"Q: I was talking to some co-workers and telling them about keto and one of them said that keto is not a long term diet because it is very taxing on the liver. I have read that people maintain ketogenic diets for years but that's all I know. So is it true? Is it not a good idea to remain in ketosis for a long time because it's very taxing for the liver?
A: Any weight lost diet is high fat diet, you literally consume your own animal body fat if you are losing it. Carbs are more taxing for liver. Fructose is the same hepatotoxin as alcohol, but even more dangerous for liver and pancreas, alcohol is made of carbs, but it's fermented carbs. Carbs induce de novo lipogenesis, fatty liver, faster than alcohol.
A: Digested carbs and and amino acids goes straight to portal vein, which means straight to the liver. Digested fatty acids goes to lymphatic system. Think about it. You can make any type of diet rather healthy or devastating. Not all fats are created equal."
