My gut has developed into a shameful size and I'm officially disgusted with myself. For the first time in my life, if I relax my belly whilst standing, I can no longer see my todger. Shocked

So, in the light of this, I'm back in training and this time interested in monitoring my weight loss as it (hopefully) happens.

I looked on Ebay for a set of digital scales and notice (apart from how bloody expensive they are) that many now come with 'BMI' and muscle mass/hydration measurement capability.

eg: http://www.ebay.co.uk/itm/Salter-Bodywise-9117-Stainless-Steel-Analyser-Digital-Bathroom-Scales-9117-ss3r-/221064341904?pt=UK_Bathroom_Mats_Rugs&hash=item3378762990

I'm assuming this is purely calculated based on you putting in your height and the machine cross-refs this with your weight rather than the machine actually genuinely measuring anything other than weight?

Has anyone found these machines useful / worth the money? Anyone got their tuppence worth on this subject?

For the BMI - yes that is all it does, a simple calulation.

However it also does bodyfat/hydration by passing a current from one foot to the other and measuring the resistance. They are pretty inaccurate though, the cheap ones even more so.

+1

Our Weight Watchers set at home are about 2% out on my % body fat when compared to body fat according to calipers & BodPod measurement. I was 11% on that, 9% on the scales.

That said, they are useful for keep track of overall trend, so at the moment I am showing as 11.5% body fat on the scales and would therefore be around 13.5% if measured more accurately.

If thats the case, then surely the scales are well worth the money (Nothing like false information to give you that sence of satisfaction) Wink

The body fat relies on electrical impedance/conduction up one leg and down the other... So not a full body measure, just your legs.

On the bright side, that misses out the gut, so your reading would be better!

Calipers/bod-pod etc style measurements are more accurate.

BMI is not that relevant to athletes either...

And how accurate are bathroom scales? Unless you pay out for decent healthcare set, most bathroom scales are a rough indictaor rather than scientifically accurate.

i got a set by homedics from argos around 6 years ago and think they are very useful for keeping track of overall trends in wheight ,bodyfat,muscle and hydration levels.How accurate they are i can t say but if they are a few percent out either way they will be consistent. if mine stopped working tomorrow i would want a new set ASAP. It is not a precise science anyway and if you were measured by three different people with calipers you would have three different results imho.

And just remember! Most doctor's surgery scales read about 0.5 stone high!

Last time i had one of the body fat % tests i had to hold onto a pair of handles as well as standing on the unit. It was at the Porsche testing lab.. I'd really like to get an accurate pair for the house!

You can get full body testers....but, again, there is some degree of inaccuracy....still good for measuring trends

Hello old thread of mine!

And yes - the old bathroom scales I did buy and are still performing their fat-function all these years later Very Happy

I do love these spammers - this resurrection of old threads is a bit like Facebook, where it shows pictures from your past...
