A low-carbohydrate, high-fat diet has been linked to an increased risk of severe cardiovascular events, according to new study.
According to recent study, a ketogenic diet that is rich in fat and low in carbohydrates may quadruple the risk of cardiovascular events including heart attacks, strokes, and arterial blockage, as well as be linked to raised levels of “bad” cholesterol.
The primary study author, Dr. Iulia Iatan, of the Healthy Heart Program Prevention Clinic, Sao Paulo Hospital, and The Cardiopulmonary Innovation Center of the University of British Columbia, which is based in Vancouver, Canada, stated in a press release, “Our study found that regular consumption of low-carbohydrate and high-fat self-reported diets is associated with elevated low-density fat cholesterol (or “bad” cholesterol) levels and increased risk of heart disease.”
Christopher Gardner is a medical research professor at the Stanford Prevention Research Center. “This study provides an important contribution, scientific literature, and suggests that the harms outweigh the benefits,” Gardner said. Stopher Gardner mentioned doing a clinical experiment including the ketogenic diet. Gardner did not work on this research project.
According to Gardner, “Rising LDL cholesterol should not be considered a negligible side effect of a very low-carbohydrate diet (VLCD) or a ketogenic diet.” He made the point that those with greater blood levels of ketones had a higher risk of cardiovascular disease when compared to those on a regular diet.
According to the study’s definition, a low-carb, high-fat (LCHF) diet consists of 25% of daily calories from carbs and 45% of calories from fat. The research was presented on Sunday at the World Congress of Cardiology and the American College of Cardiology’s annual scientific meeting.
“The basic principles of our research come from the fact that in our cardiovascular disease prevention clinic, we will see patients with severe hypercholesterolemia follow this diet,” Iatan said in the opening remarks of the conference.
A person with high cholesterol, or hypercholesterolemia, is more likely to have a heart attack or other harmful cardiovascular events.
This raises our curiosity about the connection between blood lipid levels, cardiovascular illnesses, and these high-fat, low-carb diets. The information on this connection is so scarce despite this, the speaker said.
Researchers examined the diets of 1,200 normal dieters and 305 LCHF dieters using health data from the British database UK Biobank, which monitored individuals for a minimum of 10 years.

Researchers discovered that those following high-fat, low-carb diets eat twice as much animal product as those following a typical diet.
Researchers discovered that those following the low-density lipoprotein, or LDL, diet had elevated levels of cholesterol and apolipoprotein B. Low-density lipoprotein cholesterol can be coated with apolipoprotein B, a protein that may predict heart disease more accurately than greater amounts of low-density lipoprotein cholesterol.
Researchers also found that individuals in the LCHF diet consumed more saturated fat overall (33%) and twice as much animal source fat (16%) as the control group.
Other heart disease risk variables (diabetes, hypertension, diabetes, diabetes, etc.) have been adjusted after an average of 11.8 years of follow-up. Obesity and smoking combined with low-calorie, high-fat diets increase the risk of almost twice as many significant cardiovascular events, including peripheral arterial diseases, heart attacks, strokes, occluded arteries, and the need for open stent surgery.” The news release states that the researchers discovered that.
As an observational study, the researchers stated at the press conference that their findings “can only show the relationship between diet and the increased risk of major heart events, not causality.” Nevertheless, given that approximately one-fifth of Americans report following a low-carb, ketogenic, or total ketone diet, their findings warrant additional research.
The majority of participants in the research are British, eliminating members of other ethnic groups, and measurement mistakes when self-reporting dietary assessment are among the study’s shortcomings, according to Iatan.
The research also looked at the vertical effects of adopting this eating pattern, and found that most ketone eaters do so sparingly for brief periods of time.
Seventy-three percent of the participants are female. Iatan said this as “interesting, but it also supports the existing literature that women generally tend to follow more dietary patterns and are more interested in changing their lifestyles.”
Iatan said that how long someone goes on a diet and if they lose weight “can offset any increase in LDL” when asked whether the LCHF diet won’t hurt any group.
