Does Keto Raise Your Cholesterol

Low Carb And Cholesterol – A Case History

Low Carb And Cholesterol – A Case History

Three months ago I had a visit from a 53 year old gentleman who was worried about his health. His name is Peter. He had been gaining weight for some time, his knees were aching and he was having trouble playing his weekly tennis with his old classmates. He told me he had probably put on approximately 55 lb (25 kg) in the past five years. “It all started when I quit smoking” he said Peter was working as an accountant. There was a lot a stress at work, long working days and sometimes he had to go in on the weekends as well. Apart from his weekly badminton, he wasn’t really exercising at all. Although he had quit smoking, he had never really bothered about his lifestyle and was totally uninterested in diet and nutrition. His wife took care of the cooking at home and was trying to limit his intake of calories. She was very conscious about cholesterol and tried to use low-fat varieties. At work however, Peter relied mainly on fast food, sandwiches, sodas, chocolate bars, chips, and an occasional fruit in between. Usually a few beers and some red wine on the weekends, bot otherwise not much alcohol. Peter had suddenly become worried about his weight gain and felt his general condition was slowly becoming worse. He was feeling out of breath. For the first time in his life he was really thinking about his health. He appeared to have suddenly realized that, he himself might have to take action. Peter told me he wanted to try a low carb diet. A friend of his had been getting good results with such an approach, was feeling well and had lost a lot of weight. Peter thought this might be the way for him to go. However, his wife was reluctant. She didn’t like the idea of eating so much fat. She had a history of elevated cholesterol herself, and had been trying to avoid animal Continue reading >>

High Cholesterol On A Keto Diet Should You Be Concerned?

High Cholesterol On A Keto Diet Should You Be Concerned?

As keto and low-carb diets have become increasingly popular, some people who follow this way of eating have noticed a sharp rise in their LDL cholesterol. Understandably, most have become concerned, since elevated LDL is typically considered a major heart disease risk factor. However, the reason for this response - and whether it poses significant health risks – isn't completely understood or agreed upon by experts. This article takes a balanced look at the issue and its potential implications for cardiovascular disease and overall health. What is Cholesterol and Why Do We Need It? Cholesterol is a waxy, fat-like substance that is essential for life. It plays an important role in maintaining the integrity of your body's cells. Cholesterol is used to make hormones like vitamin D, testosterone, and estrogen. Cholesterol is also needed for the production of bile acids that help you digest fat. Your liver, intestines, and other organs produce most of the cholesterol found in your body. In addition, it can be obtained from eating animal foods like meat, cheese, eggs, and butter. How Is Blood Cholesterol Connected to Heart Disease? Historically, elevated blood cholesterol levels have been linked to atherosclerosis, a condition involving deposits of plaque that cause the arterial lining to thicken and potentially impair blood flow to the heart. The process of plaque deposition is complex but involves white blood cells, calcium, cholesterol, and other substances converging at the site of inflamed or damaged arteries. However, cholesterol doesn't travel on its own in your bloodstream. Instead, it's carried in lipoprotein particles, which contain special proteins called apoproteins, triglycerides, fat-soluble vitamins and other compounds in addition to cholesterol. Different ty Continue reading >>

