The goal of the diet is to force your body into a metabolic state of ketosis, a process by which the liver naturally begins to burn fat instead of carbohydrates. With your body in this state, you will burn more fat and therefore lose weight. This diet is low-carb-high-fat, with the increased fat intake contributing to that kickstart of fat burning ketones. Ketones are produced from the breakdown of fat in the liver.
The Keto diet came out of the Mayo Clinic in the 1920s as a way to manage seizures in patients with epilepsy. Although it became less prevalent as a treatment as anti-seizure medicine gained in popularity, we now see it once again in the health and medical world as a popular diet trend. In this method and meal plan, by changing the source of your body’s fuel (the food it consumes) you are changing what is being burned. Eating more fat and fewer carbohydrates (and sugar) means that fat is burned instead.
Consuming foods that are high in fat is super important here, as they provide the fuel that the body needs in order to run. Foods in this diet include healthy fats, like olive and avocado oil, proteins such as salmon, beef, eggs, and chicken; leafy greens and non-starchy vegetables, like spinach, kale, broccoli, and cucumber.
