The keto diet (also known as “the ketogenic diet”) is a type of diet where you limit your carb consumption to a very low daily amount in order to get into a metabolic state called “ketosis”.
When you’re in ketosis, your liver uses fat to produce ketones, which are then used for energy by your brain, muscles and all other organs. Fat becomes the primary fuel source of your body, instead of glucose, and your fat stores become easier to access.
Typically, carbs are limited to under 20 or 25 g daily, although there might be some slight variations to that. To make the diet sustainable, it is important to consume an adequate amount of protein (to maintain your muscles and organs) and sufficient fat (to have enough energy to function).
There are different approaches to keto, based on how strict you want to be, and on your personal preferences and activity level.
For example, for people who are fairly active, their carb limit (i.e. the amount of carbs they can consume in a day and still stay in ketosis) might be slightly higher - 50 g net carbs or so. Protein can also be higher or lower, based on your goals and preferences. Fats are used to complete your caloric needs - they give your body enough fuel to sustain yourself, and also keep you full.
