Saturated fat is processed by the liver from Chylomicrons to VLDLs to LDLs in an incredibly taxing process directly responsible for fatty liver disease. No faster way to get diabetes than eating lots of saturated fat and sugar. Both are absolutely horrible and very poorly tolerated by humans, who are apes that evolved eating mostly plants. These are empirical facts. Stop treating food like a religion and just eat a fucking vegetable.
I don’t have a 30 year old book to recommend written by non-scientists, but I am happy to discuss, you know, actual modern science.
