Avoiding meat is good for losing muscle but it's not good for the brain.
If you know what kinds of veggies to eat, satisfying your fat requirement isn't that hard. One food that is good for fat content is the avocado.
Bacon > Avocado
I liked bacon back when I used to eat pork, which hasn't happened since the '70s but I never liked avocado in any form.
My neighbor nicely brought me some homemade pork pie, noting it was an old French-Canadian recipe.
I don't know what to do with it.
