I believe you would be downvoted less harshly if you provided a few reputable sources to back your statement.
A huge part of identity for some people is based on the knowledge that they're living on a healthy plant-based diet. It turns out that said diet is less healthy than subsisting on bacon grease.
This causes cognitive dissonance. Cognitive dissonance causes knee-jerk downvotes.
Citations? How about the study spelled out in the article?
The vegetarian thing does not folow. Just because keto/atkins/paleo works, doesn't mean anything else works. Nothing is better than the low calorie diet.
I offer up the reddit link for anyone interested in the mechanics of HFLC.
There are animals that eat plants rather than other animals: they are called herbivores. Herbivores somehow develop muscles.
We can't eat exactly like herbivores. Herbivores eat grass and leaves in huge quantities and have the digestive system for it: they can get enough protein and overall calories that way.
Still, we can achieve a given number of calories and a desired fraction of them from protein and fat, using vegetable sources.
Here's a citation against your assertion.
