What the Science Says About Keto and Cholesterol
If you’re interested in health and wellness, you’ve probably heard about the ketogenic diet or keto for short. This popular diet involves drastically reducing your carbohydrate intake and increasing your fat intake to put your body in a state of ketosis, where it burns fat for energy instead of carbohydrates.
However, some people are concerned about the link between the keto diet and cholesterol levels. After all, the diet encourages eating foods that are high in fat, which can increase cholesterol levels and raise the risk of heart disease.
In this article, we’ll explore the truth behind the keto diet and cholesterol myth. We’ll look at the science behind the diet, how it affects cholesterol levels, and whether it’s a safe and effective way to lose weight and improve your health.
What Is the Keto Diet?
The keto diet is a low-carbohydrate, high-fat diet that aims to put your body in a state of ketosis. This means that your body is burning fat for energy instead of carbohydrates. The diet typically involves eating foods that are high in fat, such as meat, fish, eggs, dairy products, nuts, and oils, and avoiding foods that are high in carbohydrates, such as bread, pasta, rice, and sugar.
How Does the Keto Diet Affect Cholesterol Levels?
One of the concerns about the keto diet is that it may increase cholesterol levels and raise the risk of heart disease. However, the evidence on this is mixed.
Some studies have found that the keto diet can increase levels of LDL cholesterol, which is often referred to as “bad” cholesterol because it can build up in the arteries and increase the risk of heart disease. However, the diet can also increase levels of HDL cholesterol, which is often referred to as “good” cholesterol because it helps remove LDL cholesterol from the arteries.
It’s important to note that not all LDL cholesterol is the same. There are different types of LDL cholesterol, and some are more harmful than others. The keto diet may increase levels of small, dense LDL cholesterol, which is thought to be more harmful than large, fluffy LDL cholesterol.
Overall, the evidence on the link between the keto diet and cholesterol levels is mixed, and more research is needed to fully understand the effects of the diet on cholesterol.
Is the Keto Diet Safe and Effective?
The keto diet can be safe and effective for some people, but it’s not for everyone. Here are some things to consider before starting the diet:
- The keto diet can be difficult to stick to long-term, as it involves cutting out many foods that you may enjoy, such as bread, pasta, and fruit.
- The diet can cause side effects such as nausea, constipation, and fatigue.
- The diet may not be appropriate for people with certain medical conditions, such as liver or kidney disease.
- The diet may not be appropriate for athletes or people who engage in high-intensity exercise, as carbohydrates are the primary fuel source for this type of activity.
However, for some people, the keto diet can be a safe and effective way to lose weight and improve their health. It may be particularly effective for people who have insulin resistance or type 2 diabetes, as it can help improve blood sugar control.

Conclusion
The truth behind the keto diet and cholesterol myth is that the evidence is mixed. While the diet may increase levels of LDL cholesterol, it can also increase levels of HDL cholesterol, which can have a protective effect on the heart. The keto diet can be a safe and effective way to lose weight and improve your health for some people, but it’s not for everyone.
