Mystery of all mysteries... I just ran a report for the last week of my recorded data from my Link. Calculating my calorie deficits for the last week, I should have lost 3.53 pounds over the last 7 days, and you know, my measured loss was 3.6 pounds. I love it when my body does what I tell it to! And I particularly love it when my gadgets are accurate!

(This has not been a paid presentation for the Bodymedia Fit Link... I promise!)

I have that arm band too, not sure if mines as accurate lol. I always think the amount of cals burned is too high for the exercise I did

Does your loss match your measured deficit? Could be a few issues. Your metabolism might not be exactly as expected, or you could be over/underestimating calorie consumption. It only claims to be 90% accurate, so there is some wiggle in there. For me (5'8" with a very ox-like build - I was told by a prominent weight loss doctor in my area that I had the biggest wrists he'd ever seen on a woman... I guess that's what coming from good farm stock'll get ya!), at my current weight, just moderate walking (brisk pace, but not particularly fast) burns me between 8 and 10 cal/min, so generally between 500-600 cal/hour, and my loss (at least pre-op and as well this last week) is almost always dead on. If it's not, I can usually identify the reason, usually Water retention.
