Does Keto Raise Your Cholesterol

Long-term Effects Of A Ketogenic Diet In Obese Patients.

Long-term Effects Of A Ketogenic Diet In Obese Patients.

Abstract BACKGROUND: Although various studies have examined the short-term effects of a ketogenic diet in reducing weight in obese patients, its long-term effects on various physical and biochemical parameters are not known. OBJECTIVE: To determine the effects of a 24-week ketogenic diet (consisting of 30 g carbohydrate, 1 g/kg body weight protein, 20% saturated fat, and 80% polyunsaturated and monounsaturated fat) in obese patients. PATIENTS AND METHODS: In the present study, 83 obese patients (39 men and 44 women) with a body mass index greater than 35 kg/m(2), and high glucose and cholesterol levels were selected. The body weight, body mass index, total cholesterol, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, triglycerides, fasting blood sugar, urea and creatinine levels were determined before and after the administration of the ketogenic diet. Changes in these parameters were monitored after eight, 16 and 24 weeks of treatment. RESULTS: The weight and body mass index of the patients decreased significantly (P<0.0001). The level of total cholesterol decreased from week 1 to week 24. HDL cholesterol levels significantly increased, whereas LDL cholesterol levels significantly decreased after treatment. The level of triglycerides decreased significantly following 24 weeks of treatment. The level of blood glucose significantly decreased. The changes in the level of urea and creatinine were not statistically significant. CONCLUSIONS: The present study shows the beneficial effects of a long-term ketogenic diet. It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administerin Continue reading >>

The Cholesterol Myth

The Cholesterol Myth

The Cholesterol Myth There are numerous books and papers being published almost monthly regarding cholesterol and dietary fat. I would encourage you to read the following, and make up your own mind. The first is The Great Cholesterol Myth. It goes someway to explain how cholesterol has been blamed for heart disease, and how this is just so wrong. Jimmy Moore has also written a fabulous book called Cholesterol Clarity. And Nina Teicholz, Investigative Journalist for The New Yorker, The Economist and The New York Times, has spent the last few years researching the unthinkable: that everything we knew about dietary fat is wrong. The Big Fat Surprise – Why Butter, Meat and Cheese Belong In A Healthy Diet. The Cholesterol Myth There are many points raised in these books which are imperative to understand, I’ve written some important take home messages. But please, read for yourself as I cannot do the above books justice in a few bullet points. “We must be our own health advocate. Take control of your health. Find what works for you” Cholesterol is required by almost every cell in our bodies. It is so vital we are able to manufacture it. Cholesterol is made by your liver, brain and almost every cell in your body. Cholesterol is the structure which is the base of all our sex hormones, bile acid and Vitamin D are made from. Cholesterol maintains cell walls, allows cellular communication and transportation of substances. Cholesterol is a poor predictor of heart disease. Half of those with heart disease have ‘normal’ cholesterol levels. Half of those with ‘high’ cholesterol levels have healthy hearts. Most heart attack victims have cholesterol within the “normal” range. It is the carrier of cholesterol (the lipoproteins LDL and HDL) which give a clearer pictur Continue reading >>

What Do You Do If You Get Elevated Cholesterol On A Low-carb Diet?

What Do You Do If You Get Elevated Cholesterol On A Low-carb Diet?

It’s a question I often get. Isn’t a low-carb and high-fat diet bad for the cholesterol? And what if you get an elevated cholesterol on LCHF, what should you do? The good news First the great news: A low-carb high-fat diet usually results in an improved cholesterol profile, indicating a lower risk of heart disease: The classic effect of a low-carb diet on cholesterol is a slight elevation, partly due to an elevation of the good (HDL) cholesterol, indicating a lower risk of heart disease. This especially as the cholesterol profile also typically improves in two more ways: lower triglycerides and larger, fluffier LDL particles. All things that reduce risk of heart disease, statistically. It has also been shown that two years with low-carb, high-fat diet advice results in a reduction of atherosclerosis – people actually got less signs of heart disease. The bad news However, there are also potential problems, even if they are rare. On average the elevation of total and LDL cholesterol is so small that most studies do not even pick up on it. But for a smaller number of people – possibly around 1-2 percent of the population – there can be worrying elevations of LDL and total cholesterol, beyond what can be considered normal. This potential risk is worth taking seriously. It can also be worth taking steps to correct it. I’ve written more about it on the page about potential side effects of low-carb diets: Low Carb Side Effects & How to Cure Them More Continue reading >>