It is crucial to keep in mind that every patient responds differently. As a result, there are variances in responses among people. We discovered that low-density lipoprotein cholesterol levels often increase,” the spokesperson said.
Expert in lifestyle medicine Dr. David Katz said, “There are many methods that can be combined into an LCHF diet, and their effects on blood lipids or heart events are unlikely to be the same.” He did not take part in the research.
But, he said, “In this study, the LCHF diet is related to side effects, which is a realistic examination of those who use this diet just because of the epidemic.”
According to the majority of medical professionals, a trendy ketogenic diet limits the ability of carbs to burn fat for energy, which means that less whole grains, fruits, and legumes are consumed. You may only have 20 to 50 grams of carbs per day on the keto diet; the less, the better. Conversely, a medium-sized apple or banana has roughly 27 carbs, which is the daily allowance.
The primary supply of fiber in the diet, as well as the primary source of several vital minerals, phytochemicals, and antioxidants, must be removed in order to achieve ketosis. Many medical specialists are concerned about this because they think that ketogenic diets or VLCDs are bad for long-term health,” Gardner added.
The term “keto” is short for “ketosis,” a metabolic state that develops when your liver starts converting fat stores into energy-producing ketones. Your body’s liver will take over when it senses hunger and is unable to get glucose, which is its preferred fuel.
Since a doctor unintentionally discovered ketosis in the 1920s to help control seizures in epileptic youngsters who were not responding to conventional therapies, ketoshas been around.
Keto and other low-carb diets mostly depend on fat as a filler. Fat makes up at least 70% of ketogenic meals, and others estimate that percentage to be as high as 90%.
The diet permits saturated fats like lard, butter, and coconut oil as well as whole milk, cheese, and mayonnaise, even if you may get all the fat from healthy unsaturated fats like avocado, tofu, nuts, seeds, and olive oil. Consuming a lot of food rich in saturated fat can cause the body to produce more low-density lipoprotein cholesterol, which will build up in the arteries and impede blood flow to the heart and brain.
Diet Battleground: In ketone versus Mediterranean, who prevails?
In a corner: Nutritionists love the well-known Mediterranean diet for its medicinal benefits. Rival: The well-known ketogenic diet is well-known for minimizing daily carbohydrate consumption.
Advocates of ketone compounds claim that this diet would decrease hunger, burn belly fat, and enhance mental acuity during the first days of “ketone influenza,” which is a state of physical pain, exhaustion, and fogginess. Studies indicate that ketonese users may at least temporarily lower their blood sugar levels.
The Mediterranean diet has been shown to lower the risk of diabetes. In addition to weight reduction, strong bones, heart health, and a higher life expectancy, other conditions include excessive cholesterol, glucose, dementia, memory loss, depression, and breast cancer.
Thirty-three prediabetic or diabetic individuals were required to follow one of the two diets for three months in order to compare them throughout the pandemic in a new control clinical experiment. Participants follow their own diet plan after receiving a nutritious keto-based or Mediterranean cuisine for the first four weeks of each diet.
The patients’ weight, blood sugar levels, cardiovascular risk factors, and dietary compliance were all observed by the researchers. When the final bell rings, which weight reduction strategy is still in effect?
Harvard School of Public Health and Harvard School of Medicine professor of epidemiology and nutrition Dr. Walter Willett stated: “Both diets can improve blood sugar control to a similar extent, and the weight loss of the two groups is similar.” He didn’t take part in the research.
The Mediterranean diet, however, was clearly superior when researchers looked at how these two diets affected blood lipid levels, which are the cause of heart disease, according to a study that was published in the American Journal of Clinical Nutrition on Friday. The American Journal of Clinical Nutrition, published on Friday.
This research monitors triglycerides, also referred to as “bad” cholesterol and low-density lipoprotein (LDL), which is another kind of blood fat that contributes to arteriosclerosis.
