Hello, I recently purchased a Spark 3 cardio watch, I noticed that when I go to bed (not wearing the watch), in the morning it always signals around 400 kcal having been consumed. How can I make the watch start from 0 kcal in the morning?

Thank you in advance for any advice!

    If you were alive and breathing, digesting, etc. then you were burning calories and that is what a 24/7 activity tracker is supposed to be tracking. It computes a BMR based on your gender, height, weight, etc. and takes this along with steps and sports activities to come up with calories burned. So between midnight and whenever you woke up you burned 400 calories just being alive. This is exactly what it and all other activity trackers are designed to do. In my experience it is generally pretty accurate (or as accurate as BMR based calculations can be as they are based on averages). If you do not want this then you would need to turn off the activity tracker altogether as it is designed to capture your full daily energy expenditure, not just when you are awake.

    I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
