I know they calculate calories burnt etc but does it measure the calories burnt just during daily activities? It could be useful as i've always wondered how much I burn while i'm working. I just saw them on the show Bringing Sexy Back and wondered whether it could be something worth asking for for Christmas

About the same level as you'd get with a mobile phone sitting pressed up to your ear, or tucked away in your bag, or back pocket.Tams wrote:I saw the ads too...while intrigued, my main thought was 'ugh, what kind of radiation(other energy) is that device emitting that is strapped to you all day?' Anyone know?

It depends on the device. Some of the battery operated ones, like mobile phones that acces Bluetooth to transmit the data don't need to be synced to any other device such as a computer, and really if the data is accessible directly via the wristband why bother transferring it to a computer? Unless you particularly want to?!!

Worse if you are switching from one device from another...each is calibrated differently.
One device's 100 calories burned is another 70 calories burned.
A good example of this is my exercise bike read out. If I pedal on level four for about 25 to 30 minutes...the read out tells me I have burned off 500 calories. Very satisfy but no where the truth of the matter. Also the body is never consistent neither. After a 90 minute session (1,500 cal) on the exercise bike my daily results before and after weigh ins on the scales can widely vary. Sometimes the result is different because of exercise intensity (ie finishing off harder/faster) but other times the metabolism is just processing faster or slower)...and sometimes it is just me sweating more!
These sort of things should only be used as rough guides and not as gospel...there are just too many variables for them to be anything else.

On a fundamental level it is true but there are so many unknown variables in the process that unless you are being monitored by a team of doctors and scientists you aren't going to be able to cover all the bases.
This simple view of weight loss just doesn't cut it in the real world.
I think of weight loss more in terms of an art form. Sure you develop skills and techniques but the real work is applying them in a creative process using experience and common sense. Just as in art the picture is more than the line on a piece of paper - so too with weight loss.
