|don't starve beginner guide The end goal of a properly maintained keto diet is to force your body into this metabolic state. We don’t do this through starvation of calories but starvation of carbohydrates.To start a keto diet, you will want to plan ahead. That means having a viable diet plan ready and waiting. What you eat depends on how fast you want to get into a ketogenic state (ketosis). The more restrictive you are on your carbohydrates (less than 25g net carbs per day), the faster you will enter ketosis.
