Eat protein, vegetables and fruit (you get your carbs from fruit).
Cut out ALL BS carbs (cereal, breads, chips, tortilla’s, sweets, sugar drinks...).
Cut out most dairy (most people are lactose intolerant to some degree).
Stay away from highly processed food (it’s dead - much of the nutrition is lost, tends to be heavily salted and sugared besides being loaded with preservatives, colors, stabilizers, aromatics).
You have stereo scopic vision for depth perception, like all predators.
You have canine test and incisors for cutting “meat” like a carnivore.
Cave man didn’t have the ability to mix his rice with beans, that he got from a grocery store in December, to get a complete protein.
That said, the best proteins are from fish, then chicken, pork, and finally beef.
You are NOT meant to live on some vegan UN and animal rights group / celebrity approved quack diet.
Before we shipped, trucked, flew, froze, canned, and green housed food, you would DIE if you tried to eat some of these fad diets recommended today where it would have been impossible to feed yourself if you exclude animal products.

“Eat protein, vegetables and fruit (you get your carbs from fruit).”
As to “processed food= evil”, you are just repeating the latest mainstream hysteria. A can of sardine or ham (ultra processed food) is much healthier than a dish of strawberries (”health” food).
A proper diet must be simple, logical and based on facts, not dependent on rules pulled out of the hat (salt is bad, fish proteins are better than beef proteins...) or self contradictory (refined carbs are bad, carbs from fruits or whole grains are good) or trotted out by the latest diet fad (ultraprocessed food is poison).
