What to do if a Low-Carb Diet Raises Your Cholesterol
Medical Conditions That Can Raise Cholesterol
It’s also important to rule out medical conditions that can cause elevated cholesterol. These really don’t have anything to do with the diet itself.
One example of that is reduced thyroid function. When thyroid function is lower than optimal, Total and LDL cholesterol can go up (12, 13).
Another thing to consider is weight loss… in some individuals, losing weight can temporarily increase LDL cholesterol.
If your levels go up at a time when you are losing weight rapidly, you may want to wait for a few months and then measure them again when your weight stabilizes.
It’s also important to rule out a genetic condition like Familial Hypercholesterolemia, which afflicts about 1 in 500 people and is characterized by very high cholesterol levels and a high risk of heart disease.
Of course, there are many subtle genetic differences between us that can determine our responses to different diets, such as different versions of a gene called ApoE (14).
Now that all of that is out of the way, let’s take a look at some actionable steps that you can take to bring those cholesterol levels down.
Bottom Line: Make sure to rule out any medical or genetic condition that may be causing you to have high cholesterol.
Remove Bulletproof Coffee From Your Diet
“Bulletproof” coffee is very trendy in the low-carb and paleo communities.
It involves adding 1-2 tablespoons of MCT oil, coconut oil, or butter into your morning cup of coffee.
I haven’t tried it myself, but many people claim that it tastes delicious, gives them energy and kills their appetite.
Well… I’ve written a lot about coffee, saturated fat, butter and coconut oil. I love all of them and think they are very healthy.
However, even though “normal” amounts of something are good for you, it doesn’t mean that massive amounts are better.
All the studies showing that saturated fat is harmless used normal amounts… that is, amounts that the average person consumes.
There is no way to know what happens if you start adding massive amounts of saturated fat to your diet, especially if you’re eating it instead of other more nutritious foods. This certainly isn’t something that humans evolved doing.
I’ve also heard reports from low-carb friendly docs (Drs Spencer Nadolsky and Karl Nadolsky. They had low-carb patients with massively increased cholesterol whose levels normalized when they stopped drinking bulletproof coffee.
If you drink bulletproof coffee and have cholesterol problems, then the first thing you should do is try removing this from your diet.
Bottom Line: Try removing bulletproof coffee from your diet. This alone may be sufficient to solve your problem.
Replace Some Saturated Fats With Monounsaturated Fats
In the largest and highest quality studies, saturated fat is not linked to increased heart attacks or death from heart disease (15, 16, 17).
However… if you have problems with cholesterol, then it is a good idea to try to replace some of the saturated fats you are eating with monounsaturated fats.
This simple modification may help to bring your levels down.
Cook with olive oil instead of butter and coconut oil. Eat more nuts and avocados. These foods are all loaded with monounsaturated fats.
If this alone doesn’t work, then you may even want to start replacing some of the fattymeat you are eating with leaner meat.
I can’t emphasize olive oil enough… quality extra virgin olive oil has many other benefits for heart health that go way beyond cholesterol levels.
It protects the LDL particles from oxidation, reduces inflammation, improves the function of the endothelium and may even lower blood pressure (18, 19, 20, 21).
It is definitely a superfood for the heart and I think anyone at risk of heart disease should be using olive oil, no matter whether their cholesterol is high or not.
It is also important to eat fatty fish that is high in Omega-3 fatty acids, at least once per week. If you can’t or won’t eat fish, supplement with fish oil instead.
Bottom Line: Monounsaturated fats, like those found in olive oil, avocados and nuts, may have cholesterol lowering effects compared to saturated fats.
Drop The Ketosis and Eat More Fiber-Rich, Real Food Carbs
There is a common misunderstanding that a low-carb diet has to be ketogenic.
That is, that carbs should be low enough for the body to start producing ketones out of fatty acids.
This type of diet appears to be the most effective for people with epilepsy. Many people also claim to get the best results, mental and physical, when they’re in ketosis.
However… more modest carb restriction can still be considered low-carb.
Although there is no clear definition, anything up to 100-150 grams per day (sometimes higher) can be classified as a low-carb diet.
It is possible that some individuals see cholesterol increases when they’re in ketosis, but improve when they eat just enough carbs to avoid going into ketosis.
You can try eating 1-2 pieces of fruit per day… maybe a potato or sweet potato with dinner, or small servings of healthier starches like rice and oats.
Depending on your metabolic health and personal preferences, you could also just adopt a higher-carb version of paleo instead.
This can also be a very healthy diet, as demonstrated by long-living populations like the Kitavans and Okinawans, who ate a lot of carbs.
Although ketosis can have many incredible benefits, it is definitely not for everyone.
Other natural ways to lower cholesterol levels include eating foods high in solublefiber or resistant starch, and taking a niacin supplement.
Exercising, getting better sleep and minimizing stress levels can also help.

None of the advice in this article should be considered as medical advice. You should discuss this with your doctor before making any changes.
Keep in mind that I am NOT suggesting that saturated fat or low-carb diets are “bad.”
This is only meant as a troubleshooting guide for the small subset of people who have cholesterol problems on a low-carb and/or paleo diet.
I have not changed my mind about low-carb diets. I still eat a low-carb diet myself… a non-ketogenic, real food based low-carb diet with about a 100 grams of carbs per day.
At the end of the day, low-carb diets are still incredibly healthy and the benefits FAR outweigh the negatives for most people, but a subset of individuals may need to make some adjustments in order to make the diet work for them.
