I want to hear about it, don’t stop.

I’d hope people understand that it’s your first-person experience and not a decree going out to the entire population.

Julia,

I'm a keto-friendly cardiologist and a skeptical cardiologist (www.theskepticalcardiologist.com)

As such, I know that for many people a keto-diet is there pathway to success at weight management and all the cardiovascular benefits that accrue when one achieves sustained weight loss. However, perhaps 15% of those going full Atkins type keto have a marked rise in apo B/LDL. It's possible that the marked weight loss from a keto diet by eliminating diabetes, improving HDL/trigs, lower inflammation could outweigh such increases and not increase the risk of atherosclerotic disease. We need more data to know that.

You wrote "I had a CAC test done in Chicago, about 10 years ago, when I declined to go on statins. My score was 3. It’s true that the only good score is 0. But 3 is not terrible. I will be interested if it is higher than 3. If it is, I may have to modify my KLC lifestyle to have less saturated fat in it. This will be hard for me. I like my saturated fat. It keeps me feeling full."

A couple of comments, if I may:

1. CAC score always goes up. Yours will be significantly higher. A score of for a 55 year old white female is at the 77th percentile (I'm not sure what your age was 10 years ago but took a stab) 77th% means you were higher than 3/4 of women your age and at higher risk for ASCVD. A score of 3 for a 65 year old white female is at 54th%, close to the average and doesn't alter risk. I predict your current CAC will be at the same percentile rank of your prior one.so unlikely to change the calculus.

You can plug all your numbers into the online MESA calcium calculator to see your 10 year risk with and without the CAC score.

2. The evidence that switching from saturated fat to unsaturated fat reduces ASCVD risk is very weak. The evidence for statin or other lipid-lowering therapy reducing ASCVD risk is very very strong. You mentioned you really wanted to avoid taking a statin. I suspect this is because there is a strong anti-statin bias in the keto community which propagates misinformation on statins. These are arguably the safest and most life-saving medications that modern science has invented.

If you start one your apo B and LDL will drop like a rock and you can continue eating the diet that you feel most comfortable with.

Here's the page on my blog that summarizes all I've written on statins.It addresses statin denialists, safety, and how to start if you are hesitant (https://theskepticalcardiologist.com/category/statin-drug-therapy/)
