Hydrostatic Testing (Underwater Weighing) has become universally regarded by industry experts as the “Gold Standard” in body fat testing.

Gold Standard Testing hydrostatic method uses a two component model which separates the body in 2 areas:

1. Bone, muscle, and organs along with connective tissue collectively known as lean mass sinks (More Dense than Water).

2. Body Fat-floats (Less Dense than Water).

By obtaining your dry weight and water weight (based on buoyancy) our specialized computer program can scientifically calculate your body fat as a percentage of your total weight. The ordinary land scale cannot tell you if weight loss is muscle or fat, while testing with Gold Standard Testing will tell you exactly what took place with your body during your weight loss regiment.

What You’ll Discover:

  • Your fat & fat free body mass
  • How much fat you need to lose to reach your goals
  • Calories you burn each day without exercising
  • Calories you burn from different exercises
  • Where you compare on a scale of age & gender
  • Your history if you’ve tested with us before.


Your resting metabolic rate is the the amount of calories your body burns while at rest.

This number is very important to know. Why? Well you have to take in enough calories to function normally without the right amount of caloric intake your body goes into survival mode(starvation).

While in this mode your body slows down the metabolism and goes for the next best source for energy and that would be muscle.

Sensing that you are under eating your body then goes into fat storage mode. So anything you eat will promptly be stored as fat.

The key to fat loss is to maintain your RMR and keep the metabolism high. This will preserve the muscle and allow your body to use carbohydrates and fat as it’s source of energy. Obviously the quality of calories you consume plays a major role in overall health.

Certain factors such as age, gender, and genetics that help determine our metabolism; however, there is hope because we can change or increase our activity level and thus our lean mass. Furthermore, muscle is metabolically active and the more you have the higher your metabolism. Alternatively, extreme diets and overly excessive exercise can tear down your lean mass and lower your metabolism.
