The ketogenic diet is a low-carb, high fat, moderate protein diet. An individual following a keto diet must eat no more than 50 grams of carbohydrates a day or less than 5% of their daily intake should come from carbs.

Eating a low amount of carbohydrates causes the body to switch from using direct glucose as its primary energy source to using fats instead. The body will start to break down fat cells and convert the resulting fatty acids into ketones.

Ketones enter the bloodstream and are used for energy by the active tissues and organs in the body. This process will continue until carbohydrates are reintroduced into the diet.

The Ketogenic Diet in a Clinic Setting

Originally, the ketogenic diet was used exclusively in clinical settings. It was first used as part of the treatment of epilepsy, as low-carb diets were shown to be effective at reducing the frequency and severity of epileptic seizures.

The keto diet is great for those with diabetes and polycystic ovary syndrome (PCOS) to aid with blood glucose regulation. Studies also show the benefits of the ketogenic diet for those with neurological disorders, obesity, and heart disease.

Nowadays, the ketogenic diet is popular among the general population. Many people go low-carb to improve their overall health or to aid in weight loss.