Does A Ketogenic Diet Change Your Lipid Profile

Does A Ketogenic Diet Change Your Lipid Profile

Wrong and outdated health information often causes worry about the healthiness of the ketogenic diet. One of the biggest concerns is: does a ketogenic diet change your lipid profile? In order to tackle and address these concerns, we’ll be covering what lipid profile means, why it’s included in myths about the ketogenic diet and why you don’t need to worry about most of what you’ve been told. Lipids and the Ketogenic Diet The main purpose of the ketogenic diet today is to provide a measurable state of metabolism through nutritional ketosis. There are many benefits of ketosis, including weight loss, better mental clarity, and more energy. These benefits make the ketogenic diet enticing, but what about how it affects lipids in the body? To understand this, let’s discuss what lipids are and the beliefs surrounding them and the keto diet. What is a Lipid Profile? A lipid profile is the measure of fats and fatty substances (lipids) that your body uses as energy. These are usually measured via a lipid panel of blood tests meant to look for any irregularities in your lipid amounts. Lipids include: Triglycerides Cholesterol High-density lipoprotein (HDL, often know as “good,” cholesterol) Low-density lipoprotein (LDL, often known as “bad,” cholesterol) The ketogenic diet raises some concerns around the diet negatively affecting one’s lipid profile and increasing their risks of diseases related to high cholesterol or triglycerides. Let’s take a look at these concerns. Myths About Fat and Cholesterol Below are some of the myths when it comes to the ketogenic diet and lipid profiles. We’re used to hearing many of these due to bad or old science — and we all know the internet is rampant with poor (and sometimes harmful) information. Myth: Cholesterol is bad Continue reading >>

What Impact Can A Ketogenic Diet Have On Cholesterol?

What Impact Can A Ketogenic Diet Have On Cholesterol?

Cholesterol is a class of lipids (or fats) in the body. It is a waxy substance that has a variety of functions such as building hormones (estrogen and testosterone), maintaining the integrity of cell membranes, and aiding in the absorption of vitamins (fat soluble vitamins). Your body gets all the cholesterol needed through internal production from the liver and various other cells of the body (75%) or from dietary sources (25%) (1). Cholesterol is transported in the blood by molecules known as lipoproteins which are composed of fat and protein. Most are familiar with them, as they are what is reported for our health measures…. HDL, LDL, etc. Lipoproteins 101 (Cholesterol) High Density Lipoproteins (HDL), also referred to as “good cholesterol” have two main functions: 1. Transporting cholesterol around the body 2. Collecting cholesterol that is not being used by cells and brings them back to the liver to be recycled or destroyed. As a result, HDL prevents clogging and accumulation of cholesterol in the arteries. Low-density lipoprotein (LDL) also transports cholesterol produced by the liver and cells throughout the body; however, LDL molecules move slower and are vulnerable to being oxidized. When they are oxidized, these molecules can impede cardiovascular function by burrowing into the walls of the arteries. Thus, they get a bad rap and are often referred to as “bad cholesterol”. Even more damaging can be lipoproteins called very low density lipoproteins (VLDL). These particles transport triglycerides in the body, and are more likely than other lipoproteins to clog vessels and impair cardiovascular functions. What is The Impact of a Ketogenic Diet on Lipoprotein Levels? Research suggests that a low-carb, high-fat ketogenic diet may have a clinically-positive Continue reading >>

Ketogenic Diet: Is The Ultimate Low-carb Diet Good For You?

Ketogenic Diet: Is The Ultimate Low-carb Diet Good For You?

