Yesterday I went to my Spark start page and found the "Account/E-mail Preferences" and went to the Account tab. I reset the "How My Daily Calorie Range is Determined" to unlink my fitness tracker from my nutrition tracker. I used to really like being able to track fairly accurately what I could eat for the day. Especially when I have very active days, like 16 mile runs, my body needs more food than on a day I walk or even run fewer miles. So I liked having them linked UNTIL:
I started relying on my Garmin Vivosmart HR which automatically links to my Spark fitness tracker. It may give me accurate heart rate, it may report my sleep hours and my steps just fine, the time I spend in walking or running mode is right on, the distance I achieve in exercise activities is a good estimate, but the calories? Pure fiction. On long runs the Garmin could show me burning 750 calories half that would be far more accurate I am sure.
Why the discrepancy? I asked SparkCoach. One answer is that the Garmin is counting the basal calorie rate and the activity calories, so when we add that figure to SparkPeople we are double counting the basal calories. SparkCoach went on to say that steps around the house probably don't burn as many calories as a purposeful walk, although the device doesn't know the difference.
Bottom line, I know I can't eat all the calories my new Garmin tracks without gaining weight. So I won't!!
My device will still report my activity to my fitness tracker and I'll get my SparkPoints and have my history of steps and activity automatically filled in. I like that!
When I'm trying to lose weight, my rule of thumb is a little over 1200 calories (BMR) plus half of the conservatively estimated exercise (running, power walking, cycling, etc) calories; nothing extra for just walking around or things like slow dancing or bowling or housework. As I switch to maintenance I'm going to have to experiment with eating a few more of my exercise calories. Today I -- woohoo! -- weighed in at 122.8, my lowest adult weight ever!!
