You are still in early days, yet, so don’t deliberately restrict your calories. You want to give your body all the energy it needs; once it is assured that times are good, it will start mobilizing your fat store. While people have been known to metabolize stored fat even while eating a high number of calories, most people on a well-formed ketogenic diet eating fat to satiety unconsciously end up restricting themselves to around 1500 calories a day, simply by listening to their hunger signals. So for right now, make sure your meals are as fatty as possible while keeping protein moderate and carbohydrate as low as possible. When your satiety signals start to kick in, you will find yourself automatically cutting back on how much you eat, and any calorie restriction you end up making will happen without your having to think about it.
The beauty of this way of eating is that as you continue eating fat to satiety, the quantity of food in your diet will increase automatically as the store of fat in your body melts away.
I should note that for me, a sugar/carb addict, satiety is a weird experience. The first time I experienced it, I was planning to eat my usual pre-keto quantity of food, but halfway through the meal (it was broiled salmon), I had to wrap up the food on my plate and save it for a later meal. My stomach was nowhere near full, but I was not interested in eating another bite. Very strange, for this just-one-more-wafer-thin-mint kind of guy!
