Low-carb and ketogenic diets are incredibly healthy.
They have clear, potentially life-saving benefits for some of the world’s most serious diseases.
This includes obesity, type 2 diabetes, metabolic syndrome, epilepsy and numerous others.
According to these improvements, low-carb dietsshould reduce the risk of heart disease.
But even if these risk factors improve on average, there can be individuals within those averages that experience improvements, and others who see negative effects.
There appears to be a small subset of people who experience increased cholesterol levels on a low-carb diet, especially a ketogenic diet or a very high fat version of paleo.
This includes increases in Total and LDL cholesterol… as well as increases in advanced (and much more important) markers like LDL particle number.
Of course, most of these “risk factors” were established in the context of a high-carb, high-calorie Western diet and we don’t know if they have the same effects on a healthy low-carb diet that reduces inflammation and oxidative stress.
However… it is better to be safe than sorry and I think that these individuals should take some measures to get their levels down, especially those who have a family history of heart disease.
Fortunately, you don’t need to go on a low-fat diet, eat veggie oils or take statins to get your levels down.
