A Zero-Carb Diet or No Carb Diet is a misnomer. The goal is to get as close to no carbs as possible while on a ketogenic diet, not to never eat a carb. This is a very difficult diet because everything you eat has to be monitored and virtually everything has to be homemade.
In my opinion, this is a fad / competitive diet just for the novelty of saying you are on a “Zero/No Carb diet”. Anyone that is trying to lose weight via a keto diet should strive to eat the lowest number of carbs they can every day. Technically, the diet is considered as safe as regular keto diets because your body does not need carbohydrates to survive.
Theoretically, you could eat zero carbs every day and not have any negative consequences. I chose those words specifically, because the reality of a zero-carb diet is not really possible outside of a medically supervised study (which I doubt will ever be done).
The reason is pretty simple. In order to eat absolutely no carbs, you would have to give up almost all food with nutritional value. Yes, you would still be able to eat meats and simple proteins along with fats and oils, but these don’t have all of the nutrients you would need to stay healthy.
Vitamin C, flavonoids and dietary fibers are some of the nutrients you can’t get through proteins or fats. While it may be possible to supplement these without adding carbs, it would take a LOT more effort than it would be worth. In order to burn off 10 grams of carbs, it only takes 40 calories and that is way too low to risk your health over.
