I'm not sure there's any way around this risk. There's no way to tell what your ideal calorie range is except by experimenting.

It doesn't make sense because you're thinking of calories burned as a constant - it's not.
Weight gain/loss/maintenance is a matter of calories in and calories out, but what you eat (and tons of other factors) can affect the "calories out" part of the equation.
One way that too few calories can work against you, is in having less energy. The less energy you have, the less you move - even in little ways you might not notice. Your body may also reserve energy in ways you would never notice.
I was absolutely shocked to discover that I lose more weight on 1800 calories of low-carb than on 1800 calories of high-carb (even when accounting for calories from fiber which can't be digested and for the little bit of extra water weight loss that always results in the first couple weeks of reducing carbs).
I only happened to discover (because I was keeping a health log that included a spot for taking a daily body temperature reading) that my body temperature is actually almost a full degree higher on low-carb. My normal body temperature has been in the 96's for a long time. I only get readings of more than 98.0 when I'm very sick or when I'm eating low-carb. Maintaining body temperature requires energy (calories) and so assuming that the air temperature is lower than body temperature, maintaining a higher body temperature burns more calories than maintaining a lower one.
I'm not at all saying that what's true for me is true for you, but there's no way to determine your best calorie or carb level (or a thousand other things you may want to learn, such as which diet you feel best on mentally and physically) without experimenting. And experimenting always entails the risk of learning that your "old way" was better.
