I love it. You can prove anything if you do the right tests and use the right statistics. Which foods did they test over which time? How did they choose them? Do you think anybody uses a Fitbit to calculate how many calories they've eaten or burned?This is all a bit too techy for me. I have no idea about the accuracy of the pulse measurements on sports bands. However, last year a Swedish sudy found major errors in calculations by activity watches/bands. With an error of between 20 and 50 percent when it came to energy consumption. Dr Mikael Mattsson at The Swedish School of Sport and Health Sciences saw possible negative consequences....
"For example, if you try to lose weight and trust too much on these numbers, you might eat 50 percent more than you should because the bracelet says you've made 50 percent more energy than you actually done"
What you can see is an average of about 2000 calories burned on a rainy day, when you sit in and watch TV and play on your PC all day after a lie-in. That's plausible and ties up with what I'd expect. when I go out for a three hour ride on my road bike, it tells me that I burned about 4000 calories during the day. That also sounds about right to me. All the other daily results seem to me to be plausible. It doesn't matter to me if it uses the wrong algorithm to calculate those values.
Nearly everything is calculated by differences from your resting heart rate. that might be right or wrong. what you can see is whether you had an active day or not, but you know that anyway. what's more interesting is how your heartbeat change during the day and during the various activities. you can see changes in recovery rates, resting rates, etc, which are indicators of your fitness.
These things are only gimmicks, but interesting nevertheless. As I said before, they're a lot of fun and the natural result of seeing results, right or wrong, is that you want to improve them. I play computer games, they're completely fictitious and there's lots of results and values in them. It's still fun to play them and to try and improve those values and scores.
