I revisited Dr. Westman’s food guidelines for the patients who come to his clinic. ( search for no_sugar_no_startch_diet.pdf ) I’m sure it’s been the guidelines for some decades so well tested on thousands of people. It appears to me he allows for a carnivorous diet save 3 servings of green leafy vegetables per day. After that if you want to eat only meat and/or animal products you’re free to do that and I’m sure more than a few of his patients have done that over the years. If there were ill effects it should have been discovered by now.
It seems to me the self declared carnivore people reject a few cups of leafy greens, not because there is a metabolic benefit but to differentiate themselves from all the other low carbers.
If I reduce the size of my dinner salad, eliminate nuts from my work lunch and substitute with animal products, meat, fish, cheese, heavy cream, etc. it will be carnivore except for a few cups of leafy greens.
Am I missing something?
