I wear a Fitbit that tracks my heart rate. I’ve been really stressed recently which is causing my heart rate to spike at times. When this happens, Fitbit tells me that I’m in the “exercise zone” and that I burned a ton of calories. I’m assuming this is because my heart rate falls into the exercise “fat burn” zone, but does my body actually burn any more fat than usual if I’m just sitting at my desk and anxious? Seems way too good to be true…

No, the calorie calculations are assuming that your heart rate is rising due to movement of your muscles.
Emotional stress is just strain on your organs.
