So I've just bought a scales which tells you your body fat percentage (not BMI), but I have no idea whether mine is good or bad!
It says 18.3, I weigh 112 and am 5'3. It also says my body water percentage as 53.4, what does it all mean!!?
Hello Pretty Lady,
What scale do you have? The scales use bioelectric impedence to measure body fat. They send a small current through your body. The current takes longer to go through fat than muscle.
These are usually accurate to about 4%. So your body fat could be from 22.3 to 14.3. This method also will produce different results based on your hydration. So its best to take a couple readings throughout the day. Also do not use it right after you work out because your hydration will be off. I have a Omron HBF-500 it seams to be pretty accurate.
For your stats that sounds about right.
Here is the information about body fat:

Also body water percentage:
Hope that answers your questions!
should your BMI be different than your body fat %?
How can your body fat% be like 38% but you have 100lbs to lose
Your BMI more than likely will not be the same as your Body Fat % because the two are completely different.
The BMI (Body Mass Index) is calculated by your height, age, and weight. It does not take into account how much muscle/mass you have or your frame size. It gives a broad weight range to cover a majority of people. There are plenty of athletes that are technically overweight by BMI standards but have low body fat percentages.
The BF% (Body Fat Percentage) is the percentage of fat that your body contains.
Here is a great article about Body Fat Percentage.
"For women, a body fat of 10-12% is essential, 14-20% is considered a healthy range for athletes, 21-24% is healthy for fitness, 25-31% is considered an 'acceptable' range and anything above 32% is considered obese.
For men, 2-4% body fat is essential, 6-13% is an athletic body fat range, 14-17% is considered a 'fit' range, and 18-25% is acceptable. Anything above 26% for men is considered obese. So, how do you find out what your body fat is? Below are the most popular methods for testing body composition."
ok that's a much better explanation because I kept seeing the 25 to 31 range..and for having a large BMI and not so large a BF% I was wondering..am I calculating something wrong?
thanks for the clarification
No problem. :)
Someone can have an "overweight" BMI but still be on the thin side because they have a lower body fat percentage. Just like someone with a healthy range BMI can look overweight because they have a high body fat percentage.
