fat burning, isn’t complicated, but it takes motivation. It’s a way to burn stubborn fat and lose weight. Today we’ll explore questions like what is the ketogenic diet, what is ketosis and how does it work, what are keto foods, and the benefits and dangers involved in following a ketogenic diet plan. As a bonus: I’ll provide a 1 week ketogenic diet plan plus a complimentary workout plan. Together, they will help you burn stubborn fat. We try so hard to lose a few kilos or pounds, but most of the time we don’t manage to. Luckily, there is an easy way to turn the body into a fat burning machine: the ketogenic diet. Why the ketogenic diet? It’s commonly believed that consuming fewer calories will lead to weight loss. It looks something like this: Calories stored (or lost) = Calories consumed – Calories burned Following this equation, if we eat less, we’ll create a calorie deficit and in turn, use our stored fat . Assumably, we’ll lose weight. It seems easy to do. But, things go wrong. First, as many know from experience, eating less is torturous. Second, we often don’t lose weight with calorie restriction diets. Worse than that, we sometimes lose the weight and gain it back–and do damage to our metabolism in the process. Losing weight and gaining it back means a slower metabolism. This is because body fat storage is not just a matter of calories in and calories out. It is the result of millions of years of evolution. To understand what happens, we need to review some basic biochemistry. We know that an adult has: A glycogen (carbohydrate) reserve that lasts about 1 to 2 days of survival, maximum. Fat Continue reading >>
Your Brain On Ketones
The modern prescription of high carbohydrate, low fat diets and eating snacks between meals has coincided with an increase in obesity, diabetes, and and increase in the incidence of many mental health disorders, including depression, anxiety, and eating disorders. In addition, many of these disorders are striking the population at younger ages. While most people would agree that diet has a lot to do with the development of obesity and diabetes, many would disagree that what we eat has much to do with our mental health and outlook. I believe that what we eat has a lot to do with the health of our brains, though of course mental illness (like physical illness) has multifactorial causes, and by no means should we diminish the importance of addressing all the causes in each individual. But let's examine the opposite of the modern high carbohydrate, low fat, constant snacking lifestyle and how that might affect the brain. The opposite of a low fat, snacking lifestyle would be the lifestyle our ancestors lived for tens of thousands of generations, the lifestyle for which our brains are primarily evolved. It seems reasonable that we would have had extended periods without food, either because there was none available, or we were busy doing something else. Then we would follow that period with a filling meal of gathered plant and animal products, preferentially selecting the fat. During the day we might have eaten a piece of fruit, or greens, or a grub we dug up, but anything filling or high in calories (such as a starchy tuber) would have to be killed, butchered, and/or carefully prepared before eating. Fortunately, we have a terrific system of fuel for periods of fasting or low carbohydrate eating, our body (and brain) can readily shift from burning glucose to burning what ar Continue reading >>
Ketosis: Metabolic Flexibility In Action
Ketosis is an energy state that your body uses to provide an alternative fuel when glucose availability is low. It happens to all humans when fasting or when carbohydrate intake is lowered. The process of creating ketones is a normal metabolic alternative designed to keep us alive if we go without food for long periods of time. Eating a diet low in carb and higher in fat enhances this process without the gnawing hunger of fasting. Let’s talk about why ketones are better than glucose for most cellular fuel needs. Legionella Testing Lab - High Quality Lab Results CDC ELITE & NYSDOH ELAP Certified - Fast Results North America Lab Locations legionellatesting.com Body Fuel Basics Normal body cells metabolize food nutrients and oxygen during cellular “respiration”, a set of metabolic pathways in which ATP (adenosine triphosphate), our main cellular energy source is created. Most of this energy production happens in the mitochondria, tiny cell parts which act as powerhouses or fueling stations. There are two primary types of food-based fuel that our cells can use to produce energy: The first cellular fuel is glucose, which is commonly known as blood sugar. Glucose is a product of the starches and sugars (carbohydrates) and protein in our diet. This fuel system is necessary, but it has a limitation. The human body can only store about 1000-1600 calories of glucose in the form of glycogen in our muscles and liver. The amounts stored depend on how much muscle mass is available. Men will be able to store more because they have a greater muscle mass. Since most people use up about 2000 calories a day just being and doing normal stuff, you can see that if the human body depended on only sugar to fuel itself, and food weren’t available for more than a day, the body would run Continue reading >>
The Ugly Truth About Ketogenic Diets
Here's what you need to know... Ketosis occurs when carbs are in such low quantities that your body relies almost exclusively on fatty acid oxidation and ketone metabolism. Ketogenic diets have about 70-75% of your daily caloric intake coming from fat and about 5% from carbohydrates. Ingesting protein above approximately .8 grams per pound is enough to kick you out of ketosis. Ketogenic diets improve body comp, but so does any diet that reduces calories from any source. There is no literature to support that a ketogenic diet is beneficial for promoting increases in muscle mass. Ketogenic diets affect performance negatively. Questions About Ketosis While the ketogenic diet has been used widely and rather effectively in some cases, there's still a lot of confusion about it. What exactly is a ketogenic diet? How does it differ from low carb dieting? Most importantly, at least for the T Nation demographic, is the question of whether ketogenic diets allow you to put on, or at least keep, muscle. Ketosis: What is it? Ketosis is a metabolic state that occurs when dietary carbohydrates are in such low quantities that your body must rely almost exclusively on fatty acid oxidation and ketone metabolism. That sounds simple on the surface, but let's unpack that explanation a bit. To function, your body requires a substantial amount of energy in the form of ATP. So, let's just assume that the average person uses about 1,800 calories per day to create enough ATP to keep him alive (not including any physical activity). Now this is where it gets interesting. You have this thing in your skull called a brain. It uses about 400 or so calories per day and runs almost exclusively on glucose. (There's some evidence it can use small amounts of fat and lactate, but in the big picture it's not Continue reading >>
