I've been wearing my BodyMedia Lync for the last week, now that it's integrated with Spark. I mentioned my doubts about its calorie-burn-tracking accuracy already, but wanted to make a quick in-progress update.
I wore the armband all week, all the time (except bathing and during my yoga class today). Two days I wore it on my calf at work, which I know is less accurate, but I don't want it on display in my workplace - too much to explain to too many people who wouldn't understand. The daily calorie burn is astounding... and I know that Spark only adds the calories tracked during "moderate and intense exercise", but it's still upwards of 800 calories a day that, tracked using Spark's own fitness trackers, I'd never have burned. Even if it's double-counting the sedentary BMR calories AND the exercise calories during that "moderate and intense exercise", that's like 70 calories an hour, not THAT many extra calories. Not 800 a day. Because seriously:
Today? 952 calorie deficit.
Yesterday? 821 calories.
The previous days? 409, 346, 459 calorie deficits... these are days I pigged out. By all means, I should not be LOSING weight on days I consume 2100-2200+ calories and don't do any real exercise. Certainly.
However, as I'm so fond of repeating, my rear end is keeping track even when I'm not, and even when Spark and BodyMedia are providing conflicting information. The proof is always in the pudding, so I will be interested to see what the scale says in the coming days. I have my suspicions that it will favour Spark's calorie counting over BM.
REYNINGSUNSHINE pointed out in her comment to my previous BM-vs-SP rant that she wasn't losing 2 pounds a week when she had a thousand-calorie daily deficit, but when she upped her calories to 1500/day, she started losing. Well... yes. But I'm nowhere near 1200 calories a day, and no way can I use that "starvation mode" alibi for poor scale performance, as much as I wish I could. Oh man... As if I'd ever have the problem of eating too little, ha ha!
And I don't drive, although that's a good tip - I wonder if it's an issue on the Train (if I'm standing still, not moving my arms around)? Yesterday I took the Train home, and it registered 22 minutes of activity between 5 and 6pm, which is my commuting time. That's probably about right for my walk from my office to the station plus my walk to transfer and then walk to meet Max. Wednesday was a bit more, Tuesday a bit less. I'll keep an eye on it, though. It does rely on an accelerometer, it might get confused by the Train movement, if it's really sensitive.
In other news, I'm still tracking and have been pegging over 100 grams of protein per day all week. Exercise was good: three run-walks, two yogas, and a couple quick bouts of strength work. Calorie intake was all over the board, and I haven't been avoiding sweets like I said I would, but with my activity level picking up, I'm happier focusing on balance rather than hard rules. Perhaps I'm just being soft. But I'm happy, and that's what matters, right?
I'll hop on the scale tomorrow morning and see if I'm still happy then.
Or just soft! Ha ha!
