So, fat is bad. Carbs are bad. Meat is bad. Assuming you eat calories (ie leafy vegetables are not a large source of calories), what are you left with? Plant based low fat, low carb lean protein? Peanuts are high in fat. Beans are high in carbs. There’s like nothing you really should eat.
I think I read what would our poor great-great-grandparents think of the food we eat today?
What did they eat, meat rarely (they couldn't afford it all the time), mostly vegetables (mostly home grown), salad-stuff, beans, maybe fruit and the odd nut.
Maybe going back to this direction, is the way we should be leaning.
You should eat a diversified diet and with moderation. All of those are not necessarily bad. Take peanuts for example, they are a great tool to reach certain goals. But eating only peanuts every day would make you ill quickly.
