Nille sa for siden:
Jeg mener DAMA, hun som av og til får oss til å juble av glede - men av og til gråte av fortvilelse. Har hun rett ?? Er hun ufeilbarlig ?? Skal vi la henne styre oss ??
Jeg har allerede truet med å sende (((((((rustevibber)))))))))) til henne, men lot være fordi hun er så innmari dyyyyyyr. Denne dama selger seg ikke billig nei ! Men betyr det at hun er 100% å stole på ???
Hvem ??? TANITA ...... selvfølgelig !
Oppdager plutselig noe jeg ikke har lest før.......(da jeg lette etter noe heeeeelt annet !) OK, jeg VET at det er i reklamen for noe annet.... men www.mybodycomp.com er gratis !

The Truth About Body Fat Scales!
New body fat scales claim to measure body fat quickly and conveniently. At first glance they seem to be a great deal - using the "Bioelectrical Impedence" method to calculate your body fat. Unfortunately, these scales are notoriously innaccurate.
To make matters worse - they can only provide you with a limited understanding of your body composition.
All home body fat scales use the Bioelectrical Impedance method to measure your body fat percentage. With this method, a low-level electrical current is passed through your body and the impedance, or opposition to the flow of current, is measured. The result is used in conjunction with your weight and other factors to determine your body fat percentage.
Unfortunately, your body's impedance level can be altered by many factors besides body fat. These factors include:
- eating
- drinking
- dehydration level
- exercise
- menstrual cycles.
[left]This means that you can change your body fat percentage just by drinking a few cups of water! Of course, you aren't really changing your body fat - but the scale will say you are.

Only by following very strict rules can you hope to get an accurate measurement of your body fat using these scales. These rules include:
- No eating or drinking within 4 hours of the test
- No exercise within 12 hours of the test
- You must urinate within 30 minutes of the test
- No alcohol consumption within 48 hours of the test
- No diuretic medications within 7 days of the test
- Females who perceive they are retaining water should not use this method for body fat measurement during the menstrual cycles.
[left]Obviously following all these rules makes the test very impractical -especially if you want to chart your progress on a daily or weekly basis.
Additionally, some studies have shown variances as high as 8% when using the bioelectrical impedance method even if the rules are precisely followed. This means that a male testing at 16% body fat using these scales could actually have body fat as low as 8% or as high as 24%.

The inaccuracy between these figures would move you from being in peak physical shape to being considered very obese!
[left]Besides being grossly inaccurate - body fat scales only measure body fat percentage, not where your body fat is stored or any of the other valuable information you can gain through MyBodyComp.com.

OG SÅ OM HVORFOR WWW.MYBODYCOMP.COM LIKSOM SKAL VÆRE BEDRE:
Is This Accurate?
More than 50 years ago Dr. Albert Behnke discovered a phenomenal method for finding the composition of a body (measuring body fat) by weighing people while they were submerged underwater. This method, called hydrostatic weighing, has become the standard by which all other methods of measuring body fat are compared. Unfortunately, hydrostatic weighing requires specialized, expensive equipment that most people don't have access to.
Other methods to measure body fat do exist, such as Bioelectrical Impedence, Near-Infrared and X-Ray. However these other methods also require expensive equipment or skilled technicians to properly administer.
Plus, many of these methods of measuring body fat can have large errors due to clients exercising, eating or drinking, and in women, due to the menstrual cycle. Even when properly administered, the accuraccy of these othe methods has been questionable.The most popular method of measuring body fat is the use of skin fold calipers.Skin fold calipers are inexpensive and seem simple to use, but actually require extensive training to use properly. There is often much error in making the measurements, even among trained scientists.
During his research with hydrostatic weighing Dr. Behnke made an astonishing discovery. He noticed a strong connection between measurements of the circumference of certain areas of the body and a person's body fat levels.
In fact, he was able to determine body fat with the same accuraccy as hydrostatic weighing using nothing more than these circumference measurements.
For the first time there was a simple to use, highly accurate, reproducible method of measuring body fat. Known as the "body circumference technique", the method also measures where the body's muscle and fat is out of proportion - something no other method was able to do (including hydrostatic weighing).
MyBodyComp.com uses the body circumference technique and formulas based on the newest scientific research to monitor and track your body fat. These formulas give you the exact same accuracy as hydrostatic weighing - without the associated costs or need for specialized equipment.
Because MyBodyComp.com relies on a simple "low-tech" tool (the measuring tape) that anyone can use you'll get easy, accurate results, time after time.
[indent]"The use of girth measurements is a simple and practical method of estimating fat weight and lean weight in obese men."
-Arthur Weltman, PhD
Human Biology 59(3):523-535, 1987"A combination of circumferences results in an accurate prediction of fatness for all subjects," and, "the practical significance of this is obvious: percent body fat can be predicted easily from a few simple circumference measurements."
-Drs. Frank Katch and William McArdle
Nutrition, Weight Control, and Exercise, 2nd Edition 1983"The anthropomorphic technique (circumferences) provides rapid estimates of body fat and lean bodyweight (muscle). In addition, the method points out anatomic interrelationships and outlines body patterns which are beyond the scope of the techniques now employed for purely compositional analysis."

Jeg har ikke greie på dette, men syns det høres logisk ut. Hva sier dere som bruker vekter ala Tanita og har lært om hvordan det funker ?
