At the first couple of days once you commence following a ketogenic diet (by limiting your internet carbohydrate intake to 20g/day and consuming adequate fat and protein), your own body will be using the glycogen that's stored in your liver and muscles as its primary fuel source. Once the glycogen becomes exhausted, your system will have to change to burning fat as a primary fuel (instead of sugar ), meaning you'll enter a state called nutritional ketosis. Depending on your previous diet plan and how dependent on carbs you were, this may be a massive change for your body, and it'll need a while to get used to it.
