Omron HBF-306C Fat Loss Monitor Review

Daniel Brady | November 18, 2012 in Equipment

The Omron HBF-306C Fat Loss Monitor is great value for somebody who wants to measure their body fat changes regularly, but don’t have access to a superior machine such as the Tanita BC-418. With a price around the $30 mark, it’s a small investment considering the benefits you’ll receive. Compare that price with the $5000+ price tag of the Tanita BC-418 and the difference is vast.

While the more expensive Tanita machine returns a more accurate body fat figure, the Omron HBF-306C is still valuable for showing any changes to your body composition. If you want to know very accurately your body fat figure you’ll need a more expensive machine, but if you just want to know by how much you’ve improved each month (or 2 weeks), the Omron machine will be sufficient for a great price.


  • You’ll have a hard time finding a better one for this price, except for another Omron monitor.
  • Easy to use.
  • Reasonable accuracy. For me it reported 15.6% versus 13.9% from a far more expensive machine.


  • The electricity only passes between your hands, leaving the rest of the body to be estimated, leading to lower accuracy. Leg-to-Leg machines are superior.[1]
  • The level of accuracy can vary between individuals, body types and hydration levels.[2]
  • If you leave your arms down rather than up and out front, the reading can be very inaccurate.

It’s easy to use, portable and cheap. So if I’m ever without access to a superior machine, this would be one of my first choices. It’s easier than fat calipers and avoids the user error of calipers.

Daniel has a strong interest in evidence supported fitness training, preparation and supplementation. His goal is to provide clear information that simply works. He's currently 16 kg of muscle above his starting weight (7kg in the past 12 months), and targeting a continued growth rate of 5kg+ per year.
