Keto Diet and High Cholesterol

Keto Diet and High Cholesterol – Overview

The ketogenic, or keto, diet is a trendy low-carbohydrate, high-fat diet that is extremely low in carbs. Compared to most low-carb diets, it is far more restrictive regarding the macronutrients you can consume.

Carbohydrates, fats, and protein are examples of macronutrients the body needs for good health. They are also the primary sources of calories and energy and make up for the bulk of micronutrients that we ingest.

In the medical community, the term “keto” refers to a metabolic state known as ketosis, which occurs when you limit carbohydrates in your diet.

Your body produces ketones from the fat you consume and the fat stored in your body. Actually, it is a better and healthier way of eating that dates back several years.

The impact of a ketogenic diet on heart health, on the other hand, is less specific. Below, we look at what cholesterol is, the keto diet, and what to include in your diet to maintain good cholesterol levels

What Is Cholesterol, And How Does It Affect Us?

The body contains a waxy, fat-like material known as cholesterol found within the cells and organs. Good cholesterol levels aid in normal cellular membrane and vitamin D formation and improved hormonal levels.

On the other hand, a high cholesterol level can result in heart health problems, stroke, obesity, diabetes, and other health issues.

 There are a few different kinds of cholesterol, each of which has a distinct effect on cardiovascular health and other health outcomes.

Low-density lipoprotein (LDL) cholesterol, referred to as “bad” cholesterol, contributes to the buildup of fatty deposits in the arteries, which increases the risk of heart disease.

The fatty buildup results in a narrowing or blocking of the arteries leading to the development of atherosclerosis. Atherosclerosis increases the likelihood of having a heart attack or a stroke.

High-density lipoprotein (HDL) cholesterol, referred to as the “good” cholesterol, reduces some people’s risk of heart attack and stroke.

HDL cholesterol aids in the removal of some LDL cholesterol from the arteries, which may help reduce the risk of developing heart disease and other health issues caused by high cholesterol levels.

In addition to LDL and HDL cholesterol, your total cholesterol level includes triglycerides, which account for 20% of your total cholesterol.

Even though triglycerides are not a type of cholesterol, they are the most common type of fat or lipid found in your body.

The body converts additional calories from the food you eat into triglycerides, used as energy sources between meals. Combining a high triglyceride level and a high cholesterol level increases your risk of coronary heart disease.

Is The Keto Diet Good For People With High Cholesterol Levels?

The keto diet is diverse, but typically, it limits an individual’s total carb consumption to 5 to 10 percent of the total calories consumed daily. That also translates to about 20 to 50 grams of carbs daily.

Furthermore, the diet allows a fat consumption of 70 to 80 percent of the total calories consumed daily. The other 10 to 20 percent of your calorie intake should come from proteins.

Since the keto diet is extremely high in fat, it raises a question as to whether it will influence your cholesterol levels, either positively or negatively.

Because high cholesterol is associated with an increased risk of heart disease, this is a legitimate issue to ponder, especially for those on a keto diet.

Several studies show that the ketogenic diet can have a positive impact on cholesterol levels, cardiovascular health, and metabolism in the ways listed below:

  • Changes the size of LDL particles which reduces the likelihood of oxidative stress occurring
  • It helps improve the ratio of LDL to HDL cholesterol
  • Raises HDL cholesterol that also assists in counteracting the adverse effects of LDL cholesterol
  • Known to reduce triglycerides, which is beneficial because high levels of triglycerides in the blood suggest an increased risk of stroke and cardiovascular disease
  • Increases the ratio of triglycerides to HDL cholesterol
  • Minimizes insulin resistance and aids in the management of blood sugar levels, especially in comparison to high-carbohydrate diets
  • Aids in the reduction of chronic inflammation
  • Reduces food cravings and calorie intake on an ad libitum basis, thereby assisting in the prevention of obesity
