It takes 6 to 8 weeks to become fat adapted so your body is in the process of learning how to use its new fuel supply So Don’t worry about calories in the beginning 
To help with cravings try one of the following 
A pinch of Salt on your tongue once dissolved chase with a 8 oz. glass of your preferred LC drink.
1 oz keto snack - cheese, nuts, salami, peperoni with a 8 oz. glass of your preferred LC drink
Sugar free Gum and a 8 oz. glass of your preferred LC drink
After trying one wait 15 - 30 minutes if you are still hungry either try again or have small keto meal.
