I'm a bit confused. I assumed that any energy consumed during the day would be subtracted from the energy taken in. So if I consumed 2500 kCal and I burned 1000 kCal, my total energy intake for the day would be 1500 kCal. The bar at the top of my screen does not appear to show that. I see a few arrows on the bar, but ai don't know what they are and my calorie count is only representative of what I've eaten. Am I missing something here?
