As opposed to a lot of other diets on the market, the Keto diet relies on high-fat consumption, with very few carbs. The majority (75%) of your calorie intake on Keto comes from fat. Whereas only 5% of your daily calories come from carbs. This tricks our bodies into changing its fuel source to fat from carbs. This, in turn, results in the production of a fuel source called ketones. Once this change occurs, you are in ketosis.
