I am keto / carnivore because of my heart. Had a bit of a blockage that was taken care of during a heart valve replacement (long story).
After the surgery I did a lot of research in regards to what to eat to reduce heart disease. I found plenty of anecdotal evidence on YouTube and other places.
The one thing that stuck me was that sugar damages arteries. This is something you don’t hear.
When on the keto / carnivore diet your bloodwork will normalize however, LDL cholesterol will go up. I found a study that correlated that with LOWER all cause mortality.
If you are worried about the saturated fat and cholesterol thing… don’t! It’s been a sham from the beginning to sell statin drugs.
If you have any questions, I am more than happy to help. Keep up your journey.
