This is a side effect of how many people eating keto diets go all in on meat and cheeses. Vegan keto is possible: https://www.reddit.com/r/veganketo/

Lots of people on ketogenic diets are losing weight. The process of losing weight will naturally increase your cholesterol.

You're right, there are different views on this topic, in particular in the types of cholesterol elevated and decreased.

The issue is the "generally considered harmful." High-fat low-carb diets tend to improve triglyceride profiles. Dietary cholesterol is not the same thing as blood cholesterol levels.

Anecdotally, my father and I discovered separately, in bloodwork unrelated to our individual diets, that a HFLC diet significantly decreased LDL and increased HDL.

The causality of elevated cholesterol and coronary heart disease isn't entirely proven. What we see in studies is mostly correlations. Cholesterol-reducing drugs have been shown to not lower the risks associated with high cholesterol levels, so I do think this is an area where we may not have the complete picture yet.

Dr. Jason Fung has a few interesting figures in his book, citing studies where the consumption of eggs for example decreases risks, kind of fascinating.

People who are born with unusually low cholesterol levels also seem to be essentially immune to heart attacks. I don't have the link to the study handy since I'm on my phone.

Be careful what evidence you accept on this question. There are billion dollar industries doing their best to confuse the issue.

I have always had very normal cholesterol numbers. It gives you a better HDL (good chol) to LDL(bad chol, maybe) ratio and is good for lowering triglycerides (definitely bad chol) which is the worst type of cholesterol. Your information is not true and is a common misconception about the diet.

> It gives you a better HDL (good chol) to LDL(bad chol, maybe)

also try to search "ldl blood test" on r/keto, there are tons of people report much higher ldl after switching to keto.

In my observation there are many contradicting studies about LDL and keto, for example this study's results show significant increase in LDL while on keto: https://www.ncbi.nlm.nih.gov/pubmed/31067015

This one is baffling. LDL "significantly increased" while triglycerides "significantly decreased"? Calories/day not stated; if, say, 3200 kcal, that means 40g of carbs.
