People must be really out of touch with what healthy food is to switch to a meat only diet. Eat plenty of plants and a little bit of meat, just like our ancestors did, and most importantly don't eat too much, it is easy as that.
Don't fuck up the planet because you think you can only maintain a healthy weight by eating grass fed burgers all the time.
In 20 years we will look back at fad diets like meat-only and keto and make jokes about it.
While elimination diets of any kind are likely ill advised for the long term if your ancestors were inuits, eskimos, chukcha or many other ethnic groups that live in arctic and sub-arctic environment that have not developed agriculture their diet would and is primarily an animal product based with fat constituting the majority of your daily calories especially during winter and even during the summer days the diet lacks any substantial calories from plant based sources if it has any at all.
What? You mean keto practitioners aren't following a strict vegan diet of avocados and processed soy protein? /s
More seriously, though, in fewer than 20 years, meat substitutes will be ubiquitous and people will tend towards sun-fed burgers (if for no reason other than cost).
I mean the keto diet in general. In 20 years I expect to watch a future version of a nostaligia show ("Remember the 2010's?") by having it beamed straight into my visual cortex, and in this show they will make jokes about keto & meat-only diets, and other stupid fads.
Besides your personal opinion, I see no reasons cited to bash keto. There is good data on supporting its health effects. Any possible effects on "the planet" are orthogonal to its healthiness.