How To Fix Your Broken Metabolism By Doing The Exact Opposite
We saw last week with the Biggest Loser study that basal metabolism plummets when you lose weight with calorie reduction. As contestants lose weight, they burn a lot less energy – up to 800 calories per day less than before. Some of that is expected, since there is less body tissue to maintain, but nevertheless, these contestants burn far less than expected even taking this into account. Even 6 years later, their basal metabolic rate (BMR) remains depressed, as do the contestants themselves. The story got a lot of coverage, but one thing was consistently missing. How to fix it.That’s what I’ll show you today, and it’s the opposite of what most people expect. So, let’s think about this problem in the context of the 2 compartment model of obesity that we have used before. There are two compartments for body energy. We take calories in as food. This gets stored in the short term as glycogen, or long term as body fat. Glycogen is easily converted to energy (calories out), but body fat, not so much. So we can consider the analogous situation where short term energy is stored in a refrigerator and long term in the basement freezer. Insulin’s role is to direct food into the basement freezer. When there is excess food that can’t be kept in the fridge, insulin directs it to the freezer. This is body fat and manufactured in the liver by the process of de novo lipogenesis. What causes insulin levels to be elevated depends partly on the foods we eat, but also by insulin resistance. Fructose, for example, plays a key role in elevating insulin resistance which will, in turn raise insulin levels. Insulin resistance leads to high insulin levels, which leads to higher resistance in a vicious cycle. That is, it can be self sustaining. So during weight loss, if we don’t ad Continue reading >>
The Biggest Loser Fail And That Ketogenic Study Success
This week, splashed all over the New York Times, was an article about a paper written by Kevin Hall, a senior researcher at the National Institutes of Health. It was published in Obesity and titled “Persistent metabolic adaptation 6 years after ‘The Biggest Loser competition“. This generated a lot of hand-wringing about the futility of weight loss. NYT: After ‘The Biggest Loser,’ Their Bodies Fought to Regain Weight The study, along with another study presented by Kevin Hall seemed to generate more anxiety about the insulin hypothesis being dead. Of course, both these studies fit in perfectly with the hormonal view of obesity and reinforces once again the futility of following the Caloric Reduction as Primary approach. You could review my 50ish part series on Hormonal Obesity if you want a more in-depth view. So, let’s dive in an explain the findings of both of Dr. Hall’s excellent papers. His conclusions, well, let’s just say I don’t agree with them. The studies, though, were very well done. The Biggest Loser Let’s start with the first paper about the Biggest Loser. Essentially, what it did was follow 14 of the 16 Biggest Loser contestants. At the end of the show, they had all lost significant amounts of weight following a Eat Less, Move More approach. Contestants eat about 1000 – 1200 calories per day and exercise like mad people. What the study showed is that basal metabolism drops like a piano out of the Empire State building. It plummets. They are burning about 800 calories less per day than previously. The new paper shows that this metabolic rate does not recover even 6 years later. In other words, if you reduce your ‘Calories In’, your ‘Calories Out’ will automatically drop. This makes sense. If your body normally eats 2000 calories Continue reading >>
Will A Low-carb Diet Ruin Your Metabolism?
There is a lot of confusion within the low-carb community about metabolism. Carbs seem to be a scapegoat that people like to blame when weight loss doesn’t happen fast and easy. If you are following a low carb diet and struggling to succeed, you might believe that all the years you spent eating carbohydrates to your heart's content must have destroyed your metabolism and made you fat. Otherwise, you'd be able to eat like normal folks. Maybe, you are questioning the validity of low-carb diets. You live on the other side of the argument and think that carbohydrate restriction will permanently alter your metabolism, thereby making it impossible to ever return to a well-balanced diet. But what’s the truth? Will eating too many carbohydrates, or eating too few, ruin your metabolism – or not? What is Metabolism? Does hearing about the energy equation make you feel nervous or irritable? Many low-carb dieters feel that way. They don't like hearing about calories or thermodynamics and are quick to jump up and defend the low-carb way of life. Regardless of the truth, most people following a low-carb lifestyle would rather believe in low-carb magic. Afterall, Dr. Atkins told you that you no longer need to worry about calories. You don't have to be afraid of fat. You can eat until you are satisfied. So most people believe that the laws of thermodynamics do not apply to low-carb diets. "Calories don’t matter," they often say. Dr. Eades has tried to set the record straight. But, far too many people still do not want to go outside and drag the energy equation back in from the trash and take a closer look. They’d rather leave it out of sight, pretend it doesn’t exist, and let the myths about starvation mode and damaged metabolisms reign in their lives instead. However, we a Continue reading >>
