Has anyone used it with success? I'm interested in it because i eat so litte, but still I'm satisfied. That's why I'd like to know how much kcals i really burn. kcals calculators on the internet estimates that i need around 2800 kcal, but i think that's BS.
I wouldn't waste your cash unless you are desperately trying to lose/gain weight.
Remember that protein is very satiating so if you eat a lot you might feel more full then you actually are and you could be slightly undereating. Unless your losing weight or trying to gain I wouldn't worry about it too much though.
I have the Exerspy (By the same company - Body Media... http://rippedusa.dotfit.com/exerspy-pid-1619.html). I love it. It tracks your calorie burn, activity level, sleep patterns and number of steps. I use it to monitor my non-workout activity...to make sure I'm staying active throughout the day. And based on my very unscientific observation in my own experience it seems pretty accurate.
That thing is probably not very accurate.
How do you measure calories burned after all?
I'm not sure it can be done accurately enough to be useful. And I don't think this machine is worth the bother.
As Gary Taubes argues, eating by balancing calories is impossible. You would have to balance input/output by less than 1 percentage per day to avoid getting fat. If you overeat by one percentage a day for ten or twenty years, you will get fat.
Obviously, this is not how the system works. Our body does not count calories. Alas, counting calories does not help you.
Regulation of body mass is a lot more complex than the input/output theory suggests. Luckily, the solution is simple:
Eat real (paleo) foods and trust your hunger.
What you are experiencing is probably just a good example of how inaccurate calorie counting is as a guide for eating.
So, yes, that online calculator is BS. And so is that device. Don't buy :-)
