The keto diet is a low-carb eating plan that leads to ketosis. To achieve this, the diet needs to be very low in carbohydrates, high in dietary fat, and include a moderate amount of protein.
This diet works by depleting your body of carbs, forcing it to break down fat for energy.
Ketosis is a normal metabolic process that your body uses to keep functioning. When there aren’t enough carbohydrates from food for your cells to use as fuel, your body burns fat instead, producing ketones as part of this process.
It may take a few days or even weeks to feel your best on keto. You might experience some initial symptoms of carbohydrate withdrawal, but once you become fat-adapted, carb cravings usually decrease significantly.
