I do not eat 99.5% fat. My macros are roughly 75/20/5 f,p,c. I am extremely well nourished and healthy by all medical biomarkers and my ability to climb mountains. If I eat a bunch of sugar, I get seizures. That is just how my brain is wired. I am healing that over time using this diet and using less medication. Just try to call that unhealthy.
Knifegill turned himself around from a chubby, zit covered, limping mess into the hot young stud he is today with this diet. Why does that bother you?
If you choose to trash your body with drugs, booze and cigarettes and then doll out health advice, go right ahead. I just hope that people consider the source before following your advice. Could you climb the world's tallest freestanding mountain without dropping in a wheezing heap by the trail? Not for very long if you keep poisoning yourself. I really don't care what macros you eat. The "Avoid Poisonous Things" part of the PB seems to be missing for you.
