UA Healthbox

So I got the UA healthbox today and I used the heart rate band for the last 64 minutes of my workout and stretching exercises (cardio day). It said I burnt just over 1000 calories. I had a good pace and a good sweat on the whole time almost.

I’m wondering how accurate the heart rate tracker and wristband are for actually assessing how many calories have actually been burned off. If it’s burned off what it says, then I’m at a huge calorie deficit and will need to up my calorie intake to avoid my body panicking and lowering my metabolism and start saving the fat.
