It’s true… body fat scalesAREone of the mostconvenientways to measure your body fat percentage.

But just howreliableand accurate are they?

Body fat scales have some tremendous advantages over other types of body composition tests. Here are some of the most important…

Availability
How many places do you know that provide underwater weighing or DEXA (these are generally considered the most accurate ways to measure body fat)?

Once you have a set of scales they are right there whenever you need them. And what about…

Expense
Anything with a name like Dual-Energy X-ray Absorptiometry (DEXA)hasto be expensive right? It is! Even good quality body fat calipers aremoreexpensive than most scales.

You can buy a good set of body fat scales for under $100 and you can use them again and again.

Convenience
Would you rather have a body fat test in theprivacyandcomfortof your own home or in a lab? Body fat scales are there right when you need them, no appointments to make and no travelling to do.

And probably the most important benefit of all…

Self Testing
There areonly a few waysyou can test your own body composition. Using scales is one of them. Even most calipers require someone else to take the measurements for you.

How Body Fat Scales Work And Why It’s Important

Body fat scales use a technique called Bioelectrical Impedance Analysis… or BIA for short. Very simply…

A small andcompletely harmlesselectrical current is passed through your body. The electrical current passesmore quicklythrough fat free tissue like muscle than it does through fat or bone tissue. So…

The amount ofresistanceto the electrical current relates to how much fat-free mass a person has and their body density. Here’s the first challenge…

Like all body fat tests, body fat scales don’t actually measure your body fat percentage. They determine yourbodydensity.The examiner (or the scales) then uses a formula to calculate body fat percentage based on body density. Here’s the key…

These formulas justpredictyour body fat. Unfortunately there is no one formula that accurately predicts body fat for the whole population. Differences in age, gender, ethnicity, body size, and fitness level all have asignificantaffect on the results.

Most scales can account for some of the basic differences such as age and gender, but take the actual body fat percentage they give you with a pinch of salt. What does this all mean for you?

Well, whether body fat scales measure your“true”body fat percentage or notdoesn’tmatter!As long as they can accuratelymonitor changesin your body composition over time, that’s all you need.

Your body position, the amount of water in your body, your food intake, skin temperature and recent physical activity can all adversely affect the results of body fat scales. So…

To achieve accurate, consistent results, you muststandardisethe way you perform each test. That simply means making each test with your scales as similar as possible. The great thing about body fat scales is…

Standardising each test iseasyto do. Check out theTop 10 Tipsat the bottom of this page to get the most from your body fat scales.

Are body fat scales any better than plain old weighing scales?

Absolutely!

One of the biggest mistakes people on a weight management program make is gauging their progress by weight alone. For all the reasons you should calculate body fat see thebody fat percentage article.

The10 Top TipsWhen Buying And Using Body Fat Scales

  1. Use them tomeasure your progress only. Don’t compare your body fat percentage to tables or to your friends score. It is probably inaccurate no matter what the manufacturers say.
  2. Choose body fat scales that have theright profile for you. If your children are going to use them make sure they can be calibrated for children. If you’re an athlete (+10 hrs of strenuous exercise a week) same thing applies. This is important. It makes abigdifference.
  3. Measure out some water one hour before you test yourself. Make sure you alwaysdrink the same amount of waterone hour before you test yourself.
  4. Measure yourself at thesame timeof day for each test.
  5. Your skin temperature affects the electrical current used by the scales. It’s difficult but try to test yourself in asimilar room temperatureeach time.
  6. Don’t test yourselfafterexercising. When you exercise you sweat and when you sweat you lose water. This affects your hydration levels and hence… the results.
  7. Thoroughly clean the foot pads, preferably with alcohol and then dry them off each time you test.
  8. Buy the most expensive body fat scales you can afford. Accuracy will almost certainlyincreasewith price.
  9. If ever you get the chance, have your body composition measured by a professional using skin fold calipers. It will give you a frame of refernece as to how accurate your scales are.
  10. Read the page onbody fat calipersfor an alternative you could consider.

How To Lose Body Fat… Not Just Body Weight

Many diet plans may help you lose weight in the immediate term, but the results are often short-lived. Aside from these diets being too restrictive and inflexible, they result in more fluid loss than fat loss.

The most effective fat loss programs increase your resting metabolismeven when you aren’t exercising.The result is that you burn more fat and more calories during your everyday activities… even while your watching the tube!

When you have your metabolism working for you, rather than against you, permanent fat loss becomes so much easier and more enjoyable.
