Don't worry about calories the first couple of weeks, eat lots of fat until adapted. Have you researched the launch pad? It has tons of helpful information for situations like yours.

Are you getting enough sodium? 3000-5000 mg is recommended especially in the beginning (and maybe always) because of the normal diuretic effect of low carb.

As much as I didn't want to increase my sodium intake, I found it extremely necessary for balance of electrolytes and not getting symptoms of "keto flu". I have also learned that my feelings of hunger are often a need for increased sodium. This worked/s for me as I remain a calorie counter on keto.

I echo what @SuperCarLori said - eat lots of fat. That's what keeps you satiated.

I agree with other posts about making sure you have enough sodium to help prevent "keto flu." I add salt to my drinking water and actually like the taste quite a bit. And, I have gone through the keto-adaptation phase three times in the past six months (i.e. I went back to eating carbs and had to start again.) I've noticed that my appetite was pretty much the same when I first started eating low carb/high fat. After I lost the water weight, which was about 5 lbs, my body just stayed put -not losing or gaining- as I continued eating the same way. However, after about a week to 10 days, I found that my appetite lessened. I no longer have the crazy hunger pangs in the middle of the afternoon. No more desire to snack between meals, and I can eat fairly small low carb meals and feel full. Just give it time and think of this as part of the transition phase.

The lack of hunger takes a while. I'm always starving for the first week so just eat what you need as long as it's low carb - rich food like cheese and bacon can be good as they really feel like indulging.

I agree with what the others have said here, add more fats and protein until you don't feel hungry anymore. For the first couple weeks I only tracked carbs, not calories. I ate until I was full. I snacked on almonds, DARK chocolate (90% or more), beef jerky. I ate loads of veggies, bunless burgers, cauliflower mash, twice baked cauliflower, meatballs, chicken wings, fathead pizza, salads, you name it. Take the first little while to re-learn how to eat and what to eat, otherwise you might get overwhelmed and start binging, or worse, giving up. One step at a time!

Important to add though - I didn't add anything with artificial sweeteners until later on, maybe a month or so later until my body had adapted, otherwise they'd send me into a hunger spin constantly craving food! I had to get all the sugar out of my body and then slowly re-introduce those sweeteners later to see how they'd impact my hunger/cravings.
