This is a no brainer.

There are essential fatty acids and amino acids.

No essential (edible) carbs. Ask people 10-30 years on keto carnivore who are a picture of Health and haven't eaten a skngle carb nor veggie in Years /decades.

No, we don't need fiber either.

Then go talk to low/no fat vegans who have gone crazy from myelin sheet demyelination and lack of cholesterol for their brain, sex hormones and exercise recovery. Or justnplain deficient EFAs.

High fat and high carbs is the no man's land that will kill all (eventually), although young athletes can get away with it for a couple of decades, if they burn a lot of calories. Very taxing on the cell metabolism though (you age faster).

And yes, I've tried also both, and feel now stupid for trying out low fat and not doing my due diligence first.
