When you first start following a ketogenic diet, we recommend tracking macronutrients and calories just to get the hang of it and to make sure that you’re getting the right amount of each. However, soon after adapting, you should simply be able to eat until you are full while monitoring your carbohydrate intake. Don’t let those sneaky carbohydrates creep up too high. In fact, people who are keto-adapted often reduce their calories unintentionally simply because they feel full faster. If possible, eat to satiety once you get the hang of it; your keto-adapted appetite should ensure that you consume enough calories without overeating. Those using the diet for therapeutic application should incorporate some level of calorie control/restriction in order to receive the best results from the diet.
