When you don’t eat carbs, your body — mostly your liver — can produce glucose out of protein and byproducts of fat metabolism. Therefore, because of ketosis and gluconeogenesis, you don’t need dietary carbs — at least not for fueling your brain.
Is it OK to eat no carbs on keto?
A no-carb diet resembles a ketogenic diet, which limits your carb intake to fewer than 30 grams per day and encourages you to get 70% or more of your daily calories from fat ( 2 ). Depending on what you choose to eat, a no-carb diet can be more restrictive than keto.
What happens if you don’t eat enough carbs on keto?

How many carbs will break ketosis?
When the body receives less than 50 grams of carbohydrates a day, it will run out of its preferred fuel source — glucose — and this will happen 3 to 4 days after the beginning of the diet. At this point, the body will start to break down protein and fat to get energy. This metabolic process is called ketosis.
Does alcohol affect ketosis?

Specifically, it will slow down your rate of ketosis. “The liver can make ketones out of alcohol,” Atkins nutritionist Colette Heimowitz told Elite Daily.
