Measure Body Fat Accurately Using the Buoyometer

What is the Buoyometer?

The Buoyometer is a body-composition device that uses buoyancy-based measurement to estimate body fat and overall composition more accurately than a traditional scale. Two people can weigh the same while having completely different body compositions. The Buoyometer is designed to reveal the difference.

How Does it Work

The device determines body density using underwater weight and buoyancy calculations.

By understanding body density, users can better determine body fat percentage, track physical progress more accurately, and make more informed fitness and dietary decisions

Who it’s for

The Buoyometer is designed for anyone who wants a deeper understanding of their body composition and overall health. Traditional scales only measure total weight, but two people can weigh the same while having completely different levels of body fat, muscle mass, and fitness. A person can become stronger, leaner, and healthier without major changes in scale weight. Likewise, someone’s health can decline while their weight appears unchanged. The Buoyometer helps reveal the difference.

Accessible body composition measurements.

Hydrostatic weighing (see photo above) has been the historical “gold standard” method of determining body composition.
The buoyometer is a simple analog device that accurately and easily measures your hydrostatic weight. No need for a laboratory nor an observer – all you need is a body of water and a few minutes. Take measurements weekly, monthly, yearly – as often as you like. Knowing your body density lets you determine whether you’re gaining muscle, fat, or staying the same.
Hydrometers have been used for centuries to determine solution densities. I like to describe the buoyometer as an “inverse hydrometer” – where the solution (water) is used to determine the density of the body. Because “lean” body mass is heavier than “fat” body mass, knowing your body density easily translates to body composition. The idea of using a “float” to measure body density was originally patented in 1989. I call this patent the “pickle jar patent.”

In efforts to improve on the “pickle jar” patent, above, I brainstormed and experimented with improvements. The end result is the buoyometer [see patent below].