Recently, many of my patients have been asking about a ketogenic diet. Is it safe? Would you recommend it? Despite the recent hype, a ketogenic diet is not something new. In medicine, we have been using it for almost 100 years to treat drug-resistant epilepsy, especially in children. In the 1970s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss. What is a ketogenic diet? In essence, it is a diet that causes the body to release ketones into the bloodstream. Most cells prefer to use blood sugar, which comes from carbohydrates, as the body’s main source of energy. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies (the process is called ketosis). Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again. The shift, from using circulating glucose to breaking down stored fat as a source of energy, usually happens over two to four days of eating fewer than 20 to 50 grams of carbohydrates per day. Keep in mind that this is a highly individualized process, and some people need a more restricted diet to start producing enough ketones. Because it lacks carbohydrates, a ketogenic diet is rich in proteins and fats. It typically includes plenty of meats, eggs, processed meats, sausages, cheeses, fish, nuts, butter, oils, seeds, and fibrous vegetables. Because it is so restrictive, it is really hard to follow over the long run. Carbohydrates normally account for at least 50% of the typical American diet. One of the main criticisms of this diet is that many people tend to eat too much protein and Continue reading >>

The Ketogenic Diet And Cholesterol

The Ketogenic Diet And Cholesterol

A common misconception is that because ketogenic diets are high in fat, they must increase cholesterol in your body and clog your arteries. However, much of the recent research shines light on how low-carb diets can optimize your cholesterol levels and in fact improve your heart health. Here we show the most up-to-date research on how different types of cholesterol impact the body and how the ketogenic diet can be a useful tool in maintaining a robust cardiovascular system. Cutting through the Fat: What are Lipids and Cholesterol? Before we can examine the research, we need to understand the roles fat, cholesterol, and carrier molecules called lipoproteins play in the body. Fats, also known as lipids, are a diverse group of molecules with a “non-polar” characteristic that repels water. This means that you if you put a fat such as oil or grease in water they will not mix. In the human body, fats are most commonly found in the bloodstream in one of two forms. The first is triglycerides, a fatty acid that stores energy for later use. These long molecules can be broken down into other fatty acids and glycerol to create fuel for the body. Glycerol can further be broken down into forms of glucose. Elevated levels of triglycerides in your blood can increase your risk of developing diabetes, cardiovascular illnesses, and other life-threatening diseases. [1] The other important class of lipids in the body is a waxy substance called cholesterol. These molecules have a variety of functions in your body such as building hormones including estrogen and testosterone, maintaining the integrity of cell membranes, and aiding in the absorption of vitamins. Your body produces all the cholesterol you need through the liver and other body cells. Cholesterol is also obtained by consuming Continue reading >>

How Keto Diet Can Affect Your Cholesterol Levels

How Keto Diet Can Affect Your Cholesterol Levels

One of the biggest concerns when it comes to following the ketogenic diet is that some people are afraid to try this way of eating simply because they think it can increase their cholesterol and clog their arteries. From the solid scientific studies we will talk about below, a low-carb ketogenic diet is shown to improve your cholesterol levels and can be an incredibly healthy choice. Lipids, Lipoproteins and Their Impact on Health The human body consists of cells and each cell is composed of lipids and proteins. Lipids are a type of fat or oily substance which constitutes the membrane of a cell (1). The two most known types of lipids are triglycerides and cholesterol, which are generated in the liver and found in the bloodstream (2, 3). Lipoproteins are lipid-proteins which are responsible for the chemical change and transfer of lipids in the human body, such as the High-Density Lipoprotein Cholesterol (HDL cholesterol) and the Low-Density Lipoprotein Cholesterol (LDL cholesterol). HDL cholesterol transfers the extra cholesterol from the blood to the liver for removal from the body and is also referred to as “good” cholesterol. LDL cholesterol transfers the cholesterol within the bloodstream to the parts of the body where cell repair is needed and also inside the arteries. It is also known as “bad” cholesterol. Total cholesterol is HDL and LDL cholesterol combined (4). There has been extensive research on whether high cholesterol levels can cause cardiovascular disorders and which type of cholesterol lipoprotein is a valid indicator. An early clinical trial among 3641 men in the US showed that the ratios of total cholesterol to HDL cholesterol as well as the ratio of LDL/HDL cholesterol were significantly better indicators of cardiovascular risk compared to the Continue reading >>

