Originally designed in the 1920s by researchers at Johns Hopkins, the ketogenic diet is a low-carb meal plan that was made for epileptic patients which showed that fasting, or avoiding food for a certain amount of time, helped reduce seizure occurrences. It also helped reduce fat, blood sugar, cholesterol, and hunger levels, since the fasting required avoidance of all foods, even carbohydrates.
Since long-term fasting isn’t a healthy option, they developed the keto diet to mimic the benefits of fasting. In simpler terms, this diet tricks your body into thinking that it’s fasting since you’re getting rid of all of the sugars found in carbohydrate foods. Today, it has several names aside from the ketogenic diet, such as a no-carb diet or a very low-carb keto diet.
What does keto mean, though? Using a keto diet sends your body into a state of ketosis, where your body gains its energy from ketones in your blood instead of using the sugar in your blood to create energy. The glycolytic state does this, but the ketosis state is what helps your body when you following a ketogenic diet.
