Is Fasting Good for Cholesterol? Exploring the Link

We see cholesterol, especially low-density lipoprotein (LDL) cholesterol, as a negative factor in maintaining a healthy heart. Having high levels of LDL cholesterol increases the chances of developing heart disease.

According to the CDC, or the Centres for Disease Control and Prevention, approximately 25 million adults in the United States have total cholesterol levels exceeding 240 mg/dL. A whole cholesterol level of 240 mg/dL is very high and indicates an increased risk of heart disease.

In this blog, we will find an answer to the question “Is fasting good for cholesterol?”. We will also learn what is the relationship between fasting and cholesterol management. In addition, several medications are used for effective and frequent treatment results; buy Lipitor Online.


What Is the Need for Cholesterol?

It is a waxy, fatty molecules-like substance that is found in all your body's cells. Your body requires cholesterol to form hormones, vitamin D, and cell membranes. High cholesterol is something that increases the chances of having heart attacks or strokes, but the good news is that it is treatable.

Cholesterol is divided into two main types: 'Bad' cholesterol is called low-density lipoprotein (LDL), while 'good' cholesterol is called high-density lipoprotein (HDL). However, when good cholesterol turns bad, it becomes dysfunctional, contributing to cardiovascular risks instead of protecting the heart.

[Triglycerides - It is a special form of fat that circulates in the blood and is also evaluated. Triglycerides are the main form of fat in the body, both in adipose tissue (where fat is stored) and in the blood.]


Why Do We Have Such High Cholesterol?

The liver manufactures all the cholesterol your body needs. There are both medical and lifestyle factors that can contribute to an increase in blood cholesterol levels.

  • When you consume a diet high in high cholesterol, saturated fats, and trans fats, it could raise your chances of getting high cholesterol.
  • Living with obesity also puts you at a higher risk. In addition to diet, there are other lifestyle factors, such as being inactive and smoking.
  • The influences of your genes decide whether you are more likely to develop high cholesterol. Genes are passed on from parents to their offspring.
  • High cholesterol is caused by a condition called familial hypercholesterolemia, although this is quite rare. This genetic disorder stops your body from getting rid of LDL.
  • Health conditions like diabetes and hypothyroidism also raise your chances of developing high cholesterol and its associated complications.


Foods to Avoid

Dietary cholesterol is found in all of these foods except fruits, vegetables, grains, and legumes. A high-fiber diet is typically high in dietary cholesterol. Cholesterol is located in the following food items that you need to avoid:

  • Eggs, specifically the yolk of the egg.
  • Meat (including beef, hog, lamb, and fowl) in various cuts.
  • Fish and seafood, particularly crustaceans like lobster, shrimp, and crab.
  • Products from milk and cream include cheese, butter, and milk.
  • The liver and kidney are two examples of organ meats.
  • Meats that have been processed are high in fat, such as bacon, sausages, and hot dogs.


Fasting and Cholesterol: What Is the Link?

When we hear about fasting, we often think of weight loss, but did you know that intermittent fasting also significantly impacts our cholesterol levels? Let's dive into the science behind this fascinating link.

Is Fasting Good for Cholesterol?

Let us answer this question “Is fasting good for cholesterol? Yes. Intermittent fasting, also called intermittent energy restriction, refers to different meal timing schedules that alternate between periods of voluntary fasting or reduced calorie intake and periods of non-fasting within a specific timeframe.

Intermittent fasting changes the way our bodies use energy. Instead of relying on glucose, it shifts to using ketones. During fasting, your body starts using stored lipids (fats) for energy. These lipids travel in your bloodstream to the liver and are converted into ketones. But here's the exciting part: how these lipids are arranged influences the type and amount of cholesterol needed for the process.

As a result of this process, your body elevates the levels of HDL (the "good" cholesterol) and decreases the levels of LDL (the bad cholesterol). This change is beneficial for your cholesterol levels and lowers your chance of dyslipidemia, a major contributor to cardiovascular disease.


What Happens with Triglycerides?

It's a similar tale when it comes to triglycerides (TG), with the possible exception that there's greater proof that high TG levels increase the risk of cardiovascular disease.

If you are wondering if fasting affects TG levels. Triglyceride levels are very responsive to dietary changes. However, lowering cholesterol or dietary fat does not help. Instead, it appears that cutting back on carbs is the key influence in lowering TG levels.


The Function of Fatty Acids and Ketone Bodies

Triglycerides are metabolized by the body into fatty acids and glycerol during a fast. To fuel your cells and tissues, your liver processes these fats into ketone bodies. Fasting positively impacts cardiovascular health by influencing the production of essential proteins like Apolipoprotein A and reducing harmful components like Apolipoprotein B. Let’s look at them closely how they work:

  • Apolipoprotein A (apoA-1) is an essential component of high-density lipoprotein (HDL) cholesterol, and it is produced in part through this liver mechanism. The ultimate outcome is improved cardiovascular health due to increased levels of good cholesterol HDL.
  • Apolipoprotein B, the primary protein in low-density lipoprotein (LDL; the nasty kind of cholesterol), declines. This leads to lowered liver triglycerides and lower LDL levels, which is another good result of fasting.


Weight Loss and Cholesterol Improvement

Intermittent fasting not only lowers cholesterol but also aids in weight loss. People tend to consume fewer calories because there's a set time frame for eating. Additionally, producing ketones requires more energy, so your body burns more calories.

If you're overweight or obese, losing the extra pounds significantly improves your cholesterol levels. Weight loss, coupled with the other benefits of fasting, leads to a healthier heart. A number of oral medications are available at the best Canadian online pharmacy to aid weight loss and several other ailments.



Fasting and cholesterol management are closely connected. Is fasting good for cholesterol? Yes, it positively affects cholesterol levels because it helps our metabolism switch from using glucose to using ketones. It results in higher levels of HDL (considered good cholesterol) and lower levels of LDL (regarded as bad cholesterol).

Intermittent fasting further adds the benefit of promoting weight loss to improve heart health. A friendly reminder: It's really important to be careful when starting a fasting routine and to talk to a healthcare professional for guidance.
