At the most basic level, Keto is when you change your diet to match a low-carb, high-fat diet. Your body uses pre-existing fat as fuel, not the carbs you eat! Although keto meals allow for some tasty fats, it can sometimes be challenging to follow a low-carb diet, especially if you have eaten carbs before! Keto is a pretty strict diet, but it's one of the main reasons people can lose so much weight by following it. At times, following the keto lifestyle can seem incredibly tough, and you may want to take a break.
