Weighing yourself used to be a simple process: you stepped on the scales, winced at the dial, then lied about the figure to your significant other.
These days, there's more to it. A new breed of smart scales can now track all manner of stats, from BMI and body fat to heart rate, plot your progress on your smartphone, and even link with your fitness band for true 360-degree health monitoring.
In fact, about the only thing these scales won't do is lie to your family for you; you'll still have to do that bit yourself.
We've put the best models through their paces to see which is best entrusted with your precious BMI info.

A lot has been written about the value of the data collected by fitness and health tech - not least by Stuff ourselves - but whatever the insurance companies have planned for our future premiums, there’s no escaping the benefit of cold, hard statistics right now.
The good news is that data remained consistent and trustworthy throughout our testing – although natural fluctuations always occur when measuring body fat levels, as time of day, amount of water drunk and even how clean your feet are will all have an impact.
But which to buy? If money is tight and you’re only interested in weight then the Wahoo Balance will do just fine, but given there are so many more factors to fitness than pounds and ounces, it's worth spending more. The Tanita RD-901 is based on a professional machine and piles on the stats - useful, but with a less-than-perfect app, it could be daunting to the uninitiated. Salter's Curve Smart Analyser Pro keeps things simple, and is all the better for it. The price it right, too.
That leaves Withings and the Fitbit. All combine a slick app with stylish looks and accurate data; all are intuitive to use and provide motivation far beyond the statistics.
With heart rate and air quality monitoring also thrown in, Withings just about wins this race, but bear in mind that neither are cheap, especially if you go the whole way (and you should) and invest in a fitness monitor too.
Still, if there's one thing worth spending some money on it's surely your health.