The dean of the nutrition department at the Chan School of Public Health at Harvard University, T.H. Dr. Frank Hu, did not take part in the research. He stated: “The ketogenic diet has significantly increased by 10% of low-density lipoprotein cholesterol, while the Mediterranean diet has reduced low-density lipoprotein cholesterol by 5%.”He stated absurd things. “There is a significant difference between the two diets, which may have long-term consequences for cardiovascular diseases.”
The research discovered that although triglycerides are lowered by both diets, the ketone diet had a greater overall impact. Ridiculously, however, raising bad cholesterol is more significant than decreasing triglycerides.
“High-density lipoprotein cholesterol is a more powerful and more important risk factor for cardiovascular disease than triglyceride levels,” he said. Therefore, I believe the primary issue is the possible long-term implications of ketone on cardiovascular illnesses, even if both sides are rather good in controlling blood glucose in the short term.
“I strive to give each diet my best shot.”
Ketone advocates claim that it is a rapid weight loss aid. It induces a condition of ketosis in which the body starts using fat reserves for energy. But the amount of carbs consumed each day has been drastically lowered to 20–50 grams in order to enter ketosis. About 50 grams make up a cup of cooked rice.) Increasing your carbohydrate intake will cause you to exit ketosis.
Hu said that because carbs make up 50% of the average American diet, it is advisable to limit carbohydrate consumption to 50 grams. considerably decreased. People find it challenging to sustain this. It is “a huge reduction” that the intake is less than 50 grams. People find it difficult to sustain that.
Most people think of the ketogenic diet as a “meat” diet, piling their plates high with whole dairy products, bacon, sausages, and other meats high in saturated fat, all of which may cause chronic illnesses and inflammation.
Christopher Gardner, the study’s author and a professor of medical research at the Stanford Prevention Research Center, said that the research used a “well-designed ketogenic diet” that prioritized non-starchy vegetables and limited the amount of high-protein food.
“I make an effort to give each diet my best shot. “I didn’t try to make it into inferior Mediterranean and high-quality keto or inferior keto and high-quality Mediterranean,” said Gardner, who is also the head of Stanford University’s Nutrition Research Group.
Except for a limited quantity of berries, the ketogenic diet forbids consuming any grains, legumes, or fruits. On the other hand, the Mediterranean diet places a strong emphasis on include whole grains, nuts, seeds, beans, lentils, fruits, and vegetables on your plate. With the exception of a few berries. Nonetheless, the Mediterranean diet places a strong emphasis on loading your plate with healthy grains, legumes, beans, nuts, and seeds.
According to Gardner, both diets hold the belief that “we eat too little vegetables and too much added sugar and refined grains.” Thus, the overall goal of the research is to determine whether or not it is beneficial to avoid eating fruits, whole grains, and beans while using ketogenic goods after you have followed everyone’s recommendations.
According to Dr. Shivam Josh, an assistant professor of clinical medicine at New York University’s Grossman School of Medicine, “the intake of fiber is incredibly low” and “people in the ketone-base stage also have a reduced intake of thiamine, vitamin B6, C, D, E, and phosphorus” in addition to an increase in bad cholesterol. He didn’t take part in the research.
The omission of fruits and whole grains from the ketone group raises questions about potential long-term health repercussions, even though these foods have significant health advantages.” Willett said. health implications,” Willett said. “Many individuals find it difficult to continue to a ketogenic diet for a long period.” Furthermore, he said, “A lot of people find it challenging to stick to a keto diet over the long term.”
Actually, the majority of participants in the research abandoned the ketogenic diet once it was over.
Ketones were requested to be sent home. Gardner said, “They have a health educator to assist them. But the onslaught! When this portion of the trial ends, the majority of participants quit the ketogenic diet nearly quickly, while many Mediterranean dieters continued to follow this eating pattern at that point.
What is this study’s main takeaway?
“The most important message for me is that strict restrictions on some healthy carbohydrates are not necessary to improve blood sugar control and cardiac metabolism,” Hu said.
You may prepare a highly healthy vegetarian diet, a somewhat low-carb diet, or a Mediterranean diet. Individuals who have diverse dietary preferences make various decisions.”
