But you can do a lot of things to suppress hunger. Your body can get used to you eating far too little. You can eat very low carb and be in ketosis. You can have an eating disorder.
If it's a concern, I'd try eating intuitively for a couple days, write down what you eat, then go back and count the calories and see if you can rely on your hunger to make you eat enough.
