Researchers weigh in on the Body fat versus BMI debate

 Anyone trying to lose weight, get fit, and stay healthy might get a wee-bit confused by all the back and forth and why which one matters most:  BMI or Body Fat.  For years, researchers have debated these two indicators of health.  Finally, it seems they’ve agreed on one over the other, and for valid reason.

Body Fat Percentage versus Body Mass Index (BMI), is a more accurate indicator of the body’s health condition, according to research by Sciencedaily 

 (www.sciencedaily.com/releases/2013/08/130822141948.htm).  The calculation of a person’s body fat can be measured through several methods.  Waist to hip is a quick way to measure body fat.  Body fat weight scales will produce an overall view of your weight, body fat and BMI.  Other methods may include underwater and handheld calibration equipment.  

The body’s BMI does not necessarily reflect a true picture of the entire body.  Essentially, someone could weigh more producing a higher BMI but have greater muscle mass and lower body fat.  Another person could have what appears to be a healthy BMI (19-24) but have a higher amount of body fat.

Heart disease and diabetes rank at the top of the list as two diseases typically related to higher body fat percentages.   Smoking, high cholesterol, high blood pressure, inactivity and excessive weight around the abdomen are red flags, as well.

Where we carry our fat matters more than what we may realize.  Our waistline is a quick indicator of our potential for health risks: The higher the number around the waist line the greater the concern.  Start by measuring your waist at the belly button.  A woman with a measurement above 35” and a man with a measurement above 40” are putting themself at risk for disease.

Fatty tissue produces pro-inflammatory chemicals and hormones.  Each one assists in regulating metabolism, which in turn impacts the immune system.  Some cancers, hardening of the arteries and inflammation associated with higher body fat percentages.  Through the environment and consumption, toxins deposit into the fat cells working against the metabolisms efficiency.   Reducing body fat through healthy nutrition and exercise helps to lower body fat, as well.  Something as simple as drinking at least half your body weight in ounces of filtered water a day will help release toxins while keeping your body hydrated.  (Example: 160 lbs = 80 ounces of water).  Each help to reduce body fat over time.

Most of us would assume that higher body fat percentages equal higher numbers on the scale; however, that is not necessarily the case.  Two individuals could weigh exactly the same while one has a higher body fat percentage and the other a higher muscle mass.  Healthy muscle mass is preferred over excessive body fat for obviously good reasons: Muscle mass helps protect the body, while supplying a healthy resource for energy storage.  

Building strong muscles requires discipline including eating healthy nutrition and consistent fitness/exercise.  Superficial muscle mass, produced through the consumption of supplements or steroids, will not produce overall health benefits.  Choose to build your muscles naturally and your body will pay it forward through good health and wellness.
