Got any sources for your claims? Rather than anecdotal evidence in Facebook groups? Sure, you can lose weight on zero carbs and other fad diets. But does that make it ethical and right? Which by the way, you still don’t have any answers about the ethics of meat-centric diets- such as the terrible environmental effects. Or the high rates of PTSD in slaughterhouse workers. Our first-world, meat heavy diets are nuts. Oh, and by the way, you can be vegan and paleo, keto, etc.
