Considering that many essential nutrients are provided by plants which also provide sugars, you'd have to eat synthetic 'food' in order to avoid all sugars.
> Considering that many essential nutrients are provided by plants
None that I can think of that are proven "essential" in the absence of all carbs. "Phytonutrients" aren't proven essential. Vitamin C ("ascorbic acid") is 100% inessential & optional in the presence of plenty of the (actually essential) ascorbic molecules that are all furnished by fresh meat, including carnitine, creatine etc.
For homo sapiens, there is no essential carbohydrate and no essential plant food. Something to chew on!
Late edit: of course none of this disputes or negates "that many essential nutrients are provided by plants" --- many indeed are. Just none that are essential that aren't furnished in sufficient amounts in a sizable helping of fresh-fatty-mammal-meat =) but the parent didn't even say "only by plants" so not sure why I reacted as if he did
In the end, the one-year project stretched to four years, during which time the two men ate only the meat they could kill and the fish they could catch in the Canadian Arctic. Neither of the two men suffered any adverse after-effects from their four-year experiment. It was evident to Stefansson, as it had been to William Banting, that the body could function perfectly well, remain healthy, vigorous and slender if it used a diet in which as much food was eaten as the body required, only carbohydrate was restricted and the total number of calories was ignored.
> I guess technically you are right, even meat has some carbs in it because muscles hold some glycogen
Near-zero because muscle glycogen is used up upon death in a process called "rigor mortis" (not the case for liver glycogen however AFAIK). The fatty marbling luckily remains.
