Thank you for being a voice of reason in all this. When this ketosis madness ends and we go back to eating plant based like our ancestors did the world will be a better place with healthier humans and no factory farms.
I agree with the poster that a high carb/low fat diet can also be pretty healthy, but you pretty much do have to do one or the other.
Both approaches are difficult, because the food supply/industry isn't really setup for it. There are a ton of unhealthy vegan meals in vegan restaurants as well, where they load up on refined sugar and not as many plants.
They keto stuff isn't madness though. It's just a different approach and it works for some people.
