I also am not a fan of Dr Mercola (nor other doctors who jumped on the keto bandwagon without understanding its limitations) but do agree with him that a "high fat keto diet" is not optimal long term. He is evaluating a Review paper of many other studies which indicated the cardiology problems before. https://www.sciencedirect.com/scien...4000410#abs0002

Doctors like Peter Attia (Outlive) evaluated the research 3+ years ago and abandoned Keto diets and fasting except for therapeutic use. Good info in his book on the ideal approach to managing CVD risk and blog posts.


Elevated blood lipids on "keto" are a huge confusing topic, but after ten years of defending my wonky cholesterol results (to my Duke GP) I added more nutrient dense healthy carbs, like vegetables, fruit and NF yogurt, and substituted the heavy cream, high fat cheese, fatty meats, bacon, sausage, pepperoni, pork rinds etc. with healthier choices to improve both my lipid panel and nutrition. My low carb diet is completely satiating for fewer calories with smart substitutions and it easily maintains my goal weight, nutrition and health markers.
