Here’s a quote from an interesting article on reddit:

Given the evidence, I am greatly annoyed that people still consider fat unhealthy. There are no documented adverse affects of a high fat diet when carbs are removed. It is mostly hearsay and pontification of supposed experts.

That’s from Diary of an Unknown Physicist

I have had a few people comment that the high fat and high cholesterol of this diet are dangerous. This is only one man’s experiment, but there are others online that confirm fat isn’t bad.
