Carb free vegetables like brassica family, spinach etc contain 100% of everything you need. EVERYTHING
Plenty of people have performed at an elite level on a ketogenic diet. Fred Hatfield for example. There is no reason to eat carbohydrate if you do not wish to and the effect restriction has on your insulin sensitivity has plenty of health benefits. If you wish, I can link plenty of sources and citations for this- there would be pages and pages of them
Agreed with oni here but i can also show citations on a carb rich diet will provide arguably better results, i think the higher Volume the more carbs you need, if its strength bases (low reps, heavy weight, long rest period) then you can get away with a keto approach quite comfortably
