Questions & Answers

Q: Why does the body make cholesterol, and what is its function?

Cholesterol is produced by the body for structural purposes, such as cell membranes, and plays a role in hormone production.

Q: Why does fasting increase cholesterol levels?

When fasting, the body utilizes fat reserves, which contain triglycerides and cholesterol. The excess cholesterol is either used for repair or eliminated through bile production in the liver.

Q: Should I be concerned if my cholesterol levels increase during keto or fasting?

An increase in cholesterol levels during keto or fasting is typically temporary and not necessarily a cause for concern, especially if other health markers like remnant cholesterol are within a healthy range.

Q: Why is the remnant cholesterol test a better indicator of cardiovascular health?

The remnant cholesterol test considers the remaining cholesterol after subtracting HDL and LDL levels. It provides a clearer picture of cardiovascular risk, especially when insulin and carbohydrate intake are considered.

Q: How can I lower remnant cholesterol levels?

Keeping insulin levels low by reducing refined carbs and sugar intake can help lower remnant cholesterol levels, even if overall cholesterol levels appear high. The body will utilize triglycerides from fat stores, reducing remnant cholesterol.

Q: Why is fasting sometimes recommended before a cholesterol test?

Fasting before a cholesterol test is often performed to eliminate the potential influence of recent food intake on test results. However, this may not accurately reflect cholesterol levels after regular eating, especially if fasting increases cholesterol temporarily.

Q: Can keto and fasting help improve cardiovascular health?

While keto and fasting might temporarily raise cholesterol levels, they have the potential to improve cardiovascular health. Maintaining low insulin levels and reducing remnant cholesterol is essential for overall heart health.

Summary & Key Takeaways

  • The body produces the majority of cholesterol, and dietary cholesterol has less impact on overall levels. Cholesterol is crucial for cell membranes and the production of hormones.

  • During fasting, cholesterol levels can rise as the body taps into fat reserves. However, this increase is not necessarily problematic.

  • The remnant cholesterol test provides a more accurate assessment of cardiovascular health, which can be influenced by factors like insulin and carbohydrate intake.
