WHAT IS BODY FAT IMMERSION TESTING?

If you want to calculate your body fat percentage, Body Fat Immersion Testing (Underwater Weighing or Hydrostatic Testing) is universally regarded by industry experts as the "Gold Standard" for body composition testing. It’s the method by which all other methods measure their "error rates".

Other methods can sometimes overstate BF% ... AND sometimes understate it. You can never be sure in which direction it will be off and by how much. Not very helpful! In fact, this misinformation can be extremely frustrating and, in fact, counter productive to helping you achieve your fitness goals.

BFIT's Body Fat Immersion Testing uses the most advanced three-component model and separates the body's composition into three areas:

  1. Lean Mass - Bones, muscle, organs and connective tissue which all sink in water (are more dense than water)
  2. Fat Mass - Fat mass is less dense than water so it floats
  3. Water Weight – Your water weight can range from 45% to 65% (even as high as 70% in some individuals!) That’s a wide range. And it varies not just from person-to-person but also from day-to-day for the same person. Your water weight even fluctuates greatly throughout the day (as many people are well aware). Your water weight is neutral in the tank on the wet scale so we effectively take that "noise" (45-70% of your dry weight) out of the equation. This explains (in part) the high rate of accuracy of BFIT body composition testing.

By obtaining your dry weight on a traditional scale and then your wet weight, using our unique underwater scale, our specialized computer program scientifically calculates your body fat as a percentage of your total weight. A traditional dry scale cannot tell you if weight loss is muscle or fat.

Testing with BFIT will tell you precisely what took place with your body during your weight loss (or strength-building) regimen.

That said, other than a postmortem dissection analysis (and what good will that do you?) there is no 100% accurate method for measuring body composition.

There are a number of factors that could slightly skew the BF% reading you get from us (e.g., titanium implants for bone and/or joint replacements or in your skull, extraordinary lung capacity, silicone and/or saline implants, to name a few of the biggest ones).

However, those are all static variables that will not change (under most circumstances).

When you return for your retest and we show that you gained two pounds of lean mass, you can rest assured that that is two pounds of muscle you added…not skeletal structure, not a third kidney and not water weight which we measure separately from lean mass.

If you have fat loss goals (or strength-gain goals!), you need to be dialed in.

BFIT Truck can help you know precisely how much to eat to maximize fat loss while preserving muscle to help you reach your fat loss goals in a way that is Safe & Healthy but is also Achievable and (most important!) Sustainable.

RESTING METABOLIC RATE

Your resting metabolic rate, or RMR, is 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 its metabolism and goes to the next best source for energy: muscle.

Sensing that you are under-eating, your body goes into fat storage mode. Anything you eat will promptly be stored as fat.

The key to fat loss is to maintain your RMR and keep metabolism high. This will preserve muscle and allow your body to use carbohydrates and fat as its primary 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 help determine our metabolism. There is hope though, because we can increase our activity level and thus increase our lean mass.

Furthermore, muscle is metabolically active and the more muscle you have, the higher your metabolism. Extreme diets and excessive exercise, however, can eat away at your lean mass and lower your metabolism.
