The keto diet and heart disease

Is the keto diet safe for heart patients

The ketogenic diet is low in carbohydrates and high in fats, including animal fats, butter, eggs, nuts, and cheese. Researchers have found that a ketogenic diet reduces inflammation and oxidative stress in heart disease patients. Additionally, the ketogenic diet may have adverse effects on heart health.

The following article discusses the risks and facts associated with the keto diet on heart disease. 

Heart disease and the ketogenic diet

Some keto followers boast about their ability to consume butter, eggs, and animal fats. People with heart disease, those at risk for it, or those concerned about their heart health generally may find it difficult to decide whether the keto diet Рwhich consists of at least 70 per cent fat and very few carbohydrates depends on how it practices Рis right for them. 

Many experts believe that high fat intake is not heart-healthy, even though it may have some benefits. Particularly processed foods and animal products contain fats that contribute to high cholesterol levels.

Generally, a keto diet can be tried under the supervision of a doctor (ideally a dietitian) who is familiar with ketosis. Heart disease can occur if you aren’t closely monitored by a medical professional. 

Cardiologists tend not to recommend the ketogenic diet because it can lead to heart problems. 

The keto diet’s effects on heart health

A keto diet can help lose weight, control blood sugar levels, lower triglyceride levels, and increase HDL (good cholesterol). 

A ketogenic diet involves eating fewer carbohydrates than usual. Healthy carbs such as milk, fruit, and whole grains should replace unhealthy carbs like sugary drinks, soda, and white bread.

Since keto diets cut carbs, they don’t automatically prevent heart disease. It can increase your risk of heart disease if you are not closely monitored by a medical professional.

There has been a correlation between the keto diet and higher levels of LDL (bad cholesterol), but the results aren’t consistent across studies. Diets high in saturated and trans fats seem to increase LDL levels. Furthermore, carbohydrate-restricted diets link to an increased risk of atrial fibrillation.

Keto diets are also associated with a higher mortality rate. Animal-based fats were found to have the greatest effect when used in place of carbohydrates. The replacement of carbohydrates with plant-based fats, on the other hand, improved mortality.

Choose plant-based foods rich in unsaturated fat or over-processed foods high in saturated or trans fats to reduce the risk of heart disease while following a ketogenic diet.

Recommendations for the Keto diet for heart patients

Some patients may benefit from a ketogenic diet, but others may experience negative effects. Due to the potential dangers of the keto diet for people with heart disease, general prohibitions apply to the keto diet.

The following recommendations are for the patients suffering from heart disease:

  • Consume a healthy diet consisting of complex carbohydrates, lean proteins, and unsaturated fats.
  • Avoid processed foods.
  • The best fruit or vegetable is fresh.
  • It is also helpful to control portions.
  • Consuming less red meat and more fish.
  • Cutting back on simple carbohydrates, saturated fat, sugar, and trans fat.
  • Sodium can replace with vinegar, herbs, and spices.

Natural options for ketone

While on a keto diet, we offer two natural, safe ways to create ketone bodies. 

  • Sleep induces ketosis naturally, so the first step is to sleep more. 
  • You can also reduce calories through intermittent fasting, though your doctor will still need to monitor your progress. 

Before beginning a new diet, discuss the plan with your doctor.


Carbohydrates are limited in the keto diet, but fats are abundant. While it may have some benefits, such as weight loss and lowering blood sugar levels, it also has some negative effects, especially on heart health, as it is related to high cholesterol levels. It is best to consult with your doctor before beginning this diet.