High Cholesterol Meets Ketosis: An Update

High Cholesterol Meets Ketosis: An Update

A couple of years ago I started using the ketogenic diet to manage my blood sugar as a type 1 diabetic and to enhance my athletic performance. I wrote a series of blogs and an ebook to share that experiment because adopting a low carb high fat (ketogenic) diet has become the single most beneficial thing that I’ve done for my diabetes management and my ability to be active in the 20 years I’ve been living at this difficult metabolic crossroads. Eating ketogenic has improved my life and my ability to make photography, climbing and moving around in the outdoors the center of my life rather than fleeing the complications of diabetes. I didn’t expect those posts to take off because I’m not a dietary blogger. I just wanted to share the ups and downs of what I was trying in hopes that it would help other people. One of the major issues I encountered was the sharp increase in my LDL (“bad”) cholesterol and initially I considered abandoning the ketogenic diet because I feared that I was just trading one risk factor for another. If you want to read that post and the comment thread check it out here! I am writing this post to update you since two years have passed and I have found some information that I believe is useful. I also want to clarify my current position on the cholesterol issue and why my LDL is still high and why I’m not letting that fact deter me from eating ketogenic. In fact, I am going to share a couple more blog posts in the future detailing some new experiments I’ve been doing using intermittent fasting and exogenous ketones which has been nothing short of mind-blowing!

How Does A Ketogenic Diet Affect Cholesterol?

How Does A Ketogenic Diet Affect Cholesterol?

Low Carbohydrate diets and the ketogenic diet have a growing amount of clinical trials supporting it. One of the key concerns, as you are probably well aware, is cholesterol. I will edit this answer when I am not on my phone with RCT data, but in short, blood cholesterol is not a simple matter. “Cholesterol” as measured by a VAP test can be broken down into several components. HDL, is the good cholesterol, LDL is the bad cholesterol. That's the simplistic look at it. LDL has different particle sizes, small particles are bad because they can get stuck in the arterial linings, contributing to plaque. Bigger particles don't get stuck as easily, so they are good, and HDL removes LDL particles from the heart and into the liver. There are also triglycerides, or literal fats stored within your bloodstream, An excess of triglycerides is bad for the blood. Cholesterol can only be increased by fats, especially saturated. This is why people fear high fat diets, however what they neglect to notice is that low fat diets lower all of your cholesterol, including HDL, or the good cholesterol. Low fat diets tend to lower HDL more than LDL, and small particles of LDL become more common, possibly due to the scarcity of LDL cholesterol. Triglycerides decrease, or increase by varying amounts, depending on the person. This is because low fat diets need to eat carbs, which transforms into glucose which transforms into glycogen, or a storage form of glucose. The liver then uses glycogen as the primary fuel to create lipids, like triglycerides. The effect varies depending on the diet. This is why ruminants like cows can have extremely fatty meat through eating a low fat, high carbohydrate diet that is rich with fiber. Low carbohydrate diets, such as keto, increase your HDL cholesterol signi Continue reading >>

