A low-carb, high-fat “keto-like” diet may be linked to elevated “bad” cholesterol and doubles the risk of cardiovascular diseases such as blocked arteries, heart attack and stroke, a new study suggests.
“Our study found that self-reported consumption of a diet high in carbohydrates and fat was associated with lower LDL cholesterol – or “bad” cholesterol – and a higher risk of heart disease,” said lead study author Dr. Columbia University’s Heart Lung Innovation Center in Vancouver, Canada, said in a news release.
In the study, researchers stated that on a low-carbohydrate, high-fat (LCHF) diet, 45% of total daily calories come from fat and 25% from carbohydrates. The study was presented on Sunday Annual Scientific Session of the American College of Cardiology with the World Congress of Cardiology.
“The reason for our study came from the fact that we saw patients in our cardiovascular prevention clinic with high blood cholesterol after this diet,” said Ethan in his presentation at the session.
Hypercholesterolemia, or high cholesterol, increases a person’s risk of heart attack or other cardiovascular problems.
“This led us to question the relationship between these low-carbohydrate, high-fat diets, fat levels, and cardiovascular disease. And, despite this, the data on this relationship is limited,” she said.
Using health data from the UK database UK Biobank, the researchers compared 305 people eating a LCHF diet with 1,200 people eating a normal diet and following people for at least ten years.
The researchers found that people on the LCHF diet had higher levels of low-density lipoproteins, known as LDL, cholesterol, and apolipoprotein B. can
The researchers also observed that the total fat intake of the LCHF diet participants was higher in saturated fat and double the consumption of animal sources (33%) compared to those in the control group (16%).
“After an average of 11.8 years of follow-up—and after adjusting for heart disease risk factors such as diabetes, high blood pressure, obesity, and smoking—those on the LCHF diet were more than twice as likely. Several major cardiovascular risk factors “Cardiovascular events, such as blockages in arteries, heart attacks, strokes and peripheral arterial disease that require opening,” researchers found, according to the news release.
The researchers said in the release that their study “does not show a causal relationship between diet and risk of major cardiac events” because it is an observational study, but their findings are “particularly important” for further research. 1 in 5 Americans report being on a low-carb, keto-like or full keto diet.
Ethan said the limitations of the study were measurement errors due to self-reported dietary assessments, the small sample size of the study and the majority of participants being British and excluding other ethnicities.
The study also looked at the long-term effects of following the diet, but most people who follow a keto-like diet follow it continuously for a short period of time.
The majority of participants – 73% – were women, which Ethan said was “very interesting to see, but it supports the literature that women in general tend to follow more dietary patterns, and are more inclined to change their lifestyles.” ”
When asked if there are groups that are unaffected by following the LCHF diet, Ethan said that “it can come down to any LDL elevation” depending on how long people stay on the diet and whether or not they lose weight.
One thing to remember is that every patient responds differently. And so, there is indeed individual variation in response. “What we found was, you know, patients tended to have an increase in their LDL cholesterol levels on average,” she said.
According to most health professionals Current keto dietRestricting carbohydrates causes your body to burn fat for fuel, cutting out healthy foods like fruits, beans, and whole grains. In the keto diet, you limit the amount of carbohydrates to only 20 to 50 per day – the lower, the better. To put that into perspective, a medium banana or apple is around 27 carbs – a full day’s allowance.
Keto is short for ketosis, a state in which your metabolism uses stored fat in your liver to produce ketones for energy. The liver is programmed to take your body’s preferred fuel – carbohydrates – and do just that when it thinks it’s hungry.
The keto diet has been around since the 1920s, when a doctor stumbled upon it as a way to control epilepsy Children with epilepsy Unresponsive to other treatments.
Low-carb diets like keto are heavily reliant on filling you up. At least 70% of the keto diet will be made up of fat; Some say It is more than 90%.
While you can get it from unhealthy fats like avocado, tofu, nuts, seeds and olive oil, the diet allows fats like lard, butter and coconut oil, as well as full-fat milk, cheese and mayonnaise. Eating too many foods high in fat causes the body to overproduce LDL cholesterol, which can build up in the arteries and restrict blood flow to the heart and brain.
