I've long considered trying a ketogenic diet, and even gave it a shot once, for two whole days
. But there are a lot of nagging questions, the main one being: who knows who's right in the heart-health debate? On one hand, you have the American Hearth Association saying "saturated fat and cholesterol kills," and on the other, you have every third vlogger and ex-paleo shill claiming nothing could be further from the truth.
I think the only only be satisfied if I could test the diet myself and measure the effects. But a blood test only tells you so much -- side note: apart from cholesterol levels, what else is important? -- and from what I remember, it seems like measuring artery blockage isn't done unless you seem to be at serious risk. Does anyone know, practically, how someone could measure the effect of a high-fat diet on their artery and heart health?
