Plant-based meals require far fewer resources and is cheaper, which means maintaining societal stability when resources are becoming low - as there is more to go around.
A lot of farm land is being used to grow foods for livestock. We could use that land to grow food for ourselves.
> So on a plant-based diet you can't save yourself?
I'd generally go for keto since that is more studied compared to strict carnivore.

But your health will (probably/maybe) be worse. There are ways to make cheap keto (ex: eating 10 eggs/day in my local area).

I believe (not really studied myself, but as with most things in life, I only do enough research on how to choose who to believe, not really KNOW MYSELF, reality is so complex that I don't have enough time to really know, and even if I do have time, I'm often not genetically predisposed to be good at it, so I still dont decide for myself, only who to believe)
that you should do keto or carnivore. Feel free to read or believe the vegan doctors or the keto/carnivore ones. But I've made my choice and I ~mostly have been right in my life, including this. Feel free to become a psychiatrist/psychologist/sports-science and do your studies and bring a better way.
Until then, eat keto/carnivore with the best red meat you can afford. And then worry about the world. And humans are smart enough to fix this particular issue.
> The question wasn't about saving the planet, it was about spending less on food.
My bad. Then my answer is don't save by eating bad food. It will limit you more compared to the extra cash you'll save (unless you're poor and you have no choice).
Try keto diet, or maybe even carnivore. Save yourself first, and then look up into saving the planet.
