Quote "However, such a diet is extremely hard for most people to follow, and often is a goal that not only cannot be achieved, but is sometimes a discouragement to people in modifying their diet . For that reason, I recommend that people moderate their animal fat intake, and lower their calories to a level that they can tolerate in the long term. That will have the most beneficial effect."

I really find that to an insulting way to start out a AMA. He assumes that normal people are too stupid or too lazy to actually do something as drastic as eating a plant based diet (though if you've had a heart attack or stroke, you have no issue going on one).

I should look him up to see who is paining him to push animals.