What To Do If A Low-carb Diet Raises Your Cholesterol

What To Do If A Low-carb Diet Raises Your Cholesterol

Low-carb and ketogenic diets are incredibly healthy. They have clear, potentially life-saving benefits for some of the world's most serious diseases. This includes obesity, type 2 diabetes, metabolic syndrome, epilepsy and numerous others. The most common heart disease risk factors tend to improve greatly, for most people (1, 2, 3). According to these improvements, low-carb diets should reduce the risk of heart disease. But even if these risk factors improve on average, there can be individuals within those averages that experience improvements, and others who see negative effects. There appears to be a small subset of people who experience increased cholesterol levels on a low-carb diet, especially a ketogenic diet or a very high fat version of paleo. This includes increases in Total and LDL cholesterol... as well as increases in advanced (and much more important) markers like LDL particle number. Of course, most of these "risk factors" were established in the context of a high-carb, high-calorie Western diet and we don't know if they have the same effects on a healthy low-carb diet that reduces inflammation and oxidative stress. However... it is better to be safe than sorry and I think that these individuals should take some measures to get their levels down, especially those who have a family history of heart disease. Fortunately, you don't need to go on a low-fat diet, eat veggie oils or take statins to get your levels down. Some simple adjustments will do just fine and you will still be able to reap all the metabolic benefits of eating low-carb. Interpreting cholesterol numbers can be fairly complicated. Most people are familiar with Total, HDL and LDL cholesterol. People with high HDL (the "good") have a low risk of heart disease, while people with high LDL (the " Continue reading >>

Ketogenic Diet And High Cholesterol

Ketogenic Diet And High Cholesterol

I recently got some blood work back and I wanted to share my results in hopes that it may offer some insight to others who may find themselves at the crossroads of the ketogenic diet and high cholesterol. I have been following a low-carb high-fat diet since July and generally speaking I have been really happy with how it has impacted my body composition, athletic performance, energy and blood sugar control. I’ve written an ebook about it (specifically in relation to type 1 diabetes) and I want to be fair and share the challenges that I’m having as well. What I am presenting here is in no way advice or even a solution that I have found for myself–but rather a question that I am working through. I’ve always had elevated cholesterol (last 10 years) and I’ve always prioritized my blood sugar management over cholesterol. Simply put, there are more questions about the risks of cholesterol than the risks of elevated blood sugar, so I focus on the “devil I know”. I got my bloodwork back and found that my total cholesterol is 383 with LDL at 292. My a1c was 6.5. Neither of these individually are what I am shooting for and both in combination are a bit more alarming. Being perfectly honest it feels like a massive failure to be back at this point of reevaluating everything again. It’s hard not to be governed by numbers but it’s not responsible to ignore them either. I declined statin medication and I was told to switch to a low fat diet high carb diet. My blood pressure was 104/84 and I typically have a resting pulse rate of about 60. I immediately did an internet search on the keto diet correlating to elevated cholesterol and found a whole lot of conjecture. There haven’t been conclusive tests done to evaluate the risk of elevated LDL while on a ketogenic diet Continue reading >>

The Straight Dope On Cholesterol – Part I

The Straight Dope On Cholesterol – Part I

I’ve been planning to write at length about this topic for a few months, but I’ve been hesitant to do so for several reasons: To discuss it properly requires great care and attention (mine and yours, respectively). My own education on this topic only really began about 9 months ago, and I’m still learning from my mentors at a geometric pace. This topic can’t be covered in one post, even a Peter-Attia-who-can’t-seem-to-say-anything-under-2,000-word post. I feel a bit like an imposter writing about lipidology because my mentors on this topic (below) have already addressed this topic so well, I’m not sure I have anything to add. But here’s the thing. I am absolutely – perhaps pathologically – obsessed with lipidology, the science and study of lipids. Furthermore, I’m getting countless questions from you on this topic. Hence, despite my reservations above, I’m going to give this a shot. A few thoughts before we begin. I’m not even going to attempt to cover this topic entirely in this post, so please hold off on asking questions beyond the scope of this post. Please resist the urge to send me your cholesterol numbers. I get about 30 such requests per day, and I cannot practice medicine over the internet. By all means, share your story with me and others, but understand that I can’t really comment other than to say what I pretty much say to everyone: standard cholesterol testing (including VAP) is largely irrelevant and you should have a lipoprotein analysis using NMR spectroscopy (if you don’t know what I mean by this, that’s ok… you will soon). This topic bears an upsettingly parallel reality to that of nutrition “science” in that virtually all health care providers have no understanding of it and seem to only reiterate conventional wisdo Continue reading >>
