I bought my Vitafit fromAmazonfor around $20, and I honestly wasnt expecting much.
That was until I tested it during my recent Vitafit Bathroom Scale review.
It boasts Class III Non Automatic Weighting Instrument (NAWI) accuracy and MDD Class II-a medical gear classification.
Basically, its some of the best body composition tech on the market.
So just how well does our $20 health hero stack up to this $8,500 behemoth?
I ran a series of controlled tests on the Vitafit and the Tanita to find out.
The pair share 11 total measurements: heres how they stacked up.
The Vitafit came within 0.15 kg of the Tanita for body weight in both measurements.
The latter lower weight reflects the energy Id expended walking to and from my gym between the second tests.
I couldnt believe the Vitafit was so close to the Tanita, a fantastic start.
Vitafit seems to be lowballing this one, reading between 1.3-1.4% lower than the Tanita.
Thats quite a significant discrepancy in a reading of around 26-27%.
Vitafit seems to be overegging this one, measuring 1.4-1.5kg more than the Tanita.
However, that checks out when you consider its underestimating body fat.
However, according to my calculations, its overestimating muscle mass by 1.3-1.4kg.
Again, this fully checks out with the discrepancy in body fat above.
A healthy amount is important to protect your organs, but too much can lead to serious health issues.
Tanita clocked me at a 10, while the Vitafit scored me a whopping 18.
Considering that the Vitafit underestimated overall body fat, this is a further surprising result.
It wont surprise you to learn Im going with Tanita on this one.
Body water is the total amount of fluid in your body and a key marker of dehydration.
This is another one Im taking with a pinch of salt (or should I say electrolytes?).
Its essentially your body mass divided by the square of your body height, expressed as a number.
There are some limitations because it only measures overall weight rather than body composition.
For the Vitafit, however, its another string to the bow, scoring within 0.1 of the Tanita.
Your metabolic age is a comparison of your BMR versus the average for your age group.
Ideally, you want a score that reflects your actual age or is lower than your actual age.
The Vitafita and Tanita were worlds apart here, but I reckon theres a good explanation.
As noted, the BMR scores given by each were very different, likely reflecting different methodologies.
Im less concerned about BMR and metabolic age because those appear to be calculations rather than measurements.