Ep8: High Cholesterol Levels On A Keto Diet Experiments By Dave Feldman

Ep8: High Cholesterol Levels On A Keto Diet Experiments By Dave Feldman

In todays interview I get to speak with cholesterol biohacker, Dave Feldman, about how when some people eat a high fat or keto diet their cholesterol goes up a lot! Dave is a senior software engineer and entrepreneur who has become a leader in understanding how to manipulate high cholesterol levels quickly. Dave started eating a low carb high fat diet back in 2015, to avoid type 2 diabetes and regain control of his health and weight. The LCHF diet was making him feel better. His weight and energy levels were getting better. However, he did a blood test to check his cholesterol and glucose levels to check for changes. Boy were there changes. This was when he saw his diabetes risk markers improved, but he had very high cholesterol levels. Dave falls into a category of people he calls “hyper-responders” to a high fat diet. That means people whose cholesterol goes up instead of down on a low carb or keto diet. (Just like me after adding butter in my coffee) If you are worried about having high LDL levels on a high fat, keto or Atkins diet then this podcast is for you. If you want to know how to reduce your cholesterol without using medication and what foods to eat then this podcast is for you. I discuss with Dave how hyper-responders can be lost for answers which is why his n=1 experiments are so important to understand what is happening. We then go into the results of his experiments and how anybody can try manipulate their own high cholesterol using his Feldman Protocol. Enjoy the episode! Show Notes Highlights of what we talk about during the interview: Special thanks to Dave for joining me on the show. Thanks for Listening! Now it’s time to share your thoughts.

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: 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 >>

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 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 >>

Lipid Changes On A Very-low-carb Ketogenic Diet: My Own Experience

Lipid Changes On A Very-low-carb Ketogenic Diet: My Own Experience

I'd like to preface this blog post by apologizing for its length, including links to several long articles. Also, for anyone who doesn't know me, I'm a vocal and enthusiastic supporter of low-carbohydrate diets, but I always strive to be balanced in my writing. I'm very nonconfrontational and don't like "getting into it" with people who disagree with me. However, I expect I'll receive plenty of negative feedback from this article because of the controversial topic. Cholesterol Results From June 2013 through November 2013 My cholesterol levels have always been higher than average. LDL has ranged from 120s-150s as far back as I can remember, long before I began following a moderately carbohydrate-restricted diet back in 2011. In June of last year, I reported my NMR (Nuclear Magnetic Resonance) LipoProfile results after almost a year of consuming a very-low-carb ketogenic diet (VLCKD) containing less than 50 grams net carb per day. I was very happy with these values and frankly a little surprised that I achieved them while eating delicious, satiating foods. Lipid Profile from November 2013 In November of last year, I had a standard lipid profile done as part of lab work for my annual physical: Total Cholesterol: 300 LDL-C: 160 HDL-C: 128 TG: 56 My numbers had increased, but I wasn't terribly concerned about the LDL-C, since on a few occasions it had been nearly that high in the past. Seeing a total cholesterol of 300 was a bit troubling, but I knew it was partially due to having extremely high HDL (Apparently high levels of some types of HDL can also be problematic, although I didn't realize this at the time). Looking back, although I wasn't tracking my intake online regularly back then, I'm pretty sure I was eating the same or perhaps a little more fat than when I had the Continue reading >>

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 >>

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 >>

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 >>

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 >>

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 >>

Keto And Cholesterol

Keto And Cholesterol

If you’re keto, you’ve heard it before. The single most common response given by people who are not familiar with the ketogenic diet and lifestlye is that you’re going to clog your arteries, get heart disease, and die. I’m asked all the time how keto people should respond to that objection. I’m asked by keto people about what kind of evidence they can use to prove that keto isn’t dangerous. I’ll be honest with you, that irritates me. What irritates me isn’t the fact the keto people are seeking evidence. That’s great. I love that. What irritates me is that keto people feel like they should be playing defense. You don’t owe anyone an explanation or defense of what you choose to eat. Your health is your responsibility and you can only answer to yourself. You don’t owe anyone else an explanation for your food. Okay, so enough about my irritation. Back to the question: What do you say to someone who claims that keto will result in clogged arteries, cardiovascular disease, heart attacks, or death? The first thing I say, in response, is: Why do you think that’s true? The thing is, most people don’t really know WHY they believe that keto is dangerous, they’re just parroting what they’ve heard all their lives. And they have no real basis for their belief. I mean, they have no real scientific basis for their belief. The idea that high levels of cholesterol is dangerous is known as the Diet Heart Hypothesis. This hypothesis was first put forth by Ancel Keys in 1955. It states that eating high levels of saturated fat will increase your cholesterol, and increased cholesterol will clog arteries and cause heart disease. The first part of that hypothesis is correct. The second part is wrong. Eating a lot of saturated fat will increase your cholesterol. So Continue reading >>
