In this video, I talk about why you might have high cholesterol after intermittent fasting, and if it’s okay. You may notice that I’ve gone over some of this information before. But, someone came to me with a question about this, and I want to make sure the message gets to those who need to hear it (or hear it again).

This person was concerned because they were doing intermittent fasting, but yet their cholesterol was still going up. I understand. If you experience high cholesterol while fasting, you could get worried. You don’t want to have a heart attack.

But, really, if you’re doing keto (ketogenic diet) and intermittent fasting, you’re not going to have a heart attack—even if you do experience high cholesterol temporarily.

When you fast, you mobilize your fat. The fat is filled mostly with triglycerides and some cholesterol. Triglycerides are primarily used as energy.

Cholesterol is not used to make energy. But, it’s used to make hormones like testosterone, estrogen, and cortisol (which is your anti-inflammatory hormones). Also, all of the cell membranes in your body need cholesterol. So, your body makes a lot of it.

When you eat more cholesterol, your body makes less. When you eat less cholesterol, your body makes more. There’s a feedback mechanism going on.

Now, this is something very important you need to know about cholesterol:

• Cholesterol acts to repair damage in the body.

But, cholesterol doesn’t just float through the arteries. Blood and cholesterol don’t mix that well. So, it’s put in little shuttle busses of protein (known as LDL, HDL, etc.) to be transported through the body easily.

A lot of the time, after intermittent fasting, you’re going to see a huge drop in triglycerides and LDL. But, you may see a cholesterol spike because it’s being mobilized.

If you do experience a cholesterol spike on keto and during fasting, it’s just the transition. A good test you can do is take your cholesterol and minus your HDL and LDL, and what you will get is your remnant cholesterol.

But, what you really need to know about high cholesterol is that it all goes back to a high carbohydrate diet. When you bring your carbs down, your body stops storing and starts using stored energy as fuel.
